如何将AP代码的SQL代码转换为PL / SQL

Question

我有以下代码在SQL Developer中完美运行，但我需要在APEX的进程块中输入代码，它只给我一个PL / SQL选项。以下是我写的代码：

BEGIN
truncate table TEMP_UPLOAD;
Merge into INVOICE b
USING (
 SELECT CUSTOMER_CLASS,RULE_AGGREGATOR,BA
 FROM CUSTOMER_TEMP_UPLOAD
 WHERE CUSTOMER_CLASS = 'CUSTOMER88') u
ON (b.BA = u.BA)
WHEN MATCHED THEN UPDATE SET b.CUSTOMER88_DATE_UPDATED = sysdate
WHEN NOT MATCHED THEN
  INSERT (b.CUSTOMER_CLASS,b.RULE_AGGREGATOR,b.BA,b.CUSTOMER88_DATE_ADDED)
  VALUES (u.CUSTOMER_CLASS,u.RULE_AGGREGATOR,u.BA,sysdate);

UPDATE INVOICE a 
    SET a.CUSTOMER88_DATE_REMOVED = sysdate
    WHERE BA IN 
        (select b.BA 
 from INVOICE b 
 left join CUSTOMER_temp_upload u 
 on b.BA = u.BA 
 where u.BA is null and b.CUSTOMER_CLASS = 'CUSTOMER88');
 END;

获得以下错误

1 error has occurred
•ORA-06550: line 3, column 14: PLS-00103: Encountered the symbol "TABLE" when expecting one of the following: := . ( @ % ;

Answer 1

错误消息指向您的TRUNCATE TABLE命令。

TRUNCATE是一个DDL命令 - 不要从PL / SQL中调用它。相反，请使用DELETE以使您的流程具有事务安全性。

（P.S。技术上可以使用EXECUTE IMMEDIATE从PL / SQL运行DDL - 但我不建议它）

Answer 2

似乎问题是它不喜欢我的BEGIN和END;大写。当我把它改为开始和结束时;以及将TRUNCATE表命令更改为删除，然后接受它并且PL / SQL命令按预期工作。
