c# - RollBack all executed query -


how can rollback executed query on 1 transaction in mysql query executed in c# 

if (cn0.state != system.data.connectionstate.open) cn0.open();             cm0.connection = cn0;             cm0.commandtext = "set autocommit=0 ";             cm0.executenonquery();             cm0.commandtimeout = 0;//unlimited              tr = cn0.begintransaction(system.data.isolationlevel.serializable);             cm0.transaction = tr;              try             {                 cm0.commandtext = "create table if not exists i2019.produkh i2019.karyawanh ";                 cm0.executenonquery();                  cm0.commandtext = "create table if not exists i2019.profileh i2019.karyawanh ";                 cm0.executenonquery();                  cm0.commandtext = "create table if not exists i2019.customerh i2019.karyawanh ";                 cm0.executenonquery();                  cm0.commandtext = "create table if not exists i2019.supplierh i2019.karyawanh ";                 cm0.executenonquery();                  cm0.commandtext = "insert i2019.produkh (idx,idh,idb,faktur,tglb,jmlb,ket,edit,bf,modifat) " +                     "select idx, idh, idb, faktur, tglb, jmlb, ket, edit, bf, modifat karyawanh.t1 jmlb < 0";                                 cm0.executenonquery();                  tr.commit();                 if (cn0.state != system.data.connectionstate.closed) cn0.close();                 tr.dispose();             }             catch             {                 tr.rollback();                 if (cn0.state != system.data.connectionstate.closed) cn0.close();                 tr.dispose();                 throw;             }

but error when execute query on create supplierh table rollback , closing connection.

and hope table :

  • produkh
  • profileh
  • customerh
  • supplierh

is not created, because there error on other

but after rolled supplierh table rolled , other not rolled back.

please tell me how?

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
