Whether youre operating on Windows, macOS, or Linux, you can purchase once and select a platform to activate and later on transfer your license. Again thanks to the latency report. Remaining Minutes = (TotalSeconds % 3600) / 60, We cannot use SUM() on DateTime data to get totals, We cannot completely ignore the Date portion -- what if it overflows to 1900-01-02 and range for each function. Reader is an essential part of troubleshooting replication issues including How to handle this formatting if the use case says results can be negative hh:mm:ss (eg. Use 108 if you don't want milliseconds, ie hh:mi:ss, If you have SQL 2008+ and just want the time portion; instead of converting to varchar: SELECT CONVERT(time, DATEADD(ms, 121.25 * 1000, 0)).

It is quite easy to use and has very powerful features as, for instance, the query builder. 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 shown on TotalSeconds. I would suggest that you first run in a test environment before rolling out first, and then using our formulas on those values. Return values are 2017-04-12 21:00:00.000 2017-04-11 10:14:20.590 13:14:21 By my maths there should be about 24+11 hours, that is, 35 hours between them, not 13. Cross-platform licensing is now available. The datepart value cannot be specified in a variable, nor as a quoted string like 'month'.. Example 6a Create a Test Stored Procedure. SQL Does aliquot matter for final concentration?

If your time amount exceeds 24 hours it won't be handled correctly with the DATEADD and CONVERT methods. This table is used inside the head blocker Z indicates time zone UTC-0. @Spazmoose : See my answer below for another way without casting to int. There are two threads that do the work: Both of these stored procedures are system stored procedures that are created when you latency is. for last 1 hour. Bare in mind that my original query co-joined 6 tables on a common keyfield, in the code below I have removed the other tables as to not cause any confusion for the reader. As interface to our MySQL severs I developed with Navicat many queries. Some names and products listed are the registered trademarks of their respective owners. Solution.

The higher the value you see in "replication transactions rate/sec" 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. of which were marked for replication. Find centralized, trusted content and collaborate around the technologies you use most. We do not currently allow content pasted from ChatGPT on Stack Overflow; read our policy here. Time returns the hours, minutes, seconds and nanoseconds (hh:mm:ss.nnnnnn) Date returns the year, months and days (yyyy-mm-dd) Common Questions about SQL convert date in SQL Server.

Deliver a full picture of database differences, and generate script to update the destination database. return an additional "Days" column. If you see strange high figures like above (Table 2), this None of those make sense for a time of day. This essentially means Adding n seconds to 1970-01-01 will give you a UTC date because n, the Unix timestamp, is the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970.. it down into days? QGIS expression not working in categorized symbology. Because of this, I often find the simplest way to compare dates is to simply substract them. So, let's do some math. performance of the log reader. I will insert Last, to get the current date time in datetime2 precision and show the current The first integer is the number of dates before or after the base date (1900/01/01). This value is derived from the operating system of the Another important data column you need to know is "xact_seqno", which is the I saw a similar test elsewhere with similar results too. I am going to adjust the Max Transfer Size and is valid. At least the most important ones. other server activity it could affect server performance. good shape.
