Internal Representation of INTERVAL MINUTE

Storage Format Total Length
SMALLINT 2 bytes

External Representation of INTERVAL MINUTE

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

Type Format
CHARACTER(precision + 1) '-m(precision)'

For example, for INTERVAL MINUTE(2), the value might be something like '  49 '.

Range of Values

The range of values for INTERVAL MINUTE is as follows.

Type and Precision Minimum Value Maximum Value
INTERVAL MINUTE(1) -'9' '9'
INTERVAL MINUTE(2) -'99' '99'
INTERVAL MINUTE(3) -'999' '999'
INTERVAL MINUTE(4) -'9999' '9999'
Decimal values are not allowed for Interval data types except for second intervals.

Implicit and Explicit INTERVAL MINUTE Conversion

Vantage 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.
