How to declare variables in mysql Stored procedure? - mysql

I want to declare a variable and then assign a value of select query to that particular variable and then I need to pass that variable in an insert statement . So I tried the below code,
DROP PROCEDURE IF EXISTS `pro_damagestockdao` $$
CREATE DEFINER=`root`#`localhost` PROCEDURE `pro_damagestockdao`(
IN damage_date date,
IN damage_inv_no varchar(12),
IN damage_inv_date date,
IN damage_dist_name varchar(30),
IN damage_contact_no varchar(15),
IN damage_item_code varchar(30),
IN damage_item_name varchar(30),
IN damage_batch_no varchar(15),
IN damage_mfr_name varchar(50),
IN damage_expiry_date date,
IN damage_pur_qty int(11),
IN damage_qty int(11),
IN damage_unit_price double(10,2),
IN damage_unit_vat double(4,2),
IN damage_unit_discount double(4,2),
IN damage_sub_total double(10,2),
IN damage_total_amount double(10,2),
IN damage_remarks varchar(1000),
IN functionality varchar(20),
out flag int
)
BEGIN
DECLARE selCnt int;
DECLARE dqty int;
SET dqty = (SELECT free FROM purchase_invoice p WHERE p.invoice_no = damage_inv_no);
DECLARE EXIT HANDLER FOR SQLEXCEPTION ROLLBACK;
SET flag=0;
START TRANSACTION;
if(functionality='save') then
INSERT INTO damage_stocks
(damage_stock_date,invoice_no,invoice_date,dist_name,contact_no,item_code,item_name,batch_no,qty,damaged_qty,unit_price,unit_vat,unit_discount,sub_total,total_amount,remarks) VALUES
(damage_date,damage_inv_no,damage_inv_date,damage_dist_name,damage_contact_no,0,damage_item_name,damage_batch_no,dqty,damage_qty,damage_unit_price,damage_unit_vat,damage_unit_discount,damage_sub_total,damage_total_amount,damage_remarks);
But it fails.. You see, I declared a variable dqty and then I passed it to the insert statement.


It is not problem to declaration. It is assign problem
try this query
SELECT free into dqty FROM purchase_invoice p WHERE p.invoice_no = damage_inv_no;


The following code works fine for me:
DELIMITER $$
USE `test`$$
DROP PROCEDURE IF EXISTS `pro_damagestockdao`$$
CREATE DEFINER=`root`#`localhost` PROCEDURE `pro_damagestockdao`(
IN damage_date DATE,
IN damage_inv_no VARCHAR(12),

IN damage_item_name VARCHAR(30),
IN damage_batch_no VARCHAR(15),
IN damage_mfr_name VARCHAR(50),
IN damage_expiry_date DATE,
IN damage_pur_qty INT(11),
IN damage_qty INT(11),
IN damage_unit_price DOUBLE(10,2),
IN damage_unit_vat DOUBLE(4,2),
IN damage_unit_discount DOUBLE(4,2),
IN damage_sub_total DOUBLE(10,2),
IN damage_total_amount DOUBLE(10,2),
IN damage_remarks VARCHAR(1000),
IN functionality VARCHAR(20),
OUT flag INT)
BEGIN
DECLARE selCnt INT;
DECLARE dqty INT;
DECLARE EXIT HANDLER FOR SQLEXCEPTION ROLLBACK;
SET dqty = (SELECT free FROM purchase_invoice p WHERE p.invoice_no = damage_inv_no);
SET flag = 0;
START TRANSACTION;
IF(functionality = 'save') THEN
INSERT INTO damage_stocks (damage_stock_date, invoice_no, invoice_date, dist_name, contact_no, item_code, item_name, batch_no, qty,damaged_qty, unit_price, unit_vat, unit_discount, sub_total, total_amount, remarks)
VALUES (damage_date, damage_inv_no, damage_inv_date, damage_dist_name, damage_contact_no, 0, damage_item_name, damage_batch_no, dqty,damage_qty, damage_unit_price, damage_unit_vat, damage_unit_discount, damage_sub_total, damage_total_amount, damage_remarks);
END IF;
END$$
DELIMITER ;
With this SP call:
CALL `pro_damagestockdao`("2015-06-23","rx45","2015-06-20","DistName","DContactNo","DamageItemCode","damage_item_name","damage_batch_no","damage_mfr_name", "2015-07-01", 10, 5, 15.2, 7.66, 9.88, 99.00, 150.22, "No remarks", "save", #sorin);
What error do you get?
Do you get an error when trying to create the stored procedure or when you call it?

