HEADING

The HEADING command produces titles and column headings for a report. The heading output is sent to the current outfile. The form of the HEADING command is the same as that of the ROW command. When you use HEADING, however, Oracle OLAP does not add any numeric values from the heading to column subtotals or grand totals.

Frequently, HEADING statements are used in a PAGEPRG program to produce titles or column headings on each page of a report.

Tip:

When you know ahead of time that you do not need the subtotaling capability of the ROW command, use the HEADING command instead of ROW to produce the lines of your report can provide a time savings, because, in this case, Oracle OLAP does not keep track of subtotals.

Syntax

HEADING [attribs] {expression1|SKIP}, [attribs] {expressionN|SKIP}

Parameters

attribs: The attributes that specify the format for each column. (See the ROW command for a list and detailed explanation of the available attributes.)
expression: The text to be used as a column heading. To use literal text for a column heading, enclose the text in single quotes. (See the ROW command for more information on using expressions, attributes, and ACROSS groups to produce columns.)
SKIP: Used instead of an expression to indicate that the column is to be left blank.

Usage Notes

The notes for the ROW command also apply to the HEADING command (except for the note on row and column arithmetic in ROW).

Creating Titles Using Heading

To create a title or subtitle in a report, use HEADING to produce a single "column" with a width equal to the setting of the LSIZE option. You can then center your text within this "column" to produce a centered title.

Maximum Heading Width

The maximum width of any line in a report, including a heading line, is 4,000 characters.

Examples

Example 10-1 Producing Column Headings

In a report, you want to have headings for your columns. You can use a HEADING statement such as the following in your program.

HEADING UNDER '-' CENTER <WIDTH 15 'Product' -
   ACROSS district FIRST 3: district>

This statement produces the following result.

    Product      Atlanta     Boston    Chicago
--------------- ---------- ---------- ----------
