title: Getting around the lack of IsNumeric() function in SQL CE?
body: <p>SQL Server CE (3.5) doesn't appear to support the <code>IsNumeric</code> function.  What are some alternatives to achieve the same functionality?  Specifically, how would you test whether a <code>CAST</code> from a string to a <code>DECIMAL</code> datatype will succeed in SQLCE without <code>IsNumeric</code>?</p>
