colID
The ID number of the column. The value must be in the range [0,ULDataReader.FieldCount-1]. The first column in the
cursor has an ID value of zero.
The name of the column or a null reference (Nothing in Visual Basic) if the column has no name. If the column is aliased in
the SQL query, the alias is returned.
Note that in result sets, not all columns have names and not all column names are unique. If you are not using aliases, the
name of a non-computed column is prefixed with the name of the table the column is from. For example, MyTable.ID is the name
of the only column in the result set for the query "SELECT ID FROM MyTable".
This method is identical to the ULCursorSchema.GetColumnName method.
