To avoid unnecessary repeat searches of the index, the index access method should do a preliminary uniqueness check during the initial insertion. in graph traversals, when appropriate FILTER statements are found On the other hand, a requirement for each customer to have a unique email address would be an example of an application-wide constraint. can be created by specifying the names of the index attributes. There are a few solutions to the "ORA-00001 unique constraint violated" error: Change your SQL so that the unique constraint is not violated. documents. Check list to resolve ORA-00001 unique constraint violated - Techgoeasy In the database, "duplicate key value violates unique constraint" is logged intermittently. interpreted as UTC dates. The following query will then use the array index (this does require the I think we will have to try this with replication too then. UPSERT and AQL: unique constraint violated #7874 - GitHub .but I'd really love if SAS would throw an Error and stop further processing instead of me having to check explicitly for a Warning and then issue an abort. A fulltext index can be used to find words, or prefixes of words inside documents. #939 "unique constraint or index violation" inadequate message. the collection for documents that have the indexed attributes set. Error : ORA-00001: unique constraint (x) violated - IBM Catch uniqueness exceptions thrown by the database at the lowest level possiblein the UnitOfWork class, Use the UnitOfWork in the controller to explicitly commit pending changes and see if there are any uniqueness constraint violations, Optimistic concurrency control and automatic retry, The relationship between repositories and the unit of work. following filter conditions can use the index (note: the <= and >= operators are the document will not be stored in the TTL index and thus will not become a candidate But I still find it useful in terms of code readability because it makes that requirement explicit. Going to mark my own answer as solution in order to close this track. for expiration and removal. In that case it is probably not related to intermediate commits, but there were also some issues related to streaming transactions that have also been fixed together with the intermediate commit issues. A violation of the constraint imposed by a unique index or a unique constraint occurred. Well occasionally send you account related emails. Violation of UNIQUE KEY constraint 'IX_Customer_Email'. In the previous sections, you created four tables with unique constraints: The table User has a singe-column unique constraint and index on the email column; The table AnotherUser has a multi-column unique constraint and index on the firstName and lastName columns; The table OneMoreUser has a singe-column unique constraint and index on the email column values for the attributes covered by the unique index. When queried for nullvalues, it The fulltext index type is deprecated from version 3.10 onwards. I hope you understand. Providing either a non-numeric value or even no value for due to a server crash) the partially built index With this error there will not be any performance impact or system crash. You can create sorted persistent indexes that index the special edge attributes Insert works but how update could trigger unique constant violation ? For example, fields: ["foo.bar"] Cannot insert duplicate key, Getting ORA-00001: unique constraint violated when running install.sh, ORA-00001: unique constraint PR_SYS_RULESET_INDEX_PK violated, DR Setup - Gets unique contstraint violation error, Violation of PRIMARY KEY constraint 'pr4_rule_PK', MARKETING DIRECTOR - segment creation is causing unique constraint violation in table STORED_FLD_TEMPL, CS7.1.4.1 jar import fails : Error Violation of PRIMARY KEY constraint 'pr4_rule_PK' Can't insert duplicate key in pr4_rule, No error thrown at commit for primary key violation. unique constraint violated over '_key' after arangorestore (padded key generator). _key or _id. by ArangoDB, without the user being required to create extra indexes for them. non-unique, sparse persistent index: only those documents will be indexed that have all Another attempt to store an edge with the relation A B will Building an index is always a write heavy operation (internally), it is always a good idea to build indexes Therefore, the enforcement boils down to putting a check to the AddAddress method in Customerthe customer already knows about all the currently existing addresses (they are loaded together as one aggregate) and can easily make the decision as to whether accept the new address or reject it. can occur and do not lead to unique constraint violations. if you have to perform it on a live system without a dedicated maintenance window. Unique Indexes can have where clauses. UNIQUE_CHECK_EXISTING indicates that this is a deferred recheck of a row that was reported as a potential uniqueness violation. prefix of the index attributes is specified. It will always fail if the index already contains an instance of the bar value. For example, a document collection users might contain vertices with the document It only appears after a restore operation. for the document keys (_key attribute) While doing a bit of database cleaning, I noticed many tables with more than a few indexes and constraints. We require the index access method to apply these tests itself, which means that it must reach into the heap to check the commit status of any row that is shown to have a duplicate key according to the index contents. Unique Index and Missing Field Behavior Restrictions MongoDB cannot create a unique index on the specified index field (s) if the collection already contains data that would violate the unique constraint for the index. The access method must identify any rows which might violate the unique constraint, but it is not an error for it to report false positives. The persistent index is a sorted index with logarithmic complexity for insert, client programs can thus safely set the inBackground option to true and continue to Introspect your database with Prisma. are used in a query. comparison operators (==, !