I have stored procedure. How I can call this procedure taking data from different table. idGroup is column name from different table.
DROP PROCEDURE IF EXISTS `simpleproc`;
DELIMITER ;;
CREATE DEFINER=`sa`#`192.168.1.253` PROCEDURE `simpleproc`(IN idGroup INT, IN groupName varchar(20),IN beginDate date, IN weekday1 INT, IN weekday2 INT, IN lessonCount INT)
BEGIN
DECLARE i int;
DECLARE name1 int;
DECLARE price int;
SET i:=1;
WHILE i<=lessonCount DO
SET beginDate:=DATE_ADD(beginDate,INTERVAL 1 DAY);
IF WEEKDAY(beginDate) in(weekday1,weekday2) THEN
SET name1:=groupName+i;
SET price:=price DIV 8;
insert into lessons (lessonName, idGroup, lessonPrice, datePassed)
values (name1,idGroup,price,begindate);
END IF;
SET i:=i+1;
END WHILE;
END
;;
DELIMITER ;

The following code is working properly. But when i am enabling the commented area (cursor), then the code showing error. Please help to fix the issue.
Scenario: The code allow some parameter. It will prepare the data in a table and then the cursor will take data from that table and output that data.
Same Parameter: call prGetInsuranceData_Multiple(2, 'Saroar,Ahmed', '20,30')

You need to pout the loop and its declarations in a BEGIn ENd
Still i needed to reprogram the hole thing, because your code threw error, that i couldn't find
create procedure prGetInsuranceData_Multiple(
IN PeopleToBeCovered INT,
IN _NAME VARCHAR(4000),
IN _AGE VARCHAR(200))
begin
DECLARE V_Name VARCHAR(255);
DECLARE V_AGE INT;
DECLARE X INT DEFAULT 0;
drop temporary table if exists TempCustomer;
drop temporary table if exists TempCustomer1;
create temporary table TempCustomer( NAME VARCHAR(255),AGE int );
create temporary table TempCustomer1(NAME VARCHAR(255),AGE int);
SET X = 1;
BEGIN
WHILE X <= PeopleToBeCovered DO
SET V_Name = SUBSTRING_INDEX(SUBSTRING_INDEX(_NAME,',',X),',',-1);
SET V_Age = SUBSTRING_INDEX(SUBSTRING_INDEX(_AGE,',',X),',',-1);
SET X = X + 1;
INSERT INTO TempCustomer VALUES(V_Name,V_Age);
END WHILE;
END;
BEGIN
DECLARE finished INTEGER DEFAULT 0;
DECLARE v_id int ;
DECLARE v_name varchar(255);
declare cur_NameWithAge cursor for select NAME,AGE from TempCustomer;
DECLARE CONTINUE HANDLER
FOR NOT FOUND SET finished = 1;
open cur_NameWithAge;
GetNameWithAge: LOOP
fetch cur_NameWithAge into v_name,v_id;
IF finished = 1 THEN
LEAVE GetNameWithAge;
END IF;
INSERT INTO TempCustomer1 VALUES (v_name,v_id);
END LOOP GetNameWithAge;
CLOSE cur_NameWithAge;
END;
select * FROM TempCustomer;
DROP TEMPORARY TABLE TempCustomer1;
DROP TEMPORARY TABLE TempCustomer1;

call prGetInsuranceData_Multiple(2, 'Saroar,Ahmed', '20,30')

I have 3 tables called tipo_produto & tipo_veiculo and tipo_produto_veiculo
Basicaly, a procedure called addTipo_produto that inserts values into tipo_produto and then selects tipo_produto to get the last ID where the values match but it returns null and it's impossible because I just added the value before
DELIMITER //
Create procedure addTipo_produto(
IN p_tipo_produto varchar(50),
IN p_tipo_veiculo varchar(50)
)
begin
DECLARE id_tipo_veiculo INT;
DECLARE id_tipo_produto INT;
INSERT INTO `tipo_produto`(`tipo_produto`) VALUES(p_tipo_produto);
SELECT `id_tipo_veiculo` INTO id_tipo_veiculo FROM `tipo_veiculo` WHERE `tipo_veiculo` LIKE p_tipo_veiculo;
SELECT `id_tipo_produto` INTO id_tipo_produto FROM `tipo_produto` WHERE `tipo_produto` LIKE p_tipo_produto;
INSERT INTO `tipo_produto_veiculo`(`id_tipo_produto`, `id_tipo_veiculo`) VALUES((SELECT(id_tipo_produto)), (SELECT(id_tipo_veiculo)));

Thanks everyone
I have altered one line because only insert statement was for tipo_produto table.
Hope rest can be done by you.

