Will face any sharepoint issue after migrating SQL Server 2005 sp2 to sp4

We have one critical challenge to face on upgradation mechanism. Here I request you to have a change in Production server and need to upgrade from sql server 2005 sp2 to sp4 inorder to fix the bugs as per client request. After a while customer raised one concern regarding shall we face any issue on sharepoint services (due to application hosted on sharepoint services) after upgrading SQL server 2005 SP2 to SP4? currently database servers are sql server 2005 sp2.

It would be helpful to give any ideas on this issue ?

Thanks, Chaitu
