ACCESS Procedure

DROP Statement

Drops a column so that it cannot be selected in a view descriptor
Interaction: RESET, SELECT


Required Argument

specifies the column name or the positional equivalent from the LIST statement, which is the number that represents the column's place in the access descriptor. For example, to drop the third and fifth columns, submit this statement: drop 3 5;


The DROP statement drops the specified column(s) from a descriptor. You can drop a column when creating or updating an access descriptor; you can also drop a column when updating a view descriptor. If you drop a column when creating an access descriptor, you cannot select that column when creating a view descriptor that is based on the access descriptor. The underlying DBMS table is unaffected by this statement.
To display a column that was previously dropped, specify that column name in the RESET statement. However, doing so also resets all column attributes (such as the SAS variable name and format) to their default values.
