The results from the query serve asa virtual table for the PROC SQL FROM clause.proc sql;connect to odbc as mydb(datasrc="SQL Server" user=testuser password=testpass);select * from connection to mydb(select CUSTOMER, NAME, COUNTRYfrom CUSTOMERSwhere COUNTRY ’USA’);quit;This example returns a list of the columns in the CUSTOMERS table.proc sql;connect to odbc as mydb(datasrc="SQL Server" user=testuser password=testpass);select * from connection to mydb(ODBC::SQLColumns (, , "CUSTOMERS"));quit;Special Catalog QueriesSAS/ACCESS Interface to ODBC supports the following special queries. Manydatabases provide or use system tables that allow queries to return the list of availabletables, columns, procedures, and other useful information. ODBC provides much of thisfunctionality through special application programming interfaces (APIs) toaccommodate databases that do not follow the SQL table structure. You can use thesespecial queries on SQL and non-SQL databases.Here is the general format of the special queries:ODBC::SQLAPI “parameter 1”,”parameter n”ODBC::is required to distinguish special queries from regular queries.
