64KB and 32KB cluster size for log drives and tempdb - Hi, I was told that sometimes log and tempdb drives benefit from 32KB cluster size as opposed the traditional 64KB. How can I check this theory for a specific system? I guess different database servers have different write patterns. How do I find out what write sizes a particular server uses the most and if […] |
Timeout while trying to add database to availability group - Hello experts, I'm trying to learn what network access is being blocked when I get the timeout error below. It happens after I click Connect in the Add Database to Availability Group wizard. I have sometimes gotten around this by using T-SQL to add the db, but I want to finally understand how to fix […] |
Using the Database Migration Assistant - Getting questionable results. - Hello, Firstly, apologies if I have posted in the wrong spot, I could not find a 'Migration' forum here. Happy to move it elsewhere if need be. I am using the Database Migration Assistant to recommend an Azure SQL Managed Instance SKU for an on-premises SQL Server 2017 instance. I ran the assessment over 3-4 […] |
Windows 11 & sudden SSMS sorting nuisance - When I was still in Windows 10, I'd open up SSMS (version 18) and go to Object Explorer Details, where I would see the folders System Databases and Database Snapshots up at top and all the individual database names listed in alphabetically order (unless I sorted otherwise). Now that I've upgraded to Windows 11, something […] |

Why am I getting a "Incorrect syntax near '@tblName' error message? - I'm working on a SQL script to delete all old tables starting with the name of "Old_". I'm testing in my test database, but it raises errors. However, if I use the PRINT statement, everything is fine. I don't get what's wrong. I'm following Microsoft's Learn page on sp_executesql, and as far as I know, […] |
How to calculate potential IO benefits of changes - I work on a multi terabyte warehouse database application which typically ingests between 130 and 180 million rows of data per day and processes into a data mart for them for consumption into a Tableau report.

What do I do about OBJ files, when I try to commit to a Git repository? - Today I was trying to store an SSRS project into a Git repository. (The SSRS project was written by a vendor.) I wanted to put it into Git so that if I needed to revert to an older version, I could do that more easily. I was going to use GitHub to store the repo […] |

Checking flag sometimes false\positive result - I have this script checking a SQL table looking for a result of True in a table. 99% of the times it works as designed, but on certain occasions it does not. I check this with a scheduler every 5 minutes. It sometimes produces a result of true in which hasn't been set to that […] |
extract data from all servers and dump it into a table - I have 5 servers in the servers table . The code is not looping through all servers. Its only going to the ABC server 5 times and capturing data from ABC server 5 times. $Servers = Invoke-Sqlcmd -Query "SELECT ServerName FROM dbo.Servers" -ServerInstance "ABC" -Database "DB" foreach ($Server in $Servers) { $ServerName = $Server.ServerName If […] |
