Given the following Core Data Service View Entity Data Definition:
1 @AccessControl.authorizationCheck: #NOT_REQUIRED
2 DEFINE VIEW ENTITY demo_flight_info_join
3 AS SELECT
4 FROM scarr AS a
5 LEFT OUTER JOIN scounter AS c
6 LEFT OUTER JOIN sairport AS p
7 ON p.id = c.airport
8 ON a.carrid = c.carrid
9 {
10 a.carrid AS carrier_id,
11 p.id AS airport_id,
12 c.countnum AS counter_number
13 }
In what order will the join statements be executed?
The order in which the join statements will be executed is:
scarr will be joined with scounter first and the result will be joined with sairport.
Therefore, the join statements will be executed as follows:
First, scarr AS a will be joined with scounter AS c using the join condition a.carrid = c.carrid. This means that all the rows from scarr will be included in the result, and only the rows from scounter that have the same value for the carrid field will be included. If there is no matching row from scounter, the countnum field will be filled with an initial value.
Second, the result of the first join will be joined with sairport AS p using the join condition p.id = c.airport. This means that all the rows from the first join will be included in the result, and only the rows from sairport that have the same value for the id field as the airport field from the first join will be included. If there is no matching row from sairport, the id field will be filled with an initial value.
For the assignment, gv_target = gv_source.
which of the following data declarations will always work without truncation or rounding? Note: There
are 2 correct answers to this question.
You cannot do any of the following:
In ABAP SQL, which of the following retneves the association field _Airline-Name of a CDS view?
Which of the following ON conditions must you insert in place of "???"?
The correct ON condition that must be inserted in place of ''???'' is:
ON Sprojection.carrier_id=Z_Source2.carrier_id
The other options are not valid ON conditions, because:
A . ON Z_Sourcel.camer_id = 7_Source2 carrier_id is not valid because Z_Sourcel and 7_Source2 are not valid data sources in the given code. There is no CDS view or database table named Z_Sourcel or 7_Source2. The correct names are Z_Source1 and Z_Source2. Moreover, the field camer_id is not a valid field in the given code. There is no field named camer_id in any of the data sources. The correct name is carrier_id.
Which of the following are incomplete ABAP types? Note: There are 2 correct answers to this question.
The following are incomplete ABAP types:
The following are not incomplete ABAP types, because they specify all the attributes of a data type:
B . T is a type for time values in the format HHMMSS. The length of the time value is fixed at 6 characters and does not have to be specified when a data object or a constant is defined with this type. For example, DATA time TYPE t defines a data object named time with a type t and a length of 6 characters.
