Обсуждение: Replace function BUG

In postgreSQL 7.3.2 when I execute the following query

select replace('test %400% result', 'result', 'ok');



it returns "test % ok"



And If I Execute:

select replace('test %%400%% result', 'result', 'ok');

it returns the correct result: "test %400% ok"



If this is a known BUG please tell me because I need to fix this.



Thanks

I think this was fixed in the 7.4 branch.

It was fixed in 7.3 branch as well:

2003-04-23 14:19  tgl

    * src/backend/utils/adt/varlena.c (REL7_3_STABLE): Fix misbehavior
    of replace() on strings containing '%'.  Will patch separately but
    equivalently in HEAD.

            regards, tom lane

7.4.2 gives it like this:

testbed=# select replace('test %%400%% result',
'result', 'ok');
     replace
-----------------
 test %%400%% ok
(1 row)

testbed =# select replace('test %400% result',
'result', 'ok');
    replace
---------------
 test %400% ok
(1 row)
