Alright, first things first. Log in to the Xano dashboard with your credentials. Easy peasy.

Once you're in, head over to the "Database" section on the left sidebar. This is where all your data tables hang out.

Now, click on the table you want to work with. This will open up the table details for you.

Next, go to the "API & Add-Ons" section. Pick the endpoint where you want to add your custom query.

Click on the endpoint to open its configuration. Scroll down to the "Function Stack" section and hit "Add Function Stack."

In the pop-up menu, choose "Custom Query" from the list of functions. This is where the magic happens.

Now, write your specific SQL code. Whether it's SELECT, INSERT, UPDATE, DELETE, or something more complex like JOINS and subqueries, this is your canvas.

If your query needs parameters, define them using the parameter binding options. This makes your query dynamic and flexible.

After writing your query, use the "Test" feature to run it and see if it returns what you expect. Tweak as needed.

Happy with your query? Great! Click "Save" to store it and then deploy the endpoint to make it live.

Keep an eye on your query's performance using Xano's debugging and logging tools. Optimize as needed to keep things running smoothly.

And there you have it! Follow these steps to create and manage custom query execution plans in Xano.
