Projection properties

Double-click a Projection operator to display the Projection Properties dialog. You

can edit the name and description as described in “Properties dialogs” on page 58.

Defining projection columns

You can do the following to edit the column definitions of your projection.

• Click the Project All button to add column definitions for all of the columns in the

input result set. This makes it easy to create your new set of columns if you only

want to tweak the existing schema. If you want to project all columns, do so before

defining any other columns, since doing so will replace all of your existing defini-

tions.

• Click the Add button to add a column definition to your projection.

• To delete one or more columns, select them and click Delete.

• To reorder the columns, select one or more of them and click the Move Up or

Move Down buttons. (If you want to move multiple columns, the selection must be

contiguous.)

• You can edit the properties of each column (see “Working with schemas” on

page 60 for information about setting the name, type, precision, and scale of col-

umns):

 Name: Click in a column’s Name field to rename it.
