table中一个字段是数组, 当数组为空的时候怎么更新这个数组
快乐大法师 2015-02-26 10:07:34 当数组为空的时候,这条语句不包错。
update TABLE1 ES set
ES.SHUZU.AAA='4-13218695'
where ES.CASE_ID=5222348;
当数组为空的时候,错误如下
Ora-02309: atomic NULL violation
Cause: An attempt was made to acess the attributes of a null object instance.
Action: Ensure that the objcet instance is non-NULL before accessing
