I have 5 databases which are shown below.
I am trying to drop test database by using "drop database test". But when i check list of databases than test database also shown in that list.
What should I do now?
How i can resolve this issue?
Yeah you are missing the semi-colon. When psql changes from = to - in the prompt, it means you haven’t finished the query.

When I try to use SQLSHELL "CREATE DATABASE test". I don't get a prompt that anything was created (not sure if i'm supposed to). Then when I check to see if it was created ("\l"). Nothing is there.
What is happening?
You have to terminate SQL commands with ;.
In your case:
CREATE DATABASE test;

I'm thinking something in the lines of DBMS_OUTPUT.PUT_LINE in Oracle, it allows you to trace what's going on in a stored procedure in the exactly same way you would use printf, puts or some other STDIO writing proc in a "normal" programming language, i.e.
DBMS_OUTPUT.PUT_LINE('I got here:'||:new.col||' is the new value');
is there any way of doing this in Postgres?
If not, what's the "community way" of doing this? Creating a table with a string row and inserting debug values there?
You can use RAISE NOTICE like this:
RAISE NOTICE 'I got here:% is the new value', NEW.col;

pgAdmin III faulty behavior?

I have a view in my database (PostgreSQL) and I would like to see it's code.
I wrote this query:
select definition from pg_views where viewname='x'
this works most of the time, However in some of the views when the select code is long I get at some point (...)
for example this is one of the results of query where it shows (...):
" SELECT f.selectid,
a.clientid,
a.orderid,
a.clientname,
c.part,
c.product,
c.okey,
e.contry,
d.city,
(
CASE
WHEN (b.dateofissue IS NULL) THEN
CASE
(...)"
This is only part of the code... Why it doesn't show me the whole code?
In pgAdmin III, under Query tool options:
pgAdmin Query tool Options
You want pg_get_viewdef, but I suspect you'll have the same issue there. The problem is probably that the client application is truncating the returned query.
If you're using PgAdmin-III this is in the FAQ.
If you're using psql this shouldn't happen.

Closed 6 years ago.
I have a dump file of memory >1.0GB. It seems highly impossible to edit to take only few tables with structure and data.
I know that exporting with only perticualr table.
But, Is it possible to import only some table with "mysqldump" import and export query ?
You can try importing the whole DB and exporting the table(s) that you need, and then importing them again to a new DB.

Below may work for your needs. If you are on the console be careful with the results, likely you don't want to kill a postgres owned process.
