本人收集的,挺有用的 1. 利用游标循环更新.删除MemberAccount表中的数据 DECLARE My_Cursor CURSOR --定义游标 FOR (SELECT * FROM dbo.MemberAccount) --查出需要的集合放到游标中 OPEN My_Cursor; --打开游标 FETCH NEXT FROM My_Cursor ; --读取第一行数据 WHILE @@FETCH_STATUS = 0 BEGIN --UPDATE dbo.MemberAccount SE…
[cursor]游标:用于循环表行数据,类似指针 格式如下: declare tempIndex cursor for (select * from table) --定义游标 open tempIndex --打开游标 fetch next from tempIndex into @x --抓取下一行数据给变量 --0表示抓取成功,1表示抓取失败,2表示不存在抓取行 begin --sql 语句 end close tempIndex --关闭游标 deallocate tempIndex -…
--循环 create or replace procedure p_xunhuan(input in number,output out number) is ); begin ; ..input loop begin output := input+temp; dbms_output.put_line('----'||output); end; end loop; end p_xunhuan; 运行存储过程: declare sr number;--输入参数 sc number;--输出参数…
用 游标(Cursor) + While循环 的方法, 对Customers表中的CompanyName列进行遍历 ) declare pcurr cursor for select distinct companyname from customers open pcurr fetch next from pcurr into @customer ) begin print (@customer) fetch next from pcurr into @customer end close p…
一,有子节点的部门的子节点的排序,调用子存储过程 CREATE OR REPLACE PROCEDURE "PRO_INIT_SORT" AS CURSOR cur_department_all IS select * from tbl_department; VAR_COUNT NUMBER ; VAR_OUT_COUNT NUMBER := 0; BEGIN FOR department_row IN cur_department_all LOOP SELECT COUNT(1)…
DECLARE @tablename VARCHAR(30),@sql VARCHAR(500)DECLARE cur_delete_table CURSOR READ_ONLY FORWARD_ONLY FORSELECT name FROM sysobjects WHERE name LIKE 'PUB%' AND type='U'OPEN cur_delete_tableFETCH NEXT FROM cur_delete_table INTO @tablenameWHILE @@FETC…
