Hello, I don’t know if it’s a bug or something else since this functionality is in beta, but I activated the “More computed columns in Glide Big Tables” option 2 weeks ago, but without using it, I just wanted to see if some bugs happen. Worked fine till yesterday when I used it to create some new columns. Now some lists don’t load, and I have an “unknown error executing query” (they don’t use the new query). So I deactivated this functionality, and all works fine, but this would be very helpful, so please let me know if there is a way to use it. ---

@Axel_THOMAS Can you explain what do you mean by “used it to create some new columns”? Can you include some screenshots? ---

There are two big tables used: **Project** and **Project Items**. In the **Project** table, I’ve made a query to get all the rows in **Project Items** that are related, then made a lookup to retrieve all the dynamic JSON columns. After that, I created another JSON column using the result of the previous lookup. The limitation of 100 rows per lookup is respected. ![Capture d’écran 2025-02-20 à 09.17.01](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/f/7/f7d68aaed0a05f8bf274af26924c67d3bc13efd2.png) ![Capture d’écran 2025-02-20 à 09.17.44](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/5/6/565799a945e472bc620128bacd359feee98e8c49.png) ![Capture d’écran 2025-02-20 à 09.18.04](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/6/a/6aac4612c7a693f673472ef4e1ca50e217419d22.png) ---
