I have the following invisible character in my dataset
Which I believe is this character
http://www.fileformat.info/info/unicode/char/0008/index.htm
How do I remove this? I've tried
UPDATE events SET `value` = TRIM(REPLACE(`value`, CONVERT(char(8) USING hp8), ''))
MySQL escape sequence for literal backspace character is \\b
.
See "Special Character Escape Sequences" here:
http://dev.mysql.com/doc/refman/5.7/en/string-literals.html
If I needed to remove that character from a string column, I'd use an expression like this:
REPLACE(foo,'\b','')
I'd test that expression in a SELECT statement before I tried an UPDATE, eg
SELECT t.foo
, REPLACE(t.foo,'\b','')` AS new_foo
FROM mytable t
WHERE t.foo LIKE '%\b%'
