在MySql数据库中插入DataGrid值
我想将我在datagrid视图中输入的值添加到mysql数据库中 要删除当前选定的ID,我使用此代码在MySql数据库中插入DataGrid值,mysql,vb.net,datagridview,Mysql,Vb.net,Datagridview,我想将我在datagrid视图中输入的值添加到mysql数据库中 要删除当前选定的ID,我使用此代码 Dim reader As MySqlDataReader Try SqlConn.Open() Dim query As String query = "delete from where id='" & DataGridView1.CurrentRow.Index & "'" Dim c
Dim reader As MySqlDataReader
Try
SqlConn.Open()
Dim query As String
query = "delete from where id='" & DataGridView1.CurrentRow.Index & "'"
Dim command As New MySqlCommand
command = New MySqlCommand(query, SqlConn)
reader = command.ExecuteReader
MessageBox.Show("Data deleted")
ucitaj()
SqlConn.Close()
Catch ex As MySqlException
MessageBox.Show(ex.Message)
Finally
SqlConn.Dispose()
End Try
但是如何直接从数据网格视图添加。我在空字段中输入值,当我单击“添加”时,我想添加它。我知道要添加mysql数据库,我需要使用这个查询
query = "insert into base (id, Username, password, Link) values(Which ones ?)"
这只是又快又脏。事实上,您应该将其参数化 您只需选择它,使currentrow不为空
If Not DataGridView1.CurrentRow Is Nothing Then
Dim id As Integer = DataGridView1.CurrentRow.Cells("ID").Value
Dim username As String = DataGridView1.CurrentRow.Cells("username").Value
Dim pw As String = DataGridView1.CurrentRow.Cells("password").Value
Dim link As String = DataGridView1.CurrentRow.Cells("Link").Value
Dim sqlstr As String = "insert into base (id, Username, password, Link) values(" & id & "," & username & "," & pw & "," & link & ")"
'your code
End If
由于DGV是数据绑定的,因此无法直接添加记录。。您可以随查询添加并刷新DGV..@matzone我想随查询添加,但我在DGV中输入的值无法在DGV中添加新行。。
