I was thinking if this was possible in some way..
I have this table where we have X and Y coordinates, and i need to
select several in one go.
# select * from xy where (x = 1 and y = 2) or (x = 2 and y = 2);
This works but are not so nice looking.
It would be nice to be able to do it like this:
I was thinking of using cursors as a paging mechanism for an application.
Let's say I need to fetch pagenr from a table.
If I use these commands from the client it works:
BEGIN WORK;
DECLARE my_cursor CURSOR FOR
SELECT * FROM test1 ORDER BY id ASC
FOR READ ONLY;
MOVE pagenr*pagesize IN

Hello!
Can I execute VACUUM ANALYZE from ecpg?
How I do that???
/*
I do: EXEC SQL VACUUM ANALYZE table;
But I get error: 'ERROR: VACUUM cannot run inside a transaction block'

Turn on/off autocommit maybe?
Or fake it with EXEC SQL COMMIT; VACUUM
