shredded Posted July 31, 2018 Share Posted July 31, 2018 Trying to pull data (list of DataIDs) where they have null Notes, see image. I want to see the ids from the related layout table Master. Any help in the right direction will be great. thanks. Link to comment Share on other sites More sharing options...
bcooney Posted July 31, 2018 Share Posted July 31, 2018 If I understand correctly, you want a list of master records that do not have notes? SQL can be slow with joins. Find all records in the join table and use go to related from the join table up to master, match found set and then show omitted. This will leave you with all master records that do not have a join record, and therefore notes. Link to comment Share on other sites More sharing options...
shredded Posted August 1, 2018 Author Share Posted August 1, 2018 (edited) While on the layout (Master), I'd like to have a field like Master::EmptyDataIDs, which is an sql that shows all __DataIDs related to Master, but with empty Notes field.

bcooney Posted August 2, 2018 Share Posted August 2, 2018 I never create a calc that has SQL in Define Fields. So, what you're saying is the the Data table has a field "Note" that can be empty. I would create a new field in Data MissingNoteInd = is empty ( Notefield) Then build a new relationship from the join table to Data MasterJoin::fK_dataId = __DataId and MasterJoin::ONE = MissingNoteInd ONE is a field we have in every table. It's very useful for filtering relationships. ONE = Let ( triggerOnChangesTo = Self ; 1 ), auto-entered calc, number, always evaluate Link to comment Share on other sites More sharing options...
Fitch Posted August 2, 2018 Share Posted August 2, 2018 I agree -- it's generally a Bad Idea to put SQL in calculated field definitions, or tooltips, conditional formatting or any other "static" elements. It will kill performance unless you are very very sure of what you're doing. Use SQL only for scripts. Link to comment Share on other sites More sharing options...
