  2. From the right to the left in the order of the tables:
    1.
    b is joined with c.
    2.
    b is joined with a.
  3. From the top to the bottom in the order of the on conditions 1.
    b is joined with c
    2.
    a is joined with b
  4. From the bottom to the top in the order of the on conditions:
    1.
    a is joined with b
    2.
    b is joined with c

Answer(s): C

Explanation:

The nested join is evaluated from the top to the bottom in the order of the ON conditions. This means that the join expression is formed by assigning each ON condition to the directly preceding JOIN from left to right. The join expression can be parenthesized implicitly or explicitly to show the order of evaluation. In this case, the implicit parentheses are as follows:

SELECT * FROM (a INNER JOIN (b INNER JOIN c ON b~c = c~c) ON a~b = b~b) This means that the first join expression is b INNER JOIN c ON b~c = c~c, which joins the columns of tables b and c based on the condition that b~c equals c~c. The second join expression is a INNER JOIN (b INNER JOIN c ON b~c = c~c) ON a~b = b~b, which joins the columns of table a and the result of the first join expression based on the condition that a~b equals b~b. The final result set contains all combinations of rows from tables a, b, and c that satisfy both join conditions.

Which extensibility type does SAP recommend you use to enhance the existing UI for an SAP Fiori app?

  1. Key user
  2. Classic
  3. Side-by-side
  4. Developer

Answer(s): D

Explanation:

According to the SAP clean core extensibility and ABAP cloud topic, SAP recommends using developer extensibility to enhance the existing UI for an SAP Fiori app. Developer extensibility allows you to use the UI adaptation editor in SAP Web IDE to modify the UI layout, add or remove fields, and bind them to the data model. You can also use the SAPUI5 framework to create custom controls, views, and controllers. Developer extensibility is based on the in-app extensibility concept, which means that the extensions are part of the same application and are deployed together with the app. Developer extensibility requires developer skills and access to the source code of the app.

What are some features of a unique secondary key?
Note: There are 2 correct answers to this question.

  1. It is created when a table is filled.
  2. It is updated when the modified table is read again.
  3. It is created with the first read access of a table.
  4. It is updated when the table is modified.

Answer(s): C,D

Explanation:

A unique secondary key is a type of secondary key that ensures that the key combination of all the rows in a table is unique. A unique secondary key has two purposes: firstly, to speed up access to the table, and secondly, to enforce data integrity.
It is created with the first read access of a table: This is true. A unique secondary key is created when an internal table is filled for the first time using the statement READ TABLE or a similar statement. The system assigns a name and an index to each row of the table based on the key fields.
It is updated when the modified table is read again: This is false. A unique secondary key does not need to be updated when the internal table content changes, because it already ensures data uniqueness. The system uses a lazy update strategy for non-unique secondary keys, which means that it delays updating them until they are actually accessed.
You cannot do any of the following:
It is created when a table is filled: This is false. As explained above, a unique secondary key is created only with the first read access of a table.
It is updated when the modified table is read again: This is false. As explained above, a unique secondary key does not need to be updated when the internal table content changes.
