<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;&nbsp;&nbsp; --ok, no error<br>
insert into test (num) values ('123123');<br>
select * from test where cast(num as int8) = 123123;&nbsp;&nbsp; --ok, no error<br>
<br>
insert into test (num) values ('&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ');<br>
select * from test where cast(num as int8) = 123123;&nbsp; -- error<br>
select * from test where case when trim(num) &lt;&gt; '' 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;&nbsp; -- error<br>
select * from test where case when trim(num) &lt;&gt; '' then cast(num
as int8) = 123123 else false end;&nbsp; -- error<br>
