More than a year ago bought @mrexcel's "Let Excel Fly" this book. The overall idea is to use Access combined with Excel to significantly improve data analysis efficiency.
Recently I took it out and looked at it. The 15th chapter, more "Advanced" than the advanced screening, P241. Mainly about multi-table association query, can be applied to one-to-many scenarios.
P248: Three types of join properties.
Union union queries can be used to implement multi-table data merging with the same table header.

The error message is as follows: The data source does not contain a visible table.
Later found the reasons and solutions are as follows:
With the visual Query Designer in Access, you can largely avoid Excel in Excel not directly importing "crosstab queries" and "union union queries" in Access.
The detour is to make a " select query " based on "crosstab query" and "Federated query", then import this "select query" in Excel to
More Impressions:
One, 15.4 data summary query, similar to the SUBTOTAL function.
Second, the reason to use Access, because of high efficiency, suitable for large data volume. See P241 for more reasons.
