function parameters

[=?Utf-8?B?cm9kY2hhcg==?=]

hey all,
i call out to a sql function to bind a couple of fields in my GridViewRow
and i'm using the same function just passing in different parms.

for example,
select dbo.getempinfo(int empid, int infotype)

i'm doing this because in the original function along the way it gets
another important calculated field i need somewhere else but its very closely
related.

is it ok to do something like this?
should i have made the parms clearer?
or should i just have made them 2 different functions?

thanks,
rodchar
