Description
The ODBC_SQLGetDescField command returns the current setting or 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 0, with record number 0 being the bookmark record. If the fieldIdentifier argument indicates a header field, recNumber is ignored. 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_SQLGetDescField 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 returned.
valuePtr is a pointer to the variable in which to receive the descriptor information.
For more information, please see the SQLGetDescField function in the MS ODBC API at http://msdn.microsoft.com/library/en-us/odbc/htm/odbcsqlgetdescfield.asp.
Function Results
SQL_SUCCESS, SQL_SUCCESS_WITH_INFO, SQL_ERROR, SQL_NO_DATA, or SQL_INVALID_HANDLE.
SQL_NO_DATA is returned if recNumber is greater than the current number of descriptor records.
