Question

我有一个名为lotto的数据库整数列，并尝试使用3个文本框同时过滤datagrid，但无法使用“ LIKE” SQL查询来过滤整数值。如何替换“ LIKE”以使其正常工作？还是有更快的方法同时使用多个datagrid列？

    If TB_regal_3.Text = String.Empty And TB_lotto_3.Text = String.Empty Then
        Me.Mag_pretyBindingSource.Filter = "kod like '%" & TB_kod_3.Text & "%'"
    ElseIf TB_lotto_3.Text = String.Empty Then
        Me.Mag_pretyBindingSource.Filter = "kod like '%" & TB_kod_3.Text & "%' AND regal like '%" & TB_regal_3.Text & "%'"
    ElseIf TB_regal_3.Text = String.Empty Then
        Me.Mag_pretyBindingSource.Filter = "kod like '%" & TB_kod_3.Text & "%' AND lotto like '%" & TB_lotto_3.Text & "%'"
    Else
        Me.Mag_pretyBindingSource.Filter = "kod like '%" & TB_kod_3.Text & "%' AND regal like '%" & TB_regal_3.Text & "%' AND lotto like " & TB_regal_3.Text
