3.6 Variadic Macros A macro can be declared to accept a variable number of arguments much as a function can. The syntax for defining the macro is similar to that of a function. Here is an example: #define eprintf(...) fprintf (stderr, __VA_ARGS__) Th

Microsoft SQL SERVER 数据库存储过程,根据其输入输出数据,笼统的可以分为以下几种情况或其组合:无输入,有一个或多个输入参数,无输出,直接返回(return)一个值,通过output参数返回一个或多个值,返回一个记录集(recordset).无论哪一种情况,无论输入输出参数多复杂的存储过程,都可以在易语言中正确调用,准确的传入参数,并获取正确的输出数据.下面我(liigo)分多种情况介绍在易语言中调用MS SQL SERVER数据库存储过程的详细方法,使用数据库操作支持库(eD
