regex - Oracle declare select into update statement does not work -

-

i had issue due database charset special characters weird codes assigned them, getting select ascii(substr(declinereasondesc, 30,1)) declinereason t declinereasonid = 7; got code (49827) £ in db charset. tried update records in database.

problem getting data not saved db or selecting into value varchar2(6); somehow changes , not match regexp_replace any-more.

it did error when tried using varchar2(1) should value, hint.

declare c varchar2(6); begin  select ascii(substr(declinereasondesc, 30,1)) c declinereason t declinereasonid = 7; begin    update declinereason set declinereasondesc = regexp_replace(declinereasondesc, '(.+)('||c||')(\d+)', '\1\3 (gbp)');   commit;   end; end; / commit;

update: tried declare c number; no errors didn't update values ether

this 1 caused me being stupid - forgot wrap c in chr(c).

declare c number; begin  select ascii(substr(declinereasondesc, 30,1)) c declinereason t declinereasonid = 7; begin    update declinereason set declinereasondesc = regexp_replace(declinereasondesc, '(.+)('||chr(c)||')(\d+)', '\1\3 (gbp)');   commit;   end; end; /   commit;
