  • How do you optimize a SQL query step by step?

    The Query Optimizer analyzes different ways the source tables can be accessed. It then selects the series of steps that return the results fastest while using fewer resources. The query tree is updated to record this exact series of steps. The final, optimized version of the query tree is called the execution plan.

  • How to improve query optimization in SQL Server?

    For your queries, you need to dparameterize them, but you do not need to cache them in all cases. If your queries tend to have a big cost (so compilation times are inconsequential) you will want to run them WITH OPTION RECOMPILE so SQL Server can adapt to the exact runtime values of all parameters.