I want to increase or decrease the amount of money in Total_Crédit which is in Credit_electrecité depending on the event to be done

create PROCEDURE PR_Credit_Total(
in newidpiece int,
in newnpiece bigint,
in newnop varchar(60),
in newdateengagement date,
in newdatefacture date,
in newlocalité varchar(50),

in newcreated varchar(25),

BEGIN
set #total=(SELECT sum(Total_Crédit) from credit_electricité) ;
if event=='ajouter'
and newtournee is null
THEN
if #total-newmontant>=0
INSERT into vignetteoneep VALUES(newidpiece,newnpiece,newnop,newdateengagement,
newdatefacture,newlocalité,newtournee,newnpolice,newservice,newmontant,newecheance,newcreated);
then
UPDATE credit_electricité set Total_Crédit=Total_Crédit-newmontant;
end if;
end if;
END

create PROCEDURE PR_Credit_Total(
#newidpiece AS int,
#newnpiece AS bigint,
#newnop AS varchar(60),
#newdateengagement AS date,
#newdatefacture AS date,
#newlocalité AS varchar(50),
#newtournee AS int,
#newnpolice AS bigint,
#newservice AS varchar(20),
#newmontant AS float,
#newecheance AS varchar(7),
#newcreated AS varchar(25),
#event AS varchar(100),
#total AS INT
)
AS
BEGIN
set #total=(SELECT sum(Total_Crédit) from credit_electricité)
if #event = 'ajouter' and #newtournee is null
if #total - #newmontant >=0
INSERT into vignetteoneep VALUES(newidpiece,newnpiece,newnop,newdateengagement,
newdatefacture,newlocalité,newtournee,newnpolice,newservice,newmontant,newecheance,newcreated)
UPDATE credit_electricité set Total_Crédit=Total_Crédit - #newmontant
END

Here's a list of syntax errors to fix
in eventvarchar(100) missing space ,should be in event varchar(100) but event is a keyword and best avoided
if event=='ajouter' null safe equal in mysql is <=> so should be if event <=> 'ajouter' but = would do
The second if does not have a then it's not clear if the insert and update should be part of same condition but I suspect not
if #total-newmontant>=0 then
INSERT ...
else
UPDATE ...
end if;
And you may need to set delimiters

And my cursor fails me because it does not return the expected result. For example DISTRIBUCIONES SUR should give me SUAVIZANTE, PALMERITA and ZANAHORIA.

I found my bug. It turns out that I had a fetch left over and that's why it cut me off and didn't give it to me correctly because it overwrote what I had before.

You must define IN for the parameters.

how to write procedure to insert data in to the table in phpmyadmin?

I have created table as below:
student:
+----+------+-----------+--------+
|uid | name | user_name | branch |
+----+------+-----------+--------+
| | | | |
+----+------+-----------+--------+
I want to insert data in to the table using procedure.
the procedure which i wrote is:
create procedure add(in_name varchar(50),in_user_name
varchar(50),in_branch varchar(50))
begin
insert into student
(name,user_name,branch) values (in_name ,in_user_name,in_branch);
end;

Try this-
CREATE PROCEDURE simpleproc (IN name varchar(50),IN user_name varchar(50),IN branch varchar(50))
BEGIN
insert into student (name,user_name,branch) values (name ,user_name,branch);
END

# Switch delimiter to //, so phpMyAdmin will not execute it line by line.
