Oracle - subprogram or cursor c_tab is out of scope
提问by Jan Maděra
create or replace procedure CV8_POCET_RADKU(p_schema VARCHAR2, p_razeni IN varchar2 default 'asc') as
i_dotaz varchar2(200) := 'select count(*) from ';
i_pocet number;
cursor c_tab is
select object_name
from dba_objects where object_type = 'TABLE'
and owner = upper(p_schema)
order by object_name asc;
i_tab c_tab%rowtype;
begin
dbms_output.put_line('Tabulky ze schematu: ' ||p_schema);
open c_tab;
loop
fetch c_tab into i_tab;
exit when c_tab%notfound;
execute immediate i_dotaz || p_schema||'.'||i_tab.object_name into i_pocet;
dbms_output.put_line(c_tab.object_name || ' - '|| i_pocet || 'radku');
end loop;
close c_tab;
end;
Oracle give me a error subprogram or cursor c_tab is out of scope. I think i have the cursor right.
Oracle 给我一个错误 subprogram or cursor c_tab is out of scope。我想我的光标是正确的。

The problem is in the line which reads:
问题出在以下行中：
dbms_output.put_line(c_tab.object_name || ' - '|| i_pocet || 'radku');
You can't refer to c_tablike this - instead, refer to the row variable you read the data into:
您不能c_tab像这样引用- 相反，请引用您将数据读入的行变量：
dbms_output.put_line(i_tab.object_name || ' - '|| i_pocet || 'radku');
Best of luck.
祝你好运。