I've created this trigger, but I have two problems. One it does not actively populate the Person table and two. If I enter more than one row into my Party table I get an error in access, Result of Subquery returns more than one row.
Anybody know my problem(s)?
DELIMITER $$
Create TRIGGER Trigger1
AFTER
INSERT
ON Party
FOR EACH ROW
BEGIN
declare partytypeid int;
declare partyid int;
set #partyid:= (select partyid from party);
set #partytypeid:= (select partytypeid from party);
IF partytypeid = 1
THEN INSERT INTO Person
(PartyId) VALUES (PartyId);
END IF;
END$$

When you set your variables, you're doing a select against the whole table instead of the inserted record.
DELIMITER $$
Create TRIGGER Trigger1

declare partytypeid int;
declare partyid int;
set #partyid:= new.partyid;

I have table group with begindate lesson count and weekdays columns. I would like write MySQL procedure for adding data to another table named lessons according to group. But I couldn't handle with syntax of MySQL. Could you please help me resolve problems with that procedure:
CREATE PROCEDURE simpleproc (IN idGroup INT, IN groupName varchar(20),IN beginDate date, IN weekday1 INT, IN weekday2 INT, IN lessonCount INT)
BEGIN
DECLARE i;
SET i:=1;
WHILE i<=lessonCount DO
DATE_ADD(beginDate,INTERVAL 1 DAY)
IF (WEEKDAY(beginDate)=weekday1) OR (WEEKDAY(beginDate)=weekday2) THEN
SET name:=groupName+i;
SET price:=DIV(price,8)
insert into lessons (lessonName, idGroup, lessonPrice, datePassed)
values (name,idGroup,price,begindate);
SET i:=i+1
END IF;
END WHILE;
END
After solving problems I will add this code to prepared statement in Java
This will run. Make sure: 1. That you increment i in a proper place of your code inside the while loop. 2. Avoid usind reserved words (like name) for fields and variables. 3. Define price variable somewhere before making integer division of it. You know the code and your tables' structure. Nobody is capable to do it for you.
DROP PROCEDURE IF EXISTS `simpleproc`;
DELIMITER ;;
CREATE DEFINER=`root`#`localhost` PROCEDURE `simpleproc`(IN idGroup INT, IN groupName varchar(20),IN beginDate date, IN weekday1 INT, IN weekday2 INT, IN lessonCount INT)

SET name1:=groupName+i;
SET price:=price DIV 8;
insert into lessons (lessonName, idGroup, lessonPrice, datePassed)

I have a little problem. Looks like the procedure does not exist. Somehow it's dropped after the creation. I get different error each time i change something. I'm not really sure what's causing the error, maybe I'm not allowed to drop procedures and creating them in the same query.
I hope you guys can help me out.
drop procedure if exists refIntChk;
DELIMITER //
CREATE PROCEDURE refIntChk(IN district INT(11), OUT b INT(1))
BEGIN
DECLARE b INT(1);
IF district IN (select dist FROM t13)
THEN
SET b = 1;
ELSE
SET b = 0;
END IF;
END; //
DELIMITER ;
drop procedure gen if exists ;
DELIMITER //
CREATE PROCEDURE gen()
BEGIN
DECLARE rows INT(11) DEFAULT (SELECT COUNT(dist) FROM t13);
DECLARE district INT(11);
DECLARE custname VARCHAR(16);
DECLARE revenue FLOAT;
DECLARE x INT DEFAULT 10000;
DECLARE outvar INT(11);
WHILE x > 0
DO
SET district = FLOOR(RAND()*rows)+1;
CALL refIntChk(district, outvar);
IF outvar = 1
THEN
SET custname = substring(MD5(RAND()), -16);
SET revenue = (RAND() * 10);
INSERT INTO t14 VALUES(NULL, custname, district, revenue);
SET x = x - 1;
END IF;
END WHILE;
END;//
DELIMITER ;
CALL gen();
When you get errors, it's usually good to run each statement, one by one, and see which one is producing the error.
The second DROP procedure statement should be:
drop procedure if exists gen;
