Hi,

please ammend this SQL code to select records if A1 and A2 fields are Null value. I used '' but it doesn't give me correct answer.

"select * From Table1 Where (((Table1.A1) = '')  And ((Table1.A2) = ''))"

Thanx

try:

SELECT * FROM [Table1] WHERE (([Table1].[A1] IS NULL) AND ([Table1].[A2] IS NULL));

-or-

SELECT * FROM [Table1] WHERE (([Table1].[A1] = NULL) AND ([Table1].[A2] = NULL));

j_a_delooze,

If this is MS SQL Server the second solution will not return any values.  Reason: Null <> Null
