急求助！！delphi7从SAP取数据(通过RFC接口)，中文数据被自动截断（附源代码）(200)

delphi7 取SAP中文地址数据，数据自动被截断，困惑两天了还没找到解决方案，用JAVA开发程序取数据就没有问题，难道是Delphi 变体变量（variant）存在的问题？请各位大虾指教，源代码如下，红色的那一行为被截断的变量值！谢谢了===================================================library PCZMIB07;{ Important note about DLL memory management: ShareMem must be the first unit in your library's USES clause AND your project's (select Project-View Source) USES clause if your DLL exports any procedures or functions that pass strings as parameters or function results.

没人回答，都沉下去了，自己顶一下！~

确定中文地址长度,SAP中是否有长度限制.

SAP中没有长度限制，相同的方法通过RFC取SAP数据，用JAVA实现就没问题！~

还是没有回答阿~难道没人处理过这类问题吗？

s6 := Table3.value(r,'STRAS');//检查下,对应 Table3的字段长度及字段数据类型,对于中文字符,建表sql中,考虑下改用 nvarchar()数据类型,试试看.

s6 := Table3.value(r,'STRAS');//检查下,对应 Table3的字段长度及字段数据类型,对于中文字符,建表sql中,考虑下改用 nvarchar()数据类型,试试看.----------------------------xj_lq大虾，谢谢关注，我说明一下，这里Table3定义的是variant类型的变量，用来保存SAP的RFC中对应表的数据，并不是一个表我怀疑是不是delphi的variant这种数据类型的存在BUG？有处理过这类问题请支招！~谢谢了

难道没人处理过这类问题？

你使用了com对象？那么用olevariant试验一下？或者直接用BSTR？

注意编码问题，如果JAVA直接读没有问题，说明可能是UTF-8编码的你用Delphi读出来后UTF8Decode一下试试，传参的时候也注意一下长度问题。没细看你的代码，猜测应该是这方面的原因。

最近比较忙，问题还没彻底解决，期待高手给予更明确一些的答案！~
