How to remove invisible characters in t-sql?

Question

I tried

UPDATE TABLENAME SET COLUMNNAME = REPLACE(COLUMNNAME, \'\\t\', \'\')

But I don\'t know how to write the TAB in t-sql

Answer 1

One of the comments I tried above was only reading the data and not actually updating the data, I had the best success with the following

UPDATE Tbl
SET Tbl.[ColumnName] = LTRIM(RTRIM(REPLACE(REPLACE(REPLACE(Tbl.[ColumnName], CHAR(9), ' '),CHAR(13), ' '),CHAR(10), ' ')))
FROM [TableName] AS Tbl

I know this is a old question hope this helps someone
