Hi Professional ,

Create Table,

CREATE TABLE abc
(num int)



Insert Into

insert into abc values (1010)
insert into abc values (111)
insert into abc values (99)
insert into abc values (0)



SELECT 'D'+ CAST(num AS NVARCHAR) FROM abc



Now I am getting Result as below,
D1010
D111
D99
D0

But I have to show result as like below,
D1010
D1110
D9900
0

So please suggest me how to do this ?

Regards,
KRAj

SELECT 'D' + LEFT(CAST(num AS VARCHAR(4))+'0000',4) 
FROM abc

SELECT ISNULL('D' + LEFT(CAST(NULLIF(num,0) AS VARCHAR(4))+'0000',4),'0')
FROM abc

Or like this:


SELECT CASE num WHEN 0 THEN '' ELSE 'D' END +
RIGHT(num*POWER(10, 3-FLOOR(LOG10(CASE num WHEN 0 THEN 1 ELSE num END))), 4)
FROM abc




What??? :-P


My mantra: No loops! No CURSORs! No RBAR! Hoo-uh!

My thought question: Have you ever been told that your query runs too fast?

My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.


Need to UNPIVOT? Why not CROSS APPLY VALUES instead?
Since random numbers are too important to be left to chance, let's generate some!
Learn to understand recursive CTEs by example.
Splitting strings based on patterns can be fast!
