I have a table with a "SortID" column that is numbered using consecutive numbers. Whenever a row is deleted, it leaves a gap. Is there a way using pure SQL to update the rows with their row number? Something like this:
UPDATE tbl SET SortID={rowindex} ORDER BY SortID
(I realize this isn't valid SQL, that's why I'm asking for help)

WHEN 2 THEN 'Mike'

WHERE id IN (1,2,3)
My question is how...
I'd like to count and group rows by specific values. This seems fairly simple, but I can't seem to do it.
I have a table set up similar to this:
Table: Ratings
id pID uID rating
1 1 2 7

I'm not even sure how to even phrase this as it sounds weird conceptually, but I'll give it a try. Basically I'm looking for a way to create a query that is essentially a WHERE IN LIKE SELECT statement.
As an example, if I wanted to find all user records with a hotmail.com email address, I could do something like:
SELECT UserEmail

I was reading over the tutorial here: http://www.1keydata.com/sql/sql-running-totals.html and it all made sense until it suddenly got extremely ridiculously unbelievably complicated when it got to rank, median, running totals, etc. Can somebody explain in plain English how that query results in a running total? Thanks!

var cmd = new SqlCommand("INSERT ...")
cmd.ExecuteNonQuery();
}
}
I now want to shard the database and therefore need to choose the c...
