Hello,

We are using PB 2019 R2 Build 2328 and have been dealing with an issue relating to execute stored procedure. 

We are using the nvo like below:

 

nvo_sqlcadb_log DBapplogs
DBapplogs = CREATE nvo_sqlcadb_applogs

DECLARE addlog procedure for SP_Add_Log 

@log = :ls_log

using DBapplogs.sqlcadb;

execute pbsp_update_log; ==> WE ARE GETTING NULL REFERENCE AT THIS LINE 

If DBapplogs.sqlcadb.SQLCode = -1 then 

  // show error 

end If 

The constructor() event of the "nvo_sqlcadb_log" looks like below:

sqlcaDB = create transaction

Then set sqlca parameters ... 

 

Since the issue "execute pbsp_update_log; ==> WE ARE GETTING NULL REFERENCE AT THIS LINE " happened , we've added a check for transaction "DBapplogs.sqlcadb" -> it showed this transaction is not valid . But it does not happen all time. ( this log is run all the time and every few days , the error "NULL REFERENCE AT "execute pbsp_update_log;" " happens )

Could you guys help me how to resolve this issue ? 

Thank you very much!
