Double SQL Query in vb.net MySQLDataAdapter

Question

我无法弄清楚为什么这一行在DataGrid中不返回任何内容，而当我使用一个SQL查询（不是double SELECT）时，它运行良好：

Dim DataAdapterInb As New MySqlDataAdapter("SELECT * FROM (SELECT * From inbox WHERE receiverid='" & ID & "') LIMIT 0,5;", MySqlConnection)

Answer 1

Dim DataAdapterInb As New MySqlDataAdapter
("SELECT t.* FROM 
       //^Changed
(SELECT * From inbox WHERE receiverid='" & ID & "')t
LIMIT 0,5;", MySqlConnection)                    //^Changed
