在PL-SQL觸發器中創建一個臨時表

Question

這可能是我看起來很愚蠢的東西。

我在觸發器中有此代碼。完整的觸發是在這裏：（有更多的代碼上面這段代碼）http://pastebin.com/KcBZdEmt

CREATE TABLE ApprList AS 
SELECT 
U.* 
FROM pmm$PmmReleaseRequest R 
INNER JOIN dbo$ManagedEntity ME 
ON ME.ManagedEntityID = R.ManagedSystemID 
INNER JOIN dbo$SmartRuleAssetCache SRC 
ON SRC.AssetID = ME.AssetID 
INNER JOIN dbo$UserGroup_SmartRule_Role GSR 
ON GSR.SmartRuleId = SRC.SmartRuleId 
AND GSR.RoleId IN (2,3) 
INNER JOIN dbo$AppUser_UserGroup UG 
ON UG.GroupID = GSR.UserGroupId 
AND UG.UserID <> R.UserID 
INNER JOIN dbo$AppUser U ON UG.UserID = U.UserID 
WHERE R.ReleaseRequestID = ReleaseRequestID 
AND U.UserID <> RequestorUserID; 

在folling行：

CREATE TABLE ApprList AS 

我得到：

Error(111,1): PLS-00103: Encountered the symbol "CREATE" when expecting one of the following:  (begin case declare end exception exit for goto if loop mod null pragma raise return select update while with <an identifier> <a double-quoted delimited-identifier> <a bind variable> << continue close current delete fetch lock insert open rollback savepoint set sql execute commit forall merge pipe purge 

這可能是最好採取在pastebin文件處出現峯值。

在此先感謝。

如果不使用EXECUTE IMMEDIATE，則不能混合使用DDL和DML語句。然而，在SQL Server中完美地創建表格的整個想法在Oracle中並不是最佳實踐。改爲使用全局臨時表。 創建該表，然後插入它從trigger.Something這樣的樣本

CREATE GLOBAL TEMPORARY TABLE YourSchema.Yourtable 
-- Create table 

( 
    pk_id   NUMBER(9) NOT NULL, 
    company   VARCHAR2(20 VARCHAR2) not null, 
    voucher_type VARCHAR2(3 VARCHAR2) not null, 
    voucher_no  NUMBER(10) not null, 
    year_period_key NUMBER not null 
) 
on commit PRESERVE rows;
