This is example of the column "Amount" i am working on. I need to remove all '+' and '-' and all leading zeros, then convert to decimal. There are also cases when there is only zeros present and i am not sure what is the best approach for it. Is there a better solution? Please help on this.
Amount
-0000211
+0000101
+0000000
+0000013
CAST(CAST(CAST(Amount as INT) AS varchar(8)) as decimal(8,2)) from payment_table;
use abs() to remove +/- and 0, and then use cast() to cast to decimal.
select CAST( ABS(Amount) as DECIMAL(8,2)) as ret_Amount -- this will return 211.00

How to remove the zeros
select CONVERT(varchar, CAST( -3563338 AS money), 1)
Output
-3,563,338.00
Expected Output
-3,563,338
Use FORMAT:
SELECT FORMAT(-3563338,'#,###,##0')
-3,563,338
The money type output includes a decimal component for change. But, since you don't want to see that it might be easier to just use FORMAT instead.
Try below - using replace() function
select replace(CONVERT(varchar, CAST( -3563338 AS money), 1),'.00','')
this will work:
select TO_CHAR(-3563338.00,'99999999') from dual;
I am trying to convert a varchar to a percentage with a decimal. For example, my report is returning 13590 as a result for a rate, which I would like to have a result of 13.590%. I can't seem to get this to work, any help would be appreciated.
You can use Arithmetic operator inside your query, e.g.
SELECT (report / 100) as rate FROM MyTable;.
If the % is needed, look at the CONCAT function.
Not a very elegant solution, and will drop trailing zeros
SELECT cast(cast(columnA as float) / cast(1000 as float) as varchar(20)) + '%'
I want to convert my decimal SQL query result in percent. Example I have a 0.295333 I want it to be 30% and if I have a 0.090036 I want it to be 9%.
This is what I have so far.
(100 * (sample1/ sample2) ) as 'Percent'
I also tried this one but the problem is result comes with ".00" and I don't know how to remove the decimal.
cast (ROUND(100 * (sample1 / sample2),0) As int ) as 'Percent'
Try with the below script..
cast (100 * Round((sample1 / sample2),2) As int ) as 'Percent'
So as some of the comments pointed out you may need to pay attention to your datatype if one or both of the original columns that you get your decimal from are integer.
One easy way of dealing with that is something like this:
ColA * ColB * 1.0 which will make sure that your integers are treated as decimals
So if you have SQL Server 2012+ you can use Format and not mess with rounding at all. Like this FORMAT(YourDecimal,'#%'), yep that simple.
;WITH cteValues AS (
SELECT 0.295333 as OriginalValue
UNION ALL
SELECT 0.090036 as OriginalValue
)
SELECT
OriginalValue
,FORMAT(OriginalValue,'#%') as PercentFormat
FROm
cteValues
If you are pre 2012 and do not have format an easy way is to round to the 100th then times by 100 and cast as int CAST(ROUND(YourDecimal,2) * 100 AS INT)
;WITH cteValues AS (
SELECT 0.295333 as OriginalValue
UNION ALL
SELECT 0.090036 as OriginalValue
)
SELECT
OriginalValue
,CAST(ROUND(OriginalValue,2) * 100 AS INT) as PercentInt
FROm
cteValues
Because an INT cannot by definition have decimal places, if you are receiving .00 with the method similar to this or the one you have tried, I would ask the following.
Are you combining (multiplying etc.) the value after casting with another column or value that may be decimal, numeric, or float?
Are you looking at the query results in a program outside of SSMS that could be formatting the results automatically, e.g. Excel, Access?
Address your assumptions first.
How does ROUND work? Does it guarantee return values and if so, how? What is the precedence of the two columns? Does Arithmetic operators influence the results and how?
I only know what I do not know, and any doubt is worth an investigation.
THE DIVIDEND OPERATOR
Since ROUND always returns the higher precedence, this is not the problem. It is in fact the divide operator ( / ) that may be transforming your values to an integer.
