A quick solution for SQL Server to establish a connection with the Server but errors occur during login.

if set nocount is on, the @ rowcount function is updated.When set nocount is on, the done_in_proc information of each statement in the stored procedure is not sent to the client. When you use a utility provided by Microsoft SQL server to execute a query) "Nn rows affected" is not displayed in the query results at the end ".If some statements contained in the stored procedure do not return much actual data,

, then the service account for each SQL instance should have a services broker endpoint. And all two SQL instances should have permissions to allow messages to be sent to each other's endpoints. The authorization and grant of the connection can be done through the following TSQL command set. Note that in the messaging infrastructure, there is one sender and the other is the receiver, as mentioned, if the

Sometimes, all you do to make the application run faster WorkMake some minor adjustments here or there. But the key lies in determining how to adjust it! Sooner or later, you will encounter this situation: SQLThe query cannot respond as you want. It either does not return data or takes a surprising amount of time. If it reduces the speed of enterprise applications, users must wait for a long time. Users want their applications to respond quickly and their reports can return analysis data instant

our sample solution, set the maximum Queue reader to 1 for two database queues. This can be increased if needed, for example, if data modifications are very high, you need to increase the cache refresh rate. Service Proxy Endpoint For our solution, the database runs on the same instance, so they all use the same service proxy endpoint to send and receive messages. However, if we want to host the database on a single instance, then the service account for each
