Hello All,
I am tying to migrate data from some existing DB tables to another.I came across a  strange problem in converting a RAW datatype to VARCHAR2/NUMBER.

The source table has got one column(friend_group_ids) which is of RAW(500) datatype.I found in the PL/SQL script which populates the values to the table as follows (snipped unnecessary code):
 friend_group_id number :=101000000
 group_id varchar2(10);

 group_id := NumbertoHex(friend_group_id, 16,8);

NumbertoHex is a user defined function which converts this number to Hex(101000000 => 06052340).

The INSERT statement in PL/SQL procedure is as follows:
insert into tst_friends (NUMERIC_ID , FRIEND_GID ,  NUM_OF_GROUPS, FRIEND_GROUP_IDS)
      values ( NUMERIC_ID , friend_gid,1 , group_id );

I understand this is possible,since it works.But is it correct to store varchar2 in RAW datatype.

Since I don't have the access to the actual tables, I created the table with the same schema structure but to insert the sample values I used the following INSERT statement:
insert into ODG_FRIENDS
(NUMERIC_ID, FRIEND_GID, NUM_OF_GROUPS, FRIEND_GROUP_IDS)
VALUES
(12003,'user05@foo.com',1,'06052340');

The INSERT was successful.

But I wanted to convert the friend_group_ids to "VARCHAR2"  back to do some manipulation  before I store the data in another table.I tried UTL_RAW.CAST_TO_VARCHAR2(friend_group_ids) but it produced some ascii characters.

May I know how can I get the column data value as "06052340"?

Thanks
Karthik

hi,

declare
 v varchar2(100);
begin
 select rawtohex(col1) into v from temp;
 dbms_output.put_line(v);
end;
/

using this way, you can get the raw data in the form of hex value represented in varchar2 datatype.

when you use the UTL_RAW package, it does an ascii character mapping. that is why you got the junk characters

Have a hice day
