[解决办法]
set @mySql= 'select * from oa_alarm_center where ' ', ' '+isRead+ ' ', ' ' not like ' '%, ' '+cast( '+@userId+ ' as nvarchar)+ ' ',% ' ' and status <> 2 and status <> 3 '

改

set @mySql= 'select * from oa_alarm_center where ' ', ' '+isRead+ ' ', ' ' not like ' '%, '+cast(@userId as nvarchar)+ ',% ' ' and status <> 2 and status <> 3 ' --此句需要做修改

[解决办法]
复制语句要用 ' '引起来
[解决办法]
--改一处：
/*
if(@userPosition=2)--业务部主管
begin
set @exeSql=case when flowType= 'orderFlow ' then @mySql when flowType= 'makeFlow ' then @mySql when flowType= 'sheetBuy ' then @mySql else ' ' end
if(@exeSql <> ' ') exec(@exeSql)
end
*/
if(@userPosition=2)--业务部主管
begin
set @exeSql = @mySql + ' and flowType in( ' 'orderFlow ' ', ' 'makeFlow ' ', ' 'sheetBuy ' ') '
exec(@exeSql)
end
[解决办法]
有一点:当需要给SQL语句中的变量加上单引号的时候要多加一个,可以试试print ' ' ' '

set @exeSql=case when flowType= 'orderFlow ' then @mySql when flowType= 'makeFlow ' then @mySql when flowType= 'sheetBuy ' then @mySql else ' ' end
