The GetUpdateCommand method returns the SACommand object to be executed, so it may be useful for informational or troubleshooting
You can also use GetUpdateCommand as the basis of a modified command. For example, you might call GetUpdateCommand and modify
the CommandTimeout value, and then explicitly set that value on the SADataAdapter.
SQL statements are first generated when the application calls Update or GetUpdateCommand. After the SQL statement is first
generated, the application must explicitly call RefreshSchema if it changes the statement in any way. Otherwise, the GetUpdateCommand
will be still be using information from the previous statement, which might not be correct.
