My understanding - that shouldn't ever happen.

If the data isn't changing, the data shouldn't be getting fragmented.  INSERT, UPDATE, and DELETE operations would cause fragmentation, SELECTs shouldn't.

I am pretty sure that SSMS doesn't include dtexec, but your coworker could confirm this by running dtexec outside of excel.  You listed the command that excel is trying to...

My preference is option 1 because then the command will write all the output PLUS the errors to the log file.  It also allows you to have 2 logs -...

What 3rd party database backup tool are you using and where is it writing the backups to?

I personally like having my backups available for me to restore to test systems...

NOTE - I do not use AG's nor have I configured them before.  I am just replying based on my interpretation of the errors you have.

If memory serves, the logins...

Does your coworker have dtexec installed?  If not, he can't run something doesn't exist on his system.

This is one of those "it depends" situations.  According to the Microsoft documentation (found here https://docs.microsoft.com/en-us/previous-versions/dotnet/framework/data/adonet/sql/managing-permissions-with-stored-procedures-in-sql-server), it states:

Step 1 - check the logs.

I would probably reach out to the server admins (and check the logs) to determine why starting the service as a user other than the...

As a random guess - I would say that in the presentation, entityID was an INT IDENTITY(1,1) and in your code, it doesn't seem to be an IDENTITY type.  So...

Possibly a dumb question but do you need those WHERE clauses?  If the data is the same, setting the value "10" to "10" is not going to hurt too badly...

I think I would approach this by using endnum+1 = LEAD(begnum,1).  This will help you determine if it is a gap or not; lets call this bitGAP.  You can use...

To confirm - it only happens on 1 of the 2 read-only secondary systems, correct?

If so, may not hurt to investigate any differences between the 2 systems.

Probably a shot in...

I was just reviewing what you had on your site and noticed a few mildly concerning things that may just need more clarification to me.

First, you say "Below is an...
