RFX_Date_Bulk

Transfers multiple rows of TIMESTAMP_STRUCT data from a column of an ODBC data source to a corresponding array in a CRecordset-derived object.

void RFX_Date_Bulk(
   CFieldExchange* pFX,
   LPCTSTR szName,
   TIMESTAMP_STRUCT** prgTSVals,
   long** prgLengths 
);

Parameters

pFX: A pointer to a CFieldExchange object. This object contains information to define the context for each call of the function. For more information, see the article Record Field Exchange: How RFX Works.
szName: The name of a data column.
prgTSVals: A pointer to an array of TIMESTAMP_STRUCT values. This array will store the data to be transferred from the data source to the recordset. For more information about the TIMESTAMP_STRUCT data type, see the topic "C Data Types" in Appendix D of the ODBC SDK Programmer's Reference.
prgLengths: A pointer to an array of long integers. This array will store the length in bytes of each value in the array pointed to by prgTSVals. Note that the value SQL_NULL_DATA will be stored if the corresponding data item contains a Null value. For more details, see the ODBC API function SQLBindCol in the ODBC SDK Programmer's Reference.

Remarks

The data source column can have an ODBC type of SQL_DATE, SQL_TIME, or SQL_TIMESTAMP. The recordset must define a field data member of type pointer to TIMESTAMP_STRUCT.

If you initialize prgTSVals and prgLengths to NULL, then the arrays they point to will be allocated automatically, with sizes equal to the rowset size.

Note
Bulk record field exchange only transfers data from the data source to the recordset object. To make your recordset updateable, you must use the ODBC API function SQLSetPos.
