Question

我在将for循环变量传递给显式声明的游标时遇到问题。这是PL / SQL代码：

    DECLARE

count_total number := 0;

i           number :=0;

ch          varchar(10) := 'abc';

ch2         varchar(10) := 'xyz';


CURSOR cursor_sim_b IS **--identifying if value is garbage--**
select a1,a2, a3, a4, a5, a6,
trim(translate(a1,'0123456789',' ')),
trim(translate(a2,'0123456789',' ')),
trim(translate(a3,'0123456789',' ')),
trim(translate(a4,'0123456789',' ')),
trim(translate(a5,'0123456789',' ')),
trim(translate(a6,'0123456789',' '))
from  temp_clean;

sim_b_rec cursor_sim_b%rowtype;

BEGIN

dbms_output.put_line('OUTSIDE the CURSOR ');

FOR sim_b_rec IN cursor_sim_b

LOOP

dbms_output.put_line('OUTSIDE the FOR LOOP ');

FOR i IN 1..6
LOOP
ch := 'a' ||i;

if sim_b_rec.ch is not null  **--ERROR--**

then
BEGIN

execute immediate 'update temp_clean
set sim_b_rec.%ch = NULL';

EXCEPTION

 WHEN  OTHERS THEN

   ROLLBACK;

END;

DBMS_OUTPUT.PUT_LINE('a'||i||'<' || ch || '>');

end if;
END LOOP;
END LOOP;
END;
/

获得以下错误： PLS-00302：组件＆＃39; CH＆＃39;必须声明

有没有办法将变量传递给光标？

怎么样： update temp_clean set a1=case when trim(translate(a1,'0123456789',' ')) is not null then null else a1 end, a2=case when trim(translate(a2,'0123456789',' ')) is not null then null else a1 end, a3=case when trim(translate(a3,'0123456789',' ')) is not null then null else a1 end, a4=case when trim(translate(a4,'0123456789',' ')) is not null then null else a1 end, a5=case when trim(translate(a5,'0123456789',' ')) is not null then null else a1 end, a6=case when trim(translate(a6,'0123456789',' ')) is not null then null else a1 end
