-1012: Too many referential constraint definitions for this table
Explanation:
Using the ALTER TABLE statement, the attempt was made to create more than 256 REFERENTIAL CONSTRAINT DEFINITIONS for a table that is the referencing table.
User Action:
Use a QUERY statement issued on the system table DOMAIN.COL_REFS_COL to check the existing CONSTRAINT definitions. The ALTER TABLE statement can only be issued once an existing CONSTRAINT definition has been deleted. Otherwise, do without the new CONSTRAINT definition.
