使用我的Windows窗体应用程序中的命令对象更新了访问数据库中的行的简单任务。我能够插入记录但不知何故无法更新记录:
private void openDB()
{
DBPath = Application.StartupPath + "\\myDB.mdb";
conn = new OleDbConnection("Provider=Microsoft.Jet.OleDb.4.0;" + "Data Source=" + DBPath);
conn.Open();
}
private void btnUpdate_Click(object sender, EventArgs e)
{
string insertString;
openDB();
string updateString;
updateString = "Update Address SET Name='"+ txtName.Text.Trim() + "', IsActive='" + chkAddressActive.Checked +"' where MemberID="+txtMemberID.Text.Trim();
//MessageBox.Show(updateString);
using (OleDbCommand updateCmd = new OleDbCommand(updateString, conn))
{
updateCmd.ExecuteNonQuery();
MessageBox.Show("Record Updated Successfully", "Transaction", MessageBoxButtons.OK, MessageBoxIcon.Information);
dgView.Enabled = true;
ReloadDataForSelectedMember();
}
}
答案 0 :(得分:0)
您可能需要这样的内容,因为名称是保留字:
updateString = "Update Address SET [Name] = '" + txtName.Text.Trim() + "', IsActive = " + chkAddressActive.Checked.ToString() + " Where MemberID = " + txtMemberID.Text.Trim();
