| I have a column "Description" in table called "Standards" and I have column "Standard1", "Standard2" and "Standard3" in Table called "Content".I want to select all the records in "Description" column of table "Standards" that is not in columns "Standard1" or "Standard2" or "Standard3". Right now I am able to select all records in "Description" that is not in "Standard1" by using the following code:select st.description from Standards st where st.description not in (select standard1 from Content)Is there way I can not only look at "Standard1" column but also "Standard2" and "Standard3" |
