六 連線模式 1） 連線簡介
可以借用 sql 的連線來解釋 假設 表a 表b 內連線 a.name b.name 儲存共有的相同值屬性 外連線 左外連線 以 外來鍵表a 左 屬性為基準。包含a屬性整列。b屬性符合a屬性值的存入，其餘b屬性被置為 null。右外連線 以 外來鍵表b 右 屬性為基準。包含b屬性整列。b屬性符合a屬...
13 連線查詢
假設 a 表中有3條記錄，b表中有 4 條記錄 那麼，語句select from a,b 會將a，b兩張表的資料交叉拼接起來，形成 3 4 12 條記錄的結果集，此結果集叫做笛卡爾積。ora 00918 未明確定義列 改進辦法 明確列的所屬 select empno,ename,emp.deptno...
004 連線查詢
再大多數的情況下,我們都需要進行連線查詢.笛卡爾積的產生 這個就是多表查詢的的最初結果集,那麼以後我們需要作的就是從結果集中篩選出需要的結果集.篩選的方式不同,導致sql的效率不同.篩選的方式就是加入連線標準.等值連線 select 字段 from 表1 表2 where 連線條件.eg 查詢員工名...
