    Unanswered: adding multiple columns in one ALTER statement

    Hi to all,

    Is is possible to add 4 or more columns in one ALTER TABLE statement in mySQL? So that I can save a lot of typing, so far I could not figure it out. What I am trying to do is create each ALTER TABLE statement for each new column that I am trying to add.

    Thanks and god bless.

    Code:
    ALTER TABLE daTable
    ADD COLUMN foo INTEGER
    ADD COLUMN bar INTEGER
    ADD COLUMN qux INTEGER

    hey thanks, but your statement lacks a comma.

    I have found out that it should be like this:
    Code:
    ALTER TABLE tblName 
    ADD COLUMN col1 date,
    ADD COLUMN col2 date,
    ADD COLUMN col3 date;
