Breaks the body of column-oriented reports into summary groups.
COLUMN BREAK level [HEADING reportitem [:format:]]
[FOOTING reportitem [:format:]]
|level||The break level number (an integer greater than or equal to zero).
In the hierarchy of breaks, the higher the level number, the more minor the break. (For example, a level 1 break also triggers breaks at level 2, level 3, and so on.)
|HEADING||Introduces the “heading clause” for the break level, which can consist of a break orientation statement, a number of report items and their format instructions, or both. The footing displays each time the break level is triggered.|
|FOOTING||Introduces the “footing clause” for the break level, which can consist of a break orientation statement, a number of report items and their format instructions, or both. The heading displays each time the break level is triggered.|
|reportitem||Any valid expression that yields a value for display in the break heading or break footing. The heading and footing can each display a series of reportitems. Each item has its own associated format.|
|format||A set of instructions defining the format for the associated reportitem. Format is enclosed in : (colons) and can consist of any valid combination of format options.|
The COLUMN BREAK command breaks the body of a column-oriented report into summary groupings.
Each time a BREAK command triggers a break at a specified level, the COLUMN BREAK for that level and all levels lower in the hierarchy are triggered.
Report items in the COLUMN BREAK heading can include individual values from the first member of the current group. Report items in the COLUMN BREAK footing can include individual values only from the last member of the current group. However, summary data computed over all members of the group can be displayed in the footing. Use aggregate functions.
If both the heading and footing clauses are omitted, a column break at the indicated level causes report formatting to recommence at the left-hand side of the page, beneath any previously formatted columns.
