what should i do? thanks all
change database name from postgres to xwpgagbb similar to:
see user AND DEFAULT DATABASE are the same?..
I have a sample database from this tutorial. I want to work with this database in Dbeaver. When I provide a path to the database in Dbeaver I get an error.
What is the procedure to work with the database in Dbeaver?
Install pgAdmin and follow the tutorial you linked. Following, expand the Databases tab in the left. There you will see all the available databases. There should be the one you have imported - probably named "dvdrental" or so. Then just type in the database name in the Database field in dbeaver
I am connecting to my PostgreSQL DB on AWS RDS through SQL workbench. i have created a new table. it created successfully. table name is like public.xyz.
Now when i am trying to access the select query on 'public.xyz' i am getting error like
'Relation public.xyz does not exist'.
i have checked that my show_path contains %user,public. no case issue.
i have tried select query like select * from public.xyz and select * from xyz etc.. all have same issue
please suggest.
it seems to be a problem with SQL workbench. when i tried to create table using psql client on a linux machine, it worked properly. now i am able to run the same select query which was failing earlier. don't know inner details, but it seems to be an issue with SQL workbench.
I have the following code to generate the schema for a database in Nhibernate
new SchemaExport(configuration).Execute(true, true, false);
but when run against a PostgreSQL database, I end up getting the following error
[NpgsqlException (0x80004005): FATAL: 3D000: database "dbname" does not exist]
If I however create the database manually, the schema is exported without errors. An so the question: Why is Nhibernate SchemaExport unable to create a PostgreSQL database and yet this works against other databases like SQLite, MsSqlCe and MsSql Server.
I have searched for online literature but have been unable to locate any highlighting on this issue.
I am using Nhibernate 3.3.1 with PostgreSQL 9.2.
You must create the database before you can create the tables and other objects within the database.
Do this with a CREATE DATABASE statement on a PostgreSQL connection - either in your app, or via psql or PgAdmin-III.
PostgreSQL doesn't support creating databases on demand / first access. Perhaps that's what your tool is expecting?
If you think the DB does exist and you can see it in other tools, maybe you're not connecting to the same database server? Check the server address and port.
I am beginner to PostgreSQL.
I want to connect to another database from the query editor of Postgres - like the USE command of MySQL or MS SQL Server.
I found \c databasename by searching the Internet, but its runs only on psql. When I try it from the PostgreSQL query editor I get a syntax error.
I have to change the database by pgscripting. Does anyone know how to do it?
When you get a connection to PostgreSQL it is always to a particular database. To access a different database, you must get a new connection.
Using \c in psql closes the old connection and acquires a new one, using the specified database and/or credentials. You get a whole new back-end process and everything.
You must specify the database to use on connect; if you want to use psql for your script, you can use "\c name_database"
user_name=# CREATE DATABASE testdatabase;
user_name=# \c testdatabase
At this point you might see the following output
You are now connected to database "testdatabase" as user "user_name".
testdatabase=#
Notice how the prompt changes. Cheers, have just been hustling looking for this too, too little information on postgreSQL compared to MySQL and the rest in my view.
In pgAdmin you can also use
SET search_path TO your_db_name;
The basic problem while migrating from MySQL I faced was, I thought of the term database to be same in PostgreSQL also, but it is not. So if we are going to switch the database from our application or pgAdmin, the result would not be as expected.
As in my case, we have separate schemas (Considering PostgreSQL terminology here.) for each customer and separate admin schema. So in application, I have to switch between schemas.
For this, we can use the SET search_path command. This does switch the current schema to the specified schema name for the current session.
example:
SET search_path = different_schema_name;
This changes the current_schema to the specified schema for the session. To change it permanently, we have to make changes in postgresql.conf file.
Use this commad when first connect to psql
=# psql <databaseName> <usernamePostgresql>
set search_path = 'schema name here'
while connecting to the postgres, you have to opt for default database to connect. If you have nothing, you can use 'postgres' as default.
You can use dbeaver to connect to postgres. UI is good
PgAdmin 4, GUI Tool: Switching between databases
In the PgAdmin Browser on the left hand side, right click on the database you are willing to switch to.
Select a QueryTool from the drop down menu (or any other option that you need, I will stick with the QueryTool for now).
You will see the QueryTool in the PgAdmin window, and on top you will see the active database and the role name.
Now you can write queries against the chosen database.
You can open multiple QueryTools for multiple database, and work with them as you do with your graphical text editor.
In order to be sure that you are querying the proper database, issue the following query:
SELECT session_user, current_database();
