将GWT与CMS结合使用（如Vosao）(Using GWT with CMS (like Vosao))

 （1）当错误13600的文本引用“第二个错误消息”时，它表示堆栈中的下一个错误 - 在本例中为QSM-03112。 
 
 （2）我相信错误的原因是调用TUNE_MVIEW中的第二个参数意味着CREATE MATERIALIZED VIEW语句的全文，但是您只传递查询文本。 
 
 （3）对于多行问题，如果你使用显式的PL / SQL匿名块而不是“execute”，我期望它可以工作，例如： 
 
BEGIN
  :mvddl := 'create materialized view MV_FOO_BAR
             build immediate
             refresh fast on commit
             ...
            ';
END;
/

(1) When the text for error 13600 refers to the "second error message", it means the next error in the stack -- in this case QSM-03112.
 
(2) The reason for the error, I believe, is that the second parameter in the call to TUNE_MVIEW is meant to be the full text of a CREATE MATERIALIZED VIEW statement, but you are passing just the query text.
 
(3) For the multi-line issue, I expect it will work if you use an explicit PL/SQL anonymous block instead of "execute", e.g.:
 
BEGIN
  :mvddl := 'create materialized view MV_FOO_BAR
             build immediate
             refresh fast on commit
             ...
            ';
END;
