Salah satu pertanyaan yang sering
diajukan adalah bagaimana cara melakukan backup dan restore database sql server
menggunakan coding (vb.net). hal ini dilakukan untuk memudahkan user dalam
penggunaan aplikasi tanpa harus "menyentuh" server. Langkah awal
adalah membuat form seperti gambar di bawah ini :
Langkah selanjutnya adalah membuat Coding sebagai berikut :
Imports System.Data.SqlClient
'imports Microsoft.SqlServer
Public Class
backuprestore
Dim con,
con1 As SqlConnection
Dim cmd As SqlCommand
Dim dread As SqlDataReader
Private Sub backuprestore_Load(ByVal
sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
server(".")
server(".\sqlexpress")
End Sub
Sub server(ByVal str As String)
con = New
SqlConnection("Data Source=" &
str & ";Database=Master;integrated
security=SSPI;")
con.Open()
cmd = New
SqlCommand("select * from sysservers where srvproduct='SQL Server'",
con)
dread = cmd.ExecuteReader
While
dread.Read
cmbserver.Items.Add(dread(2))
End While
dread.Close()
End Sub
Sub
connection()
con = New
SqlConnection("Data Source=" &
Trim(cmbserver.Text) & ";Database=Master;integrated
security=SSPI;")
con.Open()
cmbdatabase.Items.Clear()
cmd = New
SqlCommand("select * from sysdatabases",
con)
dread = cmd.ExecuteReader
While
dread.Read
cmbdatabase.Items.Add(dread(0))
End While
dread.Close()
End Sub
Private Sub cmbserver_SelectedIndexChanged(ByVal sender As
System.Object, ByVal e As
System.EventArgs) Handles
cmbserver.SelectedIndexChanged
connection()
End Sub
Sub query(ByVal que As String)
On Error Resume Next
cmd = New
SqlCommand(que, con)
cmd.ExecuteNonQuery()
End Sub
Private Sub Timer1_Tick(ByVal
sender As System.Object, ByVal e As System.EventArgs)
Handles Timer1.Tick
If
ProgressBar1.Value = 100 Then
Timer1.Enabled = False
ProgressBar1.Visible = False
MsgBox("Successfully
Done")
Else
ProgressBar1.Value =
ProgressBar1.Value + 5
End If
End Sub
Sub blank(ByVal str As String)
If
cmbserver.Text = "" Or cmbdatabase.Text = ""
Then
MsgBox("Server
Name & Database Blank Field")
Exit
Sub
Else
If
str = "backup" Then
SaveFileDialog1.FileName =
CmbDatabase.Text
SaveFileDialog1.ShowDialog()
Timer1.Enabled = True
ProgressBar1.Visible = True
Dim
s As String
s = SaveFileDialog1.FileName
query("backup
database " & CmbDatabase.Text & "
to disk='" & s & "'")
ElseIf
str = "restore" Then
OpenFileDialog1.ShowDialog()
Timer1.Enabled = True
ProgressBar1.Visible = True
query("RESTORE
DATABASE " & CmbDatabase.Text & "
FROM disk='" & OpenFileDialog1.FileName & "'")
End
If
End If
End Sub
Private Sub cmbbackup_Click(ByVal
sender As System.Object, ByVal e As
System.EventArgs) Handles CmdBackup.Click
blank("backup")
End Sub
Private Sub cmdrestore_Click(ByVal
sender As System.Object, ByVal e As
System.EventArgs) Handles cmdrestore.Click
blank("restore")
End Sub
End Class
