Invoked via reflection. @see SqlOperators
ts
- Timestamp to validate.public static @Nullable java.lang.Long validateTimeInterval(@Nullable java.lang.Long arg, org.apache.beam.vendor.calcite.v1_26_0.org.apache.calcite.avatica.util.TimeUnit unit)
ZetaSQL validates that if we represent interval in milliseconds, it will fit into Long.
In case of SECOND or smaller time unit, it converts timestamp to microseconds, so we need to convert those to microsecond and verify that we do not cause overflow.
Invoked via reflection. @see SqlOperators
arg
- Argument for the interval.unit
- Time unit used in this interval.