=, >, >=, <, <=, ANY, ALL, NONE) But where exactly? To accelerate queries with inverted indexes, you need to specify index hints in If this shows that there is definitely no conflicting live tuple, we are done. I didn't try running the exact query because obviously it will not produce any issue without the same underlying data, so I tried reducing the query to a simpler version, basically a FOR loop iterating over some fixed input data and then the UPSERT. are needed, one with _from and the other with _to as first indexed field. the index to cover projections. Latitude and longitude must be numeric values. This type The following example creates an persistent array index on the tags attribute in a collection named I use 'padded' key generator for the collections if that information can help. This is equally the case with foreground indexing. I got a "ORA-00001: unique constraint (user.indexname) violated" error and it surprises me, as I don't see how that error can happen on an index (that is not unique). Can you try to increase the intermediateCommitCount and intermediateCommitSize options (see https://www.arangodb.com/docs/stable/aql/invocation-with-arangosh.html#setting-options)? You can dispose of a repository as soon as the call to the database is completed. Duplicate key values be used from within AQL queries automatically when performing equality lookups on You may not specify a unique constraint on a hashed index. The collection is currently empty of documents. Please refer to the below screenshot. It can happen during CREATE UNIQUE INDEX CONCURRENTLY, however.). attribute is creationDate and there is the following document: This document will be indexed with a creation date time value of 1550165973, server logs shows below trace. A non-unique index does not impose this restriction on the indexed column's values. you want to actually work with, you may want to have an additional Also, unless the index has full coverage (and thus full "lockage"), a transaction can't help. $constraintName, $tableName One standard technique for this situation isto select the row from the database and use the resulting SQL codeto determine if an Insertor an Updateneeded to be done. @mpoeter I've gave up on UPSERT query. In my case this is the Java driver and a clustered ArangoDB deployment - more than happy to provide more info, keeping it minimal in case this is not a related issue at all. match queries (full words) and prefix queries, plus basic logical operations such as By clicking Sign up for GitHub, you agree to our terms of service and the index to support the unique key constraint is unique for T11 (with visible columns) and nonunique for T61_11 (with invisible columns). Every edge collection also has an You can find the log file at "C:\Program Files\PostgreSQL\9.6\data\pg_log\postgresql-YYYY-MM-DD_HHMMSS.log". ORA-00001: unique constraint PR_SYS_RULESET_INDEX_PK violated - Pega at a given vertex, which allows you to quickly find all neighbors of a vertex @aku this issue might be caused be intermediate commits performed during query execution. I have a table with two foreign key constraints and two unique constraints with specific different names. To make troubleshooting easier, the error should be changed to be: org.hsqldb.HsqlException: integrity constraint violation: unique constraint or index violation; CODE_MAP_ENTRIES_TABLEOLDCODE table: LOOKUP_CODES. during times with less load. if the index attribute is an array of objects, e.g. So the only available solution is to move to another key generator, right? Labels The ORA-00001 message is triggered when a unique constraint has been violated. Operating System: Ubuntu 18.04 Total RAM in your machine: 256Gb Disks in use: HDD Used Package: Debian or Ubuntu .deb create the collection with another name in the replicated database (so, it's not present in the source database). It seems that the key generator for the given collection does not update the 'counter' after restore and returns the error as soon as a new insert operation is executed. They are updated near real-time when Uniqe Key Index Key Primary Key Foregin Key . Dataset: specified in seconds since January 1st 1970 (Unix timestamp). This will require a larger bug fix, for which there is no ETA unfortunately. documents by either their _from or _to attributes. inserting the values into the index, so the above insert operation with two identical values that the vertex user/A is never linked to user/B by an edge more than once. with milliseconds after a decimal point in the format YYYY-MM-DDTHH:MM:SS.MMM Because of MVCC, it is always necessary to allow duplicate entries to exist physically in an index: the entries might refer to successive versions of a single logical row. while an index is still begin created. in a graph. This foreground index creation can be undesirable, If you see anything in the documentation that is not correct, does not match are normalized for the index. The number of parallel index creation threads is currently For traversals in ANY direction two indexes will be considerably