error 1178: syntax error in a stored procedure in mariadb columnstore - sql

Question

I try to produce a stored procedure that allows me to update many tables in my database but when I try to execute it with a columnstore engine, i get an error of procedure syntax not supported. I have looked for it in the web but do not manage to find where is the issue. If you have an idea, I let you the procedure here.
DELIMITER $$
CREATE PROCEDURE update_sp_aggregated()
BEGIN
DECLARE finished INTEGER DEFAULT 0;
DECLARE tableName varchar(255) DEFAULT "";
DECLARE cursor_update
CURSOR FOR
SELECT table_name FROM INFORMATION_SCHEMA.TABLES WHERE table_name like 'sp_aggr%' ;
OPEN cursor_update;
updateAggregated: LOOP
FETCH cursor_update into tableName;
IF finished = 1 THEN
LEAVE updateAggregated;
END IF;
SET #sql = CONCAT('ALTER TABLE ', tableName, ' ADD COLUMN col2 varchar(5)');
PREPARE stmt FROM #sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
SET #sql = CONCAT('UPDATE ', tableName, ' SET col2= LEFT(col1, 1)');
PREPARE stmt FROM #sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
END LOOP updateAggregated;
CLOSE cursor_update;
END $$
-- declare NOT FOUND handler
DECLARE CONTINUE HANDLER
FOR NOT FOUND SET finished = 1;
DELIMITER ;
CALL update_sp_aggregated();

Finally found, so as tell in my comment, the issue was the update command was not allowed.
to solve it, you need to change the variable infinidb_vtable_mode by setting it to 0.
All is described here
