5.6 查询界面及代码设计
5.6.1查询界面
系统的查询界面包括：成绩信息查询、课程信息查询、培训计划查询、员工信息查询等。 
 
图6-6 查询界面
5.6.2查询界面代码设计
系统查询界面的代码设计如下（这里以成绩信息查询为例）：
Dim ResultQuery As OpenRs     ’ 定义函数和sql查询语句
Dim sql As String
Dim sql1 As String
Dim sql2 As String
Dim sql3 As String
Dim sql4 As String
Dim sql5 As String

Private Sub cboClassno_KeyPress(KeyAscii As Integer)    ’课程编号的输入范围
KeyAscii = Asc(UCase(Chr(KeyAscii)))
If Not ((Chr(KeyAscii) <= "Z" And Chr(KeyAscii) >= "A") Or (Chr(KeyAscii) <= "9" And Chr(KeyAscii) >= "0") Or KeyAscii = 8) Then
    KeyAscii = 0
End If
End Sub

Private Sub cmdExit_Click()                         ’退出按钮设置
Unload Me
End Sub

Private Sub CmdQuery_Click()                       ’查询按钮设置
sql = "select student_info.student_id,student_info.student_name,result_info.course_no,result_info.course_name,result_info.exam_no,result_info.result from  result_info inner join  student_info on result_info.student_id=result_info.student_id inner join  course_info on result_info.course_no=course_info.course_no where 1=1"   ’用sql语句连接几个相关表
If txtStudentId.Text <> "" Then                         ’以下设置各分支语句
    sql1 = "and student_info.student_id='" & txtStudentId.Text & "'"
Else
    sql1 = " "
End If

If txtStudentName.Text <> "" Then
    sql2 = "and student_info.student_name='" & txtStudentName.Text & "'"
Else
    sql2 = " "
End If

If cboResult.Text <> "" Then
    sql3 = "and result_info.result" & cboResult.Text & ""
Else
    sql3 = " "
