You could use the CONVERT function for example:

DECLARE @Num4 AS DECIMAL(10,4)
DECLARE @Num2 AS DECIMAL(10,2)
SET @Num4 = 1234.9876
SET @Num2 = CONVERT(DECIMAL(10,2),@Num4)
SELECT @Num2
@Num2 will then equal 1234.99 -- note the rounding which has taken place.
of course this works as well

DECLARE @Num4 AS DECIMAL(10,4)
DECLARE @Num2 AS DECIMAL(10,2)
SET @Num4 = 1234.9876
SET @Num2 = @Num4
SELECT @Num2
@Num2 will then equal 1234.99 -- note the rounding

If everything seems to be going well, you have obviously overlooked something.

Much simpler than all that... check out the ROUND function or the STR function (which also right justifies if you need that for a report or file). :)

Pls try this

DECLARE @Num4 AS DECIMAL(10,4)
SET @Num4 = 1234.9876
SELECT STR(@Num4,Len(@Num4),2)

Hi,

I want to trim the value of decimal point to 2.

For example
1245.658797
123597.599945
798754.589785
787561.124657

I want this to be displayed as

1245.65
123597.59
798754.58
787561.12

If i try to use decimal(15,2) it will round off the value.

If i convert to type money then also the values get round off

The value type is real in the database

Please help...

union
select 798754.589785
union
select 787561.124657

select substring((cast(amount as char)),0,(charindex('.',(cast(amount as char)))+3)) amount from #temp
amount

123597.59

DECLARE @Num4 AS DECIMAL(10,4)
SET @Num4 = 1234.982644
SELECT LEFT(CONVERT(VARCHAR(20),@Num4),CHARINDEX('.',CONVERT(VARCHAR(20),@Num4))+2)

Hi Madhu,

When my value is like 1567987.4699987 i got the output as

1567987.47 which is actually rounding off the value

DECLARE @Num4 AS DECIMAL(10,4)
SET @Num4 = 1567987.4699987
SELECT LEFT(CONVERT(VARCHAR(20),@Num4),CHARINDEX('.',CONVERT(VARCHAR(20),@Num4))+2)

And the values specified above are just examples not real values.

Hope i am clear in my explaining the problem.

Using ROUND function...

SELECT CONVERT( NUMERIC(18,2), ROUND(1245.65879, 2, 1) )
