Question

What is the output of the SQL statement?
SELECT MID('CUET2024',2,5)?

• A. UET2
• B. ET202
• C. UET20
• D. CUET2

Answer 1

The Correct Option is C

Step 1: Understand the MID function

The MID() function in SQL is used to extract a substring from a string. The syntax is MID(string, start, length), where:

- string is the original string.

- start is the position where the extraction begins. Positions are 1-based.

- length is the number of characters to extract.

 

Step 2: Applying MID to the given string

In this case, the SQL statement SELECT MID('CUET2024',2,5) is evaluated.

- String: 'CUET2024'

- Start Position: 2 (the character at position 2 is 'U')

- Length: 5

Step 3: Extract the Substring

Starting from position 2 (which corresponds to 'U') and extracting 5 characters gives us the substring 'UET20'.

Output

The result of the SQL statement is UET20.

Correct Answer: UET20

Answer 2

SQL Function Analysis: The MID() function extracts a substring from a string. The syntax is MID(string, start_position, length).

Breaking down the query: MID('CUET2024', 2, 5)

• String: 'CUET2024' (positions: 1=C, 2=U, 3=E, 4=T, 5=2, 6=0, 7=2, 8=4)
• Start at position: 2 (the 'U')
• Extract 5 characters: From position 2 through 6 (U,E,T,2,0)

Evaluating the options:

(1) UET2 → Incorrect (only 4 characters)

(2) UET20 → Correct (positions 2-6: U,E,T,2,0)

(3) ET202 → Incorrect (starts at position 3 instead of 2)

(4) CUET2 → Incorrect (starts at position 1 instead of 2)

Character Position Mapping:

C U E T 2 0 2 4 1 2 3 4 5 6 7 8

The correct output is (3) UET20, as it correctly extracts 5 characters starting from position 2.
