Conclusion

In SQL*Plus 23ai and SQLcl 22.4, the ARGUMENT command provides an advanced way to manage script arguments. For database experts, its ability to manage prompts, secure inputs, default settings, and integrations with DEFINE and VARIABLE commands makes it an essential tool. This functionality transforms the way Oracle scripting is done by enabling developers to write interactive and flexible scripts.
