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 creating procedure getting error I cannot figure out why

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

all of the above tables I used exist in my database.
Thankful for any help!

MySQL Stored Procedure Case Statement Syntax Error - Contd

The Procedure contains syntax error. Please help me in finding the error. The mySQL Workbench says that this has 8 errors and this cannot be applied to the database. I have already posted this question. People told me to change the CASE statement to IF.Even after changes, the error persists. I don't know how to nest this post under the original question. The actual post was posted in this link.
Revised syntax is posted as requested #Caius Jard

You need to quote identifiers that starts with a digit:
INSERT INTO Amount(Cust_id,Book_id,Can,`300ml`,`500ml`,`1lit`,`2lit`) ...

ERROR 1064 (42000): check the manual that corresponds to your MySQL server version for the right syntax to use near 'END'

here is mycode
i am trying to create a trigger after insert on a table say product table to a change traker table called audit table
like this
DELIMITER //
CREATE TRIGGER product_table_after_insert
AFTER INSERT
ON product_table FOR EACH ROW
BEGIN
DECLARE l_product_description varchar(500);
DECLARE l_product_number int;
set #l_table_name = 'product_table';
set #l_action = 'INSERT';
set #l_table_column = 'all columns';
set #l_description = 'new row inserted';
select p.product_description ,p.product_number into #l_product_description, #l_product_number from product_table p where p.product_description = (select max(pg.product_number)from product_table pg);
-- Insert record into audit table
INSERT INTO audit_table_test
( table_name,
changed_row_id,
action,
table_column,
change_desciption,
change_time
)
VALUES
( l_table_name,
l_product_number,
l_action,
l_table_column,
l_description,
SYSDATE()
)
END
//
DELIMITER ;
this is the error i am getting
i tried all these ways
used | ,S etc instead of // and
removed ; after end, placed // or \ or $$ together and below end
nothing works, some one please help me
ERROR 1064 (42000): 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 'END' at line 32
some one please help me

Place sql terminator ";" after create table statement
remove ";" after end delimeter.
So your code should be as per below,
DELIMITER //
CREATE TRIGGER product_table_after_insert
AFTER INSERT
ON product_table FOR EACH ROW
BEGIN
DECLARE l_product_description varchar(500);
DECLARE l_product_number int;
set #l_table_name = 'product_table';
set #l_action = 'INSERT';
set #l_table_column = 'all columns';
set #l_description = 'new row inserted';
select p.product_description ,p.product_number into #l_product_description, #l_product_number from product_table p where p.product_description = (select max(pg.product_number)from product_table pg);
-- Insert record into audit table
INSERT INTO audit_table_test
( table_name,
changed_row_id,
action,
table_column,
change_desciption,
change_time
)
VALUES
( l_table_name,
l_product_number,
l_action,
l_table_column,
l_description,
SYSDATE()
);
END
//
DELIMITER

The solution provided by #juergen in comments is working fine, that is, Add a ; after the insert statement (before the END) Thanks for finding my mistake. I was looking for it for about 4 hours so Answer is here:
DELIMITER //
CREATE TRIGGER product_table_after_insert
AFTER INSERT
ON product_table
FOR EACH ROW
BEGIN
DECLARE l_product_description varchar(500);
DECLARE l_product_number int;
set #l_table_name = 'product_table';
set #l_action = 'INSERT';
set #l_table_column = 'all columns';
set #l_description = 'new row inserted';
select p.product_description ,p.product_number
into #l_product_description, #l_product_number
from product_table p
where p.product_description =
(select max(pg.product_number)
from product_table pg);
-- Insert record into audit table
INSERT INTO audit_table_test
( table_name,
changed_row_id,
action,
table_column,
change_desciption,
change_time
)
VALUES
( l_table_name,
l_product_number,
l_action,
l_table_column,
l_description,
SYSDATE()
); //<<---- Semicolon needed to be here
END
//
DELIMITER;

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)

You have to add parantheses () around the query.
