DB2: Using NOT EXISTS with SYSIBM.DUAL in a complex batch query
Joined: Nov 27, 2008

I have data in a
object as data1, data2.
data1 and data2 together forms a composite key in myTable where I want to insert the object.
The writing is happening as a batch. Like 10 insert statements are prepared using 10 objects and are executed as a batch.
I want to insert the above data with the constraint: data1 + data2 should not already be present in myTable i.e. data1 + data2 should be unique --- if unique then write else just ignore.
The query I am using is:
Insert into mySchema.myTable(column1, column2) select 'abc', '123' from SYSIBM.DUAL where not exists (select 1 from mySchema.myTable A where 'abc' = A.column1 and '123' = A.column2)
Running above query independently for single set of data runs successfully.
However, while running in batch scenario I am getting "com.ibm.db2.jcc.b.ie: Non-atomic batch failure." error.
I think it has something to do with using SYSIBM.DUAL in batch scenario.
I agree. Here's the link:
