Teradata 3706，預計介於DISTINCT和LEFT關鍵字之間

Question

我在這裏試圖使用JOIN和SELECT更新查詢，但我面臨3706錯誤。

這裏是錯誤行 -

 
UPDATE A0619IL3549_D_RPT.RPT_IS_ELIGIBILITY A2 
FROM 
(SELECT A.REP_CD, A.GEO_CD,A.MONTH_ID, B.IC_PRD AS IC_PAYOUT_FLAG, 
COALESCE(CASE 
WHEN UPPER(B.IC_PRD) = 'SEMESTERLY' THEN A.CURR_SEMESTER_FLAG 
WHEN UPPER(B.IC_PRD) = 'QUARTERLY' THEN A. CURR_QUARTER_FLAG 
ELSE '0' 
END,'0') IC_PAYOUT_FLAG 
FROM 
A0619IL3549_D_RPT.RPT_IS_ELIGIBILITY A, 
(
SELECT DISTINCT LEFT(B. REP_CD, POSITION('-' IN B.REP_CD)-1) AS REP_CD,C.GEO_CD,IC_PRD FROM 
A0619IL3549_D00_IC_MAIN.ICDM_GEO_REP_PROD A, A0619IL3549_D00_IC_MAIN.ICDM_DIM_REP B,
A0619IL3549_D00_IC_MAIN.ICDM_DIM_GEO_HIER C 
WHERE 
A.REP_SK=B.REP_SK 
AND A.GEO_SK=C.GEO_SK 
AND A.RUN_ID = (SELECT MAX(RUN_ID) FROM A0619IL3549_D00_IC_MAIN.ICDM_GEO_REP_PROD) 
) B 
WHERE 
A.REP_CD = B.REP_CD 
AND 
A.GEO_CD = B.GEO_CD)A1 
SET A2.IC_PAYOUT_FALG = A1.IC_PAYOUT_FLAG 
WHERE 
A1.REP_CD = A2.REP_CD 
AND 
A1.MONTH_ID = A2.MONTH_ID 
AND 
A.GEO_CD = A2.GEO_CD 

Answer 1

LEFT不是TD15.10之前有效Teradata的功能，這是ODBC SQL，這是自動的，但僅適用於SELECT翻譯。

使用有效的語法來代替：

SUBSTRING(B. REP_CD FROM 1 FOR POSITION('-' IN B.REP_CD)-1)
