我正在使用 IBM websphere commerce 和 db2,有以下代码
I am using IBM websphere commerce and db2, have following piece of code
Clob clobVar = null;
if (result.elementAt(3) != null)
clobVar = (Clob) result.elementAt(3);
if (clobVar == null) {
infoTable.put("EInfo", "");
} else {
stringTemp = clobVar.getSubString(1, (int) clobVar.length());
infoTable.put("EInfo", stringTemp);
}
代码运行良好,直到
clobVar = (Clob) result.elementAt(3);
但是一旦执行到
stringTemp = clobVar.getSubString(1, (int) clobVar.length());
系统抛出异常
[jcc][10120][11936][4.3.111] 无效操作:Lob 已关闭.ERRORCODE=-4470,SQLSTATE=null
我做错了什么?
如何解决这个问题?
这个问题可以通过在连接url中添加progressiveStreaming=2;
参数来解决
This issue can be solved by adding progressiveStreaming=2;
argument to the connection url
完整指定的连接 URL 如下所示:
The fully specified Connection URL was to be given as below:
jdbc:db2://localhost:50000/SAMPLE:progressiveStreaming=2;
如果您对该参数有异常,请在其中添加以下内容:
Incase you have exception on that parameter add the following to it:
jdbc:db2://localhost:50000/SAMPLE:driverType=4;fullyMaterializeLobData=true;fullyMaterializeInputStreams=true;progressiveStreaming=2;progresssiveLocators=2;
首选db2jcc4.jar
这篇关于Lob 已关闭.错误代码=-4470,SQLSTATE=null的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持跟版网!
