What is the error in my mysql user defined function? - mysql

Syntax error at line 6 in mysql 8.0, The function created as below
CREATE FUNCTION getStokMiktar(p_sto_id INT, p_dep_id INT)
RETURNS DOUBLE
BEGIN
DECLARE ret DOUBLE
SET ret = (SELECT SUM(CASE WHEN sth_depoid_cikis = p_dep_id THEN -sth_miktar
WHEN sth_depoid_giris = p_dep_id THEN sth_miktar
ELSE 0
END CASE)
FROM stokhareketleri
WHERE
(sth_depoid_cikis = p_dep_id OR sth_depoid_giris = p_dep_id)
AND sth_stokid = p_sto_id)
RETURN ret
END
And my table's structure is :
CREATE TABLE `stokhareketleri` (
`sth_id` BIGINT(20) NOT NULL AUTO_INCREMENT,
`sth_stokid` INT(11) NOT NULL,
`sth_giriscikis` TINYINT(4) NOT NULL,
`sth_evraktipi` INT(11) NOT NULL,
`sth_depoid_cikis` INT(11) NOT NULL,
`sth_depoid_giris` INT(11) NOT NULL,
`sth_miktar` DOUBLE NOT NULL,
PRIMARY KEY (`sth_id`)
)
COLLATE='utf8_turkish_ci'
ENGINE=InnoDB
;
What is the error at line 6? Thanks in advance.

As mentioned by #Salmon, try this
delimiter $$
CREATE FUNCTION getStokMiktar(p_sto_id INT, p_dep_id INT)
RETURNS DOUBLE
BEGIN
DECLARE ret DOUBLE;
SELECT
SUM(CASE WHEN sth_depoid_cikis = p_dep_id THEN - sth_miktar
WHEN sth_depoid_giris = p_dep_id THEN sth_miktar
ELSE 0 END) INTO ret
FROM stokhareketleri
WHERE p_dep_id IN (sth_depoid_cikis,sth_depoid_giris)
AND sth_stokid = p_sto_id;
RETURN ret;

MySQL SELECT not finding known values

There is probably something simple here that I'm just not seeing, but I've been trying all I can think of for a few hours. It's time to toss it to more knowledgable folks...
I want to attempt to intercept a duplicate index, so my auto increment value doesn't advance. Plus, after this much time, it has just become one of those things I have to solve at this point.
Starting with an empty table, I call the procedure with PricingHeaderID_In set to zero in order to invoke the INSERT logic.
Lookup1 obviously finds nothing, because there is nothing to find, and pricingHeaderID1 is NULL. Then, the new row is inserted, Lookup2 retrieves the newly inserted row as expected, and pricingHeaderID2 shows the correct value.
Now, I call the procedure with EXACTLY the same values everywhere, Lookup1 still finds nothing, and pricingHeaderID1 is NULL. That causes the insert logic to run, and MySQL correctly detects a duplicate.
My question is simple: If MySQL can detect that the values will cause a duplicate key, then why is Lookup1 failing?
Here's my table definition:
CREATE TABLE PricingHeaders (
PricingHeaderID bigint NOT NULL AUTO_INCREMENT,
UserID bigint NOT NULL,

Your basic problem is your call to the second procedure,
which must look like
CALL ExtendSession(Token_In, #tokenValidated)
Whe4n you want to retrieve an OUT variable in MySQL#

Even tho I wrote the Oracle Procedure, I have zero clue how to write the same behavior in MYSQL and more over how to fix this error. If there is a alternative to do the same without cursors, then it would be fine too

The table mqttpacket is a system versioned table. Here are the table creation queries.

So, when I first call the stored procedure, my result_message variable returns "Query performed successfully. Effected rows : 53" however MySql says
Affected rows: 107 Found rows: 0 Warnings: 0 Duration for 1 query: 0.015 sec.
In the second call of the SP, it says
Affected rows: 160 Found rows: 0 Warnings: 0 Duration for 1 query: 0.031 sec.
Thankful for any help in advance.

MySQL store procedure syntax error

My mysql version is 5.5 and when run this mysql store procedure it's return this error.
Code:
CREATE DEFINER = CURRENT_USER PROCEDURE `getReceiptNumber`(IN bankcode
varchar,IN receipttype varchar,OUT seq int)
BEGIN
update receipt_number
set seq_number = (seq_number + 1)
where bank_code = bankcode and receipt_type = receipttype;
select seq_number from receipt_number where bank_code = bankcode and
receipt_type = receipttype into seq;
END;
Table Structure:
CREATE TABLE `receipt_number` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`bank_code` varchar(255) DEFAULT NULL,

`receipt_type` varchar(255) DEFAULT NULL,

Create Table and Insert using stored Procedure

I'am trying to create a procedure checking table and insert
but it show me some error which i'am not sure how to fix it
this is the error code
Explicit or implicit commit is not allowed in stored function or
trigger
DELIMITER ;;
CREATE FUNCTION `getLabel`(paradocid INT, paradoctype char(10),paradoclineid INT,paraqty INT,paracreated date,paracreatedby INT) RETURNS int(100)

As the error message says, explicit or implicit commit is not allowed in stored function or trigger. CREATE TABLE statement causes an implicit commit, therefore it is not allowed in a function.
Your code does not seem to return any value (there is no return statement in the function's body) and what you are doing there should be done in a stored procedure, rather than in a function.
