IBM ISERIES SC41-5210-04 - Manual (Page 153)

v If no break fields are selected, no summary functions are selected and final summaries are suppressed.
Only a count of the records is produced.
In a name and address file, for example, you might specify that two fields named
CITY and STATE be
specified as break fields. If
STATE was defined as the break field for break level 1, CITY was defined as the
break field for break level 2, and both fields were specified as break values in break text for their
respective levels, then the following sample report breaks and break text might appear in a report for the
following records:
Records in file: | Lines in report:
|
LNAME CITY STATE | STATE CITY LNAME
Brown Rochester MN | MN Rochester Brown
Jones Rochester MN | Jones
Smith Rochester MN | Smith
. . . |
. . . | Users in Rochester MN
. . . | Count 3
. . . |
Adams St Paul MN | St Paul Adams
. . . |
. . . | Users in St Paul MN
. . . | Count 1
. . . | All Users in MN
. . . | Count 4
. . . |

Calva Rochester NY | NY Rochester Calva
Doe Rochester NY | Doe
Smith Rochester NY | Smith
. . . |
. . . | Users in Rochester NY
. . . | Count 3
. . . | All Users in NY
. . . | Count 3
If you do not specify report breaks, Query prints or displays all the records in the report, one after the
other without any additional spacing or text.
Break level 0 is another level, provided by Query, that you can use. This break level, which occurs only at
the end of the report, is used to print the final summary values for all the specified summary functions at
the end of the report.
Break level 0 has default break text ( FINAL TOTALS), but it can be changed or filled with blanks if you do
not want any final total description or values.
For printed output only, Query suppresses the printing of identical field information within a field that is
defined as a break field. That is, when the contents of a break field are the same in a group of records,
only the first record in the group has that field printed. All the other records in the group do not print the
duplicate contents of that field.
See the previous name and address file example. Even though each record contains a value for the
STATE
field, the value for STATE only appears in its column when the value changes.
However, for the first record at the top of every page, all the information in all report fields is printed again
for ease of reading.
Query assumes you want a blank line after any summaries, unless you specify a new page. If you display
the information rather than print it, Query ignores new page requests.
