I m passing parameters in stored procedures but unable to fetch records when filtering with inputs.But when I store that Input into variables and pass it to fetch record I get the records.why?
Here is stored procedure
DELIMITER $$
DROP PROCEDURE IF EXISTS Demo_akg$$
CREATE PROCEDURE Demo_akg (IN ip_Id VARCHAR (100))
BEGIN
SELECT * FROM table_namel IAS WHERE Id = ip_Id;
END$$
DELIMITER;
I tried to take input in variable and pass it to where clause ti fetch records .
Here is the method that I have tried. And it works why?
DELIMITER $$
DROP PROCEDURE IF EXISTS Demo_akg$$
CREATE PROCEDURE Demo_akg (IN ip_Id VARCHAR (100))
BEGIN
Select ip_Id into #ip_Id;
SELECT * FROM table_namel IAS WHERE Id = #ip_Id;
END$$
DELIMITER;
We didn't know the structure of table_namel, but it seems the table have a field with same name as input parameter.
To prevent that use the parameters with some prefix/surfix:
DELIMITER $$
DROP PROCEDURE IF EXISTS Demo_akg$$
CREATE PROCEDURE Demo_akg (IN p_ip_Id VARCHAR (100))
BEGIN
SELECT * FROM table_namel IAS WHERE Id = p_ip_Id;
END$$
DELIMITER;

How to pass a list of IDs to MySQL stored procedure?
(1 answer)
Closed 4 years ago.
I have a MySQL statement as below:
select * from jobs where job_status in (6,9,10) and due_date>'2018-10-31'
I would like to create a store procedure, so that it takes 2 parameters:
job_status
and
due_date
I am not sure how to define the "job_status" parameter. It is a list of integers and can be any number of values. e.g. (1,2,3,4,5) or (1)
You can try by declaring variable like below
DECLARE #LIST VARCHAR(200)
DECLARE #vdate date
SET #LIST = '1,3'
SET #vdate='2018-10-31'
select * from jobs where job_status in (#LIST) and due_date>#vdate
DELIMITER $$
DROP PROCEDURE IF EXISTS `sp_selectjobs` $$
CREATE DEFINER=`root`#`%` PROCEDURE `sp_selectjobs`(
IN job_status_in VARCHAR(255),
IN due_date_in datetime )
BEGIN
SELECT * FROM jobs
WHERE job_status in (#job_status_in) AND due_date>'#due_date_in'
END $$
DELIMITER ;
you can create stored procedure like this and you can call this stored procedure with your own parameters like
call sp sp_selectjobs('1,2,3,4','2018-11-2')
like this
In Mysql you have to create store procedure such as:
DELIMITER //
DROP PROCEDURE IF EXISTS up_getJobsByStatusAndDuedate //
CREATE PROCEDURE `up_getJobsByStatusAndDuedate`(pJobStatusList TEXT, pDuedate varchar(10))
BEGIN
select * from jobs where job_status in (pJobStatusList) and due_date> pDuedate;
END//
Then you can test call store on Workbench:
call up_getJobsByStatusAndDuedate('6,9,10', '2018-10-31');
I have the following table created in mysql database.
create table stud_info(Student_ID int,Name varchar(10),Class varchar(10),Marks int)
I have also created a stored procedure to retrieve the name given the id like below:
DELIMITER //
create procedure selectEmp2(IN num1 INT,OUT name varchar(20))
BEGIN
select Name INTO name from myDB.stud_info where Student_ID=num1;
END//
When I am calling the stored procedure , I am getting null value. Please let me know where I am going wrong.
I think your stored procedure should work, but I would advise giving names to parameters that are likely to be unique. I also prefer explicit variable assignment, because select into can mean different things. Does this work?
DELIMITER //
create procedure selectEmp2(IN in_num1 INT, OUT out_name varchar(20))
BEGIN
select si.Name into out_name
from myDB.stud_info si
where si.Student_ID = in_num1;
END;//
Try this:
DELIMITER //
create procedure selectEmp2(IN _num1 INT,OUT _name varchar(20))
BEGIN
select Name INTO _name
from myDB.stud_info
where Student_ID=_num1;
END//
DELIMITER $$
DROP PROCEDURE IF EXISTS `insert_or_update`$$
CREATE PROCEDURE insert_or_update(
IN username VARCHAR(70),
IN score INT,
IN titlein VARCHAR(70)
)
begin
IF EXISTS (SELECT * FROM two_player WHERE title=titlein and user1!=username and user2='') THEN
UPDATE two_player SET score12=score , user2=username WHERE title=titlein and user1!=username and user2='' limit 1;
ELSE
INSERT INTO two_player (user1,score11,title) values (username, score, titlein);
END if;
END$$
DELIMITER ;
call insert_or_update('sara',20,'math');
I create a procedure. But when I try to call it I get this error message:
#1305 - PROCEDURE u941310304_menu.insert_or_update does not exist
What's wrong?
