Query times out when executed from web, but super-fast when executed from SSMS

Question

I\'m trying to debug the source of a SQL timeout in a web application that I maintain. I have the source code of the C# code behind, so I know exactly what code is running.

Answer 1

I had the same problem and it was fixed by executing procedure "WITH RECOMPILE". You can also try using parameter sniffing. My issue was related to SQL cache.
