接下来我的最后一个问题(
Table Variables in Oracle PL/SQL?)…
一旦你在数组/表中有值,你又怎么把它们重新出来呢？最好使用select语句或类似的东西？
这是我到目前为止
declare
type array is table of number index by binary_integer;
pidms array;
begin
for i in (
select distinct sgbstdn_pidm
from sgbstdn
where sgbstdn_majr_code_1 = 'HS04'
and sgbstdn_program_1 = 'HSCOMPH'
)
loop
pidms(pidms.count+1) := i.sgbstdn_pidm;
end loop;
select *
from pidms; --ORACLE DOESN'T LIKE THIS BIT!!!
end;
我知道我可以使用dbms_output.putline()输出它们,但我希望从任何其他表中选择一个结果集.

您可能需要一个GLOBAL TEMPORARY TABLE.
原文链接：https://www.f2er.com/oracle/204952.html在Oracle中,这些被创建一次,然后被调用时,数据对你的会话是私有的.
尝试这样的东西…
CREATE GLOBAL TEMPORARY TABLE temp_number
( number_column NUMBER( 10,0 )
)
ON COMMIT DELETE ROWS;
BEGIN
INSERT INTO temp_number
( number_column )
( select distinct sgbstdn_pidm
from sgbstdn
where sgbstdn_majr_code_1 = 'HS04'
and sgbstdn_program_1 = 'HSCOMPH'
);
FOR pidms_rec IN ( SELECT number_column FROM temp_number )
LOOP
-- Do something here
NULL;
END LOOP;
END;