I tested you code and the call to procedure works.
Your default database is u941310304_menu, it seems you are creating the procedure in another db. You can create the procedure specifying the destination database.
DELIMITER $$
DROP PROCEDURE IF EXISTS `u941310304_menu`.`insert_or_update`$$
CREATE PROCEDURE `u941310304_menu`.insert_or_update(
[...]
If the procedure is in another database you must specify the db name as prefix:
call `another_database`.insert_or_update('sara',20,'math');
I have created a Stored Procedure
CREATE PROCEDURE GetAllRecords()
BEGIN
SELECT * FROM my_table;
END //
Now I want to add a parameter to this Stored Procedure like this :
CREATE PROCEDURE GetAllRecords(id1 INT(4))
BEGIN
SELECT * FROM my_table WHERE `id` = id1;
END //
How can I edit my Stored Procedure?
Delete the procedure
drop procecdure GetAllRecords//
And recreate it
CREATE PROCEDURE GetAllRecords(id1 INT(4)) ...
You have drop procedure first and then re-create it
DROP PROCEDURE IF EXISTS GetAllRecords;
CREATE PROCEDURE GetAllRecords(IN _id INT)
SELECT *
FROM my_table WHEREid = _id;
And since you're using the only statement in your procedure you can ditch BEGIN ... END block and use a usual delimiter.
In case you're wondering no you can not use ALTER PROCEDURE in this case
This statement can be used to change the characteristics of a stored
procedure. However, you cannot change the parameters or body of a
stored procedure using this statement; to make such changes, you
must drop and re-create the procedure using DROP PROCEDURE and CREATE PROCEDURE.
First of all ,This is not how you can pass the parameter in stored procedure.
You can not alter stored procedure, the way to do this is drop existing and create new one.
DELIMITER $$
DROP PROCEDURE IF EXISTS GetAllRecords$$
CREATE PROCEDURE GetAllRecords(IN param1 INT, OUT pram2 Varchar(100), INOUT param3 Date)
BEGIN
select * from <tbl>;
< Your queries>
END$$
DELIMITER ;

To Alter a stored Procedure check this link
http://technet.microsoft.com/en-us/library/ms345356.aspx
The best way is to drop the stored proceure and create it again
DROP PROCEDURE IF EXISTS GetAllRecords
CREATE PROCEDURE GetAllRecords(IN _id INT)
AS
BEGIN
SELECT *
FROM my_table WHEREid = _id;
END
I am trying to create a mysql stored procedure, but I get this error:
Script line: 2 Failed to CREATE PROCEDURE proc_test_bideep
The stored procedure code is:
DELIMITER $$
DROP PROCEDURE IF EXISTS `commun`.`insert_categorie` $$
CREATE PROCEDURE `commun`.`insert_categorie` (id_mere INT,
lib_categ VARCHAR(50),
id_categ_sup INT ,
categ_authInstantBuy INT)
BEGIN
SET #bg_mere := (SELECT categ_bg FROM categ_basic WHERE categ_id = id_mere);
#bg_mere+2,categ_level_bideep,categ_statut,categ_adult,categ_authSmallBid,categ_authBid,categ_authInstantBuy);
SELECT '1' AS code_retour; END IF;
ecetera.........
END $$
DELIMITER ;
a) You need to DECLARE any variables on the first lines of the procedure, including their datatype:
DECLARE bg_mere INT;
b) To fetch a value from the database into a variable, you use SELECT ... INTO syntax:
SELECT categ_bg INTO bg_mere FROM categ_basic WHERE categ_basic.categ_id = id_mere;
c) You have an END IF without the corresponding IF.
d) The closing END needs a semicolon (not BEGIN though), only then do you need a delimiter to finish the entire statement, and finally you should reset the delimiter back to normal:
BEGIN
# body of the stored procedure goes here
END;
$$
DELIMITER ;
Your parameters are missing the keyword IN such as: ...(IN id_mere INT, IN lib_categ ...). Also, you need to configure your OUT variable for #bg_mere in the initial parameter list such as (IN xxx, ..., OUT bg_mere VARCHAR/INT/WHATEVER).
