主题：条件加载

以下模糊查询代码是否可以作为条件加载的Select语句

Dim txt As String = e.Form.Controls("TextBox1").Text
Dim tbl As Table = Tables("任务单")
If txt = "" Then
    tbl.Filter = ""
Else
    txt = "'*" & txt & "*'"
    tbl.Filter = "任务单编号 Like " & txt & " Or 工装模具编号 Like " & txt & " Or 产品名称 Like " & txt & " Or 产品图号 Like " & txt

 End If
