| Message: |
One of the sql script running multiple times a day from application end is performing slow in Production environment where as its performing very well in Non-Production environment where as the amount of data in tables is higher in Non-Production database and the statistics and execution plan of last executed script is available in cache.
One of the findings is that SQL Script executed doesn't hold its execution plan or statistics in cache, it gets immediately flushed out once the script completes its execution.
the other point is that when using option(recompile) in script, it completes execution with expected duration. |
