UPDATE query is not working

hello all,
i'm using PHP and MS ACCESS database now i'm updating the table in a while loop. but it is giving error like...

Warning: odbc_exec(): SQL error: [Microsoft][ODBC Microsoft Access Driver] Syntax error in UPDATE statement., SQL state 37000 in SQLExecDirect in c:\apache\htdocs\allocater.php

and my update query is look like this....
$update = "UPDATE allocate3 SET WORKSHEDULE='$work',TIME='$now_date' WHERE auto_id='$id'";
$sql_result = odbc_exec($conn,$update);

what may be the problem please help me regarding this????

 

run the update query in access, it should give you a better error message. But as a first guess i would say its your "auto_id='$id'" im assuming the auto_id is an AutoNumber or Number so it shouldnt have single quotes around the val "auto_id=$id"

 

yes you are correct "auto_id" is AutoNumber. i'll try taking out the quotes around the value of auto_id. but i think that is not the problem....

 

Try writing your SQL string to the browser before actually attempting to update the DB.

Are the values you expected in it?
