![]() SQL Server has its own set of timeouts, for example: command timeout (how long the app is willing to wait for a command to complete, including pulling the results down from SQL Server)īack in my classic ASP days, the defaults for these were 15 and 30 seconds respectively, I have no idea what they are by default in.connection timeout (how long the app is willing to wait to establish a connection to SQL Server).Well from an application point of view there are: Would someone provide a list of types of timeouts and/or deadlocks, it would help me to avoid these kind of cases when working on the application. In this application, it opened two connections, two separate transactions, where 1st transaction locked a resource, and the 2nd transaction try to access the same resource, but it hasn't close the first transaction. However, I also encounter a kind of deadlock where SQL Server doesn't detect it or timeout out. I also show rebuilding index timeout, which possible due to someone still have connection to table. I also saw SQL Server detect and throw a deadlock exception instead of timeout if two different applications lock on the same resource. In my experience, I easily run into timeout if I query a table that is exclusively locked. Each transaction can perform query or non-query SQL. Each connection can potentially have multiple transactions (please correct me if I am wrong). When working with SQL Server, there can be multiple application host accessing it, and each application can have one or multiple connections.
