Run Batch File In postgresql in single click
To run a batch file from PostgreSQL using a single SQL query, you can use the \!
command provided by psql
(the PostgreSQL command-line utility). This allows you to execute shell commands from within the psql
prompt. Here's how you can do it:
Open
psql
Command-Line Utility:
Open your command prompt or terminal and run thepsql
command to connect to your PostgreSQL database.shpsql -h your_host -d your_database -U your_user
Replace
your_host
,your_database
, andyour_user
with your actual database connection details.Run Batch File:
Within thepsql
prompt, you can use the\!
command to run a batch file or any shell command. For example:sql\! C:\path\to\your\batchfile.bat
Replace
C:\path\to\your\batchfile.bat
with the actual path to your batch file.Exit
psql
:
After running the batch file, you can exit thepsql
prompt using the command:sql\q
Keep in mind that using the \!
command to execute shell commands from within psql
can have security implications, as it allows you to execute arbitrary commands on the operating system. Only run trusted commands and scripts.
Additionally, note that this approach executes the batch file on the machine where the psql
utility is running, not within the PostgreSQL server itself. If you need to execute batch files on the server machine, you might consider using external tools or languages like Python or a server-side programming language within PostgreSQL (e.g., PL/pgSQL) to achieve your goals.
