Function management
8. Summary

Instruction

Congratulations! You've just completed function management. It's time to quickly review what we've learned in this part:

  • The CREATE FUNCTION statement is used to create a new function.
  • The CREATE OR REPLACE FUNCTION command allows us to change the definition of a function. If the specified function doesn't exist, the command creates it. If the function exists, it is replaced.
  • To rename a function, you can use the ALTER FUNCTION ... RENAME TO command.
  • The DROP command with the IF EXISTS option can be used to remove a function that is no longer needed.

We hope you enjoyed this part and learned something new about function management. See you in the last part!
