Обсуждение: How to parse Datum
I met a problem with parsing Datum,
is there any good way to parse this
kind of value? Because I want to get
the value in an attribute of a table.
In TupleTableSlot, there is a tts_values
which is Datum type. Does anyone know how
to parse it?

There are several macros like DatumGetInt and so on. See postgres.h for details. Zdenek Zhe He napsal(a): > I met a problem with parsing Datum, > is there any good way to parse this > kind of value?
