Connection error in sql server 2005 -

-

I have a problem, I run the application C # and I get an error

"A network-related or instance-specific error occurred when installing a connection to SQL Server.The server was not found or was not accessible. Verify that the name of the instance is correct and the SQL Server has a remote connection Is configured to allow. (Provider: SQL Network Int. Faces, Error: 26 - Error specifying server / instance)

What? Thanks

The error message says a lot: Make sure the example name is correct (if your SQL Server is using examples) and make sure your server is configured to allow remote connection .

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
