Getting error in sql query

I do it so I am advising you. Just paste your SQL query in chat GPT and paste the error you are getting. It should help you remove the errors. 

Here you go, can you test it please?

DELIMITER //

CREATE PROCEDURE process_batches()
BEGIN
DECLARE batch_size INT DEFAULT 0;
DECLARE batch_limit INT DEFAULT 51; -- Declarar batch_limit
DECLARE done INT DEFAULT 0; -- Variable para controlar la finalización del bucle
DECLARE CONTINUE HANDLER FOR SQLEXCEPTION
BEGIN
ROLLBACK; -- Rollback transaction on error
END;

WHILE batch_size <= batch_limit DO -- Cambiar "WHILE" y agregar "DO"
START TRANSACTION;

UPDATE `CM_AH_Segmentation` SET `Handled` = 1 WHERE `RecordID` <= batch_size;

UPDATE `CM_AccountHolder` AS ah
JOIN `CM_AH_Segmentation` AS cas
ON ah.AccountHolderID = cas.AccountHolderID
AND cas.OldSegment <> cas.NewSegment
SET ah.Segment = cas.NewSegment
WHERE cas.handled = 1;

INSERT INTO `GLB_AuditInfo`(
`ReferenceID`,
`Event`,
`Action`,
`ActorLoginID`,
`AppName`,
`Comment`,
`CreatedOn`
)
SELECT
cahl.CaseID,
'Risk Investigation',
'Update Segmentation',
'System Admin',
'Risk Investigation',
CONCAT(
'Update segment for AH ',
cas.AccountHolderID,
' from ',
cas.OldSegment,
' to ',
cas.NewSegment,
'(',
cas.OldSegment,
')'
),
NOW()
FROM
`CM_AH_Segmentation` cas
JOIN `CM_CaseAccountHolderLink` cahl
ON cahl.AccountHolderORNID = cas.AccountHolderID
WHERE
cas.Handled = 1;

UPDATE `CM_AH_Segmentation` SET `Handled` = 2 WHERE `Handled` = 1;

COMMIT;

SET batch_size = batch_size + 10;

IF batch_size > batch_limit THEN
SET done = 1; -- Si batch_size supera batch_limit, establecer done a 1 para salir del bucle
END IF;
END WHILE;
END //

DELIMITER ;

To improve readability ...
