进行 2 次查询；一

Question

您好，我对服务器命令有点陌生，所以我希望有人能帮助我进行此查询。

我正在尝试将来自 2 个查询的数据插入组合框，但缺乏构建查询的知识。

cmbGroups.RowSource = "Select GroupName, GroupNum from tblGroupHeader Where GroupName like '" & txtgroupSearch.Value & "*' or GroupNum like '" & txtgroupSearch.Value & "*';"
cmbGroups.Requery
cmbGroups.SetFocus
cmbGroups.Dropdown

cmbGroups.RowSource = "Select Alsoknown, GroupNum from tblAlsoKnown"

我还希望 AlsoKnown 中的 groupNum 与 GroupHeader 中的 GroupNum 位于同一列下。这可能吗？

我正在测试一些东西，我想我已经接近答案了新查询：

Select tblGroupHeader.GroupName, tblGroupHeader.GroupNum, tblAlsoKnown.AlsoKnown from tblGroupHeader INNER JOIN tblAlsoKnown ON tblGroupHeader.GroupNum = tblAlsoKnown.GroupNum Where GroupName like '" & txtgroupSearch.Value & "*' or GroupNum like '" & txtgroupSearch.Value & "*';"

按照 Marc B 的暗示进行连接查询：

cmbGroups.RowSource = "SELECT tblGroupHeader.GroupName" _
                           & ", tblGroupHeader.GroupNum" _
                           & ", tblAlsoKnown.AlsoKnown" _
                    & " FROM tblGroupHeader" _
                       & " LEFT JOIN tblAlsoKnown ON tblGroupHeader.GroupNum = tblAlsoKnown.GroupNum" _
                    & " WHERE tblGroupHeader.GroupName like '" & txtgroupSearch.Value & "*'" _
                          & " OR tblGroupHeader.GroupNum like '" & txtgroupSearch.Value & "*';"

cmbGroups.Requery
cmbGroups.SetFocus
cmbGroups.Dropdown
