Top SQL Server Google Searches For July 2006

These are the top SQL Searches on this site for the month of July. I have left out searches that have nothing to do with SQL Server or programming. As you can see it has been a slow(er) month. And Google reports only searches that have been searched for more than once. For example if you have these 4 searches
insert triggers
insert trigger
insert triggers
insert trigger!

Then only insert triggers will show up since the other two were used only one time


Here are the results...

increase maximum row size in mssql
crystal report division by zero code
insert triggers
select sum where
select from
delete a null record


Let's talk about the last search (delete a null record ) a little bit
The code below will show you how exactly you delete a row with a NULL value. You can not use =NULL but you have to use IS NULL

CREATE TABLE #TestDeleteNull (id INT identity, SomeDate DATETIME)
INSERT #TestDeleteNull VALUES(GETDATE())
INSERT #TestDeleteNull VALUES(GETDATE())
INSERT #TestDeleteNull VALUES(NULL)


--Check what's in the table
SELECT * FROM #TestDeleteNull

--This won't work
DELETE #TestDeleteNull
WHERE SomeDate = NULL
--(0 row(s) affected)

--This is the way
DELETE #TestDeleteNull
WHERE SomeDate IS NULL
--(1 row(s) affected)

--Check again
SELECT * FROM #TestDeleteNull
