Hi, perhaps you can check the console or logs for error messages when the datalist is empty. There might be an exception which will give a clue as to what is happening.

Dear Anders Thanks for your reply. I check Logs of joget, it shows : ERROR 14 May 2018 10:48:53 org.joget.plugin.enterprise.JdbcDataListBinder - java.sql.SQLSyntaxErrorException: ORA-00904: "TEMP"."TRAVELAPPLICATIONREF": invalid identifier java.sql.SQLSyntaxErrorException: ORA-00904: "TEMP"."TRAVELAPPLICATIONREF": invalid identifier; In my form , there is a field "Travelapplicationref" but in table , it named "C_travelapplicationref". My Joget is V5 and use Oracle XE 11.2.0 as database. I tried to remove condition to let SQL simply like : select * from app_fd_SHAZI18A1_Home_App. the same error happened. Could you help?

Hi Joget Workflow creates the database columns prefix with "c_", example "c_myField". Do download the free app Simple Leave & Vacation (https://marketplace.joget.org/jw/web/userview/mp/mpp/_/vad?id=APP_leave-v1) from Joget Marketplace. The datalists in this app uses JDBC which you can view and learn the SQL usage (However the SQL was designed for MySQL database type).

Resolved.

I just create a new datalist , all are same as old one. But it can work

So still don't know what happen for the old one ....
