Specifications

Using the Preview view of a report
202 InfoMaker
Supplying argument values or criteria
If the report has retrieval arguments or is set up to prompt for criteria, you
are prompted to supply values for the arguments or to specify criteria.
InfoMaker retrieves the rows. As InfoMaker retrieves, the Retrieve button
changes to a Cancel button. You can click the Cancel button to stop the
retrieval at any time.
Sharing data with the
Data view
The Data view displays data that can be used to populate a report. When the
ShareData pop-up menu item in the Data view is checked, changes you make
in the Data view are reflected in the Preview view and vice versa.
Other options that
affect retrieval
These other options can affect retrieval:
• Query Governor Lets you (or a database administrator) set certain
restrictions on data retrieval. For example, the Query Governor can limit
the number of rows that are retrieved.
For information, see “Using the Query Governor” on page 50.
• Retrieve Rows As Needed Lets you specify that only the rows needed
to display the current portion of the report should be retrieved. When you
scroll downward, additional rows are retrieved. This can speed up
reporting in certain situations.
See “Retrieving rows as needed” on page 233.
• Retrieve Rows to Disk Lets you specify that InfoMaker should save
retrieved data on your hard disk in a temporary file rather than keep the
data in memory. When you preview the report, InfoMaker swaps rows of
data from the temporary file into memory as needed.
For information, see “Saving retrieved rows to disk” on page 234.
Modifying data
You can add, modify, or delete rows in the Preview view. When you have
finished manipulating the data, you can apply the changes to the database.
If looking at data from a view or from more than one table
By default, you cannot update data in a report that contains a view or more than
one table. For more about updating forms, see Chapter 19, “Controlling
Updates in Forms.”
