我的数据类型错误：
ORA-01790：表达式必须与对应的表达式具有相同的数据类型
我已经检查了所有相同的数据类型。
这是我的代码：
SELECT CONTRACT_ID, DATEKEY, 'Projection', '1', OPEN_BALANCE,
PRINC_REPAYMENT, INTEREST, PAR_PREPAYMENT, FULL_REDEMPTION, REDRAW_AMOUNT, PRIN_DEFAULTS,
PRIN_RECOVERY, PRIN_DEL, INTE_DEL, DEL_PRIN_COLL, DEL_INT_COLL, CLOSE_PRIN_BAL, EXT_ID,
LAS_ACTIVE_FLG, PROD_ID, ASSET_TYP_ID, CPT_ID, ACCRETION, CASHFLOW_DT
FROM FACT_PWOR_CASHFLOW
WHERE ACTUAL_FLG = 'Y' AND LATEST_PROJ_IND = '0' AND LAS_ACTIVE_FLG = 'Y'
UNION
(SELECT CONTRACT_ID, DATEKEY_COLL, 'Actual', '1', SUM(OPENING_BALANCE) SUM_OPEN_BAL,
SUM(MI_PRINCIPLE) SUM_MI_PRIN, SUM(MI_INTEREST) SUM_MI_INTER, SUM(PARTIAL_PREPAYMENT) SUM_PAR_PREPAY,
SUM(FULL_REDEMPTION) SUM_FULL_REDEM, SUM(TTL_AMT_REDRAW) SUM_TTL_AMT,
'0', '0', '0', '0', '0', '0', SUM(CLOSING_BALANCE) SUM_CLOS_BAL, '0', 'Y',
PROD_ID, ASSET_TYPE_ID, CPT_ID, '0', COLLECTION_START_DT
FROM FACT_PWOR_COLLECTION
WHERE LAS_ACTIVE_FLG = 'Y'
GROUP BY CONTRACT_ID, DATEKEY_COLL, PROD_ID, ASSET_TYPE_ID, CPT_ID, COLLECTION_START_DT);
答案 0 :(得分：0)
在您的案例中使用UNION之类的设置操作时，所有匹配的列都会被列出来。表FACT_PWOR_CASHFLOW和FACT_PWOR_COLLECTION中的数据类型必须匹配。
例如，如果第一个ACCRETION语句中列SELECT的数据类型可能是integer，而第二个'0'中的相应列是SELECT string type语句为DataType Error，然后CONTRACT_ID发生。
删除SELECT列表中的所有列，然后尝试从第一个Update tmp Set
tmp.TenantReceipts = a.TenantReceipts,
tmp.OtherReceipts = a.OtherReceipts,
tmp.Disbursments = a.Disbursments,
tmp.AgentFeesCollectionCommission = a.AgentFeesCollectionCommission,
tmp.AgentFeesManagementFee = a.AgentFeesManagementFee,
tmp.AgentFeesBankCharges = a.AgentFeesBankCharges,
tmp.AgentOnlyCashMovements = a.AgentOnlyCashMovements,
tmp.PaidToOwners = a.PaidToOwners

开始逐步为两个SELECT语句添加列。