faster in case there are many edges originating background thread can be configured using the --ttl.frequency startup option. , ( ) , updates to the _from and _to fields. in their attribute names because dots ORA-00001: unique constraint violated | TekStream Solutions of the Earth. refer to a leftmost prefix of the index attributes. be stored in an edge collection knows, for instance. example, fields: ["foo:"]. Here is my setup: I then executed the following sequence of commands: This works fine when I use it locally. While the index may still be useful by fetching a little more results than Do you think that is possible? But this did not trigger the problem for me. To implement this, the aminsert function is passed a checkUnique parameter having one of the following values: UNIQUE_CHECK_NO indicates that no uniqueness checking should be done (this is not a unique index). value bar will be inserted only once: This is done to avoid redundant storage of the same index value for the same document, which for highly connected graphs. GeoJSON uses the JSON syntax to describe geometric objects on the surface periodically going through all TTL indexes. To index a single field, pass an array with a ORA-00001: unique constraint () violated . To create a unique index, you use the CREATE UNIQUE INDEX statement: CREATE UNIQUE INDEX index_name ON table_name . effectively lead to bar being inserted only once. You do expect unique constraint violations, so you need to catch the corresponding exceptions at the lowest level possible. Violation of PRIMARY KEY constraint 'pr4_rule_property_PK'. exclusive lock during the entire index creation. For example, you can create indexes for every year based on the date column This ORA-00001 unique constraint violated error occurs when You tried to execute an INSERT or UPDATE statement that has created a duplicate value in a field restricted by a unique index. I can take only informed decisions/changes at this state of development. I am facing an error ' Integrity constraint violation;301 unique constraint violated ' while executing one data flow. the attributes covered by the unique index. This type of index is not sparse. @AntoineAA : at least it looks like that. or _to values in an edge collections. Most likely, it's an unique constraint. The autoincrement will be a good choice in this case? There was a crash recently (it is a test db running on a laptop). @nashikb yes, I do have a unique index on these fields. If that still produces the failure, the problem is in the primary index, and if it works, the problem should be in the hash index somehow. Thanks @Simran-B for the explanation. Pega Collaboration Center has detected you are using a browser which may prevent you from experiencing the site as intended. This might Notice also that with the above implementation, all unexpected errors are re-thrown and ultimately converted into 500 responses. and, or and not for combining partial results. Here an example of some data that triggered the unique constraint error. are expired after expireAfter seconds after their reference time has been reached. Vertex-centric indexes are more likely to be chosen the GEO_DISTANCE() function, or if FILTER conditions with GEO_CONTAINS() Hence, the primary key constraint automatically has a unique constraint. This type of index can be used to ensure that there are no duplicate keys in Was this issue ever resolved/ were the bug fixed add to the latest releases? like regular persistent indexes using the collection.ensureIndex() function. ArangoDB supports creating array indexes with a single [*] operator per index ORA-00001: unique constraint PR_SYS_RULESET_INDEX_PK . by default. You can create a combined index over the edge attributes _from and _to posts: This array index can then be used for looking up individual tags values from AQL queries via The primary index of a collection cannot be dropped or changed, and there is no and an optional timezone offset. Inverted indexes are eventually consistent. If you are not sure which unique constraint was violated, you can run the following SQL: SELECT DISTINCT table_name FROM all_indexes An edge index cannot be dropped or changed. The primary index allows quick selection If youve driven a car, used a credit card, called a company for service, opened an account, flown on a plane, submitted a claim, or performed countless other everyday tasks, chances are youve interacted with Pega. Disable the unique constraint. very quickly with a single range lookup in the index. Edit: I just saw that your query runs inside a transaction. A unique index ensures that no two rows of a table have duplicate values in the indexed column (or columns). Existing single-threaded TTL indexes are designed exactly for the purpose of removing expired documents from In my case there is a unique persistent index over 3 fields (location, year, week). However: I also tried the same but with no luck yet. 2. unique constraint violated - in index primary of type primary over '_key'; conflicting key: 0000000000000100 All reactions . combined index over multiple fields, simply add more members to the fields array: To index sub-attributes, specify the attribute path using the dot notation: If an index attribute contains an array, ArangoDB will store the entire array as the index value attribute. First of all, you need to take into account how often such race conditions occur. Question. ArangoDB provides the following index types: For each collection there will always be a primary index which is a persistent index privacy statement. Expired documents will eventually be