Title

Self Join Relationship

Post

     Ugh, for some reason this isn't working.  Here's what I have

     Battery_data table

     - has fields "cell number" and "volts". "cell number" should count up from 1 to inf in whole steps of 1, i.e. 1, 2, 3, etc as long as they are related to the same parent table (test_report).  So if they have the same fk, they should count up.

     - Have a self join relationship for this table, with fk_testreportid = fk_testreportid being the relationship criteria, 2nd table occurrence called battery.autocellnumber

     - "cell number" has auto-entered-calculation with the formula "Max ( battery.autocellnumber::cell number ) + 1"

     It's inserting "1" every time as records are created in my portal and can't figure out why.

      

     Any thoughts?
