Question

Please check out the following query. The SQL isn’t as bad as it looks. Basically, we have a fact table and some simple joins to some dimension tables. Then we have a join to a derived table, given the alias ACCOUNTS-DIM-DEP

  SELECT dw_mgr.fa_trans_fct.period,
         dw_mgr.fa_trans_fct.asset_cost_company_code,

The users were complaining that when their WebI (business intelligence) report included multiple COST CENTERS in their filter, resulting in a SQL with an “IN” include multiple values, the following error was returned:

   [1]: (Error): ORA-01722: invalid number ORA-02063: preceding line from [dbname]

Otherwise, for a single COST CENTER, the report worked fine. The interesting part is that I noticed that the following join condition, which to me appears UNRELATED, was negatively impacting the SQL:

accounts_dim_dep.account_id = dw_mgr.fa_trans_fct.depreciation_account_id

The problem here is that the column on the left, accounts_dim_dep.account_id, is defined in the db as a charchar and the col on the right, dw_mgr.fa_trans_fct.depreciation_account_id, is defined as a number.

When I modified the join condition to convert the number to a varchar…

accounts_dim_dep.account_id 
                       = to_char(dw_mgr.fa_trans_fct.depreciation_account_id)

…the SQL works regardless of the number of COST CENTERS that are specified in the filter.

I’d like to know how a type mismatch on one seemingly unrelated column affects the whether one can specify multiple COST CENTERS in the IN list.

If you had PLW errors enabled, you’d have been alerted to the situation earlier – you’d have gotten a “conversion away from type” error. I re-wrote your query:

SELECT t.period,
       t.asset_cost_company_code,
       t.asset_cost_center_id,
       t.depreciation_account_id,
       add.description, 
       pd.project_num,
       pd.project_name,
       ROUND(t.activity_deprn_amount_us, 2),
       o.major_geography,
       o.business_unit || o.bu_desc,
       o.industry_sector_num || o.industry_sector_desc,
       o.hyperion_num,
       o.hyperion_desc,
       o.hyperion_reporting
  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'

Changelog:

• Save yourself some typing by using table aliases (also makes it easier for others to read & help)
• Removed: hyperion_organization was a join to the same table, using the same criteria
• Specified TO_NUMBER(RF_FND_FLEX_VALUES_DET.flex_value) so the conversion occurs before the JOIN

I don’t know why the ORA error would occur on 2+ entries in the IN clause, but it you provide two of the same as you posted then it’s not likely to be a data issue.
