Go Up to MySQL object wizards

The MySQL Functions Wizard lets you build and submit a CREATE FUNCTION declaration, specifying a return type and the owning library.

Note: Functions must be written in C or C++, your operating system must support dynamic loading, and you must have compiled mysqld dynamically (not statically).

To create a new function using a wizard:

  1. Open a creation wizard for a function. For details, see Opening an Object Wizard.
  2. Use the following topics as a guide to setting properties and performing tasks as you pass through the wizard panels:
  3. Finally, use the Execute button to create the object.
