How to search for a new line character in sql

Question

hi..i am using oracle 10g.
basically i am looking for usage of columns.I want to see which all columns are used in
joins.
this is the quey i have written.
but
if there a new line between WHERE ,AND those scenarios are ignored.how to take care of these new line characters?
SELECT DISTINCT s.TYPE, s.NAME, s.owner, table_name, column_name --,line,text
FROM all_source s, cols c, all_dependencies d
WHERE s.NAME = d.NAME
AND d.referenced_name = c.table_name
AND c.table_name = 'WSF_EDUCATION_ORGUNIT'
AND column_name ='ORGUNIT_TYPECODE_OID'
AND d.TYPE = s.TYPE
AND d.TYPE <> 'PACKAGE'
AND d.owner = s.owner ---FOR OVERLOADED OBJECTS
AND ( (UPPER (text) LIKE
'%' || 'AND' || '%' || column_name || ' ' || '=%'
OR (UPPER (text) LIKE
'%' || 'AND' || '%=' || ' ' || '%' || column_name
|| '%'
UNION ---if there is where

Hi,
Not sure if I get it, but you can look for characters using the ascii and chr functions.
You can change them using replace:
A new line:
SQL> select ascii('
  2  ') from dual;
ASCII('')
        10(Just press enter between the quotes)
Example how to replace it with a space:
SQL> with t as ( -- generating test string:
  2  select 'this string has
  3  a new line' str from dual
  4  )
  5  --
  6  -- actual query:
  7  --
  8  select str
  9  ,      replace(str, chr(10), chr(32))
10  from   t;
STR                        REPLACE(STR,CHR(10),CHR(32
this string has            this string has a new line
a new lineIf that isn't clear of when I'm missing the point then please post some narrowes down examples of what you get now and your desired output. Remember to put the tag around any code example you're posting.
