Why can a "group by" or "order by" clause be expensive to process?
psingla

Group by: It clubs all the similar rows and display only the distinct data so here clubing and displaying distinct data is an overhead.Order by: It sorts the data either in ascending order or in desending order as specified in the query. Sorting the data is an overhead.

What is the difference between "translate" and "replace"?
Read Best Answer
Editorial / Best Answer
jayaprakash.raman- Member Since Apr-2007 | Apr 24th, 2007
Please refer that here we are discussing about Sql Server only. There is no function named 'Translate' in Sql Server. 'Translate' function exists in Oracle for translating a single character to some other character.
Replace fucntion in Sql server is used to replace a string as well as character to another string or character. No need to have a seperate function like Transalate in Oracle:
Find below the examples to get the clear idea:
Ex 1: Sql Server replace function similar to Oracle Replace function
Declare @Str varchar(100)set @Str='India is my country'
print @Str
print replace(@Str,'India','Pakistan')
ResultIndia is my country
Pakistan is my country
Ex 1: Sql Server replace function similar to Oracle Translate Replace functionDeclare @Str varchar(100)
set @Str='Think You'
print @Str
print replace(@Str,'i','a')
ResultThink You
Thank You
Note: Please try to post Sql server questions only here. Ther is a seperate section available for Oracle. If we mix both, it will confuse the people who are specializing their skill in particular area. Thank you.jayaprakash.raman

Difference between a "where" clause and a "having" clause?
Read Best Answer
Editorial / Best Answer
Answered by: Ankush Sharma
- Sep 14th, 2011
Though the HAVING clause specifies a condition that is similar to the purpose of a WHERE clause, the two clauses are not interchangeable. Listed below are some differences to help distinguish between the two:
1. The WHERE clause specifies the criteria which individual records must meet to be selcted by a query. It can be used without the GROUP BY clause. The HAVING clause cannot be used without the GROUP BY clause.
2. The WHERE clause selects rows before grouping. The HAVING clause selects rows after grouping.
3. The WHERE clause cannot contain aggregate functions. The HAVING clause can contain aggregate functions.
for Example: if for an "Select" statement we use the "where" clause then the the result based on the "where" condition results and then we can use "group by" clause to arrange in some order, Now if we want to impose the condition on that group then we use "having" clause.
The main reason for using WHERE clause is to select rows that are to be included in the query. For example, assume table Test.Suppose I want the names, account numbers, and balance due of all customers from California and Los Angles. Since STATE is one of the fields in the record format, I can use WHERE to select those customers.
Using the code
Suppose I want the total amount due from customers by state. In that case, I would need to use the GROUP BY clause to build an aggregate query.Code- SELECT cusnum, lstnam, init
- FROM Test
- WHERE state IN ('CA', 'LA')
- CUSNUM LSTNAM INIT BALDUE
- ====== ============ ==== ========

- GROUP BY state
- ORDER BY state

- CO 58.75

Code- SELECT state,SUM(baldue)

Is java a fully object oriented programming or not? if not why?

Editorial / Best Answer
KanikaKG- Member Since Jul-2008 | Aug 4th, 2008
No. Java is not 100 % Pure OOP because of following three reasons:
1) It doesnot support Multiple inheritance.
2) It allows use of primitive data types which are not an objects.
3) It allows static methods to call without creating the instance.
This disobeys OOPs concepts

a] See you don't need to sum it up. since it's a knock out only 1 person emerges winner finally.So 15+1=16 Because after 15 matches finally we should have 15losers and 1winner.b]49.its always one less than no of players as perthe idea given above.

as matches played 15 times,each time 2 player.so the game will end when one is out.so next person come.again game will start.there shoul be a winner at end of the whole game so total number of players are 31.15*2+1

have?"
After pausing a moment, he replied, "Well! If I divide the coins into
two unequal numbers, then 37 times the difference between the two
numbers equals the difference between the squares of the two numbers."
The wife looked puzzled. Can you help the merchant's wife by finding
out how many gold coins?
">A rich merchant had collected many gold coins. He did not want anybodyto know about them. One day, his wife asked, "How many gold coins do wehave?"After pausing a moment, he replied, "Well! If I divide the coins intotwo unequal numbers, then 37 times the difference between the twonumbers equals the difference between the squares of the two numbers."The wife looked puzzled. Can you help the merchant's wife by findingout how many gold coins?
37(x-y) =x^2-y^2. You no that x^2-y^2=(x-y)(x+y).So (x-y) cancels on both sides to give x+y=37.so sum of unequal halves=37 which is the req answer.

the merchant is having n gold coins he divides it into x and y37times the difference is 37(x-y)the squares of the two numbers is x^2 and y^2 so 37(x-y)=X^2-Y^2 (X^2-Y^2 = ...

