CHAPTER 4 Defining DataWindow Objects
DataWindow Designer User’s Guide 115
As you select columns, they display in the grid at the bottom of the dialog box
in the order in which you select them. If you want the columns to display in a
different order in the DataWindow object, select a column name you want to
move in the grid and drag it to the new location.
Specifying sorting criteria
In the grid at the bottom of the Quick Select dialog box, you can specify if you
want the retrieved rows to be sorted. As you specify sorting criteria,
DataWindow Designer builds an
ORDER BY clause for the SELECT statement.
❖ To sort retrieved rows on a column:
1 Click in the Sort row for the column you want to sort on.
DataWindow Designer displays a drop-down list:
2 Select the sorting order for the rows: Ascending or Descending.
Multilevel sorts
You can specify as many columns for sorting as you want. DataWindow
Designer processes the sorting criteria left to right in the grid: the first column
with Ascending or Descending specified becomes the highest level sorting
column, the next column with Ascending or Descending specified becomes the
next level sorting column, and so on.
If you want to do a multilevel sort that does not match the column order in the
grid, drag the columns to the correct order and then specify the columns for
sorting.
Specifying selection criteria
You can enter selection criteria in the grid to specify which rows to retrieve.
For example, instead of retrieving data about all employees, you might want to
limit the data to employees in Sales and Marketing, or to employees in Sales
who make more than $80,000.
