p.s. so the test you posted is checking whether the column is a primary key

TimHumphries,
>>so the test you posted is checking whether the column is a primary key
I find that inconsistant. For example, all the rows in the result set have Status & 1 = 1, even for the AuditUserID column.

>>Pseudo-bit-mask indicating the status
I ran the following:
select
con.status & 1 'and 1',
con.status & 2 'and 2',
con.status & 3 'and 3',
con.status & 4 'and 4',
con.status & 5 'and 5',
con.status & 16 'and 16',
con.status & 32 'and 32'
from sysconstraints con
join syscolumns c on con.colid = c.colid and c.id = con.id and get the following- so you can see that Status & 1 is not helpful in pinpointing the PK.
