其中，表TB_GOS_ACCOUNT_O_LOTINVEN中字段INVBALQTY为not null，并且设有default value；而上面的SQL是将TB_GOS_ACCOUNT_O_LOTINVEN"."INVBALQTY"字段 更新为NULL。

   查看trail 文件信息：发现捕获字段有PK、LASTMODIFYTIME、INVBALQTY三个字段的信息，但是INVBALQTY 字段捕获到的信息没值，为空。

   看了表的属性后，追查到做了数据变更的源SQL语句，更新INVBALQTY 字段为0，当时猜想这里的0应该跟字段上属性default value 设置有关。

   其实这是ogg 11R2 的CDR（Conflict Detection and Resolution,当前环境OGG的版本是11.2.0.1）参数设置问题导致的，加上参数NOCOMPRESSUPDATES，使当前更新的SQL完整捕获到列INVBALQTY的值。问题得以解决。原参数文件配置中已添加过NOCOMPRESSDELETES。 以下是CDR的参数要求：

The extract capture for CDR should include the following

Force extract to capture the before image using GETBEFORECOLS in the TABLE parameter.

Use NOCOMPRESSDELETES and NOCOMPRESSUPDATES in the extract parameter file so that to have extract write a full record in a trail instead of the changed columns only.

其它的可以参考ogg的相关资料做进一步了解，在此不复述。
