In this post, I am sharing a solution to remove the extra spaces from a string value of SQL Server.

Before a few days ago, I was doing data migration from a CSV sources into the SQL Server Table. I checked my destination table and found lots of extra space in one of my string column.

Using below script, we can remove all unwanted spaces from a string of SQL Server.

Create the sample table:

CREATE TABLE tbl_RemoveExtraSpaces
(
	 Rno INT
	 ,Name VARCHAR(100)
)
GO

INSERT INTO tbl_RemoveExtraSpaces VALUES (1,'I    am     Anvesh   Patel')
INSERT INTO tbl_RemoveExtraSpaces VALUES (2,'Database   Research and     Development  ')
INSERT INTO tbl_RemoveExtraSpaces VALUES (3,'Database    Administrator     ')
INSERT INTO tbl_RemoveExtraSpaces VALUES (4,'Learning    BIGDATA    and       NOSQL ')
GO

SELECT string without Extra Spaces:

SELECT
	 [Rno]
	,[Name] AS StringWithSpace
	,LTRIM(RTRIM(REPLACE(REPLACE(REPLACE([Name],CHAR(32),'()'),')(',''),'()',CHAR(32)))) AS StringWithoutSpace
FROM tbl_RemoveExtraSpaces

The Result:

Script to Remove or UPDATE original string without Extra Spaces:

UPDATE tbl_RemoveExtraSpaces SET Name = LTRIM(RTRIM(REPLACE(REPLACE(REPLACE([Name],CHAR(32),'()'),')(',''),'()',CHAR(32))))
