#GeneralInterest -: Hi all ,
I have one scenario, Let say i have one table Employee in this table, i have 3 columns RowId (Primary Key ),EmpId(int) and EmpName(text),EmpId and EmpName should be unique and from UI if two users are trying to insert same value at same time, then these entry should go as overwrite instead of creating two separate entries in database, I have tried using Unique Key constraint but if we are trying to insert same record which is exist in database that time write to database node is failing and i am getting “Unique key constraint violation error”, for work around i am checking record is exist in database or not, if yes then updating existing record on Write to Database node and also using unique key constraint ,but any other way to do this because two users are running flow simultaneously with same value so whose entry will go first that we are not sure?
Kindly suggest how to handle?

You can use the "Query Database" smart service to write to DB. It lets you define whether it stops on errors or not. I use this to implement robust locking for records. See
