TRUNC(date [, fmt ])

Parameters:

Name Description date The date to truncate. fmt

(Optional) The unit of measure for truncating. If fmt is not present, then the date is truncated to the nearest day.

Return Value Type:

The value returned is always of datatype DATE

Date format models for the TRUNC function:

Applies to:

Oracle 12c, Oracle 11g, Oracle 10g, Oracle 9i

Pictorial Presentation

Example: Oracle TRUNC (date) function

The following statement truncates a specified date :

SELECT TRUNC(TO_DATE(’02-MAR-15′,’DD-MON-YY’), ‘YEAR’) “New Year” FROM DUAL;

Sample Output:

New Year ——— 01-JAN-15

Previous: TO_YMINTERVAL

Next: TZ_OFFSET

TRUNC Function

If a MONEY data type is the argument in a call to thefunction that specifies a scale of zero, the fractional part becomesin the returned value. For example, the following SELECT statement truncates 125.46 and a MONEY column value. It returns 125 and a truncated price in the formfor each row in thetable.

The following example calls thefunction with a column expression that returns a numeric value in a SELECT statement. This statement displays the order number and truncated total price of items whose total price (truncated to the default scale of zero decimal places) is equal to $124.00.

Positive digit values specify truncation to the right of the decimal point; negative digit values specify truncation to the left, as Figure 1 shows.

Figure 1. Examples of negative, zero, and positive truncation factors

Table 1. Format strings for DATETIME arguments to the TRUNC function Format String Effect on Returned Value ‘ YEAR ‘ Truncated to the beginning of the year. The month, day, hour, and minute values truncate to 01-01 00:00 . ‘ MONTH ‘ Truncated to the beginning of the first day of the month. The hour and minute values round to 00:00 . ‘ DD ‘ Truncated to the beginning ( 00:00 = midnight) of the same day. ‘ DAY ‘ If the first argument is a Sunday, midnight ( 00:00 ) on that date is returned. For any other day of the week, midnight on the previous Sunday is returned. ‘ HH ‘ Truncated to the beginning of the hour. The minute value truncates to zero. ‘ MI ‘ Truncated to the beginning of the nearest minute. As for all of these format strings, time units smaller than minute are discarded.

If you omit the format string specification after an initial DATETIME expression argument, the returned value is the value of the first argument truncated to the day, as if you had specified ‘DD’ as the format string.

Examples that follow invoke the TRUNC function with a column expression that returns a DATETIME YEAR TO FRACTION(5) value in a SELECT statement. In these examples, table mytab has only a single row, and in that row the value of mytab.col_dt is 2006-12-07 14:30:12.12300 .

‘YEAR’ as the DATETIME format string: SELECT TRUNC(col_dt, ‘YEAR’) FROM mytab; The value returned is 2006-01-01 00:00 . This query specifiesas the DATETIME format string:The value returned is

SELECT TRUNC(col_dt, ‘YEAR’)::DATE FROM mytab; The value returned is 01/01/2006 . The next query resembles the previous query, but casts the truncated value to a DATE data type:The value returned is

‘MONTH’ as the DATETIME format string: SELECT TRUNC(col_dt, ‘MONTH’) FROM mytab; The value returned is 2006-12-01 00:00 . This example specifiesas the DATETIME format string:The value returned is

TRUNC (date)

241/479

TRUNC (date)

Syntax

trunc_date::=

Purpose

The TRUNC (date) function returns date with the time portion of the day truncated to the unit specified by the format model fmt . The value returned is always of datatype DATE , even if you specify a different datetime datatype for date . If you omit fmt , then date is truncated to the nearest day. Please refer to “ROUND and TRUNC Date Functions” for the permitted format models to use in fmt .

Examples

The following example truncates a date:

SELECT TRUNC(TO_DATE(’27-OCT-92′,’DD-MON-YY’), ‘YEAR’) “New Year” FROM DUAL; New Year ——— 01-JAN-92
