im making a system and part of that system is the booking of the library
2 classes can be in the library at once i want a way where if a 3rd teacher tries to book a slot then theyll be told its not available if only one class was allowed itd be easy, by using a compound key but cos 2 classes are allowed this is a bit hard for me lol trying to think of a way to allow 2 bookings but not more any ideas? thanks
I am trying to create a query that will count the number of bookings in january and a seperate count for the number of bookings in february from a table called booking order. im using the start date as the date to tell which month the booking was in. This is what i have come up with but it doesn't work and i am not to sure where to go from here. select count(jan.[booking no]), count(feb.[booking no]) from [booking order] jan, [booking order] feb where jan.[booking no].[start date] > 31/12/2006 and < 01/02/2007 and feb.[booking no].[start date] > 31/01/2007 and < 01/03/2007;
I would like to display a page that tells the user that there are no "bookings" for TODAY. It is a restaurant booking database which I have nearly completed. When there are bookings for TODAY, it shows a table with the customers booked for today (that's working ok), but if there aren't any for 'today' when I open that page, it just shows the headings of the table with no customers. I'd like to just display a message (and no table elements) when there aren't any bookings for today. Pretty confusing explanation? sorry bout that.
Could someone check the following code. i've set up a form for creating regular bookings, and have a field, for which you type in the frequency in days you want the bookings for. (ie, 7 days for every week on that day, 14 for every two weeks etc...) and it seems to work, however it just alters the one record, instead of creating entirely new ones. Could someone please help:
Private Sub cmdCreate_Click() Dim date2 As Date Dim period As String Dim cost2 As Currency Dim frequency2 As Integer
Do While year = actual_year
date2 = Date_For period = Time_Period cost2 = Cost frequency2 = Frequency
Date_For = date2 + frequency2 Time_Period = period Cost = cost2 Frequency = frequency2
DoCmd.Close acTable, "tblRegularBookings" Loop
End Sub
Also, one of the other problems i'm trying to solve is for those who want to create a regular booking but on say every third monday of the month for example.
I have Trainee, Staff, Course, and Booking tables and forms. Everything is working fine but I want to limit the amount of bookings per course to 50, how would I go about doing this?
I want to create a calendar to show some bookings. I have a table [tblShootDates] with some fields, the most important being [ShootDate]. I also have a [ShootDateID] which is an Autonumber and is the Primary Key. I should add that it has a Prefix "Shoot ID" 000000.
I want the calendar to show each day that a booking has taken place and the text to show is the [ShootDateID]
I have a form which allows the user to book rooms.
On this form, there are the following fields:
BookingID: (Autonumber) RoomID: Text box Time:Text Box Date: Text Box Class: Text Box Teacher: Text Box
The form adds this information to the Booking table.
What I'm looking to do is prevent the user from double booking a room,like being able to check if the Room is already booked at that time and date, before the new information is added to the table and the room becomes double booked.
Basically this would be checking the RoomID, Time and Date fields, as everything else is irrelevant. What would be the best way to do this?
I work across a number of small venues which have art cases that can be booked for displays. I am trying to build a simple data base to report what space is available and also what art is currently being displayed. The art is usually booked by month, but sometime it can be booked for a week etc.
I have set up 3 tables
Art Inventory
Art Cases by Venue
Art Case Bookings
In the art case booking form, I have set up the start and end date but I cannot figure out how to avoid double bookings of a case? Once I have that worked out I believe I know how to build the required reports for my needs.
I am supposed to make a database for a hotel system, how I could prevent double bookings.
My Reservation Table has the following fields:
Reservation No. (PK) Room No. (FK) Customer ID (FK) Payment ID(FK) Reservation In Date Reservation Out Date
Together with preventing double bookings is there a way automatically that can mark in the Room Table, the status as "available" or "booked" automatically by looking at the date today?
I have built a query to calculate the expiry dates of training courses but I am trying to input a criteria so that only dates within 90 days of todays date show. I am using Date()<90 but it doesn't return the correct information. What the criteria should be for this?
I have a table of records, which has within it two date fields (effectively, a 'start' and 'end' date for that particular record)
I now need to create a query to perform a calculation for each date between the 'start' date and the 'end' date
So the first step (as I see it anyway) is to try to create a query which will give me each date between the two reference dates, in the hope that I can then JOIN that onto another query to perform the necessary calculation for each of the returned dates.
Is there a way to do this?
So basically, if for a particular record, the 'start' date is 01-Apr-2015 and the 'end' date is 09-Apr-2015, can I produce a dataset of 9 records as follows :01-Apr-2015
(The *obvious* solution would be to create a separate table of dates, from which I could just SELECT DISTINCT <Date> Between #04/01/2015# And #04/09/2015# - but that seems like a dreadful waste of space, if that table is only required to generate the above? And it would have to cover all possible options; so it would either have to be massive, and contain every possible date - ever! - or maintained, adding new dates as necessary when they are required. Seems horribly inefficient!)
Is it possible to just select each date between the two reference dates? Or can you only query something which exists somewhere in a table?
