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 p_w_picpath 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。