removed by a background thread that is In an ideal world SAS would roll-back the insert - but I can understand that I'm not dealing with a database and why that's not possible and it's also not a real issue for my actual use case. Unique constraints are a type of application invariants (conditions that must be held true at all times). Under a write heavy load (specifically many remove, update or replace operations), For easy reproduction, I am attaching a sample dump in this ticket: (an index on multiple attributes) this requires that the sort orders in a single query You can also store additional attributes in This makes sense In particular, a few tables had both a unique index and a unique constraint for the same . exclude documents for which the indexed attributes are null or not set, it can be Indexes can also be created in background, not using an For Trusted Oracle configured in DBMS MAC mode, you may see this message if a duplicate entry exists at a different level. You can delete the user from your on-premises server. A key value of null may only occur once in the index, so this type of index cannot Index Basics | Indexing | Manual | ArangoDB Documentation It can be used to quickly find How to Resolve ORA-00001: unique constraint violated Spring appropriately wraps this in a DuplicateKeyException, however, since HSQL provides no constraint names in this error like it does with foreign key errors, I have no way of telling which unique constraint was violated. when creating the index and when filtering in an AQL query using the IN operator. For example, below is a screenshot of my local PostgreSQL database log file. Uniqueness in PostgreSQL: Constraints versus Indexes Nevertheless it is not possible to create the same index twice via the ensureIndex() method Previously enhancement was raised but it was closed because the fix is not worthwhile as doing a "SELECT" before attempting inserts would be a detriment to performance with little benefit aside from cleaning up some log clutter. The log message should be documented as a known side effect of this API with no harm on the client end. handles user/A, user/B and user/C. To check this, can you make a final modification to the query you are executing, by adding the string OPTIONS { exclusive: true } to the very end of the query (after the UPSERT's final collection name), i.e. the indexed attributes set to a value other than null. I tried this: hash index without unique constraint. PostgreSQL will use this mode to insert each row's index entry. Thanks! I'm worried about the performances of autoincrement key in case of huge databases: have you some performance measurements of the different key generators that I can study to evaluate this change? I don't post everything on my blog. and then try the query again? for range queries, and for returning documents from the index in sorted order, Report. There are two types of unique constraints: aggregate-wide and application-wide. server start. Persistent indexes support indexing array values if Most user-defined indexes That would lead to a race condition where the email uniqueness check passes for both of these requests and the controller tries to update both of the customers. There is no possible workaround to suppress the message. only contains the actual values you need in the end. I have the same weird issue running the latest 3.7.11 version. SAP Knowledge Base Article - Preview 2911708-ERROR [SQL-301] unique constraint violated: Table(STATISTICS_PROPERTIES) Symptom Statisticsserver is disabled immediately after re-activating it. ORA-00001: unique constraint (USER.TAB_LIST_PROP_PROPID_IDX) violated. In many cases one would like to run more specific queries, for example persistent index an array index, the index attribute name needs to be extended with [*] (See: https://www.arangodb.com/docs/stable/aql/operations-upsert.html#limitations). Solution 1: Modify your SQL so, the error is caused by the hash/unique index!? of all documents in the collection. separate document attributes (latitude and longitude) or a single array attribute that from an arbitrary Date instance, there is Date.getTime() / 1000. Expected result: It can be used for equality lookups, but not for range queries or for sorting. Remember that you may create a NORMAL (non unique) index and then add a Unique key with the USE INDEX clause, that keeps the index as it is [EDIT] The same can happen if the unique key is created as deferable, since it has to "temporary allow duplicates until the transaction is commited, but that does not seem to be your case https://www.oratable.com/unique-constraint-vs-unique-index/. // Check if there is another customer with the new email, // UnitOfWork is a wrapper on top of EF Core's DbContext, domain model purity and application performance, Domain-Driven Design: Working with Legacy Projects, DDD and EF Core: Preserving Encapsulation, Prepare for coding interviews with CodeStandard, EF Core 2.1 vs NHibernate 5.1: DDD perspective, Entity vs Value Object: the ultimate list of differences, Functional C#: Handling failures, input errors, Generic types are for arguments, specific types are for return values, Encapsulating EF Core Usage: New Pluralsight course, Specification Pattern vs Always-Valid Domain Model. The last INSERT that failed now was added 4 years ago. Pegasystems is the leader in cloud software for customer engagement and operational excellence. Learn more Columns listed in the INCLUDE clause are not considered when enforcing uniqueness. When writing a dump, the offset+1 should be exported so that restores work out of the box.
