Question

I have got some improper data with some of my rows due to which I am not able to search exactly.

I have values under my category_name column like below:

category_name

interior--
exterior
interior

due to -- at the end of some category names I am not able to get exact counts of a particular category

I am using below query

select count(id) from designs where category_name='interior'

how to ignore -- while matching in where clause

Answer 1

Trim the trailing -- from values using TRIM() function like below:

SELECT count(id) FROM designs WHERE TRIM(TRAILING '--' FROM category_name)='interior'
