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.

updating current record oracle-79

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.

" If Msg Box(str Prompt, vb Yes No) = vb Yes Then _ . str First Name = Trim(Input Box( _ "Enter first name:")) str Last Name = Trim(Input Box( _ "Enter last name:")) ' Proceed only if the user actually entered something ' for both the first and last names. Last Name ' Delete new record because this is a demonstration.

" & vb Cr & _ "Do you want the program to force " & _ vb Cr & "an update using the local data? Open Recordset("Employees", db Open Dynaset) ' Get data from the user. Print _ "You must input a string for first and last name!

Last Name = "Sornsin" ' Show contents of buffer and get user input. Last Name ' Delete new data because this is a demonstration. It is also required that a table ' with a primary key is used. Open Recordset( _ "SELECT * FROM roysched", db Open Dynaset, 0, _ db Optimistic Batch) With rst Temp ' Modify data in local recordset. Add Name rst Employees, str First Name, str Last Name ' Show the newly added data.

Cancel Update Msg Box "No new record added." End If . Close End Sub Sub Batch X() Dim wrk Main As Workspace Dim con Main As Connection Dim rst Temp As Recordset Dim int Loop As Integer Dim str Prompt As String Set wrk Main = Create Workspace("ODBCWorkspace", _ "admin", "", db Use ODBC) ' This Default Cursor Driver setting is required for ' batch updating.

If str First Name "" Then ' Call the function that adds the record.
