If youвЂ™re lacking in an automated job to manage statistics, I highly recommend checking out Ola HallengrenвЂ™s solution to this. Even with an nightly or weekly Agent Job managing stats, you may still find situations where you may need to perform an ad hoc stats rebuild. Thus, to find the cause of recompilation, its important to. Last, but certainly not least, you may also want to consider updating statistics if you do not already do this regularly. SQL Server can recompile individual statements within a procedure or the entire procedure.

(And if the content of TSQL is a multi-statement batch, or even if it's a single statement but includes the semicolon delimiter, you better make. If any check fails, then the T-SQL statement is compiled again or the corresponding batch will be compiled again and possibly a different query plan can be produced. If you want to make sure that the SQL supplied by the end user (shudder - but I'll bite my tongue and keep shut) is recompiled every time, you'll have to add the 'WITH RECOMPILE' option to the TSQL. Tuning the query may allow SQL to find a better road map for retrieving the data. When a T-SQL/Batch executes, before SQL Server begins executing the query, the database engine fist checks the validity and optimizes the query plan. If a query is poorly written then the execution plan will also be inefficient as it is relying on the poorly written query. Created using WITH RECOMPILE, the proc will build the plan on each execution without one, it will stick to a single plan (but will save time on recompilation itself).

In many cases, a poorly written query willВ cause significant performanceВ hits. SELECT FROM orders WHERE orderdate BETWEEN beginreport AND fromreport will be a full scan if the date range is large or an index scan if its small. However, if you are still seeing performance concerns, continue to review the execution plan and step through theВ stored procedure. With a little luck a quick recompile of the stored procedure will resolve the issue. Though this is only the first step to resolving potential performance issues, this should provide some insight as to where the resources are bottle-necking and give you a good idea of where to start.

Simply put, what you will be looking for when analyzing an execution plan are nodes that show a higher percentage of the overall cost of the query.
