Question

protected void Button2_Click(object sender, EventArgs e)
{
    Response.Write(Execute("SELECT NOW()"));
}

public string Execute(string storedProcedureName)
{
    using (EntityConnection connection = (EntityConnection)new EGModel.EGEntity().Connection)
    {
        using (EntityCommand command = connection.CreateCommand())
        {
            command.CommandType = CommandType.Text;
            command.CommandText = storedProcedureName;
            connection.Open();
            return command.ExecuteScalar().ToString();
        }
    }
}

我收到错误“查询语法无效。靠近第1行，第13列。”;我很好奇，为什么这个错误？（Mysql实体连接）

Answer 1

    var A = new EGModel.EGEntity().Connection;

    var command = ((EntityConnection)(A)).StoreConnection.CreateCommand();
    command.CommandType = System.Data.CommandType.Text;
    command.CommandText = "SELECT NOW()";
    ((EntityConnection)(A)).StoreConnection.Open();
    string id = (string)command.ExecuteScalar();
