. Additionally, you can limit the result set by
applying a filter condition to the result of the join. You are limiting the result to a
particular ticket number.

SELECT * FROM
NESTED TABLES (ticket a descendants(ticket.bagInfo.flightLegs b))
Explanation: This is an example of a join where the target table
ticket
is joined with its descendant bagInfo
. A
descendant table can be any level hierarchically below a table ( For example
fightLegs
is the child of bagInfo
which is the
child of ticket
, so flightLegs
is a descendant of
ticket
). All the rows from the ticket
table will
be fetched. If any row from the ticket
table does not have a matching
row in the flightLegs
table, then NULL values will be displayed for
those rows of the flightLegs
table.

Explanation: This is an example of a join where the target
tableticket
is joined with its descendant bagInfo
.
Additionally, you can limit the result set by applying a filter condition to the result
of the join. You are limiting the result to a particular ticket number.
The result has two rows, implying there are two flight legs for this ticket number.

SELECT b.id,count(*) AS NUMBER_HOPS

GROUP BY b.id
Explanation: You group the data based on the bag id (using GROUP BY) and get the count of flight legs ( using count() ) for every bag.

GROUP BY b.id
Explanation: You group the data based on the bag id (using GROUP BY) and get the count of flight legs ( Using count()) for every bag. Additionally, you filter the results for a particular ticket number.

NESTED TABLES(ticket a descendants(ticket.bagInfo b))
WHERE CAST (b.bagArrivalDate AS Timestamp(0))>=

Explanation: This is an example of a join where the target
tableticket
is joined with its child table
bagInfo
. The filter condition is applied on the
bagArrivalDate
. The CAST
function is used to
convert the string into Timestamp and then the values are compared.
