The ODBC_SQLSetDescField command sets the value of a single field of a descriptor record.
connectionID is a valid connection ID returned by ODBC_SQLAllocConnect and a connection must be established using the ODBC_SQLConnect command.
Descriptor records are numbered from 1, with recNumber equal to 0 being the bookmark record. The recNumber argument must be less than or equal to the value of SQL_DESC_COUNT. If recNumber is less than or equal to SQL_DESC_COUNT but the row does not contain data for a column or parameter, a call to ODBC_SQLSetDescField will return the default values of the fields.
recNumber is the descriptor record number.
fieldIdentifier is the field of the descriptor whose value is to be set.
valuePtr is a pointer to the variable to set fieldIdentifier.
For more information, please see the SQLSetDescField function in the MS ODBC API Reference at http://msdn.microsoft.com/en-us/library/ms713560(VS.85).aspx.
