I am extremely new here. I know this must have been done 100s of times before as its an obvious need for end users and I have my thoughts on how to do it - but I want to ensure that I implement the most effective way.

The forms screen we use allows the user the enter search criteria for a company name.

Assume the company name is A.B. Company Inc. and this is how it is stored

Right now the code will only return this value if they filter on A. or A%B etc.

I want them to get A.B. Company Inc. even if they search on AB.
Similar for other characters like - " ' - I can get a list from the users.

I thought of creating a new column to be used for searches that would store company names after transforming them using the statement below that I picked up from another post; or this translation could be done on the fly - but I'm concerned about performance. Is this a valid concern ?

Once I have the transformed string I can do the comparison with the search criteria.

Is there any other way to do this that is efficient ?

Select translate(upper(trim(col1)),'1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ ()_+}{":?><`-=]['''';/.,','1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ')

Welcome to the forum.
You might take a look at the soundex function. An alternative might be using an Oracle Text index.
