3.使用DEFINE定义替代变量 在Oracle中除了可以使用“&&”定义替代变量之外,还可以使用DEFINE命令来定义替代变量,用户可以利用DEFINE命令创建一个字符型的替代变量,而且此种方式定义的替代变量会一直保存到一个SESSION的操作结束或者是遇见UNDEFINE清除变量。 如果不需要任何替代变量的定义,可以输入SET DEFINE OFF指令. ...
The scope of a local variable is the batch in which it's declared. A table variable isn't necessarily memory resident. Under memory pressure, the pages belonging to a table variable can be pushed out totempdb. You can define an inline index in a table variable. ...
