Why SQL Query Change the execution plan?

edited Jan 27, 2020 10:59AM in SQL Performance (MOSC) 2 commentsAnswered

I found query has changed plan and the query performance is deterioated

I have updated SQL Statistics still the plan is not getting changed by its own, and when i change the plan it automatically goes to previous one with bad performance

Howdy, Stranger!
