sql - Can anyone tell me what is wrong with my query? -

- 

select      t1.description, t1.type, t1.salespotential , t2.startdate,       t3.project_region, t3.job_type      sysdba.opportunity t1,     select t1.type, count(*)     opportunity     group by type, join      sysdba.activity t2 on t1.accountid = t2.accountid join      sysdba.c_opportunity_ext t3 on t1.opportunityid = t3.opportunityid      closeprobability > 70

the line "group by type," has bad syntax.

use 1 by. type reserved word. if refers field, use `type` (surround field name ` character). comma @ end shouldn't there.

group `type`

if using mysql, it's practice put sub-queries inside parentesis. becomes "derived table" , needs name. i've used "sometemptable" in example:

(select t1.type, count(*)     opportunity     group `type`) sometemptable

c# - TransactionScope not rolling back although no complete() is called -

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