I have a database with 5000 entries, corresponding to about 10 entries for about 500 people. Each of the entries is dated, and I need to calculate the time intervals between each person's sequential entries in the table.
One way of doing this is to create another column that contains the date of the previous entry. I can then use DateDiff to subtract one date from the other and give me the difference in days.
This approach falls down if I then work with only a subset of the entries - I would have to re-enter the previous entry dates as the time intervals would have changed.
What I really need is a way of subtracting the date from the date in the cell directly above it. Will Access let me do this, or is there a better way?
I have two tables with dates. Between (!) every two following dates in table1, I want to know the number of dates in table2. How do I write an SQL query for this? The tables I have are up to a few hundred records in table 1 and a few thousand records in table2. So to prevent that this takes hours I need a fast query.
To explain the query I need, for example: table1 01/01/2014 15/01/2014 17/01/2014 30/01/2014
Explanation: Between 01/01/2014 and 15/01/2014 in table 1 there are 2 dates in table2 (01/01/2014 is not included between the dates) Between 15/01/2014 and 17/01/2014 in table 1 there are 0 dates in table 2 Between 17/01/2014 and 30/01/2014 in table 1 there are 4 dates in table 2
I have a master table which shows all transactions per record (person) over a financial year.
Each record person has a seperate package period over which their spend needs to be measured. Therefore although I have all their transactions for the year, I only want to sum their transactions between their given [start date] and [end date] which are in columns.
I need to be able to create a field which sums all expenditure per record between the start and end dates
Name Start Date End Date Invoice Date Amount
Matt 15/5/11 15/9/11 1/11/11 £100 Matt 15/5/11 15/9/11 7/7/11 £200 Matt 15/5/11 15/9/11 12/12/11 £200
In this case I would only want to sum 7/7/11 as this is between the start and end dates
I want to write something like sumif([Invoice Date] is between [start date] and [end date] - not sure where or how exactly
(The start date and end date will always be the same per person)
Please bear with me here as it's a little involved.
I'm doing a staff profile website which includes a section where they can enter their annual/other leave details.
I decided to store their leave in two fields Start_Date | End_Date rather than each individual date that they took - the short and wide approach vs long and narrow.
This has left me needing to do a query that would return all the dates between the start and end dates inclusive.
I appreciate i could do this using some script to loop through a recordset and build an array of dates but i wondered/hoped that it could be done using SQL.
As it is an asp page i can't use user defined functions in a VBA module in Access so the solution would need to be pure SQL.
I have a scenario where the first three rows of date which have dates of 4/1, 4/4/ 4/6 with ndc 5513026701; next six rows that have dates from 4/8 to 4/20 with ndc 5513014801; next three rows that have dates from 4/25, 4/27, 4/29 with ndc 5513026701.
The issue I am having is I do not know how to have separate min/max dates for ndc 5513026701 since when I group by ndc 5513026701 min = 4/1 ; max = 4/29. I need to have min = 4/1 and max = 4/6 for one row and another row of min = 4/25 and max = 4/29.
Any easy way to sequentially create min/max for each ndc 5513026701? I wasn't sure how to verbalize this so I have attached a sample worksheet.....
I'm not sure if I am biting off more than I can chew. I have a text field in each record in my database (Inherited) The db has nearly 5,000 records. I would like to split the field into records in a seperate table. An Example of the table as is now;
Is this possible in one hit or do I need to process the records without dates first and then run another process to split those with Dates? I say dates but the field is a text field. About 15-20% of the records contain dates which are always enclosed in parenthesis.
I have a client that wants to enter a range of dates in a query of when they will call that person back. Then they want to be able to type in a range of dates and have a make table query show them all the people that fall in between these two dates....is this even possible??? Ex. Joe March 3 to March 8 Mary March 4 to March 9 John March 5 to March 10
So if they type into the query March 3 to March 6 all three people should show up because one of the dates specified lies within the parameters they are asking for.....man I am out of ideas
I want to add Hours to a date value. For example the date value=05/04/2005 18:12:35 I want to add three hours to that date value so the new date value will be 05/04/2005 21:12:35. Is there operatior to add dates.
Set db = CurrentDb() str = "SELECT ID, Date, Item, QtyRec, QtyIssue FROM DailyIssue Where Date >= '" & SDate & "' AND DATE <='" & Edate &"'" Set rs = db.OpenRecordset(str, dbOpenSnapshot)
But it is not working at all. Error message is Data Type Mismatch.
i've been reading about the us/uk date problem and found some helpful threads such as http://www.access-programmers.co.uk/forums/showthread.php?t=39675 but would like to ask (cause i'm still a bit confused):
if someone enters all of the dates into an .mdb the same way, either day-month-year or month-day-year, will the dates somehow be stored correctly regardless of the system's setting? (in this case, entered day-month-year into u.s. system-settings).
i have seen how access flips "wrong" dates. if i understand correctly, the dates are then actually stored "flipped", or wrongly.
is there some way of making the wrong dates (the ones that have been flipped) right again?
also, how does one view the dbl-precision number that is stored?
