I am creating an online booking system & need to exclude closed days from being booked & need a select query to see if the "date" (Christmas day) is >= [ClosedFrom] AND <= [ClosedTo]
Both ClosedFrom & ClosedTo are datetime columns in SQL Server 2008.
Here is what my table look like:
----------------------------------------------------------
ClosedDateID -- ClosedFrom -- ClosedTo
----------------------------------------------------------
1 -- 2010-12-24 -- 2010-01-04
2 -- 2011-04-20 -- 2010-04-20
----------------------------------------------------------
The query below will hopefully show you what I am trying to achieve:
SELECT [ClosedFrom],[ClosedTo]
FROM [Package.Closed.Dates]
where '2010-12-25' >= [ClosedFrom] AND '2010-12-25' <= [ClosedTo]
Thanks in advance for your help ;)
UPDATE:
Thanks Refilter for your answer but I still cannot get this to work :( I have include some more details below.
Here is my table script:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[Package.Closed.Dates](
[ClosedDateID] [int] IDENTITY(1,1) NOT NULL,
[ClosedDate] [datetime] NULL,
[ClosedFrom] [datetime] NULL,
[ClosedTo] [datetime] NULL,
CONSTRAINT [PK_Package.Closed.Dates] PRIMARY KEY CLUSTERED
(
[ClosedDateID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
Here is my table data:
INSERT INTO [dbo].[Package.Closed.Dates]
([ClosedDate]
,[ClosedFrom]
,[ClosedTo])
VALUES
('2010-12-25'
,'2010-12-20'
,'2010-12-28'
GO
Here is my query to that checks a single date (ClosedDate) to see if we are closed (THIS RETURNS "we are CLOSED that day" - WORKING):
if exists (
SELECT [ClosedDate]
FROM [Package.Closed.Dates]
where [ClosedDate] = '2010-12-25'
)
select 'we are CLOSED that day'
else
select 'we are OPEN that day'
Here is your query to that checks between two dates (ClosedFrom & C开发者_运维技巧losedTo) to see if we are closed (THIS ALWAYS RETURNS "we are OPEN that day" - NOT WORKING):
if exists (
SELECT [ClosedFrom],[ClosedTo]
FROM [Package.Closed.Dates]
where '2010-12-25' between [ClosedFrom] AND [ClosedTo]
)
select 'we are CLOSED that day'
else
select 'we are OPEN that day'
I have also tried the below query (THIS ALWAYS RETURNS "we are OPEN that day" - NOT WORKING):
if exists (
SELECT [ClosedFrom],[ClosedTo]
FROM [MWD.Package.Closed.Dates]
where '2010-12-25' >= [ClosedFrom] AND '2010-12-25' <= [ClosedTo]
)
select 'we are CLOSED that day'
else
select 'we are OPEN that day'
Just one other quick note, I need to see if the "date" (Christmas day) is >= [ClosedFrom] AND <= [ClosedTo]
SELECT [ClosedFrom], [ClosedTo]
FROM [Package.Closed.Dates]
where '2010-12-25' between [ClosedFrom] AND [ClosedTo]
This might work for you. This removes time component and makes it 00
DECLARE @DateToCheck DATETIME
SET @DateToCheck = '2010-12-25'
IF EXISTS ( SELECT 1
FROM [Package.Closed.Dates]
WHERE CONVERT(DATETIME,@DateToCheck,112) BETWEEN CONVERT(DATETIME,
[ClosedFrom],112) AND CONVERT(DATETIME,[ClosedTo] ,112)
)
SELECT 'we are CLOSED that day'
ELSE
SELECT 'we are OPEN that day'
