Column Headings

Specify column headings using the HEADING clause of the COLUMN command:

COLUMN employee_name HEADING "Employee Name"

Either single or double quotes may be used to enclose the heading text.

To specify a multiline heading, use the vertical bar, or pipe, character (|) to specify the location of the line break. For example:

COLUMN employee_name HEADING "Employee|Name"

Headings of text columns are aligned to the left. Headings of numeric columns are aligned to the right. Use the JUSTIFY clause to alter that behavior:

COLUMN employee_name HEADING "Employee|Name" -
   JUSTIFY RIGHT
COLUMN employee_name HEADING "Employee|Name" -
   JUSTIFY CENTER

Use SET HEADSEP to change the line-break character to something other than a vertical bar. Use SET UNDERLINE to change the underline character to something other than a hyphen.
