Hello,
I want to compare two tables (quite heavy) according to an id.
Source table and target table.
On the source table I have fields including an ID field that is unique, I load this ID value into an Easymorph table (source).
"select id as id_s from source_table".
Then in my target table I also have this field, which I load into another Easymorph table (traget).
"select id as id_t from target_table"
I've created a table derived from the source table and I'd like to retrieve the IDs from the target table that no longer exist in the source table?
Thanks for your help
