Hi expert,
below is my query
SELECT *
  FROM (SELECT REGEXP_REPLACE(
                   REGEXP_SUBSTR(
                       :JSONdata,
                       '"[0-9]+".+?}}',
                       1,
                       LEVEL
                   ),
                   '^[{"]+|[},]+&'
               )
                   AS rec
          FROM DUAL
        CONNECT BY LEVEL <= 11)
 WHERE rec IS NOT NULL;

Open in new window


jsondata is given here :
 {"1":{"YBG":1,"BNT":"vc{//}}vm"},"2":{"YBG":1,"BNT":"vc}{}}vm"},"3":{"YBG":1,"BNT":"vc{}}vm"}}

Open in new window


Note:Note:inside 'vcvm'  IF i give any special character . it will take a whole string it should not trim any characters
result:
1":{"YBG":1,"BNT":"vc{//}vm"},"2":{"YBG":1,"BNT":"vc}{
3":{"YBG":1,"BNT":"vc{

expected result:
 1":{"YBG":1,"BNT":"vc}{//}vm
 2":{"YBG":1,"BNT":"vc}{}}vm
 3":{"YBG":1,"BNT":"vc}{}}vm

Regards
Thomos

I get the expected results.

Below is my test case (use sqlplus against an 11.2.0.2 database) and my results.

My guess is whatever you are using to execute the SQL is interpreting the double slashes in some way.



SQL> var JSONdata varchar2(100)
SQL>
SQL> exec :JSONdata := '{"1":{"YBG":1,"BNT":"vc{//}}vm"},"2":{"YBG":1,"BNT":"vc}{}}vm"},"3":{"YBG":1,"BNT":"vc{}}vm"}}'

PL/SQL procedure successfully completed.

SQL> SELECT *
  2    FROM (SELECT REGEXP_REPLACE(
  3                     REGEXP_SUBSTR(
  4                         :JSONdata,
  5                         '"[0-9]+".+?}}',
  6                         1,
  7                         LEVEL
  8                     ),
  9                     '^[{"]+|[},]+&'
 10                 )
 11                     AS rec
 12            FROM DUAL
 13          CONNECT BY LEVEL <= 11)
 14   WHERE rec IS NOT NULL;

1":{"YBG":1,"BNT":"vc{//}}
2":{"YBG":1,"BNT":"vc}{}}
3":{"YBG":1,"BNT":"vc{}}

hello slight wv

see my  expeceted output:
1":{"YBG":1,"BNT":"vc}{//}vm
 2":{"YBG":1,"BNT":"vc}{}}vm
 3":{"YBG":1,"BNT":"vc}{}}vm

your output:
1":{"YBG":1,"BNT":"vc{//}}
2":{"YBG":1,"BNT":"vc}{}}
3":{"YBG":1,"BNT":"vc{}}

After  that  all charecters 'vm' characters are missing.

You had a typo from the solution in your previous question.

Based on the new requirement try this:
var JSONdata varchar2(100)

exec :JSONdata := '{"1":{"YBG":1,"BNT":"vc{//}}vm"},"2":{"YBG":1,"BNT":"vc}{}}vm"},"3":{"YBG":1,"BNT":"vc{}}vm"}}'


SELECT *
  FROM (SELECT
  	REGEXP_REPLACE(
                   REGEXP_SUBSTR(
                       :JSONdata,
                       '"[0-9]+".+?"}',
                       1,
                       LEVEL
                   )
                   ,
                   '^[{"]+|["}]+$'
               )
                   AS rec
          FROM DUAL
        CONNECT BY LEVEL <= 11)
 WHERE rec IS NOT NULL;
