    handle nonexisting columns

    Code:
    select
    IFNULL(t.AB,t.EN) as L
    FROM
    table t
    EN column exists.
    This is ok if t.AB exists, need it to work even if it does not exists, like:

    Pseudocode:
    Code:
    select
    IFNULL_ERROR(t.AB,t.EN) as L
    FROM
    table t
    Is there something like that ?

    no, if you try to select from a column that doesn't exist in the table you will get an error.
