A relational database management system uses SQLMERGE also called upsert statements to INSERT new records or UPDATE existing records depending on whether condition matches. It was officially introduced in the SQL 2. An SQL INSERT statement adds one or more records to any single table in a relational database. SQL 2. 00. 8 standard. MERGEINTOtablename.

The four possible combinations yield these rules If the ON fields in the Source matches the ON fields in the Target, then UPDATEIf the ON fields in the Source does not match the ON fields in the Target, then INSERTIf the ON fields does not exist in the Source but does exist in the Target, then no action is performed. If the ON fields does not exist in either the Source or Target, then no action is performed. If multiple Source rows match a given Target row, an error is mandated by SQL 2. You cannot update a Target row multiple times with a MERGE statement. ImplementationseditDatabase management systems Oracle Database, DB2, Teradata, EXASOL, Firebird, CUBRID, HSQLDB, MS SQL, Vectorwise and Apache Derby support the standard syntax. Some also add non standard SQL extensions. SynonymouseditSome database implementations adopted the term Upsert a portmanteau of update and insert to a database statement, or combination of statements, that inserts a record to a table in a database if the record does not exist or, if the record already exists, updates the existing record. It is also used to abbreviate the MERGE equivalent pseudo code. It is used in Microsoft SQL Azure. Other non standard implementationseditSome other database management systems support this, or very similar behavior, through their own, non standard SQL extensions. My. SQL, for example, supports the use of INSERT. ONDUPLICATEKEYUPDATE syntax2 which can be used to achieve a similar effect with the limitation that the join between target and source has to be made only on PRIMARY KEY or UNIQUE constraints, which is not required in the ANSIISO standard. It also supports REPLACE INTO syntax,3 which first attempts an insert, and if that fails, deletes the row, if exists, and then inserts the new one. There is also an IGNORE clause for the INSERT statement,4 which tells the server to ignore duplicate key errors and go on existing rows will not be inserted or updated, but all new rows will be inserted. SQLites INSERTORREPLACEINTO works similarly. It also supports REPLACE INTO as an alias for compatibility with My. SQL. 5Firebird supports MERGE INTO though fails to throw an error when there are multiple Source data rows. Chick Corea Transcription Pdf File. Additionally there is a single row version, UPDATEORINSERTINTOtablenamecolumnsVALUESvaluesMATCHINGcolumns, but the latter does not give you the option to take different actions on insert versus update e. IBM DB2 extends the syntax with multiple WHEN MATCHED and WHEN NOT MATCHED clauses, distinguishing them with. AND some conditionguards. Microsoft SQL Server extends with supporting guards and also with supporting Left Join via WHENNOTMATCHEDBYSOURCE clauses. Postgre. SQL supports merging via INSERTINTO.
