MySQL creating procedure getting error I cannot figure out why - mysql

I want to create a procedure for a MySql database but I get this error below and after 2h of research I still cannot figure out why.
The code is the following :
delimiter //
create procedure mitarbeiter_projekt (proj_name varchar(20), mitarb_name varchar(20))
begin
declare pruef_id int;
declare new_id int;
declare mitarb_id int;
select count(id) from t_proj where name = proj_name into pruef_id;
select id from t_ma_dt where name = mitarb_name into mitarb_id;
if pruef_id = 0 then
select max(id) + 1 from t_proj into new_id;
insert into t_proj (id, name) values (new_id, proj_name);
insert into t_ma_proj (ma_id, proj_id )values (mitarb_id, new_id);
else
select id from t_proj where name = proj_name into new_id;
insert into t_ma_proj (ma_id, proj_id) values (mitarb_id, new_id);
end //
"ERROR 1064 (42000): You have an error in your SQL syntax; check the
manual that corresponds to your MariaDB server version for the right
syntax to use near '' at line 15"
all of the above tables I used exist in my database.
Thankful for any help!

The following is the procedure.

END

The script applied successfully even if it showed error. The Back Tick to column names starting with digits solved the issue. Upon Refreshing, it got changed from _SYNTAX_ERROR to its actual name.

mysql stored procedure declare error

I don't really get the error ...
i put the declare statement right after begin. i usually do a lot of MS SQL so i am not that practiced in mysql syntax. please help me out
DELIMITER //
CREATE DEFINER=`root`#`localhost` PROCEDURE `AddEntry2`(IN `inDate` DATE, IN `inUser` INT, IN `inComment` TEXT, IN `inStart` INT, IN `inEnd` INT)
BEGIN
DECLARE commID UNSIGNED;
INSERT IGNORE INTO dimcomment (comment) values (inComment);
SELECT commID := MAX(id)
FROM dimcomment
WHERE comment = inComment;
INSERT INTO factentry (FKDate, FKUser, FKComment,FKStart,FKEnd,FKAbsence)
VALUES (
inDate,
inUser,
commID,
inStart,
inEnd,
1
);
END //
Error I get:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'UNSIGNED;
INSERT IGNORE INTO dimcomment (comment) values (inComment);
SELECT c' at line 3
well i changed UNSIGNED to INT and Error Message changed:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ':= MAX(id)
FROM dimcomment
' at line 5
Seems like i cannot set via SELECT VAR := VALUE ?

Issue with stored procedure and COUNT IF statement

So I need to make a stored procedure called AddComment, that will add a comment to my Comments table , then add an entry into the Commenters table if that commenters name does not exist.
DELIMITER //
CREATE PROCEDURE AddComment(Name VARCHAR(60), Title VARCHAR(60), Comments VARCHAR(60))
BEGIN
INSERT INTO Comments(Name, Title, Comments)
VALUES (Name, Title, Comments);
DECLARE name_count INT;
SELECT COUNT(Name) INTO name_count
FROM Commenters
WHERE Name = Name;
IF name_count = 0
THEN INSERT INTO Commenters(Name)
VAlUES(Name);
ELSEIF name_count = 1
THEN INSERT IGNORE Commenters(Name)
VALUES(Name);
END IF;
END;
//
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version fo
r the right syntax to use near 'DECLARE name_count INT;
SELECT COUNT(Name) INTO name_count
FROM Commenters
^ Is the error I'm getting. I keep tweaking my code trying to figure it out, but nothing is working.

