(Nested) loop joins are a concern, particularly if SQL doesn't properly estimate the number of...

If you select the query code, right-click on it, and then select "Display Estimated Execution Plan", you should see any recommended index

More technically, you need permissions for whatever account SQL Server is running under.

It doesn't.  It's the "+=" that causes the msgs to "accumulate" (concatenate).

For example, if you do this:

DECLARE @msg varchar(max);

DECLARE...

You can check for NULL as well in either format:

DECLARE @LATEST_DATE date;

SELECT @LATEST_DATE = ISNULL(MAX(MY_DATE), ...) FROM DBO.TABLE

I think you'll have to check for that yourself, maybe something like this:

SELECT CASE WHEN TRY_CONVERT(DECIMAL(9,6),'6.125') <> TRY_CONVERT(DECIMAL(5,2),'6.125') THEN 'Loss of precision error' ELSE 'Good' END

SELECT CASE...

Either below; the first  is more typical:

DECLARE @LATEST_DATE DATE;

SELECT @LATEST_DATE = MAX(MY_DATE) FROM DBO.TABLE

--or:

SET @LATEST_DATE = (SELECT MAX(MY_DATE) FROM DBO.TABLE);

It depends.  If the unused space is significant and is embedded in pages that are being read, i.e. contain live data, then it could slow down access (somewhat) because more...

(1) If you have a lot of dbs, make the $IDENTITY column a primary key in the table, so you have a seek instead of a scan

(2) DBCC CHECKDB can...

1. No
2. No

And, that is the correct method for moving dbs to a new drive.

IF you're on SQL 2022, you can add "IGNORE NULLS" to the LAG function.

Otherwise you can use an OUTER APPLY with a SELECT TOP (1).  For example:

SELECT...

First, you need to correct the query to use the alias in the UPDATE, not the original table name.  Other things to consider if still having problems:

(1) How large is...

AFTER UPDATE is the more current syntax, so I would go with that.

I would also (1) take advantage of the UPDATE() function and (2) allow the trigger to properly set...
