SQLGetInfo (dBASE Driver)

  • Artikkeli

Note

This topic provides dBASE Driver-specific information. For general information about this function, see the appropriate topic under ODBC API Reference.

SQLGetInfo supports the SQL_FILE_USAGE information type. The returned value is a 16-bit integer that indicates how the driver directly treats files in a data source:

  • SQL_FILE_NOT_SUPPORTED - The driver is not a single-tier driver.

  • SQL_FILE_TABLE - A single-tier driver treats files in a data source as tables.

  • SQL_FILE_QUALIFIER - A single-tier driver treats files in a data source as a qualifier.

The ODBC driver returns SQL_FILE_TABLE because each file is a table.
