Question

I remember seeing someone use a function in Oracle where they could specify a percentage of text matching. For example:

0123456789 would match this: 1123456789 by 90% or something (I’m no mathematician, but hopefully you get the idea…)

I can’t quite think of the right keywords to search for to find the function I’m looking for. Can anyone help me out with this? Thanks.

It would probably look something like this:

select *
from something s
where matches(s.textcolumn, 'Matching Text') > .9

Answer 1

The package you are looking for is utl_match.

It contains functions for comaparing strings by edit distance and similarity.
