问题:

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

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!
