Mysql loop and insert - mysql

Question

I have the following MySql script:
SET #skip = 0;
SET #max = (SELECT COUNT(*) FROM table1);
CREATE TEMPORARY TABLE TempTable(
id INT NOT NULL,
name VARCHAR(32) NOT NULL
);
loop1: LOOP
INSERT INTO TempTable (id, name) SELECT id, name FROM table1 LIMIT #skip, 1;
IF #skip < #max THEN
SET #skip = #skip + 1;
ITERATE loop1;
END IF;
LEAVE loop1;
END LOOP loop1;
SELECT * FROM TempTable;
This script is not working but it should select all the id and names in table1. I am using a loop because I am also going to do other stuff in those loops but that is for later.
I am not looking for a solution like SELECT id, name FROM table1 but I want my error fixed. So I can continue with my loop.
The error I get is:
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 'loop1: LOOP INSERT INTO TempTable (id, name) SELECT id, name
FROM table1' at line 1

Answer 1

/* set delimiter */
DELIMITER $$
/* remove procedure if exists... */
DROP PROCEDURE IF EXISTS insert_it $$
/* create procedure */
CREATE PROCEDURE insert_it ()
BEGIN
DECLARE varcount INT DEFAULT 1;
DECLARE varmax INT DEFAULT 15;
WHILE varcount <= varmax DO
INSERT INTO yourtable(fixed_val, count_val) VALUES(3493, varcount);
SET varcount = varcount + 1;
END WHILE;
END $$
/* reset delimiter back to normal */
DELIMITER ;
/* call procedure */
CALL insert_it();

Answer 2

try something like this for the syntax of your loop:
DECLARE #count INT;
DECLARE #max INT;
SET #count=1;
SET #max= (SELECT COUNT(*) FROM table1);
WHILE(#count < #max)
BEGIN
/*your database query logic*/
END
use "SET #count=(#count+1)" to increment your counter within the loop

Answer 3

There is a syntax error in your code (the LIMIT #skip which is dynamic SQL and requires some tricks to make it work) but it is not at loop1: LOOP.
My guess is you are trying to use LOOP outside a compound statement (BEGIN ... END) like a stored procedure, which is not possible. You have to create a stored procedure to do that.
