![]() ![]() DEFAULT can be written to specify resetting the parameter to its default value (that is, whatever value it would have had if no SET had been executed in the current session). st.formsubmitbutton can have a callback associated with it. Values can be specified as string constants, identifiers, numbers, or comma-separated lists of these, as appropriate for the particular parameter. Widgets inside a form can have their values be accessed and set via the Session State API. Available parameters are documented in Chapter 20 and below. ![]() Issuing this outside of a transaction block emits a warning and otherwise has no effect. After COMMIT or ROLLBACK, the session-level setting takes effect again. Specifies that the command takes effect for only the current transaction. (This is the default if neither SESSION nor LOCAL appears.) LOCAL Specifies that the command takes effect for the current session. However, a regular SET command overrides any surrounding function's SET option its effects will persist unless rolled back. This allows SET LOCAL to be used for dynamic or repeated changes of a parameter within a function, while still having the convenience of using the SET option to save and restore the caller's value. If SET LOCAL is used within a function that has a SET option for the same variable (see CREATE FUNCTION), the effects of the SET LOCAL command disappear at function exit that is, the value in effect when the function was called is restored anyway. The effects of SET or SET LOCAL are also canceled by rolling back to a savepoint that is earlier than the command. A special case is SET followed by SET LOCAL within a single transaction: the SET LOCAL value will be seen until the end of the transaction, but afterwards (if the transaction is committed) the SET value will take effect. The effects of SET LOCAL last only till the end of the current transaction, whether committed or not. Once the surrounding transaction is committed, the effects will persist until the end of the session, unless overridden by another SET. I also wrote some simple bat scripts that I use to easily copy the current session files, restore, and make some backups. Relaunch and click 'Restore' when prompted. If SET (or equivalently SET SESSION) is issued within a transaction that is later aborted, the effects of the SET command disappear when the transaction is rolled back. So in summary, after grabbing the right files, the steps should be: Kill Chrome. There are also parameters that cannot be changed after server or session start.) SET only affects the value used by the current session. (Some parameters can only be changed by superusers and users who have been granted SET privilege on that parameter. The Reason tab shows the reason for the guest OS file restore that. Many of the run-time parameters listed in Chapter 20 can be changed on-the-fly with SET. The Statistics tab shows detailed information about the files restored during the session. Here are few examples: new Pixo.The SET command changes run-time configuration parameters. ![]() ![]() only saved images, or only unsaved) or remove it completely. You can define which session types to be restored (e.g. The great thing about Session Restore is the fact that it is fully configurable. This works for both saved and unsaved images. Just as if you didn’t quit your previous session. Pixo now automatically restores the previous session of an image, allowing you to get back in history (Undo), change settings, update text, remove existing stickers, anything. Did you ever close the Pixo Editor by accident, and all your edits gone away? Or did you ever quickly hit Save and few seconds later wanted to undo a change, but loading the exported image simply started a new session? Well, we are happy to tell you that this is now over!įew days ago we released a great feature of the editor – Session Restore. ![]()
