6.1.2 打印统计
运行打印统计后可以按条件把符合条件的各种信息以报表形式罗列出来，各种信息还可以以打印出来或以报表形式保存。打印统计包括班级统计分析、档案统计分析、课程统计分析、成绩统计分析和交费统计分析五类。
班级统计分析（如：界面如图四）
（图四）
代码如下：
Private Sub Command1_Click() Dim SQLoriginal As String Dim SQLadd As String Dim SQLorder As String Dim strSql As String
SQLoriginal = \年级,专业,人数,辅导员,备注 FROM 班级表 \SQLadd = \年级=年级 AND 专业=专业 \SQLorder = \
If Check1.Value = 1 And IsNumeric(Text1) Then SQLadd = SQLadd + \年级='\End If
If Check2.Value = 1 And Not IsNull(Text2) Then SQLadd = SQLadd + \专业='\End If
If Check3.Value = 1 And IsNumeric(Text3) Then SQLadd = SQLadd + \人数='\End If
If Check4.Value = 1 And Not IsNull(Text4) Then
SQLadd = SQLadd + \辅导员='\

strSql = SQLoriginal + SQLadd + SQLorde If Dat_Main.rsDat_Class.State = 1 Then Dat_Main.rsDat_Class.Close End If
Dat_Main.rsDat_Class.Open strSql Dat_Class.Show vbModal Text1.Text = \Text2.Text = \Text3.Text = \Text4.Text = \
End Sub
Private Sub Command2_Click() Unload Me End Sub
Private Sub Form_Load() Text1.Text = \Text2.Text = \Text3.Text = \Text4.Text = \End Sub
Private Sub Text1_Change() End Sub
Private Sub Text3_Change()
End Sub
档案分析统计（如：界面如图五）
（图五）
代码如下：
Private Sub Command1_Click() Dim SQLoriginal As String Dim SQLadd As String Dim SQLorder As String Dim strSql As String
On Error Resume Next
SQLoriginal = \学生档案 \SQLadd = \学号=学号 AND 姓名=姓名 \SQLorder = \
If Check1.Value = 1 And IsNumeric(Text1) Then SQLadd = SQLadd + \学号='\End If
If Check2.Value = 1 And Not IsNull(Text2) Then SQLadd = SQLadd + \姓名='\End If
If Check3.Value = 1 And Not IsNull(Text3) Then SQLadd = SQLadd + \专业='\End If
If Check4.Value = 1 And IsDate(DTPicker1) Then
SQLadd = SQLadd + \出生年月= # \End If
strSql = SQLoriginal + SQLadd + SQLorde If Dat_Main.rsDat_Strudent.State = 1 Then Dat_Main.rsDat_Strudent.Close End If
Dat_Main.rsDat_Strudent.Open strSql Dat_Strudent.Show vbModal Text1.Text = \Text2.Text = \Text3.Text = \ End Sub
Private Sub Command2_Click() Unload Me End Sub

Private Sub Text1_Change()
End Sub
课程统计分析（如：界面如图六）
（图六）
代码如下：
Private Sub Command1_Click() Dim SQLoriginal As String Dim SQLadd As String Dim SQLorder As String Dim strSql As String
SQLoriginal = \课程表 \
SQLadd = \专业=专业 AND 课程名称=课程名称 \SQLorder = \
If Check1.Value = 1 And Not IsNull(Text1) Then SQLadd = SQLadd + \专业='\End If
If Check2.Value = 1 And Not IsNull(Combo1) Then SQLadd = SQLadd + \课程性质='\End If
'If Check3.Value = 1 And Not IsNumeric(Text2) Then 'SQLadd = SQLadd + \课时='\'End If
If Check4.Value = 1 And Not IsNull(Text3) Then SQLadd = SQLadd + \课程名称='\End If
strSql = SQLoriginal + SQLadd + SQLorde If Dat_Main.rsDat_Grean.State = 1 Then Dat_Main.rsDat_Grean.Close End If
Dat_Main.rsDat_Grean.Open strSql Dat_Grean.Show vbModal Text1.Text = \Combo1.Text = \'Text2.Text = \Text3.Text = \End Sub
Private Sub Command2_Click() Unload Me
End Sub
