                  问题描述

                  我正在尝试从一张表中选择数据
                  并将数据插入到另一个表中

                  I am trying to select data from one table
                  and insert the data into another table

                      SELECT ticker FROM tickerdb;
                  

                  我正在尝试使用 OracleSql
                  从tickerdb表中获取股票代码GOOG",
                  并将 t.ticker 插入到 stockdb 表中.

                  Using OracleSql I am trying to
                  get the ticker symbol "GOOG" from the tickerdb table,
                  and insert the t.ticker into the stockdb table.

                  从tickerdb表中选择-->插入到quotedb表中

                  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
                  

                  推荐答案

                  从 oracle 文档中,下面的查询更好地解释了它

                  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;
                  

                  您可以阅读此链接

                  您的查询如下

                  //just the concept    
                      INSERT INTO quotedb
                      (COLUMN_NAMES) //seperated by comma
                      SELECT COLUMN_NAMES FROM tickerdb,quotedb WHERE quotedb.ticker = tickerdb.ticker
                  

                  注意:确保插入和选择中的列根据您的要求位于正确的位置

                  Note: Make sure the columns in insert and select are in right position as per your requirement
