mysql - vb.net MySQLDataAdapter 中的双重 SQL 查询

Question

我不明白为什么这一行在 DataGrid 中不返回任何内容，而当我使用一个 SQL 查询(不是双 SELECT)时它工作正常:

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

Answer 1

请检查更新的答案。

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