Question

我有一个安装脚本，我试图根据远程数据库中的表创建多个视图。该脚本将在多个数据库上执行，每个数据库都有自己的远程数据库。我打算在安装过程中提示远程数据库链接作为输入参数，而不是创建脚本的多个版本。但是，当我执行安装脚本时，第一个视图将失败并显示ORA-02019，而其余视图已成功创建。

样本测试版本：

install.sql

Set serveroutput on

SET VERIFY OFF
Alter Session Set current_schema =  TEST;
SET VERIFY ON

DEFINE DB_LINK = &&db_link

PROMP Install started ...

@./SCRIPTS/views.sql

PROMP Install ended

quit

@。/ SCRIPTS / views.sql

--View1
Create or replace View tmp_cards as Select nvl((select count(*) from auths@&db_link where  cardid = t.id),0) cnt_auths,t.* From Cards@&db_link t ;

--View2
Create or replace View tmp_Auth as Select * From auths@&db_link;

安装日志

old   1: Create or replace View tmp_Auth as Select * From auths@&db_link
new   1: Create or replace View tmp_Auth as Select * From auths@db02

View created.

Install ended

如果我直接通过PL / SQL中的命令窗口创建视图，则第一个视图成功创建

SQL> Create or replace View tmp_cards as Select nvl((select count(*) from auths@db02 where  I002_NUMBER = t.cardnumber),0) cnt_auths,t.* From Cards@db02 t;
View created

我错过了什么？
