CDynamicParameterAccessor::SetParamString

  • Cikk

Sets the string data of the specified parameter stored in the buffer.

bool SetParamString( 
   DBORDINAL nParam, 
   const CHAR* pString, 
   DBSTATUS status = DBSTATUS_S_OK  
) throw( ); 
bool SetParamString( 
   DBORDINAL nParam, 
   const WCHAR* pString, 
   DBSTATUS status = DBSTATUS_S_OK  
) throw( );

Parameters

  • nParam
    [in] The parameter number (offset from 1). Parameter 0 is reserved for return values. The parameter number is the index of the parameter based on its order in the SQL or stored procedure call. See SetParam for an example.

  • pString
    [in] A pointer to the ANSI (CHAR) or Unicode (WCHAR) string data of the specified parameter. See DBSTATUS in oledb.h.

  • status
    [in] The DBSTATUS status of the specified parameter. For information on DBSTATUS values, see Status in the OLE DB Programmer's Reference, or search for DBSTATUS in oledb.h.

Remarks

Returns true on success or false on failure.

SetParamString will fail if you try to set a string that is larger than the maximum size specified for pString.

Use SetParamString to set string parameter data in the buffer. Use SetParam to set nonstring parameter data in the buffer.
