If you only want to compare based on the leading numeric characters (0-9 only), you can do this (I prefer PATINDEX to CHARINDEX in this case, as it handles all...

Is there a sql statement that could turn it into this?
Yes, look at PIVOT as well.

When the table is truncated the table is reseeded with values back to 1 again.
Technically, the table is set back so that the next row inserted gets the initial...

The "traditional way" was to do an UPDATE then an INSERT, each time doing a join from the new data to the existing table data to verify that they key...

You really should use the sys.* views to generate the code, rather than using the INFORMATION_SCHEMA views, because, according to Books Online:
"
Do not use INFORMATION_SCHEMA views to determine the schema...

written an SP that uses a table that doesn't exist
I think your best chance is to try the following DMVs:
sys.dm_sql_referenced_entities
sys.dm_sql_referencing_entities
Other than that, I don't of anything else within SQL...

wonder why this isn't tracked in the catalog.
I suspect it was to keep down overhead.
MS could theoretically have logged tons of things like that in SQL, which would be...

Typically non-clustered indexes are not needed here, since you specify columnA in (virtually) all queries, in a reasonably narrow range.
Of course sometimes they do help specific queries, so you could...

Why not just add a column in the table for the "old" id column?
It's only 4 more bytes, and you'd then be able to reference that column in...

Cluster by columnA (date/datetime) only.
That will keep the clustering key short but still restrict the number of rows a query must read and evaluate.
Sometimes additional column(s) are appropriate for the...

I wouldn't expect it to change the space available at all, so I'm guessing other activity reduced the space available in the table.
Just to be sure, you did use an...

I'm not horribly against the idea of dropping the FK, but maybe I'm not fully understanding the advantage of doing so. How does deleting the parent records first improve performance?
It's...

Then why even have the constraint at all then. If all inserts/updates and deletes are done under controlled access methods (ie SPs) and ad-hoc access to the database is not...

Might not be a good idea if inserts are expected while also doing the deletes.
Perhaps, if you really normally do INSERTs that would violate the constraint. Hopefully that's extremely...
