Question

这是我在mysql中的商店程序。当我在phpmyadmin中调用它时，确定并完成了打电话给phpmyadmin
CALL sp_del_temp_record（＆＃39; tbl_user_login_and＆＃39;，1880,10） 但是当我在mysql_query中使用它时它不起作用：
mysql_query（＆＃34; CALL sp_del_temp_record（＆＃39; tbl_user_login_and＆＃39;，1877,10）＆＃34;）;
这是我的sp：

CREATE PROCEDURE `sp_del_temp_record`(p_tbl varchar(255),  max_record smallint(6),del_count smallint(6))
BEGIN
    SET @count_query=CONCAT ("select count(auto_id) into @count_record from ",p_tbl);
    PREPARE count_record_q FROM @count_query;
    EXECUTE count_record_q;


    if @count_record>max_record then
        SET @del_query=CONCAT ("delete from ",p_tbl," order by auto_id asc limit ",del_count);
        PREPARE del_query_q FROM @del_query;
        EXECUTE del_query_q;
    end if;    
   END;

Answer 1

尝试这种方式：

DELIMITER $$
CREATE PROCEDURE `sp_del_temp_record`(p_tbl varchar(255),  max_record smallint(6),del_count smallint(6))
BEGIN
    SET count_query=CONCAT ("select count(auto_id) into count_record from ",p_tbl);
    PREPARE count_record_q FROM count_query;
    EXECUTE count_record_q;


    if count_record>max_record then
        SET del_query=CONCAT ("delete from ",p_tbl," order by auto_id asc limit ",del_count);
        PREPARE del_query_q FROM del_query;
        EXECUTE del_query_q;
    end if;    
END$$

DELIMITER ;

Answer 2

$thisGuy = new MySQLI(inputParamsHere);
$retVal = $thisGuy->multi_query("CALL myDB.storedProc($var1, $var2, @return1, @return2); 
select @return1 as firstValue, @return2 as secondValue;");
if ($retVal) getResultSets();

尝试使用mysqli multi_query

public function getResultSets() {
$retVal = array();
do {
    if ($result = $this->mysqli->store_result())
        $retVal[] = $result;
} while ($this->mysqli->next_result());
return $retVal;

}

在PhpMyAdmin中调用存储过程是可以的，但作为查询运行并不起作用
