Coding ESQL to handle errors

You can use ESQL to recognize and handle the errors that are generated within your message flow nodes, and you can generate errors in particular situations if that is appropriate for the behavior of the message flow. You can also catch the errors generated by database interactions, and take whatever action is appropriate for your message flow, based on the codes that are returned by the database.

For a full discussion of the options that you can use to process errors in a message flow, see Handling errors in message flows. The following topics provide examples of what you can do:
