GetInfoCatalogUsage

Applications can call SQLGetInfo with the SQL_CATALOG_USAGE option to determine the classes of SQL statements in which catalog and schema names can be used to qualify objects of SQL statements. Setting the GetInfoCatalogUsage parameter of the StarSQL driver allows you to customize the bitmask that is returned by SQLGetInfo() for SQL_CATALOG_USAGE.

Set GetInfoCatalogUsage to 0 to force StarSQL to report that it does not support three-part naming (no Catalog). This may be necessary in some situations, such as when using StarSQL to perform queries to a SQL Server linked server. If GetInfoCatalogUsage contains an empty string or -1, the normal bitmask is returned.
