在Visual Basic中,你可以使用ADO.NET库来动态生成SQL查询。以下是使用VB.NET编写包含类似上述SQL语句的一个示例:
```vb.net
Imports System.Data.SqlClient
Dim connectionString As String = "your_connection_string_here"
Dim sql As String = "SELECT * FROM your_table_name WHERE " & _
"(作者 = @author AND Status IN (@statusList)) AND Validity = @validity"
Using connection As New SqlConnection(connectionString)
Dim command As New SqlCommand(sql, connection)
command.Parameters.AddWithValue("@author", "张泽强")
Dim statusList() As String = {"仅提交", "审核中", "被退回"}
Dim statusParam As SqlParameter
For Each s In statusList
statusParam = New SqlParameter("@status" & statusList.Count + 1, SqlDbType.VarChar)
statusParam.Value = s
command.Parameters.Add(statusParam)
Next
statusParam = New SqlParameter("@validity", SqlDbType.VarChar)
statusParam.Value = "YES"
command.Parameters.Add(statusParam)
connection.Open()
' 这里可以执行command的ExecuteReader等方法来获取结果
End Using
```
请注意,你需要替换成实际的数据库连接字符串(`connectionString`)和表名(`your_table_name`)。
