Hello EE,

Let'say i have 2 tables.

First table has:   ID, Description
Second has ID, (same id that table1)

in first table i have values:    1,2,3,4,5

how can I do a SELECT that if there is nothing in table 2  it returns  1,2,3,4,5  if lets say there is 1 and 3 it will return 1,2,4,5

lets say in table 2 there is 4,5  it would return 1,2,3
