How to retrieve the column with mandatory decimal point in Sql 2008? - sql

I am retrieving a numeric value from one of the column in Sql. However I have to retrieve it by three decimal point (eg below).
Though if the value in the table is in the decimal point, then its giving the result as expected. But in case the value is not in decimal format and only an integer it must display .000
Below is the example.
Value in table= 2
Retrieval Value = 2
Required Value = 2.000


As per your requirement convert your incoming value in Decimal(18,3). like given below,
select convert(decimal(18,3),2)


To really show a value in a particular format, you can convert the value to a string. One method uses the str() function:
str(x, 18, 3)
Note that you can also cast() the decimal:
select cast(cast(x as decimal(18, 3)) as varchar(19))

How to format a SSRS field with 2-digits of procession when the data is a mix of formats

I have data from a Stored Procedure that looks like this and needs to display on my report with 2-digits of precision. The data is all NVARCHAR but there is a mix of rows that looks numeric or says 'Max'.
How do I display only 2 digits of precision? I tried the following which works great on the numeric looking data but errors on 'Max'.
=FormatNumber(Fields!TBS.Value, 2)

Use an IIF to determine if the value is a number and IIF so, format it.
=IIF(ISNUMERIC(Fields!TBS.Value), FormatNumber(Fields!TBS.Value, 2), Fields!TBS.Value)
IsNumeric:
Returns a Boolean value indicating whether an expression can be
evaluated as a number.

set fixed number of zeroes before and after decimal in sybase

I need to set the value of a field in table depending on conditions whose value I am getting from another table. The data type of this field is float. The requirement is I need to have 2 digits before decimal and 4 after. So if a value is 9.45, I need to set it 09.4500. I am wondering what might be the best way to do this. Should I convert the value into varchar and then do substring? Or can this be done setting precision?
Thanks!

First, don't store such a value as a float. You have described the decimal(6, 4)/numeric(6, 4) data type very closely.
If you have this as a float or decimal, you can use str() and then pad to the right:
select right('000000' + str(9.45, 6, 4), 7)

Round a value to two decimal places in SQL

I am trying to round a value in SQL, here is the code that I have:
select round(600.000,2)
How do I get the value 600.00?

Instead of round() convert to a decimal:
select cast(600.000 + 0.5 as decimal(10, 2) )
round() changes the value but it might not change the type of the result. Hence, you might still see extra decimal points (depending on the database and the application). Converting to a decimal with two digits of precision converts both the value and the type.

format decimals and comma to numbers retrieved

I have a column in my table which showing an amount. The amount is varying from one column to another and they are more than 15 digits.
What is the best way to format the number to show commas and decimal points?
My query is
select amount from ccamounts
How can I format the number
205511892078
to show as
205,511,892,078
and if there is a radix point it will also appear.

I believe you can use TO_CHAR to do this, the issue is that this is just a formatting function within SQL. It requires that your number is always going to be in the same format.
taking the example above you could do
TO_CHAR('205511892078', '999,999,999,999')
and this would format the number as you have specified, with a decimal place this can be done aswell but the decimal needs to be specified:
TO_CHAR('20551189207842', '999,999,999,999.99')
which would give you 205,511,892,078.42
I think if the field length is going to vary sql will just ignore anything that doesn't fit into the format string (It's a mask). Perhaps you want to consider formatting the number in this case on whichever front end you may be using?

I would format the number in the UI / Reporting tool / Presentation layer not Oracle
but if you MUST format it in oracle try:
SELECT
CASE WHEN INSTR( TO_CHAR(205511892078),'.')>0 THEN
TO_CHAR(205511892078 ,'999,999,999,999.99')
ELSE
TO_CHAR(205511892078 ,'999,999,999,999')
END
FROM DUAL
this will return the number as a string.

declare #d3 decimal (10, 2)
set #d3 = 12309809.5494
SELECT convert(varchar(15),cast(CAST(ROUND(#d3,2,1) AS DECIMAL (30,2)) as money),1) as Value
SELECT CAST(ROUND(convert(varchar(30), cast(#d3 as money),2),2,1) AS DECIMAL (30,2)) as Value
Output:
12,309,809.55
12309809.55

Select all rows where a varchar column converts to a decimal

I have a varchar column that has generally has a decimal value, but some times there is some garbage text characters in that field.
Is it possible to filter in the WHERE clause for rows that sucessfully convert to a decimal value?
I am using sql-server 2005

One way is the ISNUMERIC function:
select * from YourTable where ISNUMERIC(col1) = 1
There's one gotcha: isnumeric returns 1 whenever a string can be converted to any numeric type, including money. For example, say you have rows using varying decimal separators, like 7.9 and 7,9. Both will convert to money, and isnumeric returns 1 for both of them. But only one converts to decimal, depending on the SQL Server language settings.
