2. Syntax Errors(句法错误) 当你把一个SAS程序提交后,你希望它能正确运行,并显示出你希望看到的结果,但有时候,由于你的疏忽或其他某种原因,你的SAS程序中存在一些错误,导致它不能正确运行。这时,你就需要找到错误并改正它。`在SAS程序中,最常见的,也是最容易发现的一类错误是句法错误,句法错误大致包括 1) 关键...
因此,SAS hash对象不能处理一些复杂的连接逻辑,例如范围或模糊匹配。 SAS hash对象只能在数据步骤中使用,而PROC SQL可以在任何地方使用。因此,SAS hash对象有一些语法和作用域的限制,例如不能使用宏变量或函数来定义键或数据变量。 SAS hash对象在数据步骤结束后会自动消失,而PROC SQL会生成一个持久的数据集。因此,...
