Hi All,
Can we create a query to find different values based on different criteria =
from a table using case structure. For example
Select Into :DBComment
Case When localComment Is Null Then Comment
When localComment = '123' Then 'Numeric Comment'
Andre,
The only reason to have data for one query in different databases is if
the databases are on different machines. If you're running on PC-type
hardware, you might have to do that some times for performance reasons.
But if at that point, you should ask yourself if you shouldn't invest in

No, it is quite clear. See:

Hi Esteban,
Your problem looks familiar to me,
and it seems you did not follow my advice.
Anyway, here is a C sample program which works.
It has nothing to do with wrong types, but with a
missing connection, but see for yourself.
/*
/opt/pgsql/bin/ecpg -o sampleprog01.c sampleprog01.sql
Just my two cents on the issue:
A good reason would be having several databases which
each use the same set of tables which contain some information
which takes a lot of storage, such as dictionaries or map
information. You wouldn't want to maintain several copies
of 500 Mb tables, especially
Delete from partitur where userid NOT IN (SELECT DISTINCT ON (userid)
userid, val, ts FROM partitur)

Hi,
I'd like to do a query where can be possible I access tables from
diferent databases on the same query.
On MySQL, I do:
SELECT People1.PersID, People1.Name, Result1.Value, Result1.Date FROM
Database1.People1, Database2.Result1 WHERE ...
I think on ORACLE works like as:
SELECT
have a look at pg_hba.conf in your data dir. it's all in there.

First, I may be wrong but I do think they would prefer if you did not cross-post
(especially to hackers).
Second I think it probably make more sense to make two different triggers here.
If you really wanted to do it that way you might want to try executing that part.
