Select Database - (PostgreSQL Database)
In PostgreSQL, a database is a collection of related data tables, views, indexes, and other objects. In order to work with data in a database, you must first connect to it and select it. In this tutorial, we'll show you how to select a database in PostgreSQL.
Syntax
\c database_name
Example
Let's take a look at an example of selecting a database in PostgreSQL.
\c mydatabase
In this example, we are selecting the database named mydatabase
.
Explanation
The \c
command is used to connect to a database in PostgreSQL. When you run \c
, you need to specify the name of the database you want to connect to. This command can be run from the command line, or from within the psql command-line interface.
Use
The \c
command is used to connect to a database in PostgreSQL. Once you have connected to a database, you can perform various actions on it, such as querying the data or creating new objects within the database.
Important Points
- The user account running the
\c
command must have permissions to connect to and select the specified database. - Database names are case-insensitive in PostgreSQL, so if you select a database with a different case than the name was created with, it will still work.
- If you are connected to a database and want to change to a different database, you will need to disconnect from the current database before connecting to the new one.
Summary
In this tutorial, we showed you how to select a database in PostgreSQL using the \c
command. We discussed the syntax, example, output, explanation, use, and important points of selecting a database in PostgreSQL. With this knowledge, you can now connect to and work with databases in PostgreSQL.
