Regarding characters validation

Question

Dear All i ma using 10G.
I am writing this query for character validation ..
Select TRANSLATE( lstring, '$ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789/-?:().,''+{}', '$') FROM dual;
It is working fine ..
Now i created a table and save (ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789/-?:().,''+{}') this in that table .
But in my plsql block i am trying to fetch INTO a variable but it is not working properly ..
I mean it is coming extra $$$ ....
Begin
Select SWIFT_FOR_ACCOUNT into lcode
from MU_PAY_PARAM_VALIDATOR
Where rownum = 1;
Select TRANSLATE(lac_no, lcode,'$') into ochar
FROM dual;
If ochar is null then
Null ;
Else
Dbms_output.put_line('There are extra characters exit in the account no , like :-'||ochar );
Insert into MU_SIMULATOR_output_ERR (load_no,ERR_CODE,ERR_DESC) values (1111,'0021','Invalid account number');
Commit;
End if;
Exception
When NO_Data_Found Then
null;
End;
So how to do this ?

Then it is working fine . Means if the string is comes within the characters then it should return null else it should return the character which is not in the list ..
for example : I am passing SAN123/-? then it should return Null , that means it is correct .Remember how TRANSLATE (s, f, t) works: it returns a copy of s with the nth character of f replaced by the nth character of t. If LENGTH (T) < n, then it replaces the nth character of f with NULL, or removes it.
Let's format your expression to make this more clear:
TRANSLATE ( 'SAND123'
          , '$ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789/-?:().,''+{}'
          , '$'
          )The expression above is "trtanslating" '$' to '$, and translating all the other characters of f ('A', 'B', 'C', ..., '}') to nothing.
Now i am passing this :- SAN123/-?>< Then it should return >< . It is wrong data .
But same thing i want to in PLSQL ..Then do the same thing in PL/SQL; use the same f argument that you are using outside of PL/SQL.
For that i have created a table tab1 with this column COL1 .
And in this column i have stored this value ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789/-?:().,''+{}
So what you're doing is equivalent to
TRANSLATE ( 'SAN123/-?>'    -- There's another character at the end of this string, but it causes this site to display incorrectly
          , 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789/-?:().,''+{}'
          , '$'
          )This is translating all the 'A's to '$'s, and all the other characters in t ('B', 'C', 'D', ..., '}') to nothing.
Add a '$' to the beginning of lcode.
