Hi, what is the sql statement to convert a varchar to a number.  I'm trying to run a query that grabs all prices that are either less than, more than, or equal to a value but need to convert those values first.  Currently, the prices have commas in them such as 100,000 and I need them to return like 100000.  My database is ms sql server 2000.

I would do this:    cast(replace([price],',''') as int)

Remove the commas with replace, then use cast to cast the value to an integer.

If the the source column is a varchar with a comma in the text you have to remove the comma before converting it to an int datatype.  

SELECT CAST(REPLACE('100,000',',','') AS int)

You can convert it directly to money datatype:
SELECT CAST('100,000' AS money)

Or to money and then to int
SELECT CAST(CAST('100,000' AS money) AS int)

where column > convert(money,#b#)
in this example - #b# is your value such as 100,000
