试试这个: SQLRETURN SQLGetInfo( SQLHDBC ConnectionHandle, SQLUSMALLINT InfoType, SQLPOINTER InfoValuePtr, SQLSMALLINT BufferLength, SQLSMALLINT * StringLengthPtr);SQLUSMALLINT InfoType: SQL_DATA_SOURCE_NAME returns the value passed as DSN to SQLConnect, or SQLDriverConnect; returns an empty string if no DSN is specified. SQL_DATA_SOURCE_READ_ONLY returns 'N'. SQL_DATABASE_NAME returns a full UNC path to the current database if the data source is a database. If the data source connects to a directory of tables, the function returns the path to the directory. SQL_DBMS_NAME returns "Visual FoxPro". SQL_DBMS_VER returns "03.00.0000". SQL_DEFAULT_TXN_ISOLATION returns SQL_TXN_READ_COMMITTED. Dirty reads are not possible, but nonrepeatable reads and phantoms are possible. SQL_DRIVER_HDBC is implemented by the Driver Manager. SQL_DRIVER_HENV is implemented by the Driver Manager. SQL_DRIVER_HLIB is implemented by the Driver Manager. SQL_DRIVER_HSTMT is implemented by the Driver Manager. SQL_DRIVER_NAME returns "vfpodbc.dll". SQL_DRIVER_ODBC_VER returns "02.50" (SQL_SPEC_MAJOR, SQL_SPEC_MINOR). SQL_DRIVER_VER returns "01.00.0000". 更多的内容参考MSDN
