---order by沒有where就是在前，而又多個列的組合條件在在后面

------------------2.-like的搜索------------------------
--不等于STU <> '黑色.均碼'值 模糊查詢+排序+分組

-------------------3.拼接字符-----------------------
--無效？？？50頁的知識

select top 10 BPSNAM +'/(con_content)' as 公司形象 from VF_TSTOSTOCK_UCML order by ITMCOD
--select top 10 BPSNAM ||'(con_content)' from VF_TSTOSTOCK_UCML order by ITMCOD --SQL不能用--其他的MYsql可以
--RIRIM函式，為確定格式化的資料，就比如拼接字串的空啊(sum )這些，-就在需要拼接的字串前面加RIRIM函式實作后變為(sum)
--LTRIM函式 （去掉串左邊的空格） TRIM(去掉兩邊的空格)
select top 10 * from VF_TSTOSTOCK_UCML
--計算欄位--就是計算他的總額 兩句差不多有點相識--
select top 10 BPSCOD,BPSNAM,ITMNAM,STOFCYName,STU,PCU*QTYPCU AS PQ from VF_TSTOSTOCK_UCML where BPSCOD ='Z999999'
select top 10 BPSCOD,BPSNAM,ITMNAM,STOFCYName,STU,PCU*QTYPCU AS PQ from VF_TSTOSTOCK_UCML order by BPSCOD DESC
--使用函式：CONVERT()--強轉日期 getdate() --獲取當前日期 SUBSTRING()--獲取串的組成部分
--MYSQL這個平臺使用--不同是CURDATE ---獲取當前日期
