Excluding Fields from the Output
At times, you need to include a column in your query that you don't want displayed in the query output; this is often the case with columns used solely for criteria. Figure 4.30 shows an example. If you run this query, you get the total, average, count, and maximum sales grouped by both country and order date. However, you want to group only by country and use the order date only as criteria. Therefore, you need to set the Total row of the query to Where, as shown in Figure 4.31. The column used in Where has been excluded from the query result. You can easily determine this by noting that the check box in the Show row of the Order Date column is unchecked.Understanding Nulls and Query Results
Null values in your table's fields can noticeably affect query results. A Null value is different from a zero or a zero-length string, which indicates that the data doesn't exist for a particular field; a field contains a Null value when no value has yet been stored in the field. (As discussed in Chapter 2, you enter a zero-length string in a field by typing two quotation marks.) Null values can affect the results of multitable queries, queries including aggregate functions (Totals queries), and queries with calculations. Null values can also affect the result of aggregate queries. For example, if you perform a count on a field containing Null values, the Access Database Engine includes in the count only records having non-Null values in that field. If you want to get an accurate count, it's best to perform the count on a primary key field or some other field that can't have Null values.This material orginally appeared in Alison Balter's book Mastering Microsoft Office Access 2007 Development.
