What will be the output of
DECLARE @string VARCHAR(20) = ‘Hello how r u?’
SELECT STUFF(REPLICATE(‘,’ + LEFT(@string,10),LEN(LEFT(@string,10)) –
LEN(REPLACE(LEFT(@string,10), ‘o’, ”))),1,1,”)
Correct
[CODE]SELECT LEFT(@string,10) [/CODE] returns [B]Hello how [/B] [CODE]SELECT LEN(LEFT(@string,10)) – LEN(REPLACE(LEFT(@string,10), ‘o’, ”))[/CODE] returns [CODE]2[/CODE] We are now replicating the word [B]Hello how [/B] [B]2 times[/B] by using [CODE]SELECT REPLICATE(‘,’ + LEFT(@string,10),LEN(LEFT(@string,10)) – LEN(REPLACE(LEFT(@string,10), ‘o’, ”))) [/CODE] which returns [B],Hello how ,Hello how [/B] The stuff function removes the leading[B] ,[/B] [CODE]SELECT STUFF(REPLICATE(‘,’ + LEFT(@string,10),LEN(LEFT(@string,10)) – LEN(REPLACE(LEFT(@string,10), ‘o’, ”))),1,1,”)[/CODE] resulting [B]Hello how ,Hello how [/B]

5. Question
What will be the output of the below TSQL Script?
DECLARE @t TABLE(Chars VARCHAR(20))
INSERT INTO @T SELECT ‘D’ UNION ALL SELECT ‘N’ UNION ALL SELECT ‘F’
SELECT Chars Data
FROM @T
FOR XML PATH(”)
Correct
The FOR XML Path transforms the rows to columns but returns the result in XML format XML_F52E2B61-18A1-11d1-B105-00805F49916B —————————————————— DNF

6. Question
What will be the output of the below TSQL Script?
DECLARE @String VARCHAR(MAX)
SET @String = ‘DNF’
;WITH numberCTE AS
(
SELECT 1 AS Rn
UNION ALL
SELECT Rn+1 FROM numberCTE WHERE Rn
Correct
String DNF will be split into individual characters like D N F row wise. The numberCTE generates the sequential numbers based on the length of the string. It will be 3 here. The substring function [CODE]SUBSTRING(@String,rn,1)[/CODE] will accept the numbers one by one and will return individual characters based on the Rn value. final output [CODE]Characters ————- D N F[/CODE]

7. Question
What will be the output of the following?
DECLARE @String VARCHAR(MAX)
DECLARE @Noise TABLE(Noise VARCHAR(100),ReplaceChars VARCHAR(10))
SET @String = ‘hello! DNF.!’
INSERT INTO @Noise(Noise,ReplaceChars)
SELECT ‘!’,SPACE(1) UNION ALL SELECT ‘@’,SPACE(1) UNION ALL
SELECT ‘#’,SPACE(1) UNION ALL SELECT ‘$’,SPACE(1) UNION ALL
SELECT ‘%’,SPACE(1) UNION ALL SELECT ‘^’,SPACE(1) UNION ALL
SELECT ‘&’,SPACE(1) UNION ALL SELECT ‘*’,SPACE(1) UNION ALL
SELECT ‘(‘,SPACE(1) UNION ALL SELECT ‘)’,SPACE(1) UNION ALL
SELECT ‘{‘,SPACE(1) UNION ALL SELECT ‘}’,SPACE(1) UNION ALL
SELECT ‘‘,SPACE(1) UNION ALL
SELECT ‘:’,SPACE(1)
SELECT @String = REPLACE(@String, Noise, ReplaceChars) FROM @Noise
SELECT @String Data
Correct
The code removes the special characters (in this case !) and returns the string. The Replace function does the special character removal operation.

UNION ALL
SELECT Rn+1 FROM numberCTE WHERE Rn
Correct
Length of data is 10 [CODE]DECLARE @Data VARCHAR(MAX) SET @Data = ‘hello!DNF.’ SELECT LEN(@Data) /* 10 */[/CODE] The Recursive CTE generates numbers between 1 to 10

17. Question
What is the value for SIGN(NVL(-16,0))?
Correct
Here Let see how we calculate these values. Consider we have the following : SIGN(ABS(NVL(-75,0))) Just like mathematics we should take it from the inner brackets. So first step will be, NVL(-75,0) = -75 Now, next bracket ABS(-75) = 75 //ABS always take positive Finally SIGN(75) = 1 If SIGN(>1) = 1, SIGN(
