oralce in 查询不能传入字符串
declare
var_catids varchar2(256) default '';
int_pp integer default 0;
begin
var_catids :='1640,1633,1635';
select max(pp) into int_pp from table1 where id in (var_catids);
dbms_output.put_line('int_pp:'||int_pp);
end;
把select max(pp) into int_pp from table1 where id in (var_catids);这语句换成如下就正常了
select max(pp) into int_pp from table1 where id in (1640,1633,1635);
哪位高手帮我看看.

temp_sql:='select max(pp) from table1 where id in ('||var_catids||')';
