Prxmatch

[SASPhile]

I would like to use prxmatch on two columns from two tables in a proc Sql. But it doesn't seem to work.

Here is the logic I tried.

Proc sql;

Where prxmatch(a.text,b.text)>0

Quit;

Please look at the documentation. The first parameter must be a regular expression. I have to learn regular expressions before you can use that function.

[SASPhile]

I know, but something in that likes. A fuzzy match is required.

[ChrisNZ]

What are the match criteria? Have you looked at the spelling distance functions?

Are you trying to do something like the following:

data have1;
  input text $;
  cards;
abc
bcd
bca
fgf
;
data have2;
  input text $;
  cards;
bcd
fgf
;

proc sql;
  select text
    into :from1
      separated by '|'
        from have2
  ;

  create table want as
    select text
      from have1
        where prxmatch('m/&from1/oi',text)>0
  ;
quit;

Yes Art, Something in that likes!

[SASPhile]

there are special characters to be compressed from both have1 and have2 as they are not consisternt for matching

[art297]

Can you provide examples of both datasets and what you want to match from them?

[SASPhile]

the data from two sources is like this,

Have1

Finance Exchequer Credit Bankrupt and Mortgage

Have2
Finance,exchequer,Credit Bankrupt and Mortgage

Trying to match with whole pattern or part of it.

[ChrisNZ]

Why not remove the unwanted characters with function compress, and then use spelling distance? 

[ChrisNZ]

Your example matches with 

upcase(compress(TEXT1,' ,')) =  upcase(compress(TEXT2,' ,'))

[SASPhile]

Not always do I get the same pattern. Thats why I'm relying on fuzzy match

[art297]

Your example doesn't include any fuzzy or fuzzy-like instances. Can you provide an example that does. And, your example appears to have one record with just one variable (containing multiple words) in each file. Is that what you actually have?

[SASPhile]

Yes Art!

[SASPhile]

even if partially matches that is fine too.
