如何使用ANSI SQL创建临时表？

Question

我想使用ANSI SQL创建一个临时表，以便我可以使用相同的查询在ORACLE和MSSQL中创建表。

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.
