Convert Decimal to Varchar
I have a decimal column in a table defined as decimal(8,3). I would like to include this column in a Select
statement, convert it to a Varchar
and only display two decimal places. I can't seem t开发者_JAVA百科o find the right combination of options to do this because everything I try still produces three decimal places.
Here's one way:
create table #work
(
something decimal(8,3) not null
)
insert #work values ( 0 )
insert #work values ( 12345.6789 )
insert #work values ( 3.1415926 )
insert #work values ( 45 )
insert #work values ( 9876.123456 )
insert #work values ( -12.5678 )
select convert(varchar,convert(decimal(8,2),something))
from #work
if you want it right-aligned, something like this should do you:
select str(something,8,2) from #work
If you are using SQL Server 2012, 2014 or newer, use the Format Function instead:
select Format( decimalColumnName ,'FormatString','en-US' )
Review the Microsoft topic and .NET format syntax for how to define the format string.
An example for this question would be:
select Format( MyDecimalColumn ,'N','en-US' )
You might need to convert the decimal
to money
(or decimal(8,2)
) to get that exact formatting. The convert
method can take a third parameter that controls the formatting style:
convert(varchar, cast(price as money)) 12345.67
convert(varchar, cast(price as money), 0) 12345.67
convert(varchar, cast(price as money), 1) 12,345.67
I think CAST(ROUND(yourColumn,2) as varchar)
should do the job.
But why do you want to do this presentational formatting in T-SQL?
Hope this will help you
Cast(columnName as Numeric(10,2))
or
Cast(@s as decimal(10,2))
I am not getting why you want to cast to varchar?.If you cast to varchar again convert back to decimail for two
decimal points
Hope this will help .
DECLARE @emp_cond nvarchar(Max) =' ',@LOCATION_ID NUMERIC(18,0)
SET@LOCATION_ID=10110000000
IF CAST(@LOCATION_ID AS VARCHAR(18))<>' '
BEGIN
SELECT @emp_cond= @emp_cond + N' AND
CM.STATIC_EMP_INFO.EMP_ID = ' ' '+ CAST(@LOCATION_ID AS VARCHAR(18)) +' ' ' '
END
print @emp_cond
EXEC( @emp_cond)
If the type is decimal(18,0) you need to do a double convert like so:
convert(varchar, convert(decimal, [Bill to Account Number] ))
Otherwise, if you just do convert(varchar) you will get scientific notation.
