could not be started because there was an internal error in the network library. To determine the cause, check the error log for those errors that precede this error.SQL Server could not generate the FRUNCM thread. Review the SQL Server error log and the Windows event log for information about possible issues that may occur. Step three: Click on the MSSQLSERVER

An attractive service for RDS is to provide users with a slow log health report. Reports provide TOP20 SQL for users from different dimensions (total execution time, total execution times, total logical reads, total physical reads). RDS hopes to provide users with stable, fast service, while users can get more personalized optimization recommendations from RDS.This information is important, and users can ta

There are many causes for slow query speed of SQL Server databases. The following are common causes: 1. No index or no index is used (this is the most common problem of slow query and is a defect in programming) 2. Low I/O throughput, resulting in a bottleneck effect. 3. the query is not optimized because no computing

If the query is producing a large intermediate result set (perhaps a large join where most records be then discarded), yo U May is able to speed it up by changing parts of your query. Also, sometimes just adding the right index can solve issues like this. Look at the execution plan and see if there is any
