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%.

Say if I need to round multiple numbers to 2 digits now, but I don't want to repeat using round(..., 2) or format(...).
Is there any method to set up the float numbers with 2 digits globally?
select cast(float_column as decimal(10,2))
from your_table
Declare the column or variable of type numeric(18, 2)
You can also use with the CONVERT function
select CONVERT(numeric(18, 2) , 5.54722)
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
I am calculating total hours/minutes but i would like to get rid off the decimals and only show something like this 2.00 hours or 2.5 hours etc. I am getting now something like this: 2.000000 and want only to limit to 2 decimals only.
select DATEDIFF(minute, Min(FullDatetime), Max(FullDatetime)) / 60.0 as hours
from myTable
where userid = 123
You can do it by rounding but the easiest is to format for output using FORMAT().
select FORMAT(DATEDIFF(minute, Min(FullDatetime), Max(FullDatetime)) / 60.0, 'N2') as hours
from myTable
where userid = 123
Helpful original documentation: here
try use
cast('values' as decimal(18,2)) --2 decimal place.
select Cast((DATEDIFF(minute, Min(FullDatetime), Max(FullDatetime)) / 60.0 as hours)as decimal(18,2))
from myTable
where userid = 123
There are a few options out there.
I prefer to use the following when no rounding is needed
FORMAT(value, 'N2')
SQL - Rounding off to 2 decimal places
how to get 2 digits after decimal point in tsql?
just use ROUND function such as : SELECT ROUND(columnName,decimals) from table
You could use STR or CONVERT function:
DECLARE #v NUMERIC(19, 6)
SET #v = 2.189189
SELECT STR(#v, 19, 2) AS Method1_Result_VARCHAR, CONVERT(NUMERIC(15, 2), #v) AS Method2_Result_NUMERIC
/*
Method1_Result_VARCHAR Method2_Result_NUMERIC
---------------------- ----------------------
2.19 2.19
*/
Note: First argument of STR function has float type and this means that 1) SQL Server will convert this argument from numeric to float and 2) method 1 uses a non-deterministic expression.
I run a query and all my numbers are coming out to 5 decimal points:
for example -
156713.55000
2103613.03000
2080.08000
is there a simple piece of code I can add into my code so the 'Cost' table results are to 2 decimal points?
Following example will help you.
With rounding:
select ROUND(55.4567, 2, 0)
-- Returns 55.4600
select CAST(55.4567 as decimal(38, 2))
-- Returns 55.46
Without rounding:
select ROUND(55.4567, 2, 1)
-- Returns 55.4500
select CAST(ROUND(55.4567, 2, 1) as decimal(38, 2))
-- Returns 55.45
or
Use Str() Function. It takes three arguments(the number, the number total characters to display, and the number of decimal places to display
Select Str(12345.6789, 12, 3)
displays: ' 12345.679' ( 3 spaces, 5 digits 12345, a decimal point, and three decimal digits (679). - it rounds if it has to truncate
for a Total of 12 characters, with 3 to the right of decimal point.
Just use the ROUND function:
SELECT ROUND(column, 2) FROM Cost
Or to strip the decimals and round, use CAST:
SELECT CAST(column as decimal(10, 2))
Assuming the following data:
Column1 (data type: varchar(50))
--------
11.6
-1
1,000
10"
Non-Numeric String
I have a query, which is pulling data from this column and would like to determine if the value is a number, then return it as such in my query. So I am doing the following
SELECT CASE
WHEN IsNumeric(Replace(Column1, '"', '')) = 1 THEN Replace(Column1, '"', '')
ELSE 0
END AS NumericValue
SQL is reporting back:
Conversion failed when converting the varchar value '11.6' to data type int.
Why? I have also tried to force cast this:
SELECT CASE
WHEN IsNumeric(Replace(Column1, '"', '')) = 1 THEN cast(Replace(Column1, '"', '') AS float)
ELSE 0
END AS NumericValue
And I got:
Error converting data type varchar to float.
You need to replace comma with a period:
CAST(REPLACE(column, ',', '.') AS FLOAT)
SQL Server outputs decimal separator defined with locale, but does not unterstand anything but a period in CASTs to numeric types.
First convert the string to money, then covert it to any other numeric format since money type gives a true numeric string always. You will never see an error then.
Try the following in your query, and you'll know what I am talking about. Both will return 2345.5656. The Money datatype is rounded to 4 decimal places, and hence the casting causes rounding to 4 decimal places.
SELECT CAST('2,345.56556' as money), CAST('$2,345.56556' as money)
Cast( cast('2,344' as money) as float) will work perfectly or
cast( cast('2,344' as money) as decimal(7,2)) will also work.
Even cast(CAST('$2,345.56556' as money) as int ) will work perfectly rounding it to nearest integer.
There are many issues with SQL isnumeric. For example:
select isnumeric('1e5')
This will return 1 but in many languages if you try to convert it to a number it will fail. A better approach is to create your own user defined function with the parameters you need to check for:
http://www.tek-tips.com/faqs.cfm?fid=6423
ISNUMERIC returns 1 when the input expression evaluates to a valid integer, floating point number, money or decimal type;
So the problem is it is a valid number but not a valid int.
Kyle,
I think this solves the problem. The problem lies in the fact that the ELSE clause initializes your result to be an INTEGER. By making an explicit typecast to FLOAT and adding the suggestion of Quassnoi, it seems to work.
DECLARE #MyTable TABLE (Column1 VARCHAR(50))
INSERT INTO #MyTable VALUES('11.6')
INSERT INTO #MyTable VALUES('-1')
INSERT INTO #MyTable VALUES('1,000')
INSERT INTO #MyTable VALUES('10" ')
INSERT INTO #MyTable VALUES('Non-Numeric String')
SELECT CASE WHEN ISNUMERIC(REPLACE(Column1,'"','')) = 1 THEN REPLACE(REPLACE(Column1,'"',''), ',', '.') ELSE CAST(0 AS FLOAT) END
FROM #MyTable
Regards,
Lieven
IsNumeric(' ') also returns 1, but then CAST as int blows up. Brendan above says write your own function. He is correct.
This solution does not work in all cases (specifically numbers with money and/or thousand separators). Concatenate an exponent representation to the end of the number which is represented by a string...ISNUMERIC() works fine from there. Examples below:
-- CURRENT ISNUMERIC RESULTS
SELECT ISNUMERIC('11.6'); --1
SELECT ISNUMERIC ('-1'); --1
SELECT ISNUMERIC('1,000'); --1
SELECT ISNUMERIC('10"'); --0
SELECT ISNUMERIC('$10'); --1
-- NEW ISNUMERIC RESULTS
SELECT ISNUMERIC('11.6'+'e+00'); --1
SELECT ISNUMERIC ('-1'+'e+00'); --1
SELECT ISNUMERIC('1,000'+'e+00'); --0
SELECT ISNUMERIC('10"'+'e+00'); --0
SELECT ISNUMERIC('$10'+'e+00'); --0
This, at the very least, standardizes the format for using the REPLACE() function.
I have just meet this issue.
You can try this solution if you don't mind about limitation of decimal length.
CONVERT(numeric, CONVERT(money, '.'))
NOTE:
It is supported in SQL Server 2008 or above.
Money range is : -922,337,203,685,477.5808 to 922,337,203,685,477.5807 - four decimals.
