php - MYSQL : Between or equal -


why not working if both value same use equal operator. user need select date & to, if user select both same date of & 2017-08-13 should still display dates of 2017-08-13 , unfortunately not working.

select * master_data.speed_of_service  ( trans_time >= '2017-08-13' ,  trans_time <= '2017-08-13')

it work if there interval between dates

if had guess, because trans_time has time component. 1 easy fix extract date:

select ss.* master_data.speed_of_service ss date(trans_time) >= '2017-08-13' , date(trans_time) <= '2017-08-13';

a better solution add 1 day "to" date:

select ss.* master_data.speed_of_service ss trans_time >= '2017-08-13' ,       trans_time < '2017-08-13' + interval 1 day;

this better because still allows use of index.

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() .
