IS it possible to use the 'Where' clause in SQL to only show a field containing only letters & Numbers?

Question

I want to be able to select only the field where a certain field contains both letters and numbers. for example:

Select [field1], [field2] 

from [db1].[tabl

What you would want to do is SQL-based regexp matching. Check this out: http://msdn.microsoft.com/en-us/magazine/cc163473.aspx

Quotes:

"Although T-SQL is extremely powerful for most data processing, it provides little support for text analysis or manipulation. Attempting to perform any sophisticated text analysis using the built-in string functions results in massively large functions and stored procedures that are difficult to debug and maintain."

And:

"However there's SQLCLR, a CLR user-defined function (UDF) that lets you create an efficient and less error-prone set of functions using the Microsoft® .NET Framework."

Then you get code examples. Isn't Microsoft great? :D
