ODBC_SQLGetFunctions

4D v16


ODBC_SQLGetFunctions ( connectionID ; functionIdentifier ; infoValuePtr ) -> 戻り値

引数	型	説明
connectionID	倍長整数	Connection ID
functionIdentifier	倍長整数	Function identifier
infoValuePtr	ポインター	Indicates if a function is supported or not by the driver
戻り値	倍長整数	Returns the result of the MS ODBC API function SQLGetFunctions

説明

The ODBC_SQLGetFunctions command allows you to determine which specific ODBC functions a driver supports.

connectionID is a valid connection ID returned by ODBC_SQLAllocConnect and a connection must be established using the ODBC_SQLConnect command.

functionIdentifier is the identifier of the function to test to see if it is supported by the driver and can be one of the values below:

infoValuePtr is a pointer to a Longint variable that will be equal to either SQL_TRUE if the specified function is supported by the driver or SQL_FALSE if it is not supported.

ODBC_SQLGetFunctions returns SQL_SUCCESS if the function executes correctly.

For more information, please see the SQLGetFunctions function in the MS ODBC API Reference at http://msdn.microsoft.com/en-us/library/ms709291(VS.85).aspx.

Function Results

SQL_SUCCESS, SQL_SUCCESS_WITH_INFO, SQL_ERROR, or SQL_INVALID_HANDLE.
