sql - Why are the dates between a given range not getting picked? -


i trying pick dates between ranges. have hard coded date , month year dynamically concatenated it. trying pick dates between these ranges table doesn't give dates between given range.

declare @year varchar(10) set @year= '2017-2018'  declare @yearfrom varchar(15) set @yearfrom= (select substring(@year, 1, 4) ) declare @yearto varchar(15) set @yearto= (select substring(@year, 6, 9) )  set @yearfrom= '01-07-'+@yearfrom set @yearto= '30-06-'+@yearto  select convert(varchar(11),c.registrationdate,106)  contractors c convert(varchar(11),c.registrationdate,106) between convert(varchar(11),@yearfrom,106)  , convert(varchar(11),@yearto,106)

the registration date saved as:

yyyy-mm-dd e.g. 2017-07-03

another way solve using datefromparts, year, month , day inputs converted dates, follows:

declare @year varchar(10) set @year= '2017-2018'  declare @yearfrom int set @yearfrom= (select substring(@year, 1, 4) )   declare @yearto int set @yearto= (select substring(@year, 6, 9) )   declare @startdate date set @startdate = datefromparts(@yearfrom,1,7)  declare @enddate date set @enddate = datefromparts(@yearto,6,30)

now can use @startdate , @enddate in comparison registration date.

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() .
