jaisol Posted June 22, 2010 Share Posted June 22, 2010 I have the following code its from a php function. $query3 = "SELECT * FROM `client` WHERE `c_fname` = 'brick' LIMIT 0, 2"; $dog = mysql_query($query3); echo "<br> query result {$dog}"; The above code returns a resource ID I was expecting it to return false as there is no "brick" in the colum c_fname. Anyone know why its returning a resource id? Quote Link to comment https://forums.phpfreaks.com/topic/205563-unexpected-reource-id-from-a-select-query/ Share on other sites More sharing options...
Alex Posted June 22, 2010 Share Posted June 22, 2010 What makes you think it would return false? As you can see from the manual, mysql_query only returns false if the query fails or if the user does not have sufficient privileges to access the table.

PFMaBiSmAd Posted June 22, 2010 Share Posted June 22, 2010 The value from a mysql_query() will only be FALSE if the query fails due to an error (i.e. no connection to the database server, no database selected, a syntax error in the sql, a duplicate key...) A query that executes without any errors but matches zero rows is a successful query and returns a result resource, but the result set contains zero rows in it. You can use mysql_num_rows() to find out how many rows are in the result set.

jaisol Posted June 22, 2010 Author Share Posted June 22, 2010 Many thanks I'll count the rows to check my results, I wrongly thought if the query returned 0 rows then it would be unsucessful. I've learned otherwise ..
