如何使用ANSI SQL創建臨時表？

Question

我想用ANSI SQL創建一個臨時表，這樣我就可以使用相同的查詢在ORACLE和MSSQL中創建表。

Answer 1

Create temporary table using the following statement 

CREATE GLOBAL TEMPORARY TABLE my_temp_table (
     id   NUMBER, 
     description VARCHAR2(20) 
    ) 
    ON COMMIT PRESERVE ROWS; 


    ON COMMIT PRESERVE ROWS clause indicates that rows should persist beyond the end of the transaction. They will only be removed at the end of the session.
