Subj:   Re: Which tables are multiset?
 
From:   John Hall



I'm probably being anal, but as it applies to a Table, the CHECKOPT flag really doesn't indicate whether a table is SET or MULTISET, but rather whether duplicate row checking will be skipped. By experimentation, here are the settings of the CHECKOPT flag:

- If a Table is defined as a SET Table, then this Column will contain 'N'.

- If a Table is defined as a MULTISET Table and has a UPI, then this Column will contain 'N'.

- If a Table is defined as a MULTISET Table and has a NUPI, then this Column will contain 'Y'.

So as long as your sure that you'll never define a MULTISET table as having a unique primary index, then yes, you can use CHECKOPT.
