The solution is to tell the query analyzer how to sort by name. Here we need to use the keyword COLLATE Coliate as explained in the SQL Server books online:

You can use

To disable the default trail.
Black box tracking helps us diagnose database failures. We should also find it when searching sp_create_trace on MSDN.
Then we can create a similar stored procedure to quickly create a black box tracking, to help us diagnose some exceptions!

is more important to compare the number of reads between different query statements and to optimize the statements by reducing the number of reads.As for the pre-read scenario, we have previously analyzed that the data is preloaded by another thread when the T-SQL query statement is optimized.So this thread actually has a reference value when reading the data, and the data can be read from this reference to ensure that most of the data is useful, tha
