为什么此SQL查询返回null？

Question

$sql_amorgia = "select * from fb_event where eventid='20'";
$res_amorgia = mysql_query($sql_amorgia);
$no_of_e = mysql_num_rows($res_amorgia);

When I print out $no_of_e it prints nothing. It should print 0 in case of null record. Isnt it?

please check!

Answer 1

Actually I was using mysql_num_rows() instead of mssql_num_rows() . Because the database I was using was MS SQL Server 2005.
