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...

It depends.  You'd need to look at the available indexes and whether SQL uses them for the query.  So, look at the query plan and see what it "tells" you. ...

To reduce space usage in that db, you can specify SORT_IN_TEMPDB = ON in the index create.

Also, to save time, pre-allocate additional log space, if needed.  If you must get...

The CostKeyDeletes tables should be clustered on CostKey, not on ID.  It's best for it to match the original table's key.  You can keep the ID, if you want, just...

Why are you re-posting the same q?
