is it possible that there are spaces on the end?   what type is
stck_sym?  if it's varchar or text the padding won't be removed
automatically.

example:

basement=# create table test (t varchar(6));
CREATE TABLE
basement=# INSERT into test values( 'ZRAN  ');
INSERT 92249850 1
basement=# select * from test where t = 'ZRAN';
  t
---
(0 rows)

basement=#
