RE: Using SQL to select records containing an embedded blank



fixed

I don't know if it performs any better, worse but I think it would be more accurate for finding imbedded blanks:

select *
from myFile
where trim(myField) like '% %'

Had a typo in there, so correction:

SELECT * FROM myFile
WHERE POSITION(' ' IN myField) > 0 AND
POSITION(' ' IN myField) < LENGTH(RTRIM(myField))

If I'm understanding you correctly, something like this ought to work:

SELECT * FROM myFile
WHERE POSITION(' ' IN myField) > 0 and
POSITION(' ' IN myField) < LENGTH(RTRIM(F1))

There are probably number of other ways to accomplish the same.

Subject: Using SQL to select records containing an embedded blank

Is it possible to use interactive sql on the i to find records where a particular field contains embedded blanks?

I mean one or more non-blanks followed by one or more blanks followed by one or more non-blanks.

I can do it with an RPG program, of course, but am trying to learn to use sql where appropriate.

Any suggestions?

Thanks,
Lance
