dumb question

Sorry about this. But I've worked primarily in access for years.

Does SQL Server have a boolean or a yes/no data type for its table columns?

Thanks in advance,

No, and you should not write SQL that way -- bit flags are too low
level for a high level language. We left BOOLEANs out for good
reasons having to do with 3VL, NULLs and consistent language model.|||Hi Bill,

No it doesn't, people usually use the BIT data type which holds 0 or 1; some
folk like myself use Y or N / T or F in a char(1) column.

Tony.
