Search for White space within strings

Question

create table emp_dtl
(empname varchar2(23));
Insert into emp_dtl values ('WAYNE');
Insert into emp_dtl values ('JOSEPH KRUPP');     --------- has white space
Insert into emp_dtl values ('YING ZONG LEE');    --------- has white space
Insert into emp_dtl values ('COHEN');
Insert into emp_dtl values ('MARIE');How can i search for empnames which has White space in it? From other OTN threads, I gathered that this has something to do with
chr(32)But i don't know how to put this in LIKE operator.

Answer 1

Hi,
SELECT  *
FROM    emp_dtl
WHERE   REGEXP_LIKE (empname, '\s')
;will look for any kind of whitespace (including spaces, which are CHR (32)).
It may be more efficient to specifically list all the different whitespace characters, and see if the string changes when you remove all of them:
SELECT     *
FROM     emp_dtl
WHERE     empname != TRANSLATE ( empname
                       , 'x ' || CHR (9)     -- CHR (9)  = <tab>
                                      || CHR (10)     -- CHR (10) = <newline>
                             || CHR (13)     -- CHR (13) = <return>
                       , 'x'
