Question

我在事务中插入记录，然后我通过Oracle函数检索相同的记录。 oracle函数没有返回任何记录。我的DBA告诉我，Oracle函数不在事务中运行。我该如何解决这个问题？

实施例：使用oracle提供程序开始事务

执行一些SQL：

INSERT OWNER （FIRST_NAME，LAST_NAME） VALUES （'JOHN'，'SMITH'）

从函数中获取事务中的记录（71是示例ID）： select * from table（GET_OWNER_DETAILS_FNC（71））

这是Oracle功能：

CREATE OR REPLACE FUNCTION "AROH"."GET_OWNER_DETAILS_FNC" (p_owner_information_oid  in aroh_owner_information.owner_information_oid%type ) 
return OWNER_DETAILS_TABLE_TYPE_FNC

IS 
PRAGMA AUTONOMOUS_TRANSACTION; 

v_owner_details_set   OWNER_DETAILS_TABLE_TYPE_FNC := OWNER_DETAILS_TABLE_TYPE_FNC();

CURSOR c_owner_dtls IS

Answer 1

AUTONOMOUS_TRANSACTION pragma意味着该函数在单独的事务的上下文中运行。默认情况下（参见http://docs.oracle.com/cd/B19306_01/server.102/b14220/consist.htm#sthref1972），这使用“读提交”隔离级别，这意味着，当事务查询数据时，它只查看在查询开始之前提交的数据。由于您插入的数据尚未提交，这意味着该功能无法查看。

Answer 2

来自Oracle Docs：

AUTONOMOUS_TRANSACTION pragma改变子程序在事务中的工作方式。标有此pragma的子程序可以执行SQL操作并提交或回滚这些操作，而无需在主事务中提交或回滚数据。

你能尝试摆脱那个pragma吗？

最后，“我的DBA告诉我Oracle功能不在事务中运行”是值得怀疑的。我不是专家，但我真诚地怀疑这是否正确。
