『壹』 sql一個表A有多列數據是字母，需要關聯字典表B，將這多列字母轉為漢字。
selecta.*,b1.漢字,b2.漢字fromAa
leftjoinBb1ona.欄位1=b1.欄位
leftjoinbb2ona.欄位2=b2.欄位
如果有再多欄位就後面 left join 往上加

『叄』 sql 語句 急！！！！ 數據將英文和數字去掉,只保留漢字的sql語句
1、創建測試表，
create table test_replace_str(value varchar2(200));
4、編寫語句，將英文和數字去掉,只保留漢字；
select t.*, regexp_replace(value, '[a-zA-Z0-9]', '') sec
from test_replace_str t;

『陸』 sql 正則表達式 替換字母+數字
我不知道你用的是什麼資料庫,下面我給你一個Oracle資料庫的替換掉(-N+數字)的例子
update[dbo].[Winit庫存]set[商品編號]=REGEXP_REPLACE([商品編號],'-Nd+','')
不同的資料庫,用的可以用正則表達式的replace函數不一樣
SQL Server中我不知道你那裡有沒有dbo.RegexReplace函數,是不是還要現建這個替換函數
update[dbo].[Winit庫存]set[商品編號]=dbo.RegexReplace([商品編號],'-Nd+','',1)
下面是建立RegexReplace函數的sql語句
