Im trying to do a select on the company name(cpnm) field of our company table but only giving me the first 6 characters, replacing all spaces plus making it lowercase.
SELECT *,
SUBSTRING(LOWER(cpnm), -LENGTH(cpnm), 6) as test
FROM company
LIMIT 100
The above works fine but as soon as I try to add the replace spaces (shown below), it doesnt give back results.
SELECT *,
SUBSTRING(LOWER(REPLACE(cpnm, ' ', '')), -LENGTH(cpnm), 6) as test
FROM company
LIMIT 100
Any ideas?
I guess by replacing the spaces you change the length of the string, therefore substr()
doesn't work like you expect it.
Try SELECT *, SUBSTRING(LOWER(REPLACE(cpnm, ' ', '')), -LENGTH(REPLACE(cpnm, ' ', '')), 6) as test
instead!
