    Angry Unanswered: join two tables returning unlike data

    How do you return unlike data between two identical tables.

    IE : Table1 , column1,column2,colum3,column4
    Table2 , column1,column2,colum3,column4

    I need the rows that are not in Table2.

    Thanks for the Help

    Re: join two tables returning unlike data

    SELECT a.* FROM myTableA a LEFT JOIN myTableB b
    WHERE a.myKey = b.myKey WHERE b.myKey IS NULL

    is one way...

    The physical order of data in a database has no meaning.

    brett, i think you put one too many where clauses. the first one should be replaced with on.
