| SQL input parameters are defaulting to nvarchar causing full table scans - When our applications are submitting SQL via ADO.Net, with input parameters, the parameter definitions are defaulting to nvarchar.

| Distributed Availability group - Is there a guideline or does anyone have any step by step process on removing Distributed Availability group between 2 servers properly? I am trying to beak it a part because the secondary server (forwarder) is old and ready to be decommissioned. This is how servers are setup: DAG between SQL1P (forwarder) and SQL2P (primary) […] |

| What is reliable method to find all unresolved references? - I need to find all stored procedures that point to a table, function, a database that does not exist. I am using sys.sql_expression_dependencies built-in view for this. There are two problems with it. First, in some cases referenced object in this view is just an alias; and second, it happen to be a part of […] |
| Data type Date - Previously we had some issues with deadlocks caused by transaction that happen so fast that the current timestamp column is not accurate enough to prevent a collision. To prevent such an occurrence we need to change the data type used by the timestamp column in order to make it more precise, both for existing tables […] |

| Upgrade SQL 2017 to 2019 - Hi I guess this question has been asked before - but I failed to find best practice recommendation. We have a SQL Server 2017 and need to upgrade to 2019. The plan is to just install the 2019 instance on same physical SQL Server as a second instance. Then move databases from the 2017 […] |
| PowerShell - ItemArray - Can anyone please explain to me what .ItemArray does in PowerShell? I read the doco but I don't understand it. I have an array of SQL instances using mixed names i.e. server.domain, server.domain\sqlinstance, server.domain\sqlinstance, portnumber I used a foreach loop to pass the items in the array to an Invoke-Sqlcmd statement.

| Restore - what happens after 100% - Just curious. I restore databases very often as I am a developer. Some of them has a size, that means that it takes some time.

| AWS Reserved Instance for Old Servers - We have a couple of SQL server instances(i2 and r3) from about 5 years ago. We are looking to reserve the instances now without upgrading to new, but I don't see any of these instances listed in the "Reserved Instance" section.
