我目前有这些表:
CREATE TABLE #SECURITY_TEMP (ID CHAR(30))
CREATE TABLE #SECURITY_TEMP_PRICE_HISTORY (ID CHAR(30), PRICEDATE DATE, PRICE FLOAT)
CREATE TABLE #SECURITY_POST (ID CHAR(30), SECPOS int)
INSERT INTO #SECURITY_TEMP (ID) VALUES ('APPL') ,('VOD'),('VOW3'), ('AAA')
INSERT INTO #SECURITY_TEMP_PRICE_HISTORY (ID,PRICEDATE, PRICE) VALUES
('APPL', '20150101',10.4), ('APPL', '20150116',15.4), ('APPL', '20150124',22.4),
('VOD', '20150101', 30.5), ('VOD', '20150116',16.5), ('VOD', '20150124',16.5),
('VOW3', '20150101', 45.5), ('VOW3', '20150116',48.8) ,('VOW3', '20150124',50.55),
('AAA', '20100118', 0.002)
INSERT INTO #SECURITY_POST (ID,SECPOS) VALUES ('APPL', 100), ('VOD', 350), ('VOW3', 400)
我希望有一个干净的表格,在通过日期时向我显示安全ID,安全位置以及该安全性的最新可用价格.
现在,当我执行以下操作时:
SELECT sec.ID, sec.SECPOS, t.PRICE
FROM #SECURITY_POST as SEC …
