Formatting Columns
COLUMN command formats the display of column headings and column data.
The simplified syntax for the COLUMN command is as follows:
COL[UMN] {column | alias} [options]
where
- column specifies the column name.
- alias specifies the column alias to be formatted. You can then reference your alias in the COLUMN command.
- options specifies one or more options to be used to format the column or alias.
- There are a number of options you can use with the COLUMN command.
The following table shows some of these options.
Option Description FOR[MAT] format Sets the format for the display of the column or alias to that specified in the format string. HEA[DING] heading Sets the text for the heading of the column or alias to that specified in the heading string. JUS[TIFY] [{ left | center | right }] Aligns the column output to the left, center, or right. WRA[PPED] Wraps the end of a string onto the next line of output. This option may cause individual words to be split across multiple lines. WOR[D_WRAPPED] Similar to the WRAPPED option except that individual words aren"t split across two lines. CLE[AR] Clears any formatting of columns (sets the formatting back to the default).
The format string in the previous table may take a number of formatting parameters.
The parameters you specify depend on the data stored in your column:
- If your column contains characters, you can use Ax to format the characters, where x specifies the width for the characters. For example, A12 sets the width to 12 characters.
- If your column contains numbers, you can use any of the number formats. For example, $99.99 sets the format to a dollar sign, followed by two digits, the decimal point, and another two digits.
- If your column contains a date, you can use any of the date formats. For example, MM-DD-YYYY sets the format to a two-digit month (MM), a two-digit day (DD), and a four-digit year (YYYY).

Reporting Tools in Oracle"s SQL*Plus: COLUMN
Change the way a column displays by using the COLUMN command
The COLUMN command has the following syntax:
COLUMN column-name FORMAT format-specification
where
column-name is the column heading you wish to format.
The format-specification uses a"s for text and 9"s for numbers, like this:
an - text format for a field width of n
9n - numeric format with no decimals for a field width of numbers of size n
