SAS/ACCESS Interface to Sybase IQ 4 Special Catalog Queries 769(host=iqsvr1 server=iqsrv1_users db=users user=iqusr1 password=iqpwd1);select * from connection to dbcon(select * from customers where customer like ’1%’);quit;Special Catalog QueriesSAS/ACCESS Interface to Sybase IQ supports the following special queries. You canthe queries use to call the ODBC-style catalog function application programminginterfaces (APIs). Here is the general format of the special queries:SIQ::SQLAPI “parameter 1”,”parameter n”SIQ::is required to distinguish special queries from regular queries. SIQ:: is not casesensitive.SQLAPIis the specific API that is being called. SQLAPI is not case sensitive."parameter n"is a quoted string that is delimited by commas.Within the quoted string, two characters are universally recognized: the percent sign(%) and the underscore (_). The percent sign matches any sequence of zero or morecharacters, and the underscore represents any single character. To use either characteras a literal value, you can use the backslash character (\) to escape the matchcharacters. For example, this call to SQLTables usually matches table names such asmyatest and my_test:select * from connection to sybaseiq (SIQ::SQLTables "test","","my_test");Use the escape character to search only for the my_test table:select * from connection to sybaseiq (SIQ::SQLTables "test","","my\_test");SAS/ACCESS Interface to Sybase IQ supports these special queries.SIQ::SQLTables returns a list of all tables that match the specified arguments. If you do notspecify any arguments, all accessible table names and information are returned.SIQ::SQLColumns returns a list of all columns that match the specified arguments. If you do notspecify any argument, all accessible column names and information are returned.SIQ::SQLPrimaryKeys returns a list of all columns that compose the primary key that matches thespecified table. A primary key can be composed of one or more columns. If you donot specify any table name, this special query fails.SIQ::SQLSpecialColumns returns a list of the optimal set of columns that uniquely identify a row in thespecified table.SIQ::SQLStatistics returns a list of the statistics for the specified table name, with options ofSQL_INDEX_ALL and SQL_ENSURE set in the SQLStatistics API call. If you donot specify any table name argument, this special query fails.
