Question

I have a column that contains strings as:

aaa_1
aaa_11

I need to query strings that ends with _1. I tried the following:
select col from table where col like %_1;
But the query gives me the strings that ends with _1 and _11. How can I correct this ?

Answer 1

Try this:

select col from table where col like '%\_1'

character _ is a jolly, like %, but it matches only a single character, so you have to escape it with \
