I cannot work out what I am doing wrong. My tables has 1262717 rows.
I have this SQL:
SELECT count(hud_case_number) FROM suitecrm.ht_homes where hud_case_number = "abc"
Which correctly replies with 0
When I convert it to a stored procedure:
CREATE DEFINER=`root`#`%` PROCEDURE `hud_does_property_exist`(IN hud_case_number varchar(20))
BEGIN
SELECT count(hud_case_number) FROM suitecrm.ht_homes where hud_case_number = hud_case_number;
END
and call it like this:
Call hud_does_property_exist('abc')
It returns the answer 1262717
I just cannot see what I am doing wrong. I suspect it's something to do with the hud_case_number parameter?
Try This :-
CREATE DEFINER=`root`#`%` PROCEDURE `hud_does_property_exist`(IN
in_hud_case_number varchar(20))
BEGIN
SELECT count(hud_case_number) FROM suitecrm.ht_homes where hud_case_number =
in_hud_case_number;
END

I'm trying to create a stored procedure that calculates total revenue from a customer by if it's occupied and the standard rate. I am getting an error message and when I try to call from it I get NULL. Can anyone help? Thanks.
//Delimiter
CREATE PROCEDURE calculateRevenue (in customerIDs int, OUT totalRevenue dec(15,2))
BEGIN
SELECT SUM(Occupied*StandardRate) into totalRevenue FROM climatesouth
WHERE customerIDs = customerID;
END //
delimiter//
call calculateTotal(10, #totalRevenue);
SELECT #totalRevenue;
First you need to give your input parameters different names from the columns. Then you need to use them. Also, DELIMITER goes before the stored procedure definition:
DELIMITER //
CREATE PROCEDURE calculateRevenue (
in in_customerIDs int,
out out_totalRevenue dec(15,2))
BEGIN
SELECT SUM(cs.Occupied cs.* cs.StandardRate) into out_totalRevenue
FROM climatesouth cs
WHERE cs.customerID = in_customerID;
END //
The delimiter assignment is off: your are setting it to // after the create procedure statement.
Also, the parameter name needs to be fixed: your are not using the correct name in the query (your parameter has a trailing 's'), because of which the procedure will not produce the result you expect.
So:
delimiter // -- change the default delimiter here
create procedure calculaterevenue (in p_customerid int, out p_totalrevenue dec(15,2))
begin
select sum(occupied * standardrate) into p_totalrevenue
from climatesouth
where customerid = p_customerid; -- "p_customerid" is the parameter name
end //
delimiter ; -- reset the delimiter, now we can call the procedure
call calculaterevenue(10, #totalrevenue);
select #totalrevenue;
It is easier just to return the result as a result set rather than to use the OUT-parameter. The OUT-parameters are usually used only when calling procedure from another procedure. If you call the procedure from your application, use the result set.
delimiter //
CREATE PROCEDURE calculateRevenue (in_customerID int)
BEGIN
SELECT SUM(Occupied*StandardRate) as totalrevenue
FROM climatesouth
WHERE customerID = in_customerID;
END
//
delimiter ;
call calculateRevenue(10);
I'm trying to call a stored procedure from another stored procedure and store the value in a variable. The inner stored procedure basically checks if something exists and uses a select statement to return a zero or one. I keep getting an error. In this situation, MySQL is saying "=" is not valid at this position, expecting ";"
CREATE PROCEDURE `CardNames_Add` (searchedCard VARCHAR(50))
BEGIN
DECLARE exist TINYINT;
EXECUTE exist = CardNames_CheckExist searchedCard
IF (exist = 0)
INSERT INTO card_names (name)
VALUE(searchedCard)
END
You have to rewrite you other stored procedure, that you don't need btw, to give back a result
CREATE PROCEDURE CardNames_CheckExist (IN searchedCard VARCHAR(50), OUT result TINYINT )
BEGIN
--do some stuzff
result = 1
END
CREATE PROCEDURE `CardNames_Add` (searchedCard VARCHAR(50))
BEGIN
CALL CardNames_CheckExist(searchedCard,#result);
IF (#result = 0) THEN
INSERT INTO card_names (name)
VALUES (searchedCard);
END IF;
END
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//
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 just starting to learn how to write stored procedures in MYSQL and I've hit a roadblock.
I wrote the following code:
DELIMITER $$
DROP PROCEDURE IF EXISTS `emscribedx`.`countcodes` $$
CREATE PROCEDURE `emscribedx`.`countcodes` ()
BEGIN
declare doneprocessing int default 0;
declare thisaccount varchar(50);
declare countcursor cursor for select acct from patientid where patienttype='P';
declare continue handler for not found
set doneprocessing = 1;
Fetch countcursor into thisaccount;
Repeat
select * from doc_table where acct = thisaccount;
until doneprocessing = 1
END repeat;
close countcursor;
END $$
DELIMITER ;
I would like to display the results of the select statement that occurs after the repeat statement. But how do I do that? When I execute the stored procedure, nothing happens?
Thank you,
Elliott
The procedure can only return the results of a single query, why not use this instead?
SELECT doc_table.*
FROM doc_table
INNER JOIN patientid
ON patientid.acct = doc_tableacct
WHERE patientid.patienttype='P';
It can be put inside of a procedure if you want.
