在Oracle的游标中，能select * from table 这个table是变量吗create or replace procedure testas cursor
在Oracle的游标中，能select * from table; 这个table是变量吗
create or replace procedure test
as
cursor ctables is select * from all_t_pk;
each_row ctables%rowtype;
table_name varchar(255);
column_name varchar(255);
maxId number;
begin
open ctables;
loop
fetch ctables into each_row;
exit when ctables%notfound;
table_name := each_row.table_name;
column_name := each_row.column_name;
--问题就在这个代码，我想column_name 和table_name 都是变量？？
select max(column_name) into maxId from table_name;
dbms_output.put_line(table_name||'-'||column_name);
end loop;
end test;
加了这句就通过不了：
select max(column_name) into maxId from table_name;
能否这样动态指定字段和表呢？？大侠们，急救!!!
下面是游标遍历的表。都是些表和主键。
select * from all_t_pk;
TABLE_NAME COLUMN_NAME

如不能，有替代方案吗？？？
[解决办法]
这个需要用动态SQL拼凑。
sqlstr := 'select max('
[解决办法]
column_name
[解决办法]
') from '
[解决办法]
table_name;
execute immediate into maxId;
