The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.

OT: FWiW, the following rewrite of that SQL UDF rids of the concat
symbols, the breaking down of the date components, those components
reconstituting the composite date using the concatenation, and the
intermediate variable for which BEGIN\END are required; returning the
numeric string of digits implicitly cast to the declared return-as data
type with just one reference to the input parameter in the expression
with just two scalar functions:
CREATE FUNCTION ROUTINES.DATETONUM ( REALDATE DATE )
RETURNS DECIMAL(8, 0)
LANGUAGE SQL
<<SNIP>>
RETURN REPLACE( CHAR( REALDATE, ISO ) , '-', '' ) ;
I do not _know_ which would be faster, but I would guess the latter.
