如何在没有得到错误或NULL值的情况下将MEMPTR复制到LONGCHAR变量或从LONGCHAR变量复制MEMPTR? [英] How to Copy MEMPTR to/from a LONGCHAR variable with out getting error or NULL value?

问题描述

在使用GET-STRING将MEMPTR的值复制到LONGCHAR变量时，出现错误9324.有什么解决办法吗?

while copying the value of a MEMPTR to a LONGCHAR variable using GET-STRING, i got an error 9324 . Is there any solution ?

我已经尝试过了:

function x returns longchar():
  DEF VAR i_xml_string AS LONGCHAR NO-UNDO.
  DEF VAR i_mem        AS MEMPTR   NO-UNDO.
  p_doc:SAVE("memptr":U, i_mem).
  COPY-LOB FROM i_mem TO i_xml_string.
  return i_xml_string.
end.

但是出现以下错误:

推荐答案

GET-STRING对普通字符串进行操作.它们的大小限制为大约31,000字节.使用COPY-LOB来获取MEMPTR数据进出LONGCHAR.

GET-STRING operates on ordinary character strings. Those are limited in size to around 31,000 bytes. Use COPY-LOB to to get MEMPTR data in and out of LONGCHAR.

类似的东西:

copy-lob from my_memptr to my_longchar.

PUT也仅限于普通CHAR字符串.如果要使用LONGCHAR和MEMPTR，则需要使用COPY-LOB.

PUT is also restricted to ordinary CHAR strings. If you want to work with LONGCHAR and MEMPTR you need to use COPY-LOB.
