What is the shortest, most efficient way to combine the following into one statement, if possible?

Select Word from Wordlist where location = w1 and number = 13
Select Word from Wordlist where location = w2 and number = 22
Select Word from Wordlist where location = w3 and number = 18
Select Word from Wordlist where location = w4 and number = 35
Select Word from Wordlist where location = w5 and number = 13
Select Word from Wordlist where location = w6 and number = 44
Select Word from Wordlist where location = w7 and number = 39
Select Word from Wordlist where location = w8 and number = 8

please note that number is not an identity column, and I cannot go by the identity column at all.
 
Thanks for your help!

Hi arthurh88,

two options come to mind ...

-- 1
Select Word from Wordlist where location = w1 and number = 13
UNION ALL
Select Word from Wordlist where location = w2 and number = 22
UNION ALL
Select Word from Wordlist where location = w3 and number = 18
UNION ALL
Select Word from Wordlist where location = w4 and number = 35
UNION ALL
Select Word from Wordlist where location = w5 and number = 13
UNION ALL
Select Word from Wordlist where location = w6 and number = 44
UNION ALL
Select Word from Wordlist where location = w7 and number = 39
UNION ALL
Select Word from Wordlist where location = w8 and number = 8

--2
Select Word from Wordlist where (location = w1 and number = 13)
or (location = w2 and number = 22)
or (location = w3 and number = 18)
or (location = w4 and number = 35)
or (location = w5 and number = 13)
or (location = w6 and number = 44)
or (location = w7 and number = 39)
or (location = w8 and number = 8)

hi there.  are you sure the OR statement is appropriate rather than an AND?

 I need to select all of those items and have 8 values returned.

I'm using an ASP.NET application and I need to grab all of those items from the dataserver, to dump the 8 values into a web page.

I need the output to be in the form of columns, W1 through W8.  I tried the UNION statement and it almost looked ok, except that the output was in one single column titled 'Word'.

I want the output to be a single row with Column Names W1, W2, W3, W4, W5, W6, W7, W8

arthurh88,

First of all, it would need to be an OR, if it was an AND all statements must be true ... and the "number" cannot be all of the values 'at once'.

Leaving that alone ... you want a single row returned with the 8 values as values.  Try ...
SELECT
(Select Word from Wordlist where location = w1 and number = 13) as w1,
(Select Word from Wordlist where location = w2 and number = 22) as w2,
(Select Word from Wordlist where location = w3 and number = 18) as w3,
(Select Word from Wordlist where location = w4 and number = 35) as w4,
(Select Word from Wordlist where location = w5 and number = 13) as w5,
(Select Word from Wordlist where location = w6 and number = 44) as w6,
(Select Word from Wordlist where location = w7 and number = 39) as w7,
(Select Word from Wordlist where location = w8 and number = 8)  as w8
