restore db (restore database)

Type

Control Command

Purpose

The restore db command recreates a database. When processing reaches a restore db command, DataEase displays a series of prompts asking you to specify the drive on which the database should be restored and how you want to handle any errors that occur during the restore procedure.

The restore db command functions like selecting Application>>Utilities>>Restore.

Syntax

restore db .

Usage

When you backup an application using the backup db command, DataEase copies the application using a special format. The backup copy can only be used after it is restored using the DataEase restore db command or Application menu option.

When you backup and restore an application, all records that have been deleted since the last backup and restore operation are permanently erased.

LAN

On a LAN (Local Area Network), if another user is currently using any resource required by the restore db command, DataEase displays a Resource Conflict message. While this message is displayed, DataEase automatically tries to execute the command at brief intervals.

When the required resource becomes available, DataEase automatically resumes processing and executes the rest of the procedure.

Example

record entry "MEMBERS" .

run procedure "PRINT INVOICES" .

backup db .

restore db .

This script tells DataEase: (1) Display the MEMBERS form so the user can enter new member records, (2) when the user closes the MEMBERS form, run the PRINT INVOICES procedure, (3) make a backup copy of the current application, and (4) when the backup procedure is complete, begin the procedure to restore the application from the backup copy.
