This video is part 4 of a 4 part section of videos on the Data Manipulation Language (DML) UPDATE STATEMENT. This video takes the UPDATE STATEMENT to the next level.

  • T-SQL Proprietary Code
  • FROM Clause and the UPDATE Statement
  • Origin of the FROM Clause

  • Real world examples of how and why to utilize the FROM clause
  • Common Errors in real world uses of SELECT and FROM statements and how to rectify those errors

  • subquery instead.
  • Examples show on what is ANSI compliant syntax and what is T-SQL proprietary syntax
  • Proper UPDATE Statement and SET Command syntax
  • Real World examples of proper syntax and bad syntax when writing UPDATES and JOINS
Scott does a wonderful job of showing us how to utilize the UPDATE statement with a JOIN syntax.This video however does require an extensive amount of knowledge towards JOIN statements to followthis.