You need a cursor to use syntax like that, but you can use SET:
SET name_count = (SELECT COUNT(*) ...);
Or better yet, since you don't actually use the value, eliminate the variable entirely:
IF NOT EXISTS (SELECT * FROM ...) THEN

SQL If Statment / select into in a stored procedure

I cannot understand why the following SQL procedure will not store on my database and is reporting an error, I've been at it for ages and am totally puzzled.
DELIMITER $$
CREATE PROCEDURE add_brand(IN inBrandName TEXT)
BEGIN
DECLARE brandexists INT DEFAULT 0;
SELECT count(*) WHERE BrandName = inBrandName INTO brandexists;
IF brandexists = 1 THEN
select "exists";
ELSE
INSERT INTO tblBrand (BrandName) VALUES (inBrandName);
SELECT LAST_INSERT_ID();
END IF;
END
The error i'm getting is this:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE BrandName = inBrandName INTO brandexists; IF brandexists = 1 THEN sele' at line 6
any ideas?

You are missing a table where you select from:
SELECT count(*) WHERE BrandName = inBrandName INTO brandexists;
^---here (from some_table)

Mysql stored procedure syntax

I am trying to write simple mysql stored procedure and it seems that I can't get it right, so far I have
delimiter //
create procedure addRecord(_login varchar(15),_artist varchar(50),_record varchar(50))
begin
declare dbArtist varchar(50);
delcare dbRecord varchar(50);
set dbArtist = (select artistname from artists where lower(artistname) = lower(_artist));
set dbRecord=(select recordname from records where lower(recordname)=lower(_record));
if not exists (select * from Artists where lower(artistname)=lower(_artist)) then
begin
INSERT INTO `Artists`(`ArtistName`) VALUES (_artist);
set dbArtist=_artist;
end
if not exists (select * from Records as R inner join Artists as A on R.ArtistId=A.ArtistId where lower(R.RecordName)=lower(_record) and A.ArtistName=dbArtist) then
begin
INSERT INTO `Records`(`ArtistId`, `RecordName`) VALUES ((select artistid from artists where artistname=dbArtist),_record);
set dbRecord=_record;
end
end
but I get syntax error in line 4:
#1064 - You have an error in your SQL syntax; check the manual that corresponds
to your MySQL server version for the right syntax to use near 'dbRecord varchar(50);
set dbArtist = (select artistname from artists where lowe' at line 4
this message error was returned to me by phpMyAdmin, can anyone tell me why do I get an error?
edit: modified version, still not good
delimiter //
create procedure addRecord(_login varchar(15),_artist varchar(50),_record varchar(50))
begin
declare dbArtist varchar(50);
declare dbRecord varchar(50);
set dbArtist = (select artistname from artists where lower(artistname) = lower(_artist));
set dbRecord=(select recordname from records where lower(recordname)=lower(_record));
if not exists (select * from Artists where lower(artistname)=lower(_artist)) then
begin
INSERT INTO `Artists`(`ArtistName`) VALUES (_artist);
set dbArtist=_artist;
end
if not exists
(select * from Records as R inner join Artists as A on R.ArtistId = A.ArtistId where lower(R.RecordName)=lower(_record) and A.ArtistName=dbArtist)
then
begin
INSERT INTO `Records`(`ArtistId`, `RecordName`) VALUES ( (select artistid from artists where artistname=dbArtist) ,_record);
set dbRecord=_record;
end
end
now error in line 14 and message:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'if not exists (select * from Records as R inner join Artists as A on R.ArtistId' at line 14

The problem is that you misspelled DECLARE:
delcare dbRecord varchar(50);
UPDATE: For your next error, the problem is your illegal use of NOT EXISTS.
Within a stored procedure the proper approach is to count the existing rows, and then conditionally insert a value if the count is 0.
Something like this:
SELECT COUNT(*)
INTO #v_row_count
FROM Artists
WHERE LOWER(artistname)=LOWER(_artist);
IF (#v_row_count = 0)
THEN
INSERT INTO `Artists`(`ArtistName`) VALUES (_artist);
set dbArtist=_artist;
END IF;
P.S. To avoid poor performance on on your select query, you should consider using a collation that is not case-sensitive so you don't need to apply the LOWER() function to the artistname column.
