Question

I’m new to MySQL and databases in general. I’m trying to create a MySQL stored procedure but keep getting a vague syntax error:
“you have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘sps; EXECUTE stmt USING nn,ee,ll,cc,uu; COMMIT END’ at line 11”

If I remove the line “PREPARE stmt …” then the stored procedure is created. When I put the line back in, I get the error again.

What is it that I am doing wrong?

DELIMITER //
CREATE PROCEDURE `account_create` (nn VARCHAR(25),
                                   ee BIGINT, 
                                   ll BIGINT, 
                                   cc VARCHAR(100),
                                   uu VARCHAR(25))
   BEGIN
      DECLARE newId BIGINT;
      DECLARE sps VARCHAR(50);
      START TRANSACTION;
      set sps = 'INSERT INTO account SET name=?, entity=?, ledger=?, tblname=tmpXXX,  creation_date=CURDATE(), comment=?, uname=?';
      PREPARE stmt FROM sps;


      COMMIT;
   END//

You must use a User Defined Variable to execute a prepared statement. Rewrite as:

...
BEGIN
  DECLARE newId BIGINT;

  START TRANSACTION;
  set @sps = 'INSERT INTO account SET name=?, entity=?, ledger=?, tblname=tmpXXX,  creation_date=CURDATE(), comment=?, uname=?';
  PREPARE stmt FROM @sps;


  COMMIT;
END//
