Question

I am using DB2 for my application. I run some insertion script after creating database. That insertion script generates records in table with id’s given in insertion script.

Suppose for abc table insertion script creates a record with id = 3. As id’s are set to auto generated in hibernate so while saving third record from application I got exception.

        Caused by: com.ibm.websphere.ce.cm.DuplicateKeyException: One or
 more values in the INSERT statement, UPDATE statement, or foreign
 key update caused by a DELETE statement are not valid
 because the primary key, unique constraint or unique
 index identified by "1" constrains table

I am using @GeneratedValue(strategy = GenerationType.AUTO)

What strategy = GenerationType I should use to overcome this problem.

Answer 1

Nothing works except this query.

alter table TABLE_NAME alter column ID set GENERATED BY DEFAULT RESTART WITH 10000;

DB2 should choose available ID itself but not doing so.
