ALTER TABLE - add several columns - Mailing list pgsql-general

Hi,

I just want to add several columns to an existing table. Do I have to call a statements like below for each new column, or is there a possibility to do it at once?

- existing table:               test
- columns to add:       col1 (FK), col2

ALTER TABLE test ADD col1 INT2 NULL;
ALTER TABLE test ADD CONSTRAINT col1_fk FOREIGN KEY (col1) REFERENCES xy(col1);
ALTER TABLE test ADD col2 INT2 NULL;

I'd rather like to execute a statement like this:

ALTER TABLE test ADD (
        col1 INT2 NULL,
        col2 INT2 NULL,
        FOREIGN KEY (col1) REFERENCES xy(col1)
);

thx,
Clemens
