searching empty coloumns
i have a little problem. How can i search for empty coloums. Say, there is an Coloums "File" and there is nothing saved. (THis coloums is also untouched.) How can i search for Rekords with this coloumn "file" empty.
SELECT * FROM Table WHERE file LIKE '' doesn't work.
SELECT * FROM Table WHERE file LIKE NULL returns a syntax-error. :-(
Please help me, thanks.

WHERE Mycolumn IS NULL
Do note, that it "MyColumn" is a character column, '' is not the same as NULL, unlike in Oracle.
