Update
Query
button. This refreshes the screen and reduces
the number of columns available in the

selector. We can always change the

Exploring column criteria
Three criteria columns are provided by default. This section discusses the options we
have for editing their criteria. These include options for selecting columns, sorting
individual columns, entering conditions for individual columns, and so on.

The
Column
selector contains all the individual columns for the selected tables, plus
a special choice ending with an asterisk (
*
) for each table, which means that all the
columns are selected.