Always verify the variables are consistently of one datatype or CAST if either unsure or unable to guarantee (such as insufficiently formatted. I.e. DECIMAL(4,2) instead of required DECIMAL(5,3) ).
DECLARE #Sample1 INT
, #Sample2 DECIMAL(4,2);
SET #Sample1 = 50;
SET #Sample2 =83.11;
SELECT ROUND( 100 * #Sample1 / #Sample2 , 0 )
Returns properly 60.
SELECT ROUND( 100 * #Sample2 / #Sample1 , 0)
Incorrectly turns variables into integers before rounding.
The reason is that DIVIDE - MSDN in SQL may return the higher precedence, but any dividend that is an integer returns another integer.
UPDATE
This also explains why the decimal remains after ROUND...it is of higher precedence. You can add another cast to transform the non-INT datatype to the preferred format.
SELECT CAST( ROUND( <expression>, <Length>) AS INT)
Note that in answering your question I learned something myself! :)
Hope this helps.
For presentations sake I have a value that I want to show to only two decimal places before converting to varchar
select '£' + cast(round(amount,2) as varchar (10))
This works fine and would display the result as, say, £300.00. However the 'amount' also needs to be divided by 100 as part of the query. When I add that in to the code...
select '£' + cast(round(amount/100,2) as varchar (10))
..it displays as £3.000000. Is there any way to remove the extra 0s so only two are shown after the decimal point?
Just use format():
select '£' + format(amount, 2)
This also adds in commas, which seems desirable.
If you don't want the commas, then don't use round(), cast to a decimal type:
select '£' + cast(cast(round(amount, 2) as decimal(10, 2)) as varchar(10))
round() does change the value, but it doesn't change the storage mechanism. The cast( . .. as varchar) doesn't know -- or care -- how many significant values are in the result.
EDIT (for SQL Server):
Instead of format() you can use the str() function:
select '£' + ltrim(str(amount, 10, 2))
Or the last method of converting to a decimal before the conversion.
What is the datatype of amount column? cast the round part into float
select '£' + cast(round(cast(8375.8734/100 as float),2) as varchar (100));
Result is
£83.76
Also this should done in the front end application and not in sql
How do I code format the return data in 2 decimals and with percentage format like 100.00% or 67.39% instead of 100.000000 or 67.391304?
SUM(qa.scripting1+qa.conduct1+qa.conduct2+qa.conduct3)*100.0/46 as 'C%'
I tried ROUND() but I got the error stating that the round function requires 2 to 3 arguments?
ROUND(SUM(qa.scripting1+qa.conduct1+qa.conduct2+qa.conduct3)*100.0/46) as 'C%'
Thanks!
You can convert to a decimal your original value:
CONVERT(VARCHAR(20), CONVERT(DECIMAL(18,2), SUM(qa.scripting1+qa.conduct1+qa.conduct2+qa.conduct3)*100.0/46) ) + '%' as 'C%'
The first number in the decimal represents the number of digits in the number including decimal places, and the second number represents the number of decimal places.
You should pass number of decimals in second parameter to round function. For formating you can cast number to money and then cast to varchar:
select cast(cast(ROUND(SUM(123.12321)*100.0/46, 2) as money) as varchar) + '%'
Using Round and Cast will work. First round to 2 decimal places then convert to a decimal with 2 places to truncate the excess zeros.
select cast(Round(yourValue, 2) as decimal(18,2))
Sql Fiddle
You can use Format function
select FORMAT(100.0000, 'N' , 'en-us')
returns 100.00
and
select FORMAT(67.391304, 'N' , 'en-us')
returns 67.39
EDIT
In version below 2012 you can do this
SELECT CAST(67.391304 AS NUMERIC(10, 2))
returns 67.39
You can just do:
select FORMAT(0.391304, '##0.00%')
But keep in mind that it implicitly multiplies by 100, so the above will display as 39.13%.
