Syntax
Details

Syntax

SUBSET <selection-criteria>;


Details

You use the SUBSET statement to specify selection criteria when you create a view descriptor. This statement is optional; if you omit it, the view retrieves all the data (that is, all the rows) in the DBMS table.

An editing statement, such as SUBSET, must follow the CREATE statement when you create a view descriptor. See CREATE Statement for more information about the order of statements.

The selection-criteria argument can be either a WHERE clause or a SORT clause. For more information about the WHERE clause, see WHERE Clause in an ADABAS View Descriptor. For more information about the SORT clause, see SORT Clause in a View Descriptor. You can use either SAS variable names or DBMS column names, in your selection criteria. Specify your WHERE clause and SORT clause by using separate SUBSET statements. For example, you can submit the following SUBSET statements:

    subset where jobcode = 1204;
    subset sort lastname;

SAS does not check the SUBSET statement for errors. The statement is verified and validated only when the view descriptor is used in a SAS program.

To delete the selection criteria, submit a SUBSET statement without any arguments.
