我寫的,在MS SQL Server Express的2014年創建表的功能在這裏:我可以使用ADO.NET和C#在MS SQL Express 2014 LocalDB中創建表嗎?
private static void createAndAlterTables()
{
try
{
// Создать соединение с БД.
using (SqlConnection sqlCon = new SqlConnection(ConfigurationManager.ConnectionStrings["sqlConnection"].ConnectionString))
{
try
{
SqlCommand sqlCom = new SqlCommand();
sqlCom.Connection = sqlCon;
sqlCon.Open();
MessageBox.Show("Выполняется создание таблиц", "Сообщение", MessageBoxButton.OK, MessageBoxImage.Information);
sqlCom.CommandText = @"CREATE TABLE [dbo].[AddedDevices](

sqlCom.ExecuteNonQuery();
MessageBox.Show("Таблица 'AddedDevices' успешно создана", "Сообщение", MessageBoxButton.OK, MessageBoxImage.Information);

當我連接到MS SQL Server Express的2014年和嘗試創建表,那麼結果是成功的。但是,當我連接到從InstallShield 2016 Premier(21天試用版)的先決條件安裝的MS SQL Server Express LocalDB時,則不會創建表。 SQL Server類型(Express和Express LocalDB)有沒有原因?或者我在我的代碼中做了任何錯誤。您的幫助將受到高度讚賞。
答案顯然是肯定的。你問來幹什麼?你有錯誤嗎?例外?什麼東西?發佈* full *異常消息,包括調用堆棧。你可以使用'Exception.ToString'獲得那個 –
如果沒有錯誤,那麼你如何檢查丟失的表?你在連接字符串中使用DataDirectory嗎? – Steve
我不在連接字符串中使用DataDirectory。 – Prohor
