SQL - How do I get only the numbers after the decimal?

Question

How do I get only the numbers after the decimal?

Example: 2.938 = 938

Answer 1

The usual hack (which varies a bit in syntax) is

x - floor(x)

That's the fractional part. To make into an integer, scale it.

(x - floor(x)) * 1000

Answer 2

Make it very simple by query:

select substr('123.123',instr('123.123','.')+1, length('123.123')) from dual;

Put your number or column name instead 123.122

Answer 3

If you want to select only decimal numbers use this WHERE clause:

    (CAST(RIGHT(Myfield, LEN( Myfield)-CHARINDEX('.',Myfield)+1 ) AS FLOAT)) <> 0

If you want a clear list you can sort by decimal/integer:

    CASE WHEN 0 = CAST(RIGHT(Myfield, LEN( Myfield)-CHARINDEX('.',Myfield)+1 ) AS FLOAT) THEN 'Integer' ELSE 'Decimal' END AS Type

Answer 4

You can use FLOOR:

select x, ABS(x) - FLOOR(ABS(x))
from (
    select 2.938 as x
) a

Output:

x                                       
-------- ----------
2.938    0.938

Or you can use SUBSTRING:

select x, SUBSTRING(cast(x as varchar(max)), charindex(cast(x as varchar(max)), '.') + 3, len(cast(x as varchar(max))))
from (
    select 2.938 as x
) a

Answer 5

one way, works also for negative values

declare @1 decimal(4,3)
select @1 = 2.938

select PARSENAME(@1,1)

Answer 6

try this:

SELECT (num % 1)
