hi, have You ever heard of KeySchemaTable UseCachingTable flag? We have got a solution to IN list limit (at 1000) that this can be circumvented by turning off such flag. I searched db reference, hidden parameters (despite of different convention), MOS and google - no hits Below citation from support "the error found: java.sql.SQLSyntaxErrorException: ORA-01795: maximum number of expressions in a list is 1000 is due to a typical Oracle limitation of max 1000 expressions in IN(from sql syntax). It can be solved by turning off the KeySchemaTable UseCachingTable flag."
