Declares an INTERVAL MINUTE TO SECOND value in an expression.
Result type: INTERVAL MINUTE TO SECOND Data Type
INTERVAL MINUTE TO SECOND 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 [ sign ] 'string' MINUTE TO SECOND
- 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.
- One to four digits representing the number of minutes followed by a colon and two digits representing the number of seconds, optionally followed by a decimal point and 1 to 6 digits representing fractional seconds. The decimal point is required if the fractional seconds are included. Spaces and new line characters are not allowed between the apostrophes.For the digits representing the number of minutes, only digits are parsed and converted to numeric. For example, '1.05' is treated as '105'.
Example: INTERVAL MINUTE TO SECOND Literal
The following example subtracts 9 minutes and 30 seconds from the current system timestamp.
SELECT CURRENT_TIMESTAMP - INTERVAL '9:30' MINUTE TO SECOND; (Current Timestamp(6)- 9:30) -------------------------------- 2004-04-01 17:40:19.610000+00:00
In the following query, the decimal point is ignored and the result is an interval of 10 minutes and 30 seconds.
SELECT INTERVAL '1.0:30' MINUTE TO SECOND;
