Views need to have existing columns. What is $1 supposed to be? A geometry column from a different table, or the same table? If you needs are only temporary, then explore the uses of "select * into <b>temp </b>tt from ..." then use tt like any other table until you don't need it anymore in the transaction, then it disappears out of sight.</div>
