1，select curdate() /*2016-10-08*/2,select date_sub(curdate(), interval 6 day) /*2016-10-02*/
3,case when then else 拼接條件查詢：
where
(case when ifnull(@belongcity,'0')='0' or @belongcity='' then 1 else
cast(locate(@belongcity,worker_order.belong_city) as signed )
end)=1
and (case when ifnull(@energystation,'0')='0' then 1 else
cast(locate(@energystation,worker_order.repository_id) as signed )
end)=1
and (case when ifnull(@servicestatioin,'0')='0' then 1 else
cast(locate(@servicestatioin,worker_order.station_id) as signed )
end)=1
and date_format(worker_order.create_time, '%y-%m-%d') between date_format(cast(@begindatetime as datetime), '%y-%m-%d') and date_format(cast(@enddatetime as datetime), '%y-%m-%d')
group by date_format(worker_order.create_time,'%y-%m-%d');
或者是這種：
where
locate((case when ifnull(@belongcity,'0')='0' or @belongcity='' then worker_order.belong_city else @belongcity end),worker_order.belong_city)>0
and
locate((case when ifnull(@energystation,'0')='0' then worker_order.repository_id else @energystation end),worker_order.repository_id)>0
and locate((case when ifnull(@servicestatioin,'0')='0' then worker_order.station_id else @servicestatioin end),worker_order.station_id)>0
and date_format(worker_order.create_time, '%y-%m-%d') between date_format(cast(@begindatetime as datetime), '%y-%m-%d') and date_format(cast(@enddatetime as datetime), '%y-%m-%d')
group by date_format(worker_order.create_time,'%y-%m-%d');
4,拼接starttime和endtime:
set @begindatetime=(
case
when isnull(begindatetime) then
date_sub(curdate(), interval 6 day)
else
date_format(begindatetime,'%y-%m-%d')
end); /*起始時間*/
set @enddatetime=(
case
when isnull(enddatetime) then
curdate()
else
date_format(enddatetime,'%y-%m-%d')
end); /*結束時間*/
5,建立儲存過程及呼叫儲存過程：
drop procedure if exists pro_query_work_order_report;
create procedure pro_query_work_order_report (
in citycode varchar(32),/*城市code*/
in energystation int,/*能源站code*/
in servicestatioin int,/*網點code*/
in begindatetime datetime,/*開始時間*/
in enddatetime datetime/*結束時間*/
)begin
set @belongcity = citycode;/*所屬城市code*/
set @energystation=energystation; /*能源站code*/
set @servicestatioin=servicestatioin; /*站點code*/
set @begindatetime=(
case
when isnull(begindatetime) then
date_sub(curdate(), interval 6 day)
else
date_format(begindatetime,'%y-%m-%d')
end); /*起始時間*/
set @enddatetime=(
case
when isnull(enddatetime) then
curdate()
else
date_format(enddatetime,'%y-%m-%d')
end); /*結束時間*/
select
date_format(worker_order.create_time,'%y-%m-%d') as create_time,/*建立時間*/
( select count(0)
from biz_work_order tmp
where
date_format(tmp.create_time,'%y-%m-%d')=date_format(worker_order.create_time,'%y-%m-%d')
or (tmp.create_time
6,呼叫：（mysql 使用call進行呼叫，且不支援預設引數；sql server 使用exec進行呼叫，支援預設引數，有預設值的引數可以不傳）
call pro_query_work_order_report('50010',null,270,date_sub(curdate(), interval 6 day),curdate())發現mysql怎麼資料量大了，還沒有sql server好用。。。難道是我的幻覺麼。。

如何匯出Oracle的儲存過程為Sql語句
oracle中，過程 type 函式等物件的原始碼可以通過user source或dba source查詢 注意觀察查詢結果中，帶有line欄位，表示該段原始碼的行號。所以我們可以通過拼接 create or replace package 拼接查詢結果，生成建立過程 函式等的sql語句，舉例 se...
