>expression

An expression that returns a value of one of the following built-in data types:
DATE, TIME, TIMESTAMP, time duration, timestamp duration, or a valid character string representation of a date, time, or timestamp that is not a CLOB.
If a supplied argument is a DATE, it is first converted to a TIMESTAMP(0) value, assuming a time of exactly midnight (00.00.00).
In a Unicode database, if a supplied argument is a GRAPHIC or VARGRAPHIC data type, it is first converted to a character string before the function is executed.

The result of the function is a large integer.
If the argument can be null, the result can be null; if the argument is null, the result is the null value.

The other rules depend on the data type of the argument:

• If the argument is a DATE, TIME, TIMESTAMP, or valid string representation of a date, time or timestamp:
  • The result is the minute part of the value, which is an integer between 0 and 59.
• If the argument is a time duration or timestamp duration:
  • The result is the minute part of the value, which is an integer between -99 and 99. A nonzero result has the same sign as the argument.

Examples

Using the CL_SCHED sample table, select all classes with a duration less than 50 minutes.

     SELECT * FROM CL_SCHED
     WHERE  HOUR(ENDING - STARTING) = 0
     AND    MINUTE(ENDING - STARTING) < 50
