RE: Converting names & street names

Huh?

I fail to see how EBCDIC is any more consistent than ASCII.

In ASCII, lowercase comes after uppercase.

In EBCIDIC, assuming CCSID 37 then by default lowercase comes before
uppercase.

CREATE TABLE QTEMP/TESTCW (FLD1 CHAR (10 ) NOT NULL WITH DEFAULT)
INSERT INTO QTEMP/TESTCW VALUES('Charles')
INSERT INTO QTEMP/TESTCW VALUES('CHARLES')
INSERT INTO QTEMP/TESTCW VALUES('APPLE') 
INSERT INTO QTEMP/TESTCW VALUES('apple')
INSERT INTO QTEMP/TESTCW VALUES('charles')

select * from testcw order by fld1 
apple   
charles 
APPLE   
Charles 
CHARLES 

Now if you change the sort sequence to *LANGIDSHR then you get:
APPLE   
apple   
Charles 
CHARLES 
charles 


HTH,

Quoting Jeff Crosby <jlcrosby@xxxxxxxxxxxxxxxx>:

The only way to get this right is not to lose the mixed-case
form in the first place.  If it's not feasible just to store
the name in mixed-case and upper-case it for comparisons

To me, the only reason this data is stored in the database 

in uppercase is

inertia.  Years and years ago printers could only print uppercase.

For all of you that are smarter than me:

Suppose I decide I'm going to just store the data in the database in
mixed-case form.  What are the ramifications?  Will sorts 

and OPNQRYF and

SQL still _sequence_ them in true alphabetical order?  I 

understand that

comparisons for include/equal/etc need to be altered as 

"Joe" and "JOE" will

not compare equal.  What other kinds of thing are there?

As long as Midrange-L has been here and as often as other 

topics have

repeated themselves ad nauseum, I'm rather amazed we 

haven't hashed this out

before.  'Course I lose brain cells on a monthly basis . . .

One interesting aspect of AS/400 is that it uses EBCDIC.  
Sorts are consistent
with that character set.  I worked on another computer, years 
ago, that was
ASCII.  A file of names was sorted and printed on an upper case only 
printer. Nobody was happy with the results.  Nobody knew to 
look at the 
data to see that
it had been entered as both all upper case as well as mixed 
case.  A small
program change worked around that sort issue.
