How to View the Query Execution Plan in Azure Data Studio (SQL Server) Estimated Query Plan. I found the problem but still don't understand the behavior. but as mentioned previously, when I call the stored procedure multiple times without SET STATISTICS XML ON or with SET STATISTICS XML OFF, I don't get the same behavior. I just need some guidance from anyone that would have witnessed this in the past.Ĭontinuing the troubleshooting I can now confirm that this happens when SET STATISTICS XML ON is set.Īnother observation, when running the stored procedure with the SET STATISTICS XML ON, every run just adds a set of 13 records from the previous run as if a table wasn't truncated before running. It might be something under the hood that the actual execution plan is doing on Azure. Plans with lower cost are expected to be more. The cost model used by the optimizer accounts for the IO, CPU, and network usage in the query. The query optimizer selects the execution plan with the lowest cost.
