the problem is: COPY can write data returned by a SELECT statement to a
file. our idea is to implement precisely that.
example:
COPY TO file_name USING some_select_statement;
I have run into plenty of cases where I wanted to dump part of a
structure and this could be used for that, but I've always found that
temporary tables were sufficient and equally SQL scriptable
CREATE TEMP TABLE tab AS SELECT ...; COPY tab TO file_name;
Hi Rod,
TEMP TABLE are not suitable for my case. Using a temp table would
essentially mean that we had to store the data 3 times: Original data,
temp table + dump. Temp tables are only fine for small amounts of data
but we are talking about too much data here (my smallest export will
contain 15.000.000 records).
Best regards,
Hans
