call simple database procedure using Slick 3.0 - mysql

Question

I have written a simple database procedure in mySQL as follows:
DROP PROCEDURE IF EXISTS sp_doSomething;
DELIMITER //
CREATE PROCEDURE sp_doSomething
(IN pVal1 varchar(100),
IN pVal2 int(15)
)
BEGIN
DECLARE vCnt int(5) DEFAULT 0;
DECLARE vID int(15) DEFAULT 0;
DECLARE vTempID int(15) DEFAULT 0;
-- get ID
SELECT id INTO vID FROM T1
WHERE name = pVal1;
-- get count
SELECT count(*) INTO vCnt FROM T1
WHERE owner = vID;
-- get the log
INSERT INTO log select CONCAT('-v1-:', pVal1, ':-v2-:', pVal2);
-- Create basic stuff if it doesn't exist
IF vFolderCnt = 0 THEN
INSERT INTO T1 (`id`, `col1`, `col2`, `col3`)
SELECT null, vID, 'some value', CONCAT(vID,'^1') FROM T1
WHERE owner = 0;
END IF;
commit;
END //
DELIMITER ;
Now, I want to call this procedure in my Play Framework 2.4 application which uses Slick 3.0. It is such a simple thing but I am really struggling with it as there is no proper documentation available. It's very frustrating.
As it's mentioned on Google Group here https://groups.google.com/forum/#!searchin/scalaquery/procedure/scalaquery/BUB2-ryR0bY/EFZGX663tRYJ
I tried calling the procedure by different way. The code compiles but the procedure does not get called at all.
This statement gives an action error.
db.run(sql"{call sp_doSomething('${st.val1}', 1)}")
The following statement compiles fine but does not invoke the procedure.
db.run(sql"{call sp_doSomething('${st.val1}', 1)}".as[Int])
The following statement compiles fine but does not invoke the procedure.
db.run(sqlu"{call sp_doSomething('${st.val1}', 1)}")
Or
db.run(sqlu"{?=call sp_doSomething('${st.val1}', 1)}")
I have granted the Execute permission on the procedure to my DB user and verified it.
Also, I am not sure, whether the COMMIT is required in the procedure or not?
Any help, will be highly appreciated.

Answer 1

I have managed to invoke the stored procedure using old prepareCall method. Here's how I have done it. Hope, it might help someone.
db.withSession {
implicit session => {
val cs = session.conn.prepareCall("{call sp_doSomething(?, ?)}")
cs.setString(1, st.val1)
cs.setLong(2, 1L)
val result = cs.executeUpdate()
}
}
But I would be still interested in invoking the procedure using sql"" or sqlu"".

For me the following works in Slick 3.2:
delimiter //
create procedure Try1()
begin
select userid from TBL_USER where id = "4";
end //
delimiter ;
Then
def runProcByRawSql() : Future[Vector[String]] = {
def runproc = sql"""call Try1()""".as[String]
db.run(runproc)
}
