75 ways to demystify DB2: #7 : Tech Tip: How to disable multirowinsert support in DB2 JCC application?
Body
In DB2 JDBC applications, when you execute INSERT or MERGE statements that use parameter markers in a batch, if the data server supports multi-row INSERT, the IBM Data Server Driver for JDBC and SQLJ can transform the batch INSERT or MERGE operations into multi-row INSERT statements by default.
If INSERT FROM SELECT statements are executed in a batch, the driver will throw a BatchUpdateException, by default and its a restriction.
To avoid the exception, JCC datasource property enableMultiRowInsertSupport must be set to false.
The property can be set to false as below:
In application code: ((com.ibm.db2.jcc.DB2BaseDataSource)ds).setEnableMultirowInsertSupport(false);
(or)
In application server datasource properties, set enableMultiRowInsertSupport=false for the specific datasource.
(or)
you can set the JVM property: -Ddb2.jcc.override.enableMultirowInsertSupport=false in the configuration files. For example in Tomcat, tomcat.ini file.
