Comprehensive and Detailed Explanation from Exact Extract:

A. Automatic execution → ✅ A constructor (CONSTRUCTOR) is automatically invoked when an instance of a class is created.

B. Importing parameters → ✅ Constructors can have importing parameters to initialize the object with values.

C. First method called by client → ❌ Not correct, because constructors are called by the system, not the client explicitly.

D. Returning parameters → ❌ Constructors cannot return values; they only set up the object.

This behavior is consistent across ABAP Cloud OOP classes, ensuring encapsulated initialization logic.

Comprehensive and Detailed Explanation From Exact Extract:

The EXTRACT_YEAR, EXTRACT_MONTH, and EXTRACT_DAY functions in ABAP SQL are SQL built-in functions used for extracting date components. These functions are only supported for timestamp-capable or date-capable fields.

According to the ABAP CDS Development Guide and SAP HANA SQL capabilities available to ABAP SQL via CDS or native SQL:

DATS (ABAP Dictionary data type for dates) is fully supported for extract functions.

TIMESTAMP and UTCLONG are also supported since they represent full date-time values and are mapped internally to TIMESTAMP with time zone considerations.

TIMS is a time-only type and is not valid for extract date functions.

TIMN is for time periods and is also not valid for extracting year, month, or day.

Therefore:

Option B (UTCLONG) – correct

Option C (TIMESTAMP) – correct

Option D (DATS) – correct

Options A (TIMS) and E (TIMN) – incorrect

ABAP Open SQL allows CAST( … AS … ) to SQL/Dictionary-compatible types such as CHAR(n) and DEC(p,s), which are valid (A, D).

ABAP numeric integer target is accepted as I in Open SQL casting context on recent ABAP platform levels (E).

N(8) is not a valid SQL cast target (NUMC is an ABAP elementary type, not an SQL cast target), and plain INT8 (without the ABAP type namespace form) is not a generally valid SQL type literal in Open SQL (so B and C are rejected on standard ABAP Cloud systems).

RAP and ABAP Cloud emphasize pushdown with typed SQL expressions and strict static checks; only released, database-compatible types are permitted in CAST, enforced by the language and static checks.
