Updating selfpopulatingcache example
I also provide examples that demonstrate how the various clauses work.
I created the examples in the Adventure Works2008 database on a local instance of SQL Server 2008.
In addition, the statement can include a WHERE clause, which determines what rows to modify, or a FROM clause, which identifies tables or views that provide values for the expressions defined in the SET clause.
In this article, I discuss how to use the UPDATE statement to modify data.
In most cases, when using Transact-SQL to modify data in a SQL Server database, you issue an UPDATE statement that changes specific values.
You can issue an UPDATE statement against a table or updateable view, as long as the statement modifies data in only one base table at a time.
Using remote templates makes the most sense for your development environment.
Note, however, that the data is slightly different in the Adventure Works database from what’s stored in the Adventure Works2008 database, so your results will be different than what is shown here. (Only the last example might need to be modified, which I’ll explain when we get to it.) To try out the examples in the article, you must first create the Sales Staff table, as shown in the following Transact-SQL code: Notice that I tag on a SELECT statement at the end of the code to retrieve the new content in the Sales Staff table.
Each assignment specifies a column name on the left side the assignment operator (=) and a literal value, an expression, or data from a subquery on the right side of the assignment operator.
Third, the WHERE clause specifies the rows that you want to update.

clause allows you to update data in one or more columns determined by a list of comma-separated assignments.
