只需尝试为我指定的ID获取光标.
CREATE OR REPLACE PACKAGE some_package AS
TYPE t_cursor IS REF CURSOR;
TYPE t_id_table IS TABLE OF NVARCHAR(38) INDEX BY PLS_INTEGER;
PROCEDURE someentity_select(
p_ids IN t_id_table,p_results OUT t_cursor);
END;
CREATE OR REPLACE PACKAGE BODY some_package AS
PROCEDURE someentity_select(
p_ids IN t_guid_table,p_results OUT t_cursor)
IS
BEGIN
OPEN p_results FOR
SELECT *
FROM someschema.someentity
WHERE id IN (SELECT column_value FROM TABLE(p_ids)); - fails here
END;
END;
注意：someschema.someentity.id是一个NVARCHAR2(38)
PL / sql：ORA-00382：表达式类型错误
PL / sql：ORA-22905：无法访问非嵌套表项的行
我哪里错了？
在12.2之前的Oracle版本中,您只能通过CREATE TYPE语句从数据库中定义的集合类型中进行SELECT,而不是关联数组：

CREATE OR REPLACE PACKAGE some_package AS
PROCEDURE someentity_select(
p_ids IN t_guid_table,p_results OUT SYS_REFCURSOR);
END;
CREATE OR REPLACE PACKAGE BODY some_package AS

p_ids IN t_guid_table,p_results OUT SYS_REFCURSOR)

BEGIN
OPEN p_results FOR
SELECT *

WHERE id IN (SELECT column_value FROM TABLE(p_ids));
END;
END;
