请查看以下查询。 SQL没有它看起来那么糟糕。基本上，我们有一个事实表和一些简单的连接到一些维度表。然后我们有一个派生表的连接，给定别名ACCOUNTS-DIM-DEP

用户抱怨说，当他们的WebI（商业智能）报告在其过滤器中包含多个COST CENTER时，导致带有“IN”的SQL包含多个值，则返回以下错误：
[1]: (Error): ORA-01722: invalid number ORA-02063: preceding line from [dbname]
否则，对于单一的COST CENTER，报告工作正常。有趣的是，我注意到以下连接条件，我出现 UNRELATED ，对SQL产生了负面影响：
accounts_dim_dep.account_id = dw_mgr.fa_trans_fct.depreciation_account_id
这里的问题是左边的列accounts_dim_dep.account_id在db中定义为charchar，而右边的col，dw_mgr.fa_trans_fct.depreciation_account_id定义为数字。
当我修改连接条件以将数字转换为varchar ...
时accounts_dim_dep.account_id
= to_char(dw_mgr.fa_trans_fct.depreciation_account_id)
...无论过滤器中指定的COST CENTER数量如何，SQL都能正常工作。
我想知道一个看似无关的列上的类型不匹配会影响是否可以在IN列表中指定多个COST CENTER。
答案 0 :(得分：5)
ORA-02063错误表示远程数据库中发生ORA-01722错误。这符合（根据解释计划）RF_FND_FLEX_VALUES_DET表是远程的事实。
值accounts_dim_dep.account_id是flex_value的别名，它似乎是一个varchar2，几乎肯定包含非数字值。当您将其与数字列进行比较时，Oracle会对其应用隐式TO_NUMBER()，如果它遇到的值不是数字，则会使用ORA-01722失败。通过转换
dw_mgr.fa_trans_fct.depreciation_account_id到字符串，避免隐式转换。
那么，为什么原始查询只有一个成本中心才会成功，但是当你有几个成本中心时会失败？无法访问您的数据来运行某些测试，或者至少不同版本的解释计划，很难确定。但是您发布的解释计划显示远程操作仅从RF_FND_FLEX_VALUES_DET检索一行。我猜测当你运行带有多个成本中心的查询时，它会拉回一大堆行，其中包括flex_value具有非数字值的行。

如果您启用了PLW错误，那么您之前就会收到警告 - 您已经获得了“远离类型转换”错误。我重新写了你的查询：
SELECT t.period,
t.asset_cost_company_code,
t.asset_cost_center_id,
t.depreciation_account_id,

FROM DW_MGR.FA_TRANS_FCT t
JOIN DW_MGR.PROJECTS_DIM pd ON pd.project_num = t.project_num
JOIN DW_MGR.ORGANIZATIONS o ON o.cost_center_id = t.asset_cost_center_id
AND o.company_code = t.asset_cost_company_code
JOIN (SELECT TO_NUMBER(rffvd.flex_value) 'account_id',
rffvd.description
FROM RF_FND_FLEX_VALUES_DET rffvd
WHERE rffvd.flex_value_set_id = '1002363'
AND rffvd.summary_flag = 'N'
GROUP BY rffvd.flex_value,
rffvd.description) add ON add.account_id = t.depreciation_account_id
WHERE t.period IN ('01-Jun-2009')
AND t.asset_cost_center_id IN ('000296','000296') --doesn't work
AND t.asset_cost_company_code = '0007'
更新日志：
TO_NUMBER(RF_FND_FLEX_VALUES_DET.flex_value)，以便转换发生在JOIN 我不知道为什么在IN子句中的2个以上条目上会发生ORA错误，但是你提供了两个与你发布的相同的错误，那么它不太可能是数据问题。
