Question

field type when create table in mysql

Asked by: RupertA

If you look at my attached code at the bottom I create a basic table, where I am just putting in "Passed" for all brands from a table. By default it sets the "Passed or Not passed" field to varchar(6). I would like for it to be set to varchar(15) as I need it like that for later. If this possible? I tried following and it didn't work. Thanks.

$query = "CREATE TABLE month_raw6
SELECT
Brand,
\"Passed\" as \"Passed or Not passed\" varchar(15)
FROM month_raw5
GROUP BY Brand";

$query = "CREATE TABLE month_raw6
SELECT 
Brand,
\"Passed\" as \"Passed or Not passed\"
FROM month_raw5
GROUP BY Brand";

try execute an ALTER statement to amend the field property after that? like:

ALTER TABLE month_raw6
MODIFY COLUMN `Passed or Not passed` VARCHAR(15);


get the idea?

 

by: ushastryPosted on 2009-09-21 at 03:53:12ID: 25381627

No, You cannot use the SELECT statement as CREATE table expects a legal statements.

But you can try this as.. pls change the column type of Band to as appropriate 

CREATE TABLE month_raw6(Brand varchar(15),Passed varchar(15))
SELECT
Brand,
\"Passed\" as \"Passed or Not passed\"
FROM month_raw5
GROUP BY Brand

I just went with ryan's alter statement, though ushastry's works just as well. Thanks for the explanation as well ushastry. Splitting points 50/50. Thanks.
