Using Array in API, Query?


I am new to Retool and I want to convert the array data obtained from a database select statement into a string. I tried using {{}}, but it's not working. Is there any other way to do it?


The user was seeking a solution to convert an array of data retrieved from a database select statement into a string. They tried using the .toString() method, but it didn't work in Appsmith. After some exploration, they found a working solution using the .map() method to extract the desired data from the array and then using .toString() to join the extracted values into a string. The final solution was: {{ => item.deviceId).toString()}}.
