<br>
I got the message "SQL state: 22P02" <br>
<br>
<br>
<br>
<b>to produce:</b><br>
<br>
create table test (num varchar(20));<br>
<br>
insert into test (num) values (null);<br>
select * from test where cast(num as int8) = 0; --ok, no error<br>
insert into test (num) values ('123123');<br>
select * from test where cast(num as int8) = 123123; --ok, no error<br>
<br>
insert into test (num) values (' ');<br>
select * from test where cast(num as int8) = 123123; -- error<br>
select * from test where case when trim(num) <> '' then cast(num
as int8) = 123123 else false end; -- ok, changed query and no error<br>
<br>
insert into test (num) values ('a');<br>
select * from test where cast(num as int8) = 123123; -- error<br>
select * from test where case when trim(num) <> '' then cast(num
as int8) = 123123 else false end; -- error<br>
<br>
I need get all tuples was the table have converting the characters to
number. If one conversion fail there not displayed. <br>

<b>Ex:</b><br>
num return<br>
---- ------<br>
0 0<br>
null false<br>
12 12<br>
a false<br>
12ab false<br>
