Updating current record oracle
Return to the SQL Worksheet and enter the command: Insert into departments (DEPARTMENT_ID, DEPARTMENT_NAME) Values (300, 'Research'); Click F9.NOTE: If you click F5, the detail is shown to the Script Output tab. As before you'll need to commit the changes to save them to the database. As in the above example, you can update data using the SQL Worksheet, using SQL commands, or you can use the data tab in the table definition and update individual rows. Once again you can update rows easily by using the Data tab interface.As you did in the previous exercise, click on a table in the Connections Navigator. Notice by clicking on a table different from the previous one worked on, the tab is replaced with the new selected table.

To edit a record, use the Edit method to copy the contents of the current record to the copy buffer.
If you don't use Edit first, an error occurs when you use Update or attempt to change a field's value.
If False (default), changes made by another user while the update is pending will cause the update to fail for those changes that are in conflict.
No error occurs, but the Batch Collision Count and Batch Collisions properties will indicate the number of conflicts and the rows affected by conflicts, respectively (ODBCDirect workspaces only).
This example would explain INSERT, UPDATE and DELETE operation on a table.
It should be noted that tables you are working on should have Primary Key set properly.
