Remove all spaces from a string in SQL Server - plaything245 - 07-31-2023 What is the best way to remove all spaces from a string in SQL Server 2008? `LTRIM(RTRIM(' a b '))` would remove all spaces at the right and left of the string, but I also need to remove the space in the middle.

For that, the following function should be used. CREATE FUNCTION RemoveAllSpaces ( @InputStr varchar(8000) ) RETURNS varchar(8000) AS BEGIN declare @ResultStr varchar(8000) set @ResultStr = @InputStr while charindex(' ', @ResultStr) > 0 set @ResultStr = replace(@InputStr, ' ', '') return @ResultStr END Example: select dbo.RemoveAllSpaces('aa aaa aa aa a') Output: aaaaaaaaaa RE: Remove all spaces from a string in SQL Server - mousebirds345199 - 07-31-2023 If it is an update on a table all you have to do is run this update multiple times until it is affecting 0 rows. update tableName set colName = REPLACE(LTRIM(RTRIM(colName)), ' ', ' ') where colName like '% %' RE: Remove all spaces from a string in SQL Server - curnin564 - 07-31-2023 Just in case you need to TRIM spaces in all columns, you could use this script to do it dynamically: --Just change table name declare @MyTable varchar(100) set @MyTable = 'MyTable' --temp table to get column names and a row id select column_name, ROW_NUMBER() OVER(ORDER BY column_name) as id into #tempcols from INFORMATION_SCHEMA.COLUMNS WHERE DATA_TYPE IN ('varchar', 'nvarchar') and TABLE_NAME = @MyTable declare @tri int select @tri = count(*) from #tempcols declare @i int select @i = 0 declare @trimmer nvarchar(max) declare @comma varchar(1) set @comma = ', ' --Build Update query select @trimmer = 'UPDATE [dbo].[' + @MyTable + '] SET ' WHILE @i <= @tri BEGIN IF (@i = @tri) BEGIN set @comma = '' END SELECT @trimmer = @trimmer + CHAR(10)+ '[' + COLUMN_NAME + '] = LTRIM(RTRIM([' + COLUMN_NAME + ']))'+@comma FROM #tempcols where id = @i select @i = @i+1 END --execute the entire query EXEC sp_executesql @trimmer drop table #tempcols RE: Remove all spaces from a string in SQL Server - loggias873058 - 07-31-2023 if you want to remove spaces,-, and another text from string then use following : suppose you have a mobile number in your Table like '718-378-4957' or ' 7183784957' and you want replace and get the mobile number then use following Text. select replace(replace(replace(replace(MobileNo,'-',''),'(',''),')',''),' ','') from EmployeeContactNumber Result :-- 7183784957 RE: Remove all spaces from a string in SQL Server - arabellavpkgosxf - 07-31-2023 To remove the spaces in a string left and right. To remove space in middle use `Replace`. You can use `RTRIM()` to remove spaces from the right and `LTRIM()` to remove spaces from the left hence left and right spaces removed as follows: SELECT * FROM table WHERE LTRIM(RTRIM(username)) = LTRIM(RTRIM("Bob alias baby")) RE: Remove all spaces from a string in SQL Server - Trix785413 - 07-31-2023 **[Reference taken from this blog:][1]** [1]: [To see links please register here] **First, Create sample table and data:** 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 **Script to 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 **Result:** Rno StringWithSpace StringWithoutSpace ----------- ----------------------------------------- --------------------------------------------- 1 I am Anvesh Patel I am Anvesh Patel 2 Database Research and Development Database Research and Development 3 Database Administrator Database Administrator 4 Learning BIGDATA and NOSQL Learning BIGDATA and NOSQL |
