以下的文章主要介紹的是Oracle多條件查詢的分頁存儲實際操作過程,以下的文章主要是介紹一種更為快捷的方法來實現其實際操作過程,以下就是具體方案的描述,希望在你今後的學習中會有所幫助。
項目接近尾聲了,感覺將業務邏輯放到Oracle中使得後台代碼很精簡,Oracle很有搞頭!
PL\SQL:
create or replace procedure proc_clIEnt_List --客戶Oracle多條件查詢
(
pro_cursor out pkg_order.p_cursor, --查詢結果集
characters_ in varchar2,--客戶性質
states_ in varchar2,--客戶狀態
type_ in varchar2,--客戶類型
calling_ in varchar2,--客戶行業
name_ in varchar2,--客戶名稱
beginTime_ in date,--創建日期上限
endTime_ in date,--創建日期上限
area_ in number,--客戶地區
clIEntsource_ in varchar2,--客戶來源
importent_ in varchar2,--重要程度
start_row in number,--結果集起始行
end_row in number--結果集結束行
