Question

需要基于集合值在where子句中添加条件。
    create or replace type item_type force as object ( key number(3), value varchar2(20) ) create or replace type item_coll force as table of item_type create or replace type req_type force as object ( rule varchar2(20), items item_coll )     procedure sample( in_a IN req_type, out_b OUT ret_coll) as select * bulk collect into out_b from tab_test a where a.rule= in_a.rule;     示例：
    Input string : req_type('aaa',item_coll(item_type(1,'A'),item_type(2,'B'),item_type(3,'C')));     最终查询应该像
    Select * bulk collect into out_b from tab_test a where a.rule= in_a.rule and ((a.key = 1 and a.value = 'A') OR (a.key = 2 and a.value = 'B') OR (a.key = 3 and a.value = 'C'))
有人可以建议解决方案吗？

Answer 1

也许还有其他方法，但这对我有用：

select item_type(a.key, a.value)
  bulk collect into out_b
  from tab_test a
  where in_a.rule = a.rule 
    and (a.key, a.value) in (select key, value from table(in_a.items));

Answer 2

select item_type(a.key, a.value)
   bulk collect into out_b
   from tab_test a
   where in_a.rule = a.rule 
   and exists (select 'x' 
                  from table(in_a.items) i
                  where a.key = i.key
                  and a.value = i.key);
