if something we do in informix has an analogous feature in MSSQL. We
can define a "row type" in informix, like so:
create row type name_1(fname char(20),lname char(20));
The when we create any table that includes a first and last name, we
do so using this row type like so:
create table sometable(name name_1, some column,...etc)
This allows us to set a standard for certain common fields and avoids
having different developers build the same type of field in more than
one way, different lengths, etc.
Is there a similar function in MSSQL server?sumGirl (emebohw@.netscape.net) writes:

In SQL 2000, no.
In SQL 2005, which currently is in beta, you can define structured types
in CLR languages like Visual Basic or C#, but it's not really the same
thing as the Informafix feature. I assume that in the Informix case you
can still say:
SELECT fname FROM sometable WHERE ...
and thus refer to the individual columns directly. With a CLR type in
SQL2005 you would have to say:
SELECT name.fname FROM sometable WHERE ...
