]
sunjincheng updated FLINK-6811:
-------------------------------
Description:
* 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)}},
until upgrade to calcite 1.13.
