其中:
<selectKey keyProperty="qiCode" resultType="java.lang.String" order="BEFORE"> select 'QI' || to_char(sysdate,'yyyymmdd') || lpad(seq_qi_id.nextval,4,'0') as QI_CODE from dual </selectKey>` 即為主鍵生成規(guī)則; 先創(chuàng)建一個(gè)序列seq_qi_id 寫一個(gè)存儲過程用于每天初始化序列從0開始:
create or replace procedure CLEARSEQ_QI as n_count number(8); begin select count(1) into n_count from user_sequences t where t.sequence_name = 'SEQ_QI_ID';
if n_count > 0 then
execute immediate 'drop sequence SEQ_QI_ID';
end if;
execute immediate 'create sequence SEQ_QI_ID
minvalue 1
maxvalue 99999999
start with 1
increment by 1
NOCYCLE
NOCACHE';
commit;
end;
每天需要對該存儲過程計(jì)數(shù)清零:
create or replace package body PG_CLEAR_ALL_SEQ is
PROCEDURE mainproc aS
procedure_name varchar2(40) := 'PG_CLEAR_ALL_SEQ.mainproc';
BEGIN
rlog.info(procedure_name, 0, '', 'Start,iv_id is PG_CLEAR_ALL_SEQ' );
COMMIT;
clearseq_qi();
COMMIT;
rlog.info(procedure_name, 0, '', 'Finished,iv_id is PG_CLEAR_ALL_SEQ');
COMMIT;
EXCEPTION
WHEN OTHERS THEN
rlog.except(procedure_name,
'1',
SUBSTR(SQLERRM, 1, 512),
SUBSTR(DBMS_UTILITY.format_error_backtrace, 1, 512));
COMMIT;
END;
end PG_CLEAR_ALL_SEQ;
(附加)根據(jù)主表單號生成對應(yīng)下一級明細(xì)條目號:
<selectKey keyProperty="modelItemCode" resultType="java.lang.String" order="BEFORE"> select #{modelCode} || '_' || lpad((decode(max(to_number(substr (m.MODEL_ITEM_CODE,18))), null, 0, max(to_number(substr(m.MODEL_ITEM_CODE,18)))) + 1),2,'0') from T_VD_INDICATORS_MODEL_DETAIL m where m.MODEL_CODE = #{modelCode} </selectKey>
