Subject: [SQL] prepared query plan did not update

Good morning,

I tried to use prepared query plan to update columns, but it did not
update at all.

PREPARE pname(varchar) AS
UPDATE t1
SET    col1 = false
WHERE  col1 AND       col2 = '$1' ;
EXECUTE pname( 'value' )



Could someone tell me where I did wrong please?

Thanks alot!

WHERE  col1 AND       col2 = '$1' ;
Are you looking for both: col1 and col2 - to be equal to '$1'?
Then it should be:
WHERE  col1 = '$1' AND       col2 = '$1';
