php - Why this stored procedure doesn't work? -


it doesn't seem there problem, can't understand why doesn't return data.

this stored procedure:

delimiter $$ drop procedure if exists `test`.`get_products`$$ create procedure  `test`.`get_products` (     out out_productname varchar(255) ) begin select productname out_productname products; end $$ delimiter ;

and how call it:

$rs = mysql_query( 'call get_products(@f)' ); $rs = mysql_query( 'select @f' ); while($row = mysql_fetch_assoc($rs)) { print_r($row); }

this doesn't quite answer question work around not use output parameter

delimiter $$ drop procedure if exists `test`.`get_products`$$ create procedure  `test`.`get_products` (  ) begin select productname @f products; end $$ delimiter ;    mysql_query( 'set @f = 0;' ); $rs = mysql_query( 'call get_products()' ); $rs = mysql_query( 'select @f' ); while($row = mysql_fetch_assoc($rs)) { print_r($row); }

@f maintained database , can accessed sql session, if remember correctly

also in event returning things while getting results stored procedure want use

$rs->close();  $connection->next_result();

connection whatever named connection string
