I have a table in a SQL Server 2000 database with a column with several entries like 01-03, 04-05. The first 2 digits are the room number and the last two digits are the bed number.
I want to replace the 01-05, 03-07 etc. with only the bed number. So only the last two charcters have to be in the column.
How do I accomplish this?
Sample data is:
In the column [Bed] with values:
22-01
08-01
09-03
01-16
Result has to be:
01
01
03
16
RIGHT should solve your problem:
SELECT RIGHT(RTRIM(Bed), 2) FROM tbl

There is no error, but the results show the values excluding the row that meets both conditions. The result shows 3, in fact, it should be 4 excluding data that has 22 for age and UK for the country. Any idea why the result is 3, not 4?
SELECT COUNT(*) FROM CUSTOMERS WHERE CUSTOMERS.AGE = '22' OR CUSTOMERS.COUNTRY = 'UK';
You have two customers at the age of 22 and 2 residing in the UK.
This is actually a correct result here - how on earth do you come to the conclusion that you have four people meeting that criteria? If more than one point matches for a database entry, it will only count as one for the result, since it's still the same database entry.

Looking for ways to convert numbers to characters.
For SqlServer (which you didn't specify)
SELECT NCHAR(numval+9311);
Explanation:
the "enclosed alphanumerics" are at Unicode codepoints 9312 ① through 9331 ⑳. A "numval" of 1 becomes 9312 before passing it to NCHAR
the NCHAR function converts from codepoint value to corresponding character
Warning:
This only works for values from 1 to 20 (there is no "circled number 21" and while there does exist a "circled digit zero" ⓪, that's at 9450)

I have to concatenate 10 different fields in the same table. After the field concatenated, I need to eliminate the space between all characters. 30,000
records.
CUSTOMER # FIELD 1 FIELD 3 FIELD 4 FIELD 5 FIELD 6 FIELD XX
,TO BE OR NOT, /THAT IS/ /THE Q/ OR NOT THE_ QUESTION
So, it would like like:
,TOBEORNOT,/THAT IS//THEQ/ORNOTTHE_QUESTION
With concat and replace:
select
replace(concat(field1, field2,....), ' ', '')
from customer
To count the characters use len:
select
len(replace(concat(field1, field2,....), ' ', '')) counter
from customer

Want one data row set with y (b) and one data row set with s (b).

EDIT: SELECT DISTINCT b FROM table;

I have got table like below after sorting in SQL:
M_ID
-----
2013/01
2013/02
2013/03
2013/04
2013/05
2013/06
Now I want to assign each entries a particular value like below
M_ID Days
--------------
2013/01 20
2013/02 30
2013/03 40
2013/04 50
2013/05 60
2013/06 70
So, can you please let me know how to do that in SQL Query?
Do you mean something like this (presuming sql-server)?
SELECT M_ID,
Days = (ROW_NUMBER()OVER(ORDER BY M_ID) + 1) * 10
FROM dbo.TableName
