sp_recompile

here is what i did:
create table Sajal (ID int)
insert Sajal values (1)
create procedure Sajal1 as
   insert Sajal values (1)
exec Sajal1
select * from Sajal   yields 1 row with value 1 in it.
alter table Sajal Add ModUser varchar(5) null
sp_recompile Sajal
gives the following message which is what one would expect:
Each stored procedure and trigger that uses table Sajal
will be recompiled the next time it is executed.
exec Sajal1
i was expecting that the above step would fail as now the table structure has been changed, since sp_recompile step would make sure that
the procedure is recompiled when invoked. however, the procedure excutes fine with a row in the table Sajal 1 null for ID and ModUser.
on the other hand when i execute the following:
create procedure Sajal1 as
insert Sajal values (1)
it complains that the number of columns in the table Sajal does not match with the number of values provided.

my question is that even after sp_recompile why does it not take into account the latest state of the objects that the procedure is referencing when one does exec Sajal1?
need help.
thanx.
sajal.

Because sp_recompile does not truly completely recompile the stored procedure, it is more a matter of "reoptimizing" it.  sp_recompile does cause new indexes, etc to be considered, but the procedure still doesn't realize changes to the actual table structure.  Only dropping and recreating the entire procedure does that.

I seem to recall that this is documented under the "alter table" command.
