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;
