Question

What’s wrong with this SQL? Why can’t I run it?

CREATE TABLE `test` (

`format_id` VARCHAR NOT NULL ,
bef_aft_flag TINYINT NOT NULL ,
 "order"INT NOT NULL ,
`format_name` VARCHAR( 0 ) NOT NULL ,
`file_path` VARCHAR( 0 ) NOT NULL ,
`create_date` TIMESTAMP NOT NULL ,
`update_dat` TIMESTAMP NOT NULL ,
PRIMARY KEY ( `format_id` )
);


#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 'NOT NULL , bef_aft_flag TINYINT NOT NULL , "order"INT NOT NULL , `format_name` ' at line 3

Answer 1

VARCHAR requires length of the filed in parenthesis. You need this,

`format_id` VARCHAR(10) NOT NULL,

But it might be wrong, just keep reading. There are a lot of problems in your code.

1. From its name, format_id seems INT not character sequence. Did you mean

   format_id INT NOT NULL,

2. double quote in "order" not supported in MySQL use backtick

   `order` INT NOT NULL,
   

3. 0 length VARCHAR on format_name and file_path does not make sense. Did you mean?

   `format_name` VARCHAR( 40 ) NOT NULL,
   `file_path` VARCHAR( 40 ) NOT NULL,
   

4. Did you miss any e on update_dat field. It seems you didn’t miss it on create_date at all.

   `update_date` TIMESTAMP NOT NULL,
