SECOND

>>-SECOND--(--expression--)------------------------------------><
 

The schema is SYSIBM.

The SECOND function returns the seconds part of a value.

The argument must be a time, timestamp, time duration, timestamp duration or a valid character string representation of a time or timestamp that is neither a CLOB nor a LONG VARCHAR.

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 time, timestamp or valid string representation of a time or timestamp:
  • The result is the seconds 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 seconds part of the value, which is an integer between -99 and 99. A nonzero result has the same sign as the argument.

Examples:

• Assume that the host variable TIME_DUR (decimal(6,0)) has the value 153045.

    SECOND(:TIME_DUR)
  

  Returns the value 45.

• Assume that the column RECEIVED (timestamp) has an internal value equivalent to 1988-12-25-17.12.30.000000.

    SECOND(RECEIVED)
  

  Returns the value 30.
