Oracle生成单据编号存储过程的实例代码

Oracle生成单据编号存储过程,在做订单类似的系统都可能会存在订单编号不重复,或是流水号按日,按年,按月进行重新编号。

可以参考以下存储过程

CREATE OR REPLACE
procedure Pro_GetBillNO(TypeTable in varchar2,cur_mycursor out sys_refcursor)
as
DReceiptCode varchar2(40);
DReceiptName varchar2(50);
DPrefix1 varchar2(50);
DISO varchar2(50);
DIsAutoCreate varchar2(20);
DPrefix2 varchar2(20);
DPrefix3 varchar2(20);
DDateValue date;
DNO number;
DLength number;
DResetType number;
DSeparator varchar2(20);
DReturnValue varchar2(50);
strSql varchar2(1000);
begin
DReturnValue:=”;
select “ReceiptCode”,”ReceiptName”,”Prefix1″,”ISO”,”IsAutoCreate”,”Prefix2″,”Prefix3″,”DateValue”,”NO”,”Length”,”ResetType”,”Separator” into
DReceiptCode,DReceiptName,DPrefix1,DISO,DIsAutoCreate,DPrefix2,DPrefix3,DDateValue,DNO,DLength,DResetType,DSeparator from
“SysReceiptConfig” where “ReceiptCode”=TypeTable;
if to_number(DResetType)>0
then
if DIsAutoCreate=1 THEN
if DResetType=1 then –按年份
if to_number(to_char(sysdate,’yyyy’)) <>to_number(to_char(DDateValue,’yyyy’)) then
update “SysReceiptConfig” set “NO”=1,”DateValue”=to_date(sysdate) where “ReceiptCode”=TypeTable;
else
update “SysReceiptConfig” set “NO”=”NO”+1 where “ReceiptCode”=TypeTable;
end if; –年份
end if;–DResetType=1
if DResetType=2 then –按月份
if to_number(to_char(sysdate,’MM’)) <>to_number(to_char(DDateValue,’MM’)) then
update “SysReceiptConfig” set “NO”=1,”DateValue”=to_date(sysdate) where “ReceiptCode”=TypeTable;
else
update “SysReceiptConfig” set “NO”=”NO”+1 where “ReceiptCode”=TypeTable;
end if; –月份
end if;–DResetType=2
if DResetType=3 then –按日
if to_number(to_char(sysdate,’dd’)) <>to_number(to_char(DDateValue,’dd’)) then
update “SysReceiptConfig” set “NO”=1,”DateValue”=to_date(sysdate) where “ReceiptCode”=TypeTable;
else
update “SysReceiptConfig” set “NO”=”NO”+1 where “ReceiptCode”=TypeTable;
end if; –月份
end if;–DResetType=3
else
update “SysReceiptConfig” set “NO”=”NO”+1 where “ReceiptCode”=TypeTable;
end if;–DResetType
end if;
strSql:=’ select * from “SysReceiptConfig” where 1=1 ‘;
strSql:=strSql ||’ and “ReceiptCode”=”’||TypeTable||””;
open cur_mycursor for strSql;
end;
