I need to add multiple columns to a table but position the columns after a column called lastname
.
I have tried this:
ALTER TABLE `users` ADD COLUMN ( `count` smallint(6) NOT NULL, `log` varchar(12) NOT NULL, `status` int(10) unsigned NOT NULL ) AFTER `lastname`;
I get this error:
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 ') AFTER
lastname
' at line 7
How can I use AFTER in a query like this?
The syntax to add a column in a table in MySQL (using the ALTER TABLE statement) is: ALTER TABLE table_name ADD new_column_name column_definition [ FIRST | AFTER column_name ]; table_name.
First, you specify the table name after the ALTER TABLE clause. Second, you put the new column and its definition after the ADD COLUMN clause. Note that COLUMN keyword is optional so you can omit it. Third, MySQL allows you to add the new column as the first column of the table by specifying the FIRST keyword.
Try this
ALTER TABLE users ADD COLUMN `count` SMALLINT(6) NOT NULL AFTER `lastname`, ADD COLUMN `log` VARCHAR(12) NOT NULL AFTER `count`, ADD COLUMN `status` INT(10) UNSIGNED NOT NULL AFTER `log`;
check the syntax
