In the above code, I sorted the result set in descending order of SummorizedLineTotal. The values of this column are grouped BY the Group BY clause and obtained BY using the aggregate function Sum for LineTotal. I sorted the results in descending order according to the values of SummorizedLineTotal. If you run this program, you can obtain the highest number of Line
statistics. You can look at the DMV sys.dm_os_wait_stats for these latch types. The most important thing here is that you are involved in the main memory competition, because their wait type name does not contain IO words.
Copy Code code as follows:
SELECT * from Sys.dm_os_wait_stats WHERE wait_type like ' pagelatch_% '
