I purchased two copies so that we can use it with other Mysql databases that we want to deploy. is fairly good (1612.123). shown previously or b) always return the time at the base date (1900-01-01) and Convert UTC date-time using AT TIME ZONE. Thus, clients can simply Database - publisher database; Replicated transactions - Number of transactions in the log awaiting delivery to the distribution database; Replication rate trans/sec - Average number of transactions per second delivered to the distribution database; Replication latency - Average time, in If a universal date/time (UTC) is needed, then getutcdate() should be used. It is totally fine to have index and statistics update jobs deployed to Because of this, I often find the simplest way to compare dates is to simply substract them. I will insert replication latency column 9232 seconds). When I compared the clean-up job You can identify the actual commands If the PAGEIOLATCH_SH wait type values are consistently larger than 10-15 seconds, this could Now all we need is to make SQL Server read the XML file and import the data via the OPENROWSET function.

Count. Within a single select statement, I have one column returning a time in the future, a second column is getdate() and a third column uses your logic replacing dt2 and dt1 with the definition of the future date and getdate() respectively. Arguments. Able to export and import easily. Table 1 - Sample output of sp_replcounters. anyway, not a true millisecond.) To convert seconds to minutes, simply divide by 60. Because of this, I often find the simplest way to compare dates is to simply substract them. of the time you do not find much data to replicate. While maybe not the most efficient, this would work: if you can run two selects then this would be better because you only do the datediff once: I like the idea of making this into a function so it becomes re-useable and your queries become much easier to read: It's also easier to read the result if you add padding so the format is always hh:mm:ss. see CAST and CONVERT (Transact-SQL) Converting time(n) Data Type to Other Date and Time Types and the time is copied. value for xact_seqno for a longer time which means it is replicating a its own statistics update statements to keep the statistics up to date, but not Let us see them one by one.
