SQL Server Stored Proc results to Table

Hello.  I have SQL stored proc that returns 5 columns.  I want to execute that SP and place the data into a temp table, but I only want to return 3 of the 5 columns.  Logically I assumed I could do this by defining my temp table with the 3 fields I need, then run an INSERT INTO also specifying the 3 fields.  

Problem is when I run it I receive an error message "Column name or number of supplied values does not match table definition".

Sample code is below.  Any way I can execute the SP and only return a, b, and c into the temp table?

Thanks.
Create Table #TempTable ([a] varchar (20) null,
			 [b] varchar (20) null,
			 [c] varchar (20) null)
						 
Insert Into #TempTable  ([a], [b], [c])

Execute mystoredproc -- this sp returns fields a,b,c,d,e

If I am not mistaken, you will need to insert all the columns and then just drop the ones you don't want later OR just have two tables. One to get initial results and the other to store the three columns you want if going to hold other data. If the table is just holding the stored procedure data, it is probably makes sense to have all the columns and just select a, b, c only or as I said alter table and drop the extraneous columns.

mwvisa1, thanks for your comments.  The challenge is that the number of fields in the SP (mystoredproc) is continually changing.  We have numerous other queries/sp's that rely on [mystoredproc] and we would like a way to be able to add fields to [mystoredproc] without having to also update all the many other queries/sp's that use it.  Hope this makes sense.

One option if these are singular values is to add OUTPUT parameters. You can have @a, @b, and @c. Another option is to have a single XML parameter that represents the output you want in XML format. You can take that and parse to your table. I know table-valued parameters were added to SQL 2008, but could not remember if OUTPUT was allowed--it is not, but found an interesting option in this thread: http://www.sqlservercentral.com/Forums/Topic627916-145-1.aspx

Suggestion is to create a self referencing linked server, so that you can use OPENQUERY which gives you the ability to then select what columns you want. If your stored procedures all use a common nomenclature for the first three columns this may be a good workaround.
