The SQL Procedure

DROP Statement

Deletes tables, views, or indexes.

Restriction:

You cannot use DROP TABLE or DROP INDEX on a table that is accessed by an engine that does not support UPDATE processing.

DROP TABLE table-name <, ... table-name>;

DROP VIEW view-name <, ... view-name>;

DROP INDEX index-name <, ... index-name>
FROM table-name;

index-name: specifies an index that exists on table-name.
table-name: specifies a PROC SQL table. table-name can be a one-level name, a two-level libref.table name, or a physical pathname that is enclosed in single quotation marks.
view-name: specifies a SAS view of any type: PROC SQL view, SAS/ACCESS view, or DATA step view. view-name can be a one-level name, a two-level libref.view name, or a physical pathname that is enclosed in single quotation marks.

If you drop a table that is referenced in a view definition and try to execute the view, then an error message is written to the SAS log that states that the table does not exist. Therefore, remove references in queries and views to any tables and views that you drop.
If you drop a table with indexed columns, then all the indexes are automatically dropped. If you drop a composite index, then the index is dropped for all the columns that are named in that index.
You can use the DROP statement to drop a table or view in an external database that is accessed with the Pass-Through Facility or SAS/ACCESS LIBNAME statement, but not for an external database table or view that a SAS/ACCESS view describes.
