ADD_MINUTES scalar function
The ADD_MINUTES function returns a timestamp value that represents the first argument plus a specified number of minutes.
The schema is SYSIBM.
-
expression
- An expression that specifies the starting timestamp. The expression must return a value that is a TIMESTAMP, CHAR, or VARCHAR data type. In a Unicode database, the expression can also be a GRAPHIC or VARGRAPHIC data type. CHAR, VARCHAR, GRAPHIC, and VARGRAPHIC are supported by using implicit casting. The expression must not return a value that is a DATE (SQLSTATE 42815). If expression is a CHAR, VARCHAR, GRAPHIC, or VARGRAPHIC data type, it must be a valid string that is accepted by the TIMESTAMP scalar function. numeric-expression
- An expression that specifies the number of minutes to add to the starting timestamp specified by expression. The expression must return a value that is a built-in numeric, CHAR, or a VARCHAR data type. In a Unicode database, the expression can also be a GRAPHIC or VARGRAPHIC data type. CHAR, VARCHAR, GRAPHIC, and VARGRAPHIC are supported by using implicit casting. If the expression is not a BIGINT, it is cast to BIGINT before the function is evaluated. A negative numeric value can be used to subtract minutes.
The result of the function is a timestamp with the same precision as expression, if expression is a timestamp. Otherwise, the result is a TIMESTAMP(12). If any argument can be null, the result can be null; if any argument is null, the result is the null value.
Examples
- Assume that the current timestamp is January 31, 2007, 01:02:03.123456.
Set the host variable ADD_MINUTE with the current timestamp plus 1
minute.
The host variable ADD_MINUTE is set with the value representing 2007-01-31-01.03.03.123456.SET :ADD_MINUTE = ADD_MINUTES(CURRENT TIMESTAMP, 1)
- Assume that TIMESTAMP is a host variable with the value July 27,
1965 23:58:59. Set the host variable ADD_MINUTE with the value of
that timestamp plus 3 minutes.
The host variable ADD_MINUTE is set with the value representing the timestamp plus 3 minutes, 1965-07-28-00.01.59.SET :ADD_MINUTE = ADD_MINUTES(:TIMESTAMP,3)
- The ADD_MINUTES function and datetime arithmetic can be used to
achieve the same results. The following examples demonstrate this.
In both cases, the host variable TIMESTAMPHV is set with the value '2008-02-29-00.02.59'.SET :TIMESTAMPHV = TIMESTAMP '2008-2-28-23.58.59' + 4 MINUTES SET :TIMESTAMPHV = ADD_MINUTES( TIMESTAMP '2008-2-28-23.58.59', 4)
Now consider the same examples but with 1442 minutes added.
In both cases, the host variable TIMESTAMPHV is set with the value '2008-03-01-00.00.59'.SET :TIMESTAMPHV = TIMESTAMP '2008-2-28-23.58.59' + 1442 MINUTES SET :TIMESTAMPHV = ADD_MINUTES(TIMESTAMP '2008-2-28-23.58.59', 1442)
- Assume that
TIMESTAMP is a host variable with the value July 27, 1965 23:58:59.
Set the host variable ADD_MINUTE with the value of that timestamp
minus 3 minutes.
The host variable ADD_MINUTE is set to 1965-07-27-23.55.59; the value representing July 27, 1965 23:58:59 minus 3 minutes.SET :ADD_MINUTE = ADD_MINUTES(:TIMESTAMP,-3)
