Re: How to "use" database?

Hi,

Thank you for you detailed answer, but I am exactly in the case when I want to paste the script and hit F5 and have both the database and tables created.

A problem also comes from the fact that in order to use the query window in pgadmin3, you need to select a database. Then when you create a new database you can not access it by name cause you receive an error "cross database referencing is not allowed".

Cheers,
Anton

Hi,

How to use a database I have just created in a script that I am executing in Pgadmin3 on Windows?

If you are in pgAdmin then you don't need the connect command. When you select the db from the side list it connects you and lists the contents of the db. From the query window in pgAdmin (where you can enter any sql statements) which is where I think you are opening your script file, it will have a popup menu that you can choose the db to run the commands on (or the sql script you are opening).

I can not use "USE Northwind;" or "\connect Northwind;"?

I believe you get the USE command from MS SQL Server examples - postgres doesn't have that command.

The \connect is a 'shell' command used in psql - the cli based postgres client that comes with postgresql. This would not be recognised in the pgAdmin query window, which would only accept valid SQL statements.


I am thinking that if you are writing a script that creates a db then wants to connect to it and create tables etc, you should look at sending it to psql.

From a dos prompt you can use something like -
psql -U postgres -W -f myscript.sql


If you start psql then you can use the psql command \i myscript.sql to run the script.

You may need to add full pathnames in these examples.
