sql - Oracle Convert Char to Date -


i have following date in oracle table:

'2017-08-01 00:00:00,000000000'

i want convert date using following don't know how deal zeroes?!

. . . t.execution_local_date_time between to_date('2017-08-01  00:00:00,000000000', 'yyyy-mm-dd hh:mi:ss') , to_date('2017-08-10 00:00:00,000000000', 'yyyy-mm-dd  hh:mi:ss');

could me this?

oracle dates not support milliseconds. assuming execution_local_date_time column date, following comparison best can do:

t.execution_local_date_time between to_date('2017-08-01 00:00:00', 'yyyy-mm-dd hh:mi:ss') ,         to_date('2017-08-10 00:00:00', 'yyyy-mm-dd hh:mi:ss');

if wanted convert text string milliseconds timestamp, use this:

to_timestamp ('2017-08-01 00:00:00,000000000', 'yyyy-mm-dd hh:mi:ss,ff')

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() .
