Creating functions within PgAccess is also fairly simple. Click on the Functions tab, then click New . You should now be presented with the "Function" windows. You must now enter the name of your new function, the parameters it takes (comma-separated), the language it is parsed in (be it SQL, C, etc.), and (if the function returns a value) the type of data it returns. Once you've defined those options, enter the body of the function in the white box that takes up most of the screen. Once finished, click Save .

You can run defined functions by selecting them from the function list and clicking Open .
