ALTER TRIGGER [dbo].[TRIGGER_INSERT_PROJECT_INFO]

AFTER INSERT
AS

declare @interval_day int,@oper_cond varchar(10)
declare @pStartTime datetime,@pEndTime datetime,@Id int,@pType int,@pTypeChild int,@pTypeChildZhuanye int

--检验游标cur_insert的存在性，如果存在就删除
if cursor_status('global', 'cur_insert') <> -3
or cursor_status('local', 'cur_insert') <> -3
begin
deallocate cur_insert
end

--添加时触发
if exists(select 1 from inserted)
begin
declare cur_insert cursor local for
select Id,pName,pStartTime,pEndTime,pType,pTypeChild,pTypeChildZhuanye,pCreateUser from inserted

open cur_insert --打开游标
fetch next from cur_insert into @Id,@pName,@pStartTime,@pEndTime,@pType,@pTypeChild,@pTypeChildZhuanye,@pCreateUser
while @@fetch_status = 0
begin

if not exists(select * from exc_projrun_t where ProjectID=@Id)
BEGIN

insert into exc_projrun_t(ProjectID,OperatingCondition,NodeName,PreviousNode,ProjectState,UpdateTime)
values(@Id,@oper_cond,'登记审核','项目登记','运行中',Current_Timestamp);

END

--下一行
fetch next from cur_insert into @Id,@pName,@pStartTime,@pEndTime,@pType,@pTypeChild,@pTypeChildZhuanye,@pCreateUser
end

close cur_insert

deallocate cur_insert
end
