Issue with MySQL VIEW column size
Posted on 2009-04-13
Hi,
I have Product table with columns prod_id int(11),category_id int(11),prod_name varchar(255) and prod_quantity varchar(255).
I am creating VIEW in MySQL using above table and following syntax:
CREATE OR REPLACE VIEW product_view AS
SELECT
category_id,
CONCAT("#",GROUP_CONCAT(CO
FROM
product
GROUP BY category_id
Now when i describe VIEW then the column size of VIEW COLUMN "product_quantity_values" shows varchar(343). So this view only allow me to store 343 characters in COLUMN "product_quantity_values" . More than that are truncated.
Is there any way to avoid such behavior? I want the VIEW COLUMN "product_quantity_values" should store more characters.

please try this:
CREATE OR REPLACE VIEW product_view AS
SELECT
category_id,
cast(CONCAT("#",GROUP_CONCAT(CONCAT_WS('=',prod_name,prod_quantity) SEPARATOR '#'),"#") AS product_quantity_values as VARCHAR(65000))
FROM
product
GROUP BY category_id
Hi angelIII,
Its giving a error:
Error Code : 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 'AS fproduct_quantity_values as VARCHAR(65000))
BTW: I am using MySQL 5

Hi,
Above issue has been resolved.
MySQL 5 CAST function allows type as CHAR Not VARCHAR.
But thanks for giving way to tackle situation.
