You own table DEPARTMENTS, referenced by views, indexes, and synonyms.
Examine this command which executes successfully:
DROP TABLE departments PURGE;
Which three statements are true?
A: This is true. Using PURGE in the DROP TABLE command will permanently remove the table and its dependent objects so that it cannot be recovered, and the action cannot be rolled back.
B: This statement is true. Dropping the base table will result in the removal of all views that are based on the DEPARTMENTS table.
C: This statement is false. The PURGE option removes the table and does not just delete rows.
D: This statement is true. The DROP TABLE command will remove the DEPARTMENTS table from the database.
E: This statement is true. When a table is dropped, all synonyms for that table are also removed.
F: This statement is true. Dropping a table will automatically drop all indexes associated with the table.
Examine this description of the PRODUCTS table:
You successfully execute this command:
CREATE TALE new_prices(prod_id NUBER(2),price NUMBER(8,2));
Which two statements execute without errors?
In the context of the MERGE statement, certain syntax rules and logical sequences must be observed:
Option B:
Correct use of the MERGE statement includes specifying the source and target correctly, and handling cases for matched and unmatched rows. This option properly structures the MERGE command with correct conditions for both matching (on prod_id) and actions (insert for unmatched, and delete under certain conditions for matched rows).
Option D:
While this option has a typographical error with 'WHEN NOT NATCHED', assuming it's intended as 'WHEN NOT MATCHED', it correctly describes the action for inserting into new_prices when no match is found in the target table based on the condition specified (product cost less than 200).
Options A and C contain syntax errors and logical contradictions (such as attempting to both update and delete in the same matched clause without proper separation or conditions), which are not allowed in a single WHEN MATCHED clause in Oracle SQL.
Examine the data in the NEW_EMPLOYEES table:
Examine the data in the EMPLOYEES table:
You want to:
1. Update existing employee details in the EMPLOYEES table with data from the NEW EMPLOYEES
table.
2. Add new employee detail from the NEW_ EMPLOYEES able to the EMPLOYEES table.
Which statement will do this:
The correct answer to perform the specified update and insert operations is to use the MERGE statement, which is designed to facilitate such 'upsert' operations (update or insert).
A . The syntax is incorrect; the WHERE clause is not used with MERGE.
B . This is the correct syntax and use of the MERGE statement. It uses the ON clause to specify the join condition, and it provides actions for WHEN MATCHED and WHEN NOT MATCHED situations.
C . The keywords FOUND and NOT FOUND are not valid in the context of the MERGE statement in Oracle SQL.
D . Similar to option A, the syntax is incorrect because MERGE uses an ON clause, not a WHERE clause, and the keywords FOUND and NOT FOUND are incorrect.
The correct syntax of a MERGE statement includes defining a condition using the ON clause to determine how rows from the source and target tables are matched, then specifying the actions for when rows match (WHEN MATCHED) and when they do not match (WHEN NOT MATCHED).
You create a table by using this command:
CREATE TABLE rate_list (rate NUMBER(6,2));
Which two are true about executing statements?
The behavior of data insertion into a table with a specific numeric format in Oracle Database 12c can be explained as follows:
A . INSERT INTO rate_list VALUES (-.9) inserts the value as -.9: This is correct. The value -.9 is within the precision defined by the table column (NUMBER(6,2)), where 6 is the total number of digits (including both sides of the decimal point), and 2 is the number of digits after the decimal point.
E . INSERT INTO rate_list VALUES (0.551) inserts the value as .55: Oracle rounds the number to the nearest value that fits the specified scale of 2. Thus, 0.551 rounds down to 0.55.
Oracle Database SQL Language Reference 12c, particularly sections on data types and numeric precision.
Which two are true?
The CONCAT function and FLOOR function in Oracle SQL have specific behaviors:
A . CONCAT function joins two or more character strings into one string, making this statement true.
B . FLOOR function returns the largest integer that is less than or equal to the specified number, making this statement true.
C . While CONCAT can join two strings together, this statement is incomplete as it can join more than two.
D . INSTR can find the offset of a substring within a string, not just a single character.
E . INSTR starts searching the string from position 1 in Oracle SQL, not position 0.
F . FLOOR does return the largest integer less than or equal to the specified number, but it can be any integer, not just positive ones.
