Subquery in select statement syntax error - sql

Question

I am trying to run the below query and i keep getting the error:**ORA-01756: quoted string not properly terminated**
SELECT
InnerTable."Cycle ID",
(
SELECT REPLACE(SYS_CONNECT_BY_PATH(CF_ITEM_NAME,'//'),'//','/')
AS "Path1"
FROM CYCL_FOLD
START WITH CF_FATHER_ID = InnerTable."Cycle ID"
CONNECT BY PRIOR CF_ITEM_ID = CF_FATHER_ID
) as "path1",
InnerTable."CSR/RCQ Name",
TEST.TS_DESCRIPTION as "Test Case Description",
FROM
(-- few conditions here
) InnerTable INNER JOIN TEST ON InnerTable."Test Case ID" = TEST.TS_TEST_ID
Can any body tell me what is wrong with the syntax..Thanks so much..

Answer 1

This error means you have an odd number of single quotes.
The snippet you posted only contains balanced pairs of quotes - in the REPLACE(SYS_CONNECT_BY_PATH(CF_ITEM_NAME() chain. So the problem must lie in the excised part of your query:
-- few conditions here
Does the redaction include any string literals? If so check them.
This error is easy to spot with an IDE which supports SQL syntax highlighting.
" i don't find any error with the single or double quotes"
Me neither. Hmmm.
There is the possibility that the / is escaping the quote somehow. That will depend on you client settings. In SQL*Plus ESCAPE is off by default and besides the default escape character is \. So your statement would work on my set-up ...
SQL> sho escape
escape OFFSQL> select '//' from dual
2 /
'/
--
//
SQL> c.//./
1* select '/' from dual
SQL> r
1* select '/' from dual
'
-
/
SQL> set escape on
SQL> r
1* select '/' from dual
'
-
/
SQL>
... but check your client settings anyway.
