Hi,

I have amount value for which I have to do the following

1. Should be fitted in 10 chars
2. left pad with zeros the remaining chars apart from the value
3. Should be showing - ve sign for the amount field if present
4. if the amount is -ve '-' symbol should be displayed in front of the value.

For eg: there is a value -45.10

it should be printed as -000045.10

Below is what I have done so far.

Any help is very appreciated

SQL

select REPLACE(CONVERT(CHAR(10),tbl.Amount),' ','0')
from table tbl

"0000-40.00" is the result I am getting with the above query.

If a -ve sign is present as above in the string it should be in the first place "-000040.00"

Try this:

SQL

DECLARE @number decimal(10,2)
SET @number = -45.10
SELECT
   CASE
      WHEN @number < 0 THEN
         '-' + RIGHT('000000000' + CONVERT(VARCHAR(9), ABS(@number)), 9)
      ELSE
         RIGHT('0000000000' + CONVERT(VARCHAR(10), @number), 10)
   END

Solution 1

Try:

SQL

SELECT CASE WHEN MyColumn < 0 THEN '-' + RIGHT('00000000' + CONVERT(NVARCHAR,-MyColumn), 9) ELSE RIGHT('000000000' + CONVERT(NVARCHAR,MyColumn), 10) END As NumericValue FROM MyTable

This should work:

SQL

SELECT STUFF(CAST(Val AS VARCHAR(10)),CASE WHEN Val<0 THEN 2 ELSE 1 END,0,REPLICATE('0',10-LEN(CAST(Val AS VARCHAR(10)))))

but it performs the CAST twice, which I don't like. I would use a Common Table Expression to eliminate the duplicated effort.

SQL

WITH cte0 AS
(
    SELECT -45.10 Val
)
, cte1 AS
(
    SELECT Val , CAST(Val AS VARCHAR(10)) ValStr FROM cte0
)
SELECT STUFF(ValStr,CASE WHEN Val<0 THEN 2 ELSE 1 END,0,REPLICATE('0',10-LEN(ValStr)))
FROM cte1

Or, if you can upgrade, you can use the FORMAT function:

SQL

SELECT FORMAT(-45.10,'000000.00')
