Sql - Exists not working properly



Hello Caspio community!

I have a little idea but i can't make it work, is something like this:

  WHEN EXISTS(SELECT name FROM myTable WHERE name = target.[@field:name]) THEN 1

My problem i get the "Not records found" of Caspio instead of 0 and i don't know where i'm mistaking. In the future I pretend to count how much tickets a client have and show it, if that client never create  a ticket is not going to be in myTicketsTable yet for obvious reasons

Hi @HappyAlligator - are you using a Report DataPage? If yes, I suggest using the Filter and Criteria in your Report. Or you can use View instead. For more information, you can check these links:

Yes, i am using a Report Datapage, I tried to use:

FROM _v_My_View
WHERE My_View_name = target.[@field:name]

but don't work either so i decided to go for something much more simple in the beginning (what i post before) to see if i can make it work.

The problem in general as far i can see is when there is no such target.[@field:name] in my table/view when instead of 0 or NULL i just get "error". @Meekeeemaybe you know what to do, i ran out of ideas.

Hello @HappyAlligator,

If you are getting No records found in the report, make sure that there is at least one record on your Table. Then, to check if the value is existing in the Table or not, you can use this formula:

CASE WHEN (SELECT Count(Name) FROM Table WHERE Name = target.[@field:Name]) < 0 THEN 1 ELSE 0 END

Hope this helps! :)
