SQL查询选择放入变量

Question

Dim dt As New DataTable
dt = runsql("select Question_Topic, Question_Difficuilty from QuestionMutli) where Question_Topic = '" & quiztopic & "' and Question_Difficuilty = " & DifficultyLevel & "")

我写了这段代码，如果它们与测验主题变量和难度级别变量匹配，则将记录放在dt变量中，但是当程序运行dt = ...行时，它会出现：

 System.Data.OleDb.OleDbException: 'Syntax error (missing operator)
 in query expression 'Question_Difficuilty QuestionMutli Topic where 
Question_Topic = 'Algebra And Functions' and Question_Difficuilty = 1'.'

测验主题变量是字符串，难度级别是整数。这是MS Access。

有谁知道导致语法错误的原因是什么？

Answer 1

你的表格名称为QuestionMutli后，你还有一个额外的关闭。
