"select * form 样本数据 where 车号=' " &text1.text &"' and 日期='" &combo1.text &"'"
举例说明,实现如下多条件查询:
Private Sub Command1_Click() Dim jsql jsql = ""
Dim smyregion As String If Check1.Value = 1 Then
jsql = "图书名称 like '%" + Text1.Text + "%'" End If
If Check2.Value = 1 Then If jsql = "" Then
jsql = "作者姓名 like'%" + Text2.Text + "%'" Else
jsql = jsql &"and 作者姓名 like'%" + Text2.Text + "%'" End If End If
If Check3.Value = 1 Then If jsql = "" Then
jsql = "出版社名称 like'%" + Text3.Text + "%'" Else
jsql = jsql &"and 出版社名称 like '%" + Text3.Text + "%'" End If End If
If Check4.Value = 1 Then If jsql = "" Then
jsql = "出版时间 like '%" + Text4.Text + "%'" Else
jsql = jsql &"and 出版时间 like '%" + Text3.Text + "%'" End If End If
If Check5.Value = 1 Then If jsql = "" Then
jsql = "图书类别 like '%" + Text5.Text + "%'"
Else
jsql = jsql &"and 图书类别 like '%" + Text5.Text + "%'" End If End If
If jsql = "" Then
MsgBox "请选择查询条件!", vbInformation, "图书音像管理系统" Exit Sub Else
Adodc1.RecordSource = "select * from book where " &jsql Adodc1.Refresh End If
If Adodc1.Recordset.RecordCount >0 Then Set DataGrid1.DataSource = Adodc1 End If End Sub
Private Sub Command2_Click() Unload Me End Sub
sql = "select * from 基本信息 where 供货公司 like '%" &Trim(Text1.Text) &"%'and 车牌号 like '%" &Trim(Text2.Text) &"%' and 日期>= #" &DTPicker1.Value &"# And 日期<= #" &DTPicker2.Value &"# "用模糊查询,如果文本框内容为空,则显示全部。
