Psql команда не найдена windows

PostgreSQL is a popular open-source relational database management system. On Windows, the default installation of PostgreSQL does not add the psql executable to your system’s PATH. As a result, you may receive the «psql: command not found» error when trying to run psql from the command prompt.

In this article, we’ll explore several ways to resolve this issue and run psql on Windows.

Option 1: Adding psql to the PATH

One of the easiest ways to resolve the «psql: command not found» error is to add the psql executable to your system’s PATH. Here’s how:

1. Open the Start menu and search for «Environment Variables».
2. Click on «Edit the system environment variables».
3. In the System Properties dialog box, click on the «Environment Variables» button.
4. Scroll down to the «System variables» section and locate the «Path» variable.
5. Click on the «Edit» button to modify the PATH.
6. Click on the «New» button and add the path to the psql executable, which is typically located at C:\Program Files\PostgreSQL\[version number]\bin.
7. Close the dialog boxes and open a new command prompt window.

You should now be able to run psql from the command prompt.

Option 2: Running psql with the full path

Another option is to run psql with the full path to the executable. Here’s an example:

C:\Program Files\PostgreSQL\[version number]\bin\psql.exe

This method is useful if you only need to run psql occasionally and don’t want to add it to your system’s PATH.

Option 3: Creating a Shortcut to psql

A third option is to create a shortcut to psql on your desktop or in your Start menu. Here’s how:

1. Locate the psql.exe file in the bin directory of your PostgreSQL installation (e.g., C:\Program Files\PostgreSQL\[version number]\bin\psql.exe).
2. Right-click on the file and select «Create Shortcut».
3. Drag the shortcut to your desktop or Start menu.

You can now run psql by double-clicking the shortcut.

Option 4: Running psql from the PostgreSQL Installation Directory

Finally, you can run psql from the PostgreSQL installation directory by navigating to the bin directory in the command prompt and executing the psql command. Here’s an example:

cd C:\Program Files\PostgreSQL\[version number]\bin
psql

This method is useful if you need to run psql frequently and don’t want to add it to your system’s PATH or create a shortcut.

Conclusion

In this article, we explored several ways to resolve the «psql: command not found» error on Windows and run the psql executable. Whether you choose to add psql to your system’s PATH, run it with the full path, create a shortcut, or run it from the PostgreSQL installation directory, you should now be able to use psql on your Windows system.

Connecting to a Database using psql

Once you have resolved the «psql: command not found» error, you can use the psql command to connect to a PostgreSQL database. The basic syntax for connecting to a database is as follows:

psql -U [username] -d [database name]

where username is the name of the database user and database name is the name of the database you want to connect to. For example:

psql -U postgres -d mydatabase

This will prompt you for a password for the postgres user. Once you have entered the password, you will be connected to the mydatabase database.

Basic psql Commands

Once you are connected to a database using psql, you can run various SQL commands to manipulate the data in the database. Here are some basic psql commands:

• \l: List all databases.
• \c [database name]: Connect to a different database.
• \dt: List all tables in the current database.
• \d [table name]: Describe the columns in a table.
• \q: Quit psql.

For a complete list of psql commands, you can run the \? command while in the psql prompt.

Importing and Exporting Data with psql

In addition to running SQL commands, you can also use psql to import and export data to and from a PostgreSQL database. Here are some examples:

Exporting Data

To export data from a table to a file, you can use the \copy command in psql. The basic syntax is as follows:

\copy [table name] to '[file name]' with (format '[format]');

where table name is the name of the table you want to export, file name is the name of the file you want to export to, and format is the format of the exported data (e.g., csv, tab, etc.). For example:

\copy mytable to 'mytable.csv' with (format 'csv');

This will export the data from the mytable table to a file named mytable.csv in CSV format.

Importing Data

To import data from a file into a table, you can use the \copy command in psql. The basic syntax is as follows:

\copy [table name] from '[file name]' with (format '[format]');

where table name is the name of the table you want to import to, file name is the name of the file you want to import, and format is the format of the imported data (e.g., csv, tab, etc.). For example:

\copy mytable from 'mytable.csv' with (format 'csv');

This will import the data from the mytable.csv file into the mytable table.

In conclusion, psql is a powerful tool for managing PostgreSQL databases on Windows. With the ability to connect to databases, run SQL commands, and import and export data, psql is a valuable tool for developers and database administrators

— Set Path Using Edit System Environment Variables

Setting Path Using Command Prompt

Open the windows search menu by pressing the “🪟 + S” button. Search CMD, and launch it as an administrator. Once the CMD terminal is open, execute the “setx” command to set the path for the Postgres tools using CMD:

setx /M path "%PATH%;C:\Program Files\PostgreSQL\15\bin"

In this command:

— “/M” is used to set the variable at the SYSTEM level/scope.
— “15” represents the Postgres version installed on our system. You must replace the with the Postgres version installed on your OS:

The Postgres bin directory’s path has been set successfully. For confirmation, you can re-launch the CMD and type any psql command:

The Postgres version confirms that the stated error has been rectified.

Setting Path Using Edit System Environment Variables

Open the “Edit the System Environment Variables” settings from the Windows search menu:
