Here is how youcan use SAS/ACCESS software for relational databases for PROC SQL interactions.3 You can assign a libref to a DBMS using the SAS/ACCESS LIBNAME statementand reference the new libref in a PROC SQL statement to query, update, or deleteDBMS data. (See Chapter 10, “The LIBNAME Statement for RelationalDatabases,” on page 87.)3 You can embed LIBNAME information in a PROC SQL view and thenautomatically connect to the DBMS every time the PROC SQL view is processed.(See “SQL Views with Embedded LIBNAME Statements” on page 90.)3 You can send DBMS-specific SQL statements directly to a DBMS using anextension to PROC SQL called the SQL pass-through facility. (See “Syntax for theSQL Pass-Through Facility for Relational Databases” on page 426.)Overview of the SQL Pass-Through FacilityThe SQL pass-through facility uses SAS/ACCESS to connect to a DBMS and to sendstatements directly to the DBMS for execution. An alternative to the SAS/ACCESSLIBNAME statement, this facility lets you use the SQL syntax of your DBMS. Itsupports any SQL that is not ANSI-standard that your DBMS supports.
