, the thread pool of SQL Server is enabled by using the number of threads 45, in a certain order to access your table. If you lock table A and then lock table B, you must lock them in this order in all stored procedures. If you (inadvertently) lock table B in a stored procedure, and then lock Table A, this could result in a deadlock. Deadlocks are hard to find if the lock sequence is not designed in advance

If you want to query Index Server through SQL Server, you must use the OPENQUERY function. The syntax structure is as follows. OPENQUERY (pai_server, 'query ') The linked_server parameter indicates the connection name. The query parameter is the query to be performed. It is transmitted to the OPENQUERY function in the form of a string. This function returns a vir

. This means fewer rows per page, so more I/O is needed to see the same number of rows. The result may be that speeding up a query may slow down other queries. Consider the impact on various parts of the system, rather than just the specific queries that are being used at some point. 　　3. With With is very simple-it just tells SQL Server to provide one or more of the following options. 　　4, Pad_index This o
