How about this   Assuming data coming into your function as  thisData   BEGIN   DECLARE  thisText VARCHAR 255    SET  thisText   REPLACE RTRIM REPLACE  thisData   0                0     IF SUBSTRING  thisText  LEN  thisText   1            RETURN STUFF  thisText  LEN  thisText   1        RETURN  thisText END

I know this thread is very old but for those not using SQL Server 2012 or above or cannot use the FORMAT function for any reason then the following works   Also  a lot of the solutions did not work if the number was less than 1  e g  0 01230000    Please note that the following does not work with negative numbers   DECLARE  num decimal 28 14    10 012345000 SELECT PARSENAME  num 2    REPLACE RTRIM LTRIM REPLACE  num-PARSENAME  num 2   0              0     set  num   0 0123450000 SELECT PARSENAME  num 2    REPLACE RTRIM LTRIM REPLACE  num-PARSENAME  num 2   0              0      Returns 10 012345 and 0 012345 respectively

I had a similar problem  needed to trim trailing zeros from numbers like  xx0000 x00000 xxx000  I used   select LEFT code LEN code  1 - PATINDEX    1-Z    REVERSE code    from Tablename   Code is the name of the field with the number to be trimmed  Hope this helps someone else

it is possible to remove leading and trailing zeros in TSQL   Convert it to string using STR TSQL function if not string  Then  Remove both leading  amp  trailing zeros  SELECT REPLACE RTRIM LTRIM REPLACE AccNo  0              0   AccNo FROM  BankAccount  More info on forum

I was reluctant to cast to float because of the potential for more digits to be in my decimal than float can represent  FORMAT when used with a standard  net format string  g8  returned the scientific notation in cases of very small decimals  eg 1e-08  which was also unsuitable  Using a custom format string  https   docs microsoft com en-us dotnet standard base-types custom-numeric-format-strings  allowed me to achieve what I wanted   DECLARE  n DECIMAL 9 6   1 23  SELECT  n -- gt  1 230000 SELECT FORMAT  n   0          -- gt  1 23   If you want your number to have at least one trailing zero  so 2 0 does not become 2  use a format string like 0 0       The decimal point is localised  so cultures that use a comma as decimal separator will encounter a comma output where the   is  Of course  this is the discouragable practice of having the data layer doing formatting  but in my case there is no other layer  the user is literally running a stored procedure and putting the result in an email

You can use the FORMAT   function  SqlAzure and Sql Server 2012     SELECT FORMAT CAST 15 12     AS DECIMAL 9 6     g18    --  15 12  SELECT FORMAT CAST 0 0001575 AS DECIMAL 9 6     g10    --  0 000158  SELECT FORMAT CAST 2 0       AS DECIMAL 9 6     g15    --  2    Be careful when using with FLOAT  or REAL   don t use g17 or larger  or g8 or larger with REAL   because the limited precision of the machine representation causes unwanted effects   SELECT FORMAT CAST 15 12 AS FLOAT    g17           --  15 119999999999999  SELECT FORMAT CAST 0 9 AS REAL    g8               --  0 89999998  SELECT FORMAT CAST 0 9 AS REAL    g7               --  0 9    Furthermore  note that  according to the documentation       FORMAT relies on the presence of the  NET Framework Common Language   Runtime  CLR   This function will not be remoted since it depends on   the presence of the CLR  Remoting a function that requires the CLR   would cause an error on the remote server    Works in SqlAzure  too

Another option     I don t know how efficient this is but it seems to work and does not go via float   select replace rtrim replace         replace rtrim replace cast  value as varchar 40     0                0                                    The middle line strips off trailing spaces  the outer two remove the point if there are no decimal digits

The best way is NOT converting to FLOAT or MONEY before converting because of chance of loss of precision  So the secure ways can be something like this     CREATE FUNCTION  dbo   fn ConvertToString         value sql variant   RETURNS varchar max  AS BEGIN     declare  x varchar max      set  x  reverse replace ltrim reverse replace convert varchar max     value   0             0        --remove  unneeded  dot  if any     set  x   Replace RTRIM Replace  x                         return  x END   where  value can be any decimal x y

A decimal 9 6  stores 6 digits on the right side of the comma   Whether to display trailing zeroes or not is a formatting decision  usually implemented on the client side   But since SSMS formats float without trailing zeros  you can remove trailing zeroes by casting the decimal to a  float   select      cast 123 4567 as DECIMAL 9 6       cast cast 123 4567 as DECIMAL 9 6   as float    prints   123 456700  123 4567    My decimal separator is a comma  yet SSMS formats decimal with a dot   Apparently a known issue

A DECIMAL 9 6  column will convert to float without loss of precision  so CAST     AS float  will do the trick      HLGEM  saying that float is a poor choice for storing numbers and  Never use float  is not correct - you just have to know your numbers  e g  temperature measurements would go nicely as floats    abatishchev and  japongskie  prefixes in front of SQL stored procs and functions are still a good idea  if not required  the links you mentioned only instructs not to use the  sp   prefix for stored procedures which you shouldn t use  other prefixes are fine e g   usp   or  spBob    Reference   All integers with 6 or fewer significant decimal digits can be converted to an IEEE 754 floating-point value without loss of precision   https   en wikipedia org wiki Single-precision floating-point format

I had a similar issue  but was also required to remove the decimal point where no decimal was present  here was my solution which splits the decimal into its components  and bases the number of characters it takes from the decimal point string on the length of the fraction component  without using CASE   To make matters even more interesting  my number was stored as a float without its decimals   DECLARE  MyNum FLOAT SET  MyNum   700000 SELECT CAST PARSENAME CONVERT NUMERIC 15 2   MyNum 10000  2  AS VARCHAR 10      SUBSTRING     1 LEN REPLACE RTRIM REPLACE CAST PARSENAME CONVERT NUMERIC 15 2   MyNum 10000  1  AS VARCHAR 2    0             0        REPLACE RTRIM REPLACE CAST PARSENAME CONVERT NUMERIC 15 2   MyNum 10000  1  AS VARCHAR 2    0             0      The result is painful  I know  but I got there  with much help from the answers above

I needed to remove trailing zeros on my decimals so I could output a string of a certain length with only leading zeros   e g  I needed to output 14 characters so that 142 023400 would become 000000142 0234    I used parsename  reverse and cast as int to remove the trailing zeros   SELECT     PARSENAME 2 5500 2                  REVERSE CAST REVERSE PARSENAME 2 5500 1   as int      To then get my leading zeros I could replicate the correct number of zeros based on the length of the above and concatenate this to the front of the above   I hope this helps somebody
