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')
Result
India is my country
Pakistan is my country
Ex 1: Sql Server replace function similar to Oracle Translate Replace function
Declare @Str varchar(100)
set @Str='Think You'
print @Str
print replace(@Str,'i','a')Result
Think 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.

Difference between a "where" clause and a "having" clause?

Editorial / Best Answer
Answered by: Ankush Sharma
Answered On : Sep 13th, 2011Though 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

Fff0explanation :-1 is internally represented as all 1's. When lEFT shifted four times the least significant 4 bits are filled with 0's.The %x format specifier specifies that the integer value be printed as a hexadecimal value
Depending on the machine implementation it will result in FFFFFF0 (for 32bit ) or FFF0 (16 bit )
Threeexplanation :the default case can be placed anywhere inside the loop. It is executed only when all other cases doesn't match.
loop? or block?
the output will be three because when execution takes place ,inside the switch the corresponding case 3(since i=3)is selected and as there is a break statement after it, it cmes out of the loop.
Viii) main(){ char *p; printf("%d %d ",sizeof(*p),sizeof(p));}
1 2explanation:the sizeof() operator gives the number of bytes taken by its operand. P is a character pointer, which needs one byte for storing its value (a character). Hence sizeof(*p) gives a value of 1. Since it needs two bytes to store the address of the character pointer sizeof(p) gives 2.
ans is->1 4 as *p will give the value and char is 1 byte but p will print 4 because its an address so it will print 4 bytes
ans is 1 & 2 bcoz *p is pointing to some char data which must be 1 byte and size(p) is 2 byte bcoz it is holding the address which is an integer

So the expression i++ && j++ && k++ is executed first. The result of this expression is 0 (-1 && -1 && 0 = 0). Now the expression...

2(glen-2)=jason
glen+2=2(gason-2)
glen+2=2jasong-4
so glen=6, jason=8

1. Monkeys and bananas:Suppose 8 monkeys take 8 minutes to eat 8 bananas. (a) How many minutes would it take 3 monkeys to eat 3 bananas?My thought : 8 monkeys takes 8 minutes to eat 8 bananas So 1 monkey will take 8 minutes to eat 1 bananas So 3 monkey will take 8 minutes to eat 3 bananas.
8 monkeys take 8 mins to eat 8 bans.
so, 1 monkey take 8 min to eat 1 banana.
if 1 monkey eat for 48 mins it will eat 6 bananas
there are 48 bananas, so we need 8 monkeys giving 6 bananas each.
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
(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 =1
This gives px = 1/8x = 8 years,
2. This gives, total life, x = 64 years
3. One half of this is active age. So its 32 years.
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...
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...
I get 366.67 miles.Let v = train full velocityLet d = distanceCase 1 - train goes (1 hour * v) + (2 hours * 3 v / 5) = d Therefore d = v * 2.2 hoursCase 2 - train covers 50 miles...
Case first : let us assume speed to train be x miles/hours Total distance travelled in case 1 = x*1 + 3x/5*2 = 11x/5 milesCase 2 : Total distance travelled in case 2 = x+50 + 3x/5*(2-45/60) = 50 +7x/4...
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...
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 =...

Speed at which two trains travel towards each other = 60+60 = 120 miles/hour.Total length to be covered = (1/6)+(1/6) = 2/6 mile.Time to taken to cover 2/6 mile at speed of 120 miles/hour is.....(2/6)/120 = 1/360 hour = 10 seconds.
Hi, I am doing B.E IIyr.I ve doubt how come you could say that the velocity is 120mile/hr......actually it appears to be twice the velocity of each but actually.....so are you tr...

From condition 1 and 3 we can say that the prisoner tried to escape inmethods a,b,c in order on 3 consecutive days. From conditions 2 and 3 andthe order for a,b,c we can say that the order for thursday and friday wase, d in order.So, the order from monday through friday will be a,b,c,e,d.
the order is: a,b,c,d,e.
ans- a,b,c,d,e
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.
The time taken to cross the poles from 1st pole to 10th pole(i.e, 9 poles ) is 10 sec.
Then the time taken to cross 1 pole is 10/9 sec.
Therefore the time taken to cross the poles from 1st pole to 15th pole(i.e, 14 poles) is (10/9)*14=15.55 sec.

The clock strikes 1 sec for each intreval......tat means.....
if it is goin to strike for 10 sec.....it will be 11(am or pm)....
11 hrs after clock strikes for 10 sec means....11 hrs after 11
tat ia after 22 hrs
I guess......AM I RIGHT?
Sinc there are 10 sec betwn 11 hrs(11 hrs = 10 intervals), 1 sec is betwn 2 hrs.. so they meet after 2 hrs.
as one had won 12 games but still gave other 8 chocolates therefor total number if games is 12+12 +8=32 ans
