sunjincheng updated FLINK-6811:
-------------------------------
Description:
TIMESTAMPADD(unit,interval,datetime_expr) Adds the integer expression interval
to the date or datetime expression datetime_expr. The unit for interval is
given by the unit argument, which should be one of the following values:
MICROSECOND (microseconds), SECOND, MINUTE, HOUR, DAY, WEEK, MONTH, QUARTER, or
YEAR.
* Syntax:
TIMESTAMPADD(unit,interval,datetime_expr)
* Arguments
**unit: -
**interval: -
**datetime_expr: -
* Return Types
DATAETIME/DATE/TIME
* Example:
SELECT TIMESTAMPADD(month, 1, '2017-05-31') --> '2017-06-30 00:00:00.000'
SELECT TIMESTAMPADD(WEEK,1,'2003-01-02') -> '2003-01-09'
* See more:

Note: Due to the difference of [[org.apache.calcite.rex.Rex Literal]] between
calcite 1.12 and calcite master we should temp close support the construce of
{{TIMESTAMPADD(SqlTypeFamily.ANY, SqlTypeFamily.INTEGER, SqlTypeFamily.DATE)}},
until upgrade to calcite 1.13.

* Syntax
timestampAdd (datepart SqlTypeFamily.ANY, number:SqlTypeFamily.INTEGER,
date:SqlTypeFamily.TIMESTAMP )
-datepart
Is the part of date to which an integer number is added.
-number
Is an expression that can be resolved to an int that is added to a datepart of
date
-date
Is an expression that can be resolved to a time.
* Example
SELECT timestampAdd(month, 1, '2017-05-31') from tab; --> 2017-06-30
00:00:00.000
Note: Due to the difference of [[org.apache.calcite.rex.Rex Literal]] between
calcite 1.12 and calcite master we should temp close support the construce of
{{TIMESTAMPADD(SqlTypeFamily.ANY, SqlTypeFamily.INTEGER, SqlTypeFamily.DATE)}},
