Solution 3

Select ID, Value1, Value2, (Value1+Value2) as Value from table where (Value1+Value2)>100

value is only an alias you can't apply condition with it

value is a reserved keyword in SQL so you cannot use as is, try the following:

SQL

Select ID, Value1, Value2, (Value1+Value2) as [Value] from table where (Value1+Value2)> 100

to see list of reserved keywords, see the following MSDN article:

While I agree that you should avoid reserved words, you cannot use a calculated field in a where clause, you must use the calculation.

The comment from __TR__ is correct.
