SIMPLE command to convert string to number? Not CAST or CONVERT.Ok, I hate to ask such a seemingly dumb question, but I've already spent far too much time on this. More that I would care to admit. In Sql server, how do I simply change a character into a number?????? In Oracle, it is: select to_number(20.55) from dual TO_NUMBER(20.55) ---------------- 20.55 And we are on with our lives. In sql server, using the Northwinds database: SELECT r.regionid, STR(r.regionid,7,2) as a_string, CONVERT(numeric, STR(r.regionid,7,2)) as a_number, cast ( STR(r.regionid) as int ) as cast_to_number FROM REGION R 1 1.00 1 1 2 2.00 2 2 3 3.00 3 3 4 4.00 4 4 SELECT r.regionid, STR(r.regionid,7,2) as a_string, CONVERT(numeric, STR(r.regionid,7,2) ) as a_number, cast (STR(r.regionid,7,2) as numeric ) as cast_to_number FROM REGION R 1 1.00 1 1 2 2.00 2 2 3 3.00 3 3 4 4.00 4 4 Str converts from number to string in one motion. Isn't there a simple function in Sql Server to convert from string to number? What is the secret? Thanks dba_***@yahoo.com wrote:

STR does something different and isn't needed in this case. -- David Portas, SQL Server MVP Whenever possible please post enough code to reproduce your problem. Including CREATE TABLE and INSERT statements usually helps. State what version of SQL Server you are using and specify the content of any error messages. SQL Server Books Online: http://msdn2.microsoft.com/library/ms130214(en-US,SQL.90).aspx -- Hmm. The question remains the same. (Not, why do I want to do that,
or, what's wrong with what you already have? Or, you shouldn't do that.) I want a SIMPLE sql server function like to_number(), or str() To convert a string to a number. Does a simple function exist in sql server to do the conversion? What is the secret?

It is called CAST(). It is has the
advantage of being completely ANSI SQL compliant. And it is easy to use. Of course, you could make your own FUNCTION if CAST() is too complex or difficult to use. I don't get the repeated question.

does not provide the function you want. Oracle chose to add a proprietary nonstandard function for this (which seems not to allow you to specify the specific number type, and there are many), and SQL Server uses the ANSI/ISO CAST function and requires a type. SELECT CAST('20.55' AS DECIMAL(4,2)) You can (if you know the consequences) use implicit conversion: SELECT 100.00*'20.55' SELECT 10000.0000*'20.55' SELECT 1E0*'20.55' If you aren't happy with what SQL offers as a language, there are plenty of other languages in the world of computing from which you can choose another.
