Question

In a stored procedure I am selecting from a table using variables passed in. Then, I want to log what is selected. Is there any way to do this without using a temporary table or table variable?

The select statement:

Select userId, firstName, lastName, address
from myTable
where userName = @userName and password = @password

Then, I want to log the userId, firstName, lastName, and address that were selected. So:

Insert into loginLog...[results gotten above]

Note: I only want to log it if there is only one result returned. If more than one result is returned, I still want to select all the results, but I do not want to log it.

Use your select to populate local variables in the stored procedure. Log the results, then select the variable to return them to the caller:

declare
  @userID    int          ,
  @firstName varchar(255) ,
  @lastName  varchar(255) ,
  @address   varchar(255)   ,
  @rows      int

select @userID = userId ,
       @firstName = firstName ,
       @lastName  = lastName  ,
       @address   = address
from myTable
where ...

set @rows = @@rowcount

insert loginLog
select @userID , @firstName , @lastName , @address
where @rows > 0

select userID = @userID ,
       firstName  = @firstName ,
       lastName   = @lastName  ,
       address    = @address
where @rows > 0
