sql - Query column nullability of the resulting rowset of a tsql SELECT statement? -


consider following pseudo-tsql

table {    field1 int,    field2 int null }  table b {    field1 int,    field3 int }   create procedure sp1     select a.field1, a.field2, b.field3     inner join b on a.field1 = b.field1 

is possible query procedure sp1 if resulting columns can null or not? seems dataset generator can pull off right?

can done in tsql? other means?


desired output:

field1 int, field2 int null, field3 int 

or:

field1, field2 nullable, field3 

(the first better)


thanks!

the dataset generator set fmtonly set option on. causes empty result sets returned client, instead of running queries. client data access technologies (e.g. ado.net, sql native client, etc) have ways of interrogating result set objects (even empty ones) , determining schema information them.

i can't think of way consume information t-sql though. way of grabbing result set stored procedure insert...exec, in case, have have table defined.
