不同的单据根据日期和单据流水自动生成顺序的单号。
解决办法:
create or replace procedure proc_id_builder(id varchar2, sn out varchar2) AS
rowt int;
upperID varchar2(64);
begin
upperID := upper(id);
select count(*) into rowt from ts_parameter where parameterid = upperID;
if rowt = 0 then
sn := to_char(sysdate, 'YYMMDD') || '000001';
insert into ts_parameter values (upperID, sn, '');
commit;
return;
end if;
select parametervalue into sn from ts_parameter where parameterid = upperID for update;
if substr(sn, 1, 6) > to_char(sysdate, 'YYMMDD') then
sn := '';
return;
end if;
--生成单号
if substr(sn, 1, 6) < to_char(sysdate, 'YYMMDD') then
sn := lpad(to_char(sysdate, 'YYMMDD') || '000001',12,'0');
else
sn := lpad(to_char(to_number(sn) + 1),12,'0');
end if;
--更新单号
update ts_parameter set parametervalue = sn where parameterid = upperID;
commit;
EXCEPTION
WHEN OTHERS THEN
ROLLBACK;
lfguser.proc_log_ora_exception(p_err_Num => SQLCODE,
p_err_Msg => SQLERRM,

end;
