title: SQL query runs faster than stored procedure
body: <p>I have a stored procedure which I modified recently on my production server and it started performing poorly but when I run the query independently it runs fine. The difference in timing is a lot i.e comparing 5 secs to 10 mins is alarming. </p>
  
  <p>I read this post <a href="https://stackoverflow.com/questions/440944/sql-server-query-fast-but-slow-from-procedure">SQL Server: Query fast, but slow from procedure</a> and tried resolving my issue with all the possible solutions but still the stored proc does not work it is having the same difference in timings. </p>
  
  <p>Can anyone let me know what should I change so that my stored proc runs at least as fast as the query? I am a bit surprised by this behavior of SQL Server</p>
  
  <p>Good Plan </p>
