Table Function Examples

This section contains a number of additional examples that demonstrate some handy applications of using table functions to handle such tasks as performing extra tracing, establishing time limits, and using timed data refreshes. Each example takes advantage of the fact that table functions allow code to be written with a SELECT statement.
