Declares an INTERVAL DAY TO MINUTE value in an expression.

Syntax element …

sign

an optional minus sign to indicate a negative interval. The default is a positive interval.

The sign must be outside the apostrophes that enclose string.

string

one to four digits representing the number of days followed by a pad character and two digits representing the number of hours, followed by a colon and two digits representing the number of minutes. Besides the pad character, no other spaces or new line characters are allowed between the apostrophes.

Note: For the digits representing the number of days, only digits are parsed and converted to numeric. For example, '1.05' is treated as '105'.

INTERVAL DAY TO MINUTE literals are partly ANSI SQL:2011 compliant.

The ANSI definition places the optional sign within the apostrophes; the Teradata implementation places the optional sign outside the apostrophes.

INTERVAL DAY TO MINUTE

For details on the INTERVAL DAY TO MINUTE type, see “INTERVAL DAY TO MINUTE Data Type” on page 161.

This example adds a 30 day, 12 hour, and 30 minute interval to the current system timestamp.

   SELECT INTERVAL '30 12:30' DAY TO MINUTE + CURRENT_TIMESTAMP;
 
      ( 30 12:30+Current TimeStamp)
   --------------------------------
   1999-12-04 03:14:26.330000+00:00

In the following query, the decimal point is ignored and the result is an interval of 10 days, 10 hours, and 30 minutes.

   SELECT INTERVAL '1.0 10:30' DAY TO MINUTE;
