Question

The table[file_request ] structure:

user_id[INT]  file_id[CHAR(10)]  all_files

This is the SQL code which work fine in MySQL clien: I am using heidisql

DROP PROCEDURE IF EXISTS check_user_files;
DELIMITER \\  
 CREATE PROCEDURE check_user_files(IN p_user_id INT,IN p_file_id CHAR(10),IN p_all_files VARCHAR(500))
   BEGIN
        IF EXISTS(SELECT 1 FROM file_request WHERE user_id = p_user_id AND movie_id = p_file_id) THEN
            UPDATE file_request SET `requring_date`=NOW(),`all_files`= p_all_files WHERE `user_id`=p_user_id AND              `movie_id`=p_file_id;
        ELSE
            INSERT INTO file_request (`user_id`,`requring_date`,`movie_id`,`all_files`) 
            VALUES (p_user_id,NOW(),p_file_id,p_all_files);
        END IF; 
    END \\
DELIMITER ;
CALL check_user_files('23','T40431284','07 08 10 11 13 14');
DELIMITER ;
CALL check_user_files('23','F87951','01 02 03');

And I trying to create and execute the SQL query from PHP [didn’t work] :

// create the call procedure statements
foreach($fileData as $key=>$value){
    $callSP .= "DELIMITER ; \n
                CALL check_user_files('$userID','$key','$value');\n";            
}

$insert_file_request_query = "DROP PROCEDURE IF EXISTS check_user_files;
                              DELIMITER \\\\  
                              CREATE PROCEDURE check_user_files(IN p_user_id INT,IN p_file_id CHAR(10),IN p_all_files VARCHAR(500))
                                BEGIN
                                    IF EXISTS(SELECT 1 FROM file_request WHERE user_id = p_user_id AND movie_id = p_file_id) THEN
                                        UPDATE file_request SET `requring_date`=NOW(),`all_files`= p_all_files WHERE `user_id`=p_user_id AND `movie_id`=p_file_id;
                                    ELSE
                                        INSERT INTO file_request (`user_id`,`requring_date`,`movie_id`,`all_files`) 
                                        VALUES (p_user_id,NOW(),p_file_id,p_all_files);
                                    END IF; 
                                END \\\\
                              $callSP";

mysqli_query($conn,$insert_file_request_query);

The SQL query which created from PHP didn’t work as in the MySQL client!?

So, how can I fix it!?

[update1]

I found that the SQL query must in the special format [ the formate which work fine in the MySQL client] or shouldn’t work,I tried to copy and paste the query which echo from the PHP, the query code become one line and couldn’t execute in MySQL client,too.

[update2]
The code of create store procedure will work fine when I execute it alone from PHP.I mean,I split the whole process into three parts and execute them one by one.

part1: drop the procedure if it was exists; [using mysqli_query()]
part2: create the procedure;[using mysqli_query()]
part3：call the procedure;[using mysqli_multi_query()]

$insert_file_request_query = '';    

foreach($fileData as $key=>$value){
    $insert_file_request_query .= "CALL check_save_file_request('$userID','$key','$value');";            
}

mysqli_multi_query($conn,$insert_file_request_query);

And my final solution was to create the Store Procedure in MySQL and call it from the PHP.It works fine now.

Thank you very much!!

You can’t combine multiple statements in mysqli_query. Split out the definition of the stored procedure from the CALLs to it. If that still fails, we’ll need the full and exact error message that you receive.
