Purpose

Identifies a field as an INTERVAL value defining a period of time in minutes and seconds.

Syntax



precision
The permitted range of digits for MINUTE, ranging from one to four.
The default is two.
fractional_seconds_precision
The fractional precision for the values of SECOND, ranging from zero to six.
The default is six.
attributes
Appropriate data type, column storage, or column constraint attributes.
See Core Data Type Attributes and Storage and Constraint Attributes for specific information.

ANSI Compliance

INTERVAL MINUTE TO SECOND is ANSI SQL:2011 compliant.

Internal Representation of INTERVAL MINUTE TO SECOND

Conceptually, INTERVAL MINUTE TO SECOND is treated as a record composed of the following fields.

Field Name Storage Format Total Length
MINUTE SMALLINT 6 bytes
SECOND INTEGER

External Representation of INTERVAL MINUTE TO SECOND

INTERVAL MINUTE TO SECOND types are imported and exported in record and indicator modes as CHARACTER data using the client character set.

WHEN fractional_seconds_precision is … THEN the type and format are …
0 Type: CHARACTER(precision + 4)
Format: '-m(precision):ss'
n

where n is 1 - 6

Type: CHARACTER(precision + n + 5)
Format: '-m(precision):ss.s(n)'

For example, for INTERVAL MINUTE(2) TO SECOND(0), the value might be something like ‘ 17:39’.

Implicit and Explicit INTERVAL MINUTE TO SECOND Conversion

Teradata Database performs implicit conversion from one Interval data type to another Interval type in some cases. You can also use CAST to explicitly convert one Interval type to another.

Conversions are possible only within the same INTERVAL family. For example, you may convert a YEAR interval to months, but not to days or hours.

For more information, see “Data Type Conversions” in Teradata Vantage™ SQL Functions, Expressions, and Predicates, B035-1145.

Example: INTERVAL MINUTE TO SECOND Data Type

The following statement creates a table with an INTERVAL MINUTE TO SECOND column:

CREATE TABLE TimeInfo
  (Id INTEGER
  ,Offset INTERVAL MINUTE (1) TO SECOND (2));
   
INSERT TimeInfo (1001, INTERVAL '6:15.24' MINUTE TO SECOND);
