1、可以在运行时包含WITH RECOMPILE。这告诉SQL Server抛弃已有的执行计划并且创建一个新的计划-但只是这一次。也就是说,只是这次使用WITH RECOMPILE选项来执行存储过程。 EXECspMySproc'1/1/2004'WITHRECOMPILE 2、也可以通过在存储过程中包含WITH RECOMPILE选项来使之变得更持久。 如果使用这种方式,则在CREATE PROC...
You can also pass parameters to a stored procedure, so that the stored procedure can act based on the parameter value(s) that is passed. 我理解类似于编程里的函数,每次使用或者重复使用的话就进行调用。 语法 创建存储过程 1. CREATE PROCEDURE precedure_name ...
