SQLite的，在我的表中插入变量（C＃控制台应用程序）

Question

string TheName = "David"; 
string UserTable = "INSERT INTO USER (name) values (TheName)"; 
SQLiteCommand command2 = new SQLiteCommand(UserTable, m_dbConnection); 
command2.ExecuteNonQuery(); 

我想知道是否有可能在我的SQLite表中插入变量（如TheName示例代码），如果是你怎么样能够做到吗？

Answer 1

您需要的参数化查询：

command2.CommandText = "INSERT INTO User (name) VALUES(@param1)"; 
command2.CommandType = CommandType.Text; 
command2.Parameters.Add(new SQLiteParameter("@param1", TheName)); 

Answer 2

使用参数化查询：

string UserTable = "INSERT INTO USER (name) values ($TheName)"; 
command2.Parameters.AddWithValue("$TheName", TheName);
