maxdb_num_rows

maxdb::num_rows

Gets the number of rows in a result

&reftitle.description;

&style.procedural;

`int` `maxdb_num_rows` `resource` `result`

&style.oop;

`int` `maxdb->num_rows`

Returns the number of rows in the result set.

The use of `maxdb_num_rows` depends on whether you use buffered or unbuffered result sets. In case you use unbuffered resultsets `maxdb_num_rows` will not correct the correct number of rows until all the rows in the result have been retrieved.

&reftitle.returnvalues;

Returns number of rows in the result set.

If the number of rows is greater than maximal int value, the number will be returned as a string.
