SUM(LN(B.YIELD_RATE + 1)) - 1
FROM RISK.TB_GUD_RATE B, RISK.TMP_TMP A
WHERE B.TRADEDATE BETWEEN A.BEGIN_DATE AND A.END_DATE
AND A.TIME_WINDOW = '2'
AND B.DATA_TYPE IN (0, 1, 2, 7)

GROUP BY A.END_DATE, B.FUND_CODE, B.DATA_TYPE, B.PARAM_1
这句SQL执行N久没出来，但换了个函数，LN换成SIN
SELECT A.END_DATE,
B.FUND_CODE,
'2',
B.DATA_TYPE,
B.PARAM_1,
SUM(SIN(B.YIELD_RATE + 1)) - 1
FROM RISK.TB_GUD_RATE B, RISK.TMP_TMP A
WHERE B.TRADEDATE BETWEEN A.BEGIN_DATE AND A.END_DATE
AND A.TIME_WINDOW = '2'
AND B.DATA_TYPE IN (0, 1, 2, 7)
AND B.TIME_WINDOW = '1'
GROUP BY A.END_DATE, B.FUND_CODE, B.DATA_TYPE, B.PARAM_1
0.7秒返回结果。各位大大给下分析结果谢谢。
