How can I use like ' ' to choose sth start with letter but followed only numeric numbers

septemberbulb — Tue, 17 Jan 2017 16:23:04 GMT

Hello,

For a variable called Marketing_Source_Code, I want to exclude the code starting with a “P” followed by 3 digits. for example 'P121'.

I've used where Marketing_Source_Code like 'P___', but it will also delete the ones start with "P' followered by characters, for example 'PERN'.

How can I only exclude the code starting with a “P” followed by 3 digits. I may need this in urgent but dont know how to search the result.

Thanks a lot.

You can do:

if length(strip(translate(var,' ','0123456789')))=1 then put 'OK'; else put 'NOT-OK';

Hello,

ANYDIGIT might help in that case.

data b ;
set a ;
where not(a like "P%" and anydigit(a) in (2,3,4)) ;
run ;

---Update---

Well, it is more tricky than I thought...

This one should work better:

data b ;
set a ;
where not(a like "P%" and anyalpha(substr(a,2,3))=0) ;
run ;

Some relevant questions:

1. Is your variable always 4 characters long?

2. If it is only 3 characters long in some cases, how should P12 be handled?

proc sql;

delete from plc_cust_income

where (MKT_SOURCE_CODE='RCS1' OR MKT_SOURCE_CODE='BFCE' OR MKT_SOURCE_CODE='EXEM' OR (MKT_SOURCE_CODE like "P%" and anyalpha(substr(MKT_SOURCE_CODE,2,3))=0)) 😉

Is that right?

thanks

OK. It's possible that some of the earlier solutions posted by others are working. Here's a DATA step statement that I know works when you always have four characters:

if Marketing_Source_Code =: 'P' and input(substr(Marketing_Source_Code, 2), ??3.) > . then delete;
