insert into 语法问题?
str = "insert into selecting(number,question,result1,result2,result3,rusult4,answer)values('" & TextBox6.Text & "','" & TextBox1.Text & "','" & TextBox2.Text & "','" & TextBox3.Text & "','" & TextBox4.Text & "','" & TextBox5.Text & "','" & DropDownList1.SelectedItem.Value & "')"
请问到底有什么语法错误,我实在想不出来
