Question

Is it possible to insert columns into a MySQL table??

I’ve created a table and named it “my_table” – I do not understand, why MySQL does not eats my syntax…

INSERT INTO "my_table"(
    "item" char(1) NOT NULL DEFAULT '',
    "price" int(10) NOT NULL DEFAULT '3000',
    "level" int(10) NOT NULL DEFAULT '1000',
    "super" char(1) NOT NULL DEFAULT '',
    "play" char(1) NOT NULL DEFAULT ''
)

Error message:

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 ‘”my_table”( “item” char(1) NOT NULL DEFAULT ”, “price” i’ at line 1

So what’s wrong with my syntax ?

If you’re trying to add columns to an already created table you must use ALTER.

ALTER TABLE my_table ADD item char(1) NOT NULL DEFAULT '';
