I had to drop a test table and load it with data from my production environment which has an IDENTITY column that is automatically incremented by DB2. When I dropped the table, this of course gets reset to 1 and now I get dupes when trying to insert into the table.
I have searched the internet for a solution and gotten no where. Please help me set my identity column to 1905. Thanks Sad

pcmoonbeam,

Use the ALTER Command to restart the identity column from 1905 .

ex: (untested)

Code:

ALTER TABLE <your table name> ALTER COLUMN <id col name> RESTART WITH 1905
