Assuming that 'A' and 'Foo' above are placeholders and neither actual strings nor column names, the query looks mostly fine. What does the following return? SELECT * FROM AlertErrors WHERE id = A and code = Foo and subCode = 0 Of course, if A and Foo are actual strings, then you have to enclose them in single quotes. > > Two rows of data should be returned, I've tried this on other SQL > engines like SQL Server Compact and it returns both rows as expected.
