Create a Totals Query
When a query is created, by default, it is a detail query (each record is displayed in the output). The query may be modified to become a totals query (only summarized records are displayed).
- In the Field List grid, right-click the columns header, and select Toggle Totals. The Total column appears in the Field List grid, displaying the default value
Group By
, for each field, excluding calculated fields. - For each field in the list, click the drop-down list, and select the appropriate Total value, based on the planned output for the query. See the following table for more information:
- For visible fields, use when criteria will be applied to the grouped field. This is expressed in the SQL code as a HAVING statement.
- For fields that are not visible, use when criteria will be applied at a detail record level. This is expressed in the SQL code as a WHERE statement.