Glenn and Jason each have a collection of cricket balls. Glenn saidthat if Jason would give him 2 of his balls they would have an equalnumber; but, if Glenn would give Jason 2 of his balls, Jason would have 2times as many balls as Glenn. How many balls does Jason have?
1. G+2=j-22. 2(G-2)=J+2.solve these 2 to getJ=14

Vacation timeIt was vacation time, and so I decided to visit my cousin's home. What a grand time we had! In the mornings, we both would go for a jog. The evenings were spent on the tennis court. Tiring as these activities were, we could manage only one per day, i.e., either we went for a jog or played tennis each day. There were days when we felt lazy and stayed home all day long. Now, there were 12 mornings when we did nothing, 18 evenings when we stayed at home, and a total of 14 days when we jogged or playedtennis. For how many days did I stay at my cousin's place?
Use sets and venn diagram to solve such questions.a,b ,aub,anb etc.12=tennis+leave18=jog +leaveso jog-tennis=6again jog+tennis=14.so solve and get jog=10,leave=8,tennis=4.so tot=22

Old Man WrinkleMan Wrinkle spent one-fourth of his life as a boy, one-eighth as a youth, and one-half as an active man. If Man Wrinkle spent 8 years as an old man, then how many years did he spend as an active man?
(1/4)y+(1/8)y+(1/2)y =p; where y =total life time.y-p=8.since p=(14/16)ywe've y=64active age=32

In case the above solution confuses.....1. If x is total life(1/4)x+(1/8)x+(1/2)x+px =x, where p is the proportion of oldage.(1/4)+(1/8)+(1/2)+p =1This gives px = 1/8x = 8 years,2. This gives, total life, x = 64 years3. One half of this is active age. So its 32 years.

A farmer has C chickens. A sack of feed comes for 9 days. As the feedcost is increasing the farmer sells some chickens and retains 12 chicken. If he reduces thefeed quantity by 10% .Then he observes that the feed comes for 30 days. What is C?
C chickens can b fed for 9 days. So C chick can eat 1/9 in 1 day.So 1 chick can eat (1/9C) in one day. After his reduction one chick gets to eat only 90% of what it used to eat in one day.So new feed value=0.9*(1/9C) for 1day.but now he has only 12 chicks.that means as per new rule feed is suitable for 12 chicks for 30 days.i.e.0.9*(1/9C)*12*30=1. Solve to get C=36Ans:36

A train travels at a particular speed for a duration of one hour, after which one of its engine malfunctions reducing its speed to 3/5th of the actual speed before theoccurrence of fault in engine. It travels at this speed for 2 hours to reach at itsdestination. If the fault had occurred 50 miles later on, the train would have reachedits destination 45 minutes early. Find the distance traveled by the train.
Let the actual speed of train be X miles/hour. after fault its speed will be reduced to 3X/5 miles/hour. If we could find the speed of the train, we will get the solution!!!by seeing one can find that time difference( 45 minutes) occur between two cases, in the 50 miles distance traveled by the train at two different speeds(X and 3X/5).=> If the time taken to cover 50 miles at speed 3X/5 is 't' hours...

A man wearing a hat stands on a bridge across a river. At an instant his hat falls into the river and starts flowing along with the stream at the same speed of the stream.At the same instant the man jumps into the river and starts swimming in the directionopposite to the stream, like that he swims for 10 minute , then he turns back and starts swimming in the direction of the stream to retrieve the hat. He retrieves the hatunder another bridge which is 1000 yards away down the stream from the first bridge.What is the speed of the river?
Let the swimming speed of man be = a yds/min.speed of stream = b yds/min.Then the man swims at (a-b) yds/min. against the stream.and (a+b) yds/min in direction with the stream.Lets assume the man covered a distance of x in 10 min swim up the stream at speed (a-b).The time taken by him to cover the same distance down the stream at speed (a+b) is...=> 10(a-b)/(a+b)The total time of travel(being same...

money u spent on buying your hat, we both would have spent the same amount on buying
our items(together, i.e., 15 rupees).
(a) what is the cost of hat bought by A.
(b) The money A and B apent together.
">A and B are two friends, together they go out for shopping. A buys a hat and a suit,all together A spends 15 rupees. B buys a hat which costs same as the suit bought byA. B even buys a dress which cost her one rupee less than the cost of hat bought by A.B says to A that "If at all I had bought my hat by spending one and half times the money u spent on buying your hat, we both would have spent the same amount on buying our items(together, i.e., 15 rupees).(a) what is the cost of hat bought by A.(b) The money A and B apent together.
Lets say A spent x and y rupees on hat and suit respectively. from the conditions we can say B spent y and x-1 rupees on hat and dress respectively. From what B told to A we can write that.....=> x + y = 15 = (3/2)x + (x-1)=> (3/2)x + (x-1) = 15=> (5/2)x - 1 = 15=> (5/2)x = 16=> x = 16 * (2/5)=> x = 32/5 = Rupees 6.40 paise (a) answer is 6.40 Rupees.(b) Total A alone spent = x+y =15. B spent = y +...

There are 15 poles in a straight line each equally placed from each other. The time taken to reach the 10th pole after a man startswalking from 1st pole is 10 seconds. What is the time required to reach 15th pole.
Let any two poles be placed x units apart. Distance between 1st and 10th pole=(10-1)x=9x units.Distance between 1st and 15th pole=(15-1)x=14x units.If time taken to cover 9x units is 10 seconds, then time taken to cover 14x units is..... (10*14x)/9x = 15.55 seconds.
