Question

I am new to this after spending 2 days trying to find an answer on the net
I am trying to construct a MYSQL select statement

I have 2 tables on ethat contains a list of dates and prices, the second is a table of reservation dates with start and end. I am tring to show al the FREE dates & prices in Table 1 that DO NOT exist in any of the reservation records in Table 2

Table 1 called – dates_prices –
id, date, price

example data

333, 2011-12-20, 66.00
333, 2011-12-21, 66.00
333, 2011-12-22, 66.00
333, 2011-12-23, 66.00
333, 2011-12-24, 66.00
333, 2011-12-25, 66.00
333, 2011-12-26, 66.00
333, 2011-12-27, 66.00
333, 2011-12-28, 66.00
333, 2011-12-29, 66.00
333, 2011-12-30, 66.00

Table 2 – reservations

id, startdate, enddate

example data

333, 2011-12-20, 2011-12-22
333, 2011-12-24, 2011-12-26
333, 2011-12-28, 2011-12-30

I need to extract ONLY the dates from Table 1 that do not exist in the Table 2 records between start and end dates of all records in table 2 with the same ID number 333

So the only records that should be displayed from table 1 are as follows

id, date, price

333, 2011-12-23, 66.00
333, 2011-12-27, 66.00
333, 2011-12-31, 66.00

Answer 1

create table  table12 (id int, datefor date, price int)

insert  into  table12
select 333, '2011-12-20', 66.00
union all
select 333, '2011-12-21', 66.00
union all
 select 333, '2011-12-22', 66.00
 union all
 select 333, '2011-12-23', 66.00
 union all
select 333, '2011-12-24', 66.00
union all
 select 333, '2011-12-25', 66.00
 union all
 select 333, '2011-12-26', 66.00
 union all
 select 333, '2011-12-27', 66.00
 union all
 select 333, '2011-12-28', 66.00
 union all
 select 333, '2011-12-29', 66.00
 union all
 select 333, '2011-12-30', 66.00 

 create table  table2 (id int, startdate date, enddate date)

insert  into  table2
select 333, '2011-12-20', '2011-12-22'
 union all
 select 333, '2011-12-24', '2011-12-26'
 union all
 select 333, '2011-12-28', '2011-12-30'

try this after creating above tables. solution to ur probelm is u need to make this type of query to tables ie
select * from table12 where datefor not between ‘2011-12-20’ and ‘2011-12-22’ and datefor not between ‘2011-12-24’ and ‘2011-12-26’ and datefor not between ‘2011-12-28’ and ‘2011-12-30’ and table12.id=333 i have made one proc just u need to pass ur id.

create proc solution( @id int) 
  as
  begin

declare @count int
    declare @i int
    declare @query varchar(800)
    set @query=''
 declare @startdate varchar(80)
    set @startdate=''
     declare @enddate varchar(80)
    set @enddate=''

 declare @table table( row int ,startdate date,enddate date,id int)
insert into @table select row_number() over(order by (select 1)) as rownumber  ,startdate,enddate,id  from  table2  where table2.id=@id
 set  @count=(select COUNT (*)  from  @table )
 set   @i=1
 set @query += 'select * from  table12 where '
while @count>=@i
begin
 set @startdate=( select startdate  from  @table  where row=@i) 
 set  @enddate =(select enddate  from  @table  where row=@i)
 set @query +=  ' datefor not between '+''''+@startdate+''''+ ' and '+'''' +@enddate+''''
 if   @count>@i
 begin
 set @query +=' and  '
 end
 if @count=@i
 begin
 set @query += ' and  table12.id='+cast (@id as varchar(50)) +''
 end 

set @i+=1
 end
 if(@i=1)
 set @query+='table12.id='+cast (@id as varchar(50)) +''


  exec (@query)
end

exec solution 333
