Oracle Database SQL 認定 1z1-071 試験問題 (Q420-Q425):

質問 # 420
Which two are true?

A. FLOOR returns the largest positive integer less than or equal to a specified number.
B. INSTR finds the offset within a string of a single character only.
C. CONCAT joins two or more character strings together.
D. CONCAT joins two character strings together.
E. FLOOR returns the largest integer less than or equal to a specified number.
F. INSTR finds the offset within a character string, starting from position 0.

正解：C、E

解説：
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.

質問 # 421
Which two statements are true about the rules of precedence for operators?

A. The + binary operator has the highest precedence in an expression in a SQL statements.
B. NULLS influence the precedence of operators in an expression.
C. Arithmetic operators with equal precedence are evaluated from left to right within an expression.
D. The concatenation operator || is always evaluated before addition and subtraction in an expression.
E. Multiple parentheses can be used to override the default precedence of operators in an expression.

正解：C、E

解説：
A). True, arithmetic operators of equal precedence are evaluated from left to right within an expression, according to the standard SQL operator precedence. B. True, multiple parentheses can be used in an expression to change the order of operations and override the default precedence of operators.
C, D, and E are not correct because: C. The + binary operator does not have the highest precedence; multiplication and division have higher precedence in SQL. D. NULLS do not influence the precedence of operators in an expression; they may affect the result of an operation but not the order in which operators are evaluated. E. The concatenation operator (||) has lower precedence than arithmetic operators in SQL expressions.

質問 # 422
You want to display the date for the first Monday of the next month and issue the following command:

What is the outcome?

A. In generates an error because fmand double quotation marks should not be used in the format string.
B. In generates an error because TO_CHARshould be replaced with TO_DATE.
C. In generates an error because rrrrshould be replaced by rrin the format string.
D. It executes successfully but does not return the correct result.
E. It executes successfully and returns the correct result.

正解：E

質問 # 423
Table ORDER_ITEMS contains columns ORDER_ID, UNIT_PRICE and QUANTITY, of data type NUMBER Statement 1:
SELECT MAX (unit price*quantity) "Maximum Order FROM order items;
Statement 2:
SELECT MAX (unit price*quantity "Maximum order" FROM order items GROUP BY order id; Which two statements are true?

A. Both statements will return NULL if either UNIT PRICE or QUANTITY contains NULL,
B. Statement 2 may return multiple rows of output.
C. Statement 2 returns only one row of output.
D. Statement 1 returns only one row of output.
E. Both the statement given the same output.

正解：B、D

解説：
Analyzing the given SQL statements on the ORDER_ITEMS table:
* D. Statement 2 may return multiple rows of output: Statement 2 groups the results by ORDER_ID, which means it calculates the maximum UNIT_PRICE * QUANTITY for each ORDER_ID, potentially returning multiple rows depending on the number of unique ORDER_IDs in the table.
* E. Statement 1 returns only one row of output: Statement 1 computes the maximum product of UNIT_PRICE and QUANTITY across all entries in the ORDER_ITEMS table, returning a single row with the maximum value.
Incorrect options:
* A: Since Statement 2 groups by ORDER_ID, it does not necessarily return just one row; it returns one row per ORDER_ID.
* B: These statements do not yield the same output; Statement 1 returns a single maximum value, while Statement 2 returns the maximum value per ORDER_ID.
* C: If either UNIT_PRICE or QUANTITY is NULL, the product for that row will be NULL, but the MAX function ignores NULL values in its calculation unless all rows are NULL, in which case it returns NULL.

質問 # 424
Which three statements are true regarding indexes?

A. A UNIQUE index can be altered to be non-unique.
B. An update to a table can result in no updates to any of the table's indexes.
C. When a table is dropped and is moved to the RECYCLE BIN, all Indexes built on that table are permanently dropped.
D. A table belonging to one user can have an index that belongs to a different user,
E. An update to a table can result in updates to any or all of the table's indexes.
F. A SELECT statement can access one or more indices without accessing any tables.

正解：B、C、D
