问题描述
I am trying to select data from one table
and insert the data into another table
SELECT ticker FROM tickerdb;
Using OracleSql I am trying to
get the ticker symbol "GOOG" from the tickerdb table,
and insert the t.ticker into the stockdb table.
select from tickerdb table --> insert into quotedb table
INSERT INTO quotedb
(t.ticker, q.prevclose, q.opn, q.rnge,
q.volume, q.marketcap, q.dividend, q.scrapedate)
VALUES (?,?,?,?,?,?,?,?,SYSDATE)
tickerdb t inner JOIN quotedb q
ON t.ticker = q.ticker
解决方案
From the oracle documentation, the below query explains it better
INSERT INTO tbl_temp2 (fld_id)
SELECT tbl_temp1.fld_order_id
FROM tbl_temp1 WHERE tbl_temp1.fld_order_id > 100;
You can read this link
Your query would be as follows
//just the concept
INSERT INTO quotedb
(COLUMN_NAMES) //seperated by comma
SELECT COLUMN_NAMES FROM tickerdb,quotedb WHERE quotedb.ticker = tickerdb.ticker
Note: Make sure the columns in insert and select are in right position as per your requirement
Hope this helps!
