Automating export of query results to .csv

PaulKraemer's profile image PaulKraemer posted 3 months ago in General Permalink


I just installed HeideSQL and created a session in which I connect to a PostreSQL database. I've never used HeideSQL before, but I have experience with SQL on other platforms and utilities. I've created a simple Query for which (when executed), the results are returned on-screen in a pane located in the middle of the HeideSQL window, just below where I typed the Query. If I right-click on the query results and select "Export Grid Rows", I can export the results of my Query to a .CSV file. I foresee myself wanting to do this regularly for multiple queries. With this in mind, I'm wondering if anyone here can tell me if any of the following are possible:

  1. Write a query (SELECT statement) that would automatically direct the results to a .CSV file (without me having to manually chose "Export Grid Rows" and choose a filename every time).
  2. If (1) above is possible, can I have the filename automatically generated? Most likely I'd like to append the date and time on which the query was run to the filename, to create filenames like MyExport_20240422_1725.csv, for example.
  3. If (2) is possible, can I run multiple queries setup like this in a batch?

Any suggestions will be greatly appreciated.

Thanks in advance, Paul

Automation of HeidiSQL is very limited, and mostly refers to the connection itself, not to things which are done after the connect. There is a section in the help document explaining all supported command line arguments.

For automating exports and other things, you will need to use different tools. For MySQL and MariaDB I always recommend mysqldump. Maybe there is a similar tool for PostgreSQL, I don't know.

Thank you Ansgar,

Before I worry about automating exports, I'll try to get some practice creating the queries I want an running them manually.

I appreciate your help.

Best regards, Paul
