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//

It reported:
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 'while i>0 do
set exe_sql = concat('alter table test add column d ',i,' int'
at line 11
However my colleague and I have checked it many times, finding no issues in the syntax and getting more confusion.
This is my code in MySQL.
USE database;
DROP procedure IF EXISTS CreateTable;
DELIMITER $$
USE ims_data$$
CREATE PROCEDURE CreateTable ()
BEGIN
Set #SqlQuery = Concat('DROP TABLE IF EXISTS mytemptable;');
Set #SqlQuery = Concat(#SqlQuery,'\r\n','create table mytemptable');
Set #SqlQuery = Concat(#SqlQuery,'\r\n','(');
Set #SqlQuery = Concat(#SqlQuery,'\r\n','Column1 int,');
Set #SqlQuery = Concat(#SqlQuery,'\r\n','Column2 varchar(500)');
Set #SqlQuery = Concat(#SqlQuery,'\r\n',');');
Set #SqlQuery = Concat(#SqlQuery,'\r\n','Select * from mytemptable;');

I am trying to create a table but it is giving me an error.
Error Code: 1064. 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 'create table mytemptable (Stockist_Code int,Status varchar(500) ); Sele' at line 2
This is the output of query.
DROP TABLE IF EXISTS mytemptable;
create table mytemptable
(
Column1 int,
Column2 varchar(500)
);
Select * from mytemptable;
Which is working fine when executing this code withoug calling the procedure.
PREPARE/EXECUTE can only process one statement at a time. You're trying to execute two with the ;.
The error message gives you a clue in that it ran the two statements together.
You'll have to run them as separate statements.
I am creating a stored procedure which will be executing a prepared statement but on the creation the procedure I get mysql syntax error :
MySQL said: #1064 - 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 'PREPARE udpatestatut FROM #req; EXECUTE
updatestatut; DEALLOCATE PREPARE upd' at line 4
I don't see what my mistake is so I need help to understand what I am doing wrong or writting wrong. Here down is the instructions I am executing.
CREATE PROCEDURE changestatut(IN pstatut VARCHAR(10), IN pidpost VARCHAR(255))
COMMENT 'This procedure change the statut of activities.' NOT DETERMINISTIC NO SQL SQL SECURITY DEFINER
SET #req := concat('UPDATE compte set statut=\'', pstatut ,'\' where idpost in (', pidpost ,')');
PREPARE udpatestatut FROM #req; EXECUTE updatestatut; DEALLOCATE PREPARE updatestatut;
idpost parameter is a comma separated value ...e.g: 1,2,3,6
If you have multiple statements in your procedure you need to wrap them in a begin..end you might also be not setting delimiters. Try this
DROP PROCEDURE IF EXISTS changestatut;
DELIMITER $$
CREATE PROCEDURE changestatut(IN pstatut VARCHAR(10), IN pidpost VARCHAR(255))
COMMENT 'This procedure change the statut of activities.' NOT DETERMINISTIC NO SQL SQL SECURITY DEFINER
BEGIN
SET #req := concat('UPDATE compte set statut=\'', pstatut ,'\' where idpost in (', pidpost ,')');
PREPARE udpatestatut FROM #req; EXECUTE updatestatut;
DEALLOCATE PREPARE updatestatut;
END $$
DELIMITER ;
For some strange reason, inserting from stored procedure is not working.
This is what Im trying to do:
DROP TABLE IF EXISTS test;
CREATE TABLE IF NOT EXISTS test(
id INT(9) NOT NULL AUTO_INCREMENT
,name VARCHAR(30) NOT NULL
,PRIMARY KEY (id)
) DEFAULT CHARSET=utf8;
insert into test (name) values('A');
Inserting from command line works with no problems.
Then I created a stored procedure to do the same kind of insert:
DROP PROCEDURE IF EXISTS storedtest;
DELIMITER $$
CREATE PROCEDURE storedtest()
BEGIN
declare insert_sql varchar(200);
SET insert_sql = 'insert into test (name) values(3)';
SELECT insert_sql;
PREPARE mystm FROM #insert_sql;
EXECUTE mystm;
END$$
DELIMITER ;
call storedtest();
This gives me the error:
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'NULL' at line 1
NULL? Where did NULL came from?
I also tried changing the sql-insert to look like this (dont know if it is a good way):
SET insert_sql = "insert into test (name) values('3')";
But mysql gives me exactly the same error.
Anyone has a clue?
The NULL MySQL is reporting is an empty user variable #insert_sql, which is different from the local stored procedure local variable insert_sql which you allocated with DECLARE.
MySQL's DECLARE is used for variables local to a stored program, but according to the documentation, PREPARE stmt FROM ... expects either a string literal or a user variable, which are the type preceded with #.
PREPARE stmt_name FROM preparable_stmt
preparable_stmt is either a string literal or a user variable that contains the text of the SQL statement.
You can allocate the untyped user variable with SET so there is no need for DECLARE. You may wish to set it to NULL when you're finished.
DROP PROCEDURE IF EXISTS storedtest;
DELIMITER $$
CREATE PROCEDURE storedtest()
BEGIN
-- Just SET the user variable
SET #insert_sql = 'insert into test (name) VALUES (3)';
SELECT #insert_sql;
-- Prepare & execute
PREPARE mystm FROM #insert_sql;
EXECUTE mystm;
-- Deallocate the statement and set the var to NULL
DEALLOCATE PREPARE mystm;
SET #insert_sql = NULL;
END$$
DELIMITER ;
I'm wrestling with MySQL stored procedures, and the PREPARE / EXECUTE statement pair. I'm attempting to run the (simplified) code below in order to create a stored procedure that will encapsulate several queries into a transaction with rollback. I continue to get
Error Code: 1064
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 'goodID;
If I remove the transaction and handlers all is well with the code. If I remove the EXECUTEstatement the procedure can be created.
What am I missing here?
DELIMITER $$
USE `casc`$$
DROP PROCEDURE IF EXISTS `sp_T_MergeMemberIDs`$$
CREATE DEFINER=`root`#`localhost` PROCEDURE `sp_T_MergeMemberIDs`(IN goodID VARCHAR(8), OUT param_sp_success TINYINT)
BEGIN
DECLARE EXIT HANDLER FOR SQLEXCEPTION ROLLBACK;
DECLARE EXIT HANDLER FOR SQLWARNING ROLLBACK;
START TRANSACTION;
SET param_sp_success = 0;
SET #SQL=
"SELECT * FROM member
WHERE memberID = ?";
PREPARE stmt FROM #SQL;
EXECUTE stmt USING goodID;
-- queries executed here using the same parameter
-- omitted for simplicity
SET param_sp_success = 1;
COMMIT;
END$$
As far as I remember, you need to use session user variable in execute ...using :
...
PREPARE stmt FROM #SQL;
SET #tmp_var = goodID;
EXECUTE stmt USING #tmp_var;
...
