query rollback policies in sql server 2008 r2

Question

I have a query that consists of some inserts and updates, something like this

   Insert Into #TempTable (...) Select top (1000) * from T where ....

   Update T2 Set c1=...,c2=... where w1

   Update T2 Set c1=...,c2=... where w2

   Update T2 Set c1=...,c2=... where w2

I run this query from a C# App. Each part of this query could be got time out because of heavy load on server, I wanna know that if one part of query got time out (for example second update), all prior queries (Insert and first update) would be rollback by Sql Server engine?

Answer 1

After opening the SqlConnection at your code, do SqlCommand.CommandTimeout = 0; , This will prevent timeout errors causing by .net C# side.

If you are creating SqlDataAdapter by using the sqlcommand you set the timeout to 0, make sure that: SqlDataAdapter.SelectCommand.CommandTimeout=0 after creation by debugging.
