Using Indexes to Bypass Locks

  • Article

One of the issues you'll face with SQL Server is blocking which is caused by other processes that are holding locks on objects.

Troubleshooting intermitten connectivity issues can be difficult. One approach is to repeatedly test connecting to SQL Server outside of an existing application in order to verify if a server-wide intermitten issue is occurring.
