VARGRAPHIC vs .LONG VARGRAPHIC

watsonyaya

有一点不太明白

VARGRAPHIC(n)

A variable-length graphic string. The range of n is 1 to 16 336 double-byte characters.

LONG VARGRAPHIC

A variable-length graphic string. The maximum length is 16 350 double-byte characters.

这俩到底有啥区别阿
不会就是LONG VARGRAPHIC比VARGRAPHIC(n)可以多放一些double-byte characters吧

那位能讲一讲LONG VARGRAPHIC用在那些场合

好老的帖子啊！
还是说一下自己的看法吧！

LONGVARGRAPHIC 是不能指定最大长度的，VARGRAPHIC是可以的
