How do I simplfy this Stored Procedure?

Question

How do I simplify this Stored Procedure? I only want the name, birthdate and gender to pull once. Also, the individual SQL Statements use some of the same records. Is there a way to use the same field, but have it look at different criteria?

USE [OHM]
GO

05/28/2014    10:07:50 ******/

Answer 1

Given the comments, yes, if you want to remove the fields and tEmployee table from the select statements, you can do this, and then replace joins to that table with a join to the @Employee parameter. Anywhere that Joined to tEmployee.ID, use @Employee instead.
