TTITLE

TTITLE

Syntax

TTI[TLE] [printspec [text|variable] ...] [ON|OFF]

where printspec represents one or more of the following clauses used to place and format the text:

COL n

S[KIP] [n]

TAB n

LE[FT]

CE[NTER]

R[IGHT]

BOLD

FORMAT text

Places and formats a specified title at the top of each report page or lists the current TTITLE definition. The old form of TTITLE is used if only a single word or string in quotes follows the TTITLE command.

Terms

Refer to the following list for a description of each term or clause. These terms and clauses also apply to the BTITLE command.

text

Represents the title text. Enter text in single quotes if you want to place more than one word on a single line.

variable

Represents a user variable or any of the following system-maintained values, SQL.LNO (the current line number), SQL.PNO (the current page number), SQL.RELEASE (the current Oracle release number), SQL.SQLCODE (the current error code), or SQL.USER (the current username).

To print one of these values, reference the appropriate variable in the title. You can format variable with the FORMAT clause.

5-110 iSQL*Plus User’s Guide and Reference

TTITLE

OFF

Turns the title off (suppresses its display) without affecting its definition.

ON

Turns the title on (restores its display). When you define a top title, SQL*Plus automatically sets TTITLE to ON.

COL n

Indents to column n of the current line (backward if column n has been passed). “Column” in this context means print position, not table column.

S[KIP] [n]

Skips to the start of a new line n times; if you omit n, one time; if you enter zero for n, backward to the start of the current line.

TAB n

Skips forward n columns (backward if you enter a negative value for n). “Column” in this context means print position, not table column.

LE[FT]|CE[NTER]|R[IGHT]

Left-align, center, and right-align data on the current line respectively. SQL*Plus aligns following data items as a group, up to the end of the printspec or the next LEFT, CENTER, RIGHT, or COL command. CENTER and RIGHT use the SET LINESIZE value to calculate the position of the data item that follows.

BOLD

Prints data in bold print. SQL*Plus represents bold print on your terminal by repeating the data on three consecutive lines. On some operating systems, SQL*Plus may instruct your printer to print bold text on three consecutive lines, instead of bold.

FORMAT text

Specifies a format model that determines the format of following data items, up to the next FORMAT clause or the end of the command. The format model must be a text constant such as A10 or $999. See the COLUMN FORMAT command for more information on formatting and valid format models.

Command Reference 5-111

TTITLE

If the datatype of the format model does not match the datatype of a given data item, the FORMAT clause has no effect on that item.

If no appropriate FORMAT model precedes a given data item, SQL*Plus prints NUMBER values according to the format specified by SET NUMFORMAT or, if you have not used SET NUMFORMAT, the default format. SQL*Plus prints DATE values according to the default format.

Refer to the FORMAT clause of the COLUMN command in this chapter for more information on default formats.

Enter TTITLE with no clauses to list the current TTITLE definition.

Usage

If you do not enter a printspec clause before the first occurrence of text, TTITLE left justifies the text. SQL*Plus interprets TTITLE in the new form if a valid printspec clause (LEFT, SKIP, COL, and so on) immediately follows the command name.

See COLUMN NEW_VALUE for information on printing column and DATE values in the top title.

You can use any number of constants and variables in a printspec. SQL*Plus displays the constants and variables in the order you specify them, positioning and formatting each constant or variable as specified by the printspec clauses that precede it.

The length of the title you specify with TTITLE cannot exceed 2400 characters.

The continuation character (a hyphen) will not be recognized inside a single-quoted title text string. To be recognized, the continuation character must appear outside the quotes, as follows:

TTITLE CENTER ’Summary Report for’ - > ’the Month of May’

Examples

To define “Monthly Analysis” as the top title and to left-align it, to center the date, to right-align the page number with a three-digit format, and to display “Data in Thousands” in the center of the next line, enter

TTITLE LEFT ’Monthly Analysis’ CENTER ’01 Jan 2001’ -

RIGHT ’Page:’ FORMAT 999 SQL.PNO SKIP CENTER -

’Data in Thousands’
