SQL SERVER – How to remove leading zeros after a decimal point

Recently, I came across a query in a blog, ‘How to remove leading zeros after a decimal point’. I then started developing the shortest possible solution and thought of sharing with my blog readers. Let me create a sample to demonstrate the solution.

DECLARE @tbl_sample AS TABLE
(
[ID] INT,
[Col_Varchar] VARCHAR(50)
)

INSERT INTO @tbl_sample VALUES (1,'2013.0000000001')
INSERT INTO @tbl_sample VALUES (2,'2014.0000000002')
INSERT INTO @tbl_sample VALUES (3,'2015.0000000003')
INSERT INTO @tbl_sample VALUES (4,'2016.0000000044')
INSERT INTO @tbl_sample VALUES (5,'2017.0000000555')

SELECT * FROM @tbl_sample
--OUTPUT

SOLUTION 1 :
Given below is the solution using PARSENAME & CONCAT function.

--This script is compatible with SQL Server 2012 and above.
SELECT [ID]
,CONCAT(PARSENAME([Col_Varchar],2)
,'.',CONVERT(INT,PARSENAME([Col_Varchar],1)))
AS [Col_Varchar]
FROM @tbl_sample
--OUTPUT

SOLUTION 2 :
Given below is the solution using PARSENAME & CONVERT function.

--This script is compatible with SQL Server 2005 and above.
SELECT
[ID]
,CONVERT(VARCHAR(5),PARSENAME([Col_Varchar],2))
+ '.'
+ CONVERT(VARCHAR(5),CONVERT(INT,PARSENAME([Col_Varchar],1)))
AS [Col_Varchar]
FROM @tbl_sample
--OUTPUT
