Fields

columnDB :: !ByteString
Database for table.
columnTable :: !ByteString
Table of column, if column was a field.
columnOrigTable :: !ByteString
Original table name, if table was an alias.
columnName :: !ByteString
Name of column.
columnOrigName :: !ByteString
Original column name, if an alias.
columnCharSet :: !Word16
