Hi Most databases don't return the number of rows in the results of a select statement to odbc_num_rows. See:
http://www.php.net/manual/en/function.odbc-num-rows.php Usually the way to determine the number of rows a select returns is to either fetch them all and count them or do an additional aggregate query. It depends on your requirements. I presume that this behaviour is because in most cases the database engine does not make the number of rows in a result set available to the driver. The only way the php interface could calculate the number of rows would be to fetch them all which may be inefficient - say if you were only interested in the first row out of a possible 100. [anybody else care to comment?] Note, after an insert, update and delete statements odbc_num_rows does return the number of rows affected. cheers Simon On Tuesday 09 November 2004 08:09, Petrus Ali Saputra wrote: > Here is my code: > $conn = odbc_connect("Ta Fara","",""); > $query = "SELECT * FROM Config"; > $result = odbc_exec($conn, $query); > echo odbc_num_rows($result); > > This code never give me a 0 result even there is some data.
