Queries

You can use queries to compile data from one or more tables. Selection criteria can be used to filter certain data records.

easymap can also set filter on tables (by clicking with the right mouse button in the table) But these filters only change the display of data in the table window. These filters are not taken into account in analyses.

Create new queries

A new query can be created with the command New query in the menu Data or with a click on the button in the toolbar in the control window Data.

After clicking New Query the Query Wizard opens. The query wizard consists of 2 parts:

1. Add table - Select the tables on which to base your query. You can also add more tables in the next step.

2. open the dialog query.

Changing Queries

To change a query, right-click the query in the control window Data under Queries, and then click Properties.

If the query table is already open, click the second button from the left on the table toolbar Edit Query.
