Hi, I have two tables, one being a subset of the other. What I want to do is write a query that lists data in the larger table that is not in the smaller one. In effect I want to subtract the data in the smaller table from the larger table and list the remainder.
I have tried something like:
Select a.oem from a,b where a.oem not in (select b.man from b);
This query does not complete and I get 100% CPU usage :( . The largest of the tables has roughly 4000 records in it. Any ideas? Am I doing something wrong?
I have a table of timesheets that contains records for staff but it only contains weekly record if they have actually created that weeks record. I also have a table of weeks that contains all of the available weeks that time can be booked against.
How can I query the timesheet table against the weeks table and get a list of staff that have not created a record for that week ?
I have a field that will only get numeric values, numbers. And it will always have four characters or less. I do have times when I worry my data by over eighty's certain size or I average value, or both. Is this possible when using a text field.
I would like a query which would look at the difference between TBL_Sales and TBL_Finance and will then add rows to TBL_Sales to make them balance. In the example above I would want it to add the following (I've used C as a Product_Type to show that it's a manually entered value) -
what is the difference between creating a table using SQL and creating a table using MAOL (access object library)? I ran into these 2 methods when taking a tutorial on the internet? What are the advantages of each method?
I have a database with two tables, one for the amount that was estimated in each cost section, and one for the actual amount billed for each cost section. The tables have the same number of fields, all with the same names. They can be linked together with event ID. Each table has over 100 fields and I would like to find the difference between what was estimated and what the actual was for each event. I would also like to see which cost section has the most and least variance. I am trying to do this without going through each cost and putting [tEst].[CostName]-[tActual].[CostName].
What is the difference between "short text" and "long text"? Both seem to have 255 characters limit. I have Access 2013, and I found a solution, that you can use Memo instead of Short text. But the problem is, that there is no "memo" data type in Access 2013. So that won't work for me.
Could someone clarify the difference between DAO and ADO?
We migrated to Office 2003 last year - some large organizations move at the speed of continental drift. The database is written in Access 2002 (finally have most of it up and running - with thanks), but I need to really understand the difference for the documentation - to see if there are any issues that might undermine the database during the upgrade.
I have a Transactoin Table that holds the following fields:
TransID (*Primary Key Numerical Value) OrderID (Non Unique Number Value, One Order can have multiple Transactions attributed to it. Status (Numerical Value ranging from 0 to 32, each is a different phase in the life of a transaction such as 0 means Transation Created, 1 through 31 are various actions with 32 beign the transaction closing) Date (The date in which a particular phase of a particular transaction happened.) Reason (The Description of a phase. This is the only text field whose contents are relative to the Status field in the same table.)
I need to find the amount of time passed from the first Transaction to the last transaction of each individual order, which will be displayed in a report. Unfortunately not every order goes through all 32 phases, in fact most dont. The individual orders have a random amount of phases that they go through but each have a starting one (which ranges from 0 onwards) and an ending one (once again it is not necessarily 32). The dates correspond to the numbers in an individual order which means that if an order has the following phases:
1 2 4 6 Then the dates of each phase will be one after the other like the Status Number as shown above. Anybody knows how to do this? I need to find how much time passed from the first transaction to the last for each individual order qand display it in a report.
hey guys im not even sure if i have the heading right for this one. I have a table example data attached,
what i would like to do is return all transfers from that table where all the item numbers in a batch dont equal each other i.e if you subtract them all in a batch it doesnt = 0
i have know idea how to do this and dont know if this is even the right way of doing what i need which is to show transfers where some1 has transferred a product to a different one which we do want to have happen we just need to know when it was done.
I have an existing table with a field labelled Job Number (17 Job Numbers). Each month I import a new table and match each record via another field (serial number). For each new record, one or many, I want to attach a sequential Job Number. In this example the new job numbers need to start at 18 then 19 etc. How is this possible? I am fairly new to Access so please be gentle!. Cheers
Box 1 contains an employee's total weekly hours in hours and minutes: 40:00 Box 2 contains the actual total hours worked for the week: 35:30 Box 3 is the difference between Box 1 minus Box 2
I tried all the date/time functions to calculate the difference between Box 1 and Box 2 and none of them worked. I keep on getting an error message. Does anybody know how to calculate the difference between two sets of time (in hours and minutes)?
This code works perfectly and generates a new enquiry number for me.
The end user now wants to change the format of the number to read like this 06-0001, whereas before i was using 60001.
What i would like to know is there anyway i can increment the last 4 digits only? i.e remove the first 3 digits, 06-, increment the 0001 by 1 then reassemble them back together.
How do I calculate the values between two columns and populate a third column with those new values? I have an ''Actual Cost'' column and ''Budget Cost'' column and I would like to create a third column ''Margin.''
Is this something that needs to be done with a query or can it be handeled in the design view of a table? I'm starting to learn that Access works nothing like Excel.
Thank you in advance for any help. I scanned some of the threads in this forum, but many were beyond my comprehension. Any walk-through of this procedure would be much appreciated.
I am trying to get a very simple thing done in Access and I must have spent almost over 2 days of Internet time to do so. My problem is that I need to get the difference in 2 records to show in a query.
e.g. MyTable has 2 fields: 1. MyDate 2. MtrReading
Everyday I enter date in MyDate and a number in MtrReading. And I need to find out the difference between today's MtrReading and Yesterday's Mtr Reading.
Can someone tell me the difference between 'Call' and 'DoCmd' and how each are executed. For my level of programming, an newbie at that, I've used it interchangably so far without a problem. But I'm beginning to think that there is a difference. I don't want to later have to go back to redo my code down the line. I'm beginning to think that I've been very lucky so far in being able to use it interchangebly and my luck will run out soon.:eek:
Hello all!Maybe strange, but I have litterely created a new database from my "old" one. I did this because I thought the size of the database was growing way to fast.What I did was open two instances of Access, one with a new empty database open and one with the other "old" database open. I manually created all tables, queries, forms and code again by selecting everyting in design view, copying it, creating a new table/form/query/module in the empty database and pasting the data. After that I had to set some properties and it was ready to go. After compiling and compacting the new database was just 718kb in size. Empty that is. Then I added a couple of cases, compacted again, added some more, compacted again. (copies of the same data on different records). The same I did with the other "old" database.Both now have 12 clients with 2 cases (totalling 24 cases) every client and every case existing of the same data.The new database is now 1.120KB in size, the old one is 2.096KB. That's almost double. The only real difference between the two that I can think of is that one has a 20KB image tiled on the background of each form (the same image though) plus, of course, in the one database I've been designing, adding, deleting more.But how is it possible that these data sizes are so different? 100KB difference, ok. But almost double the size? How is that possbile and why? Are there things I can do to keep it at bay apart from using the Compacting and Reparing option? Plus: Is this normal?Edit: I emptied them. One is now 812KB in size empty, the other one is 1496 empty. Still... double the size. ?
I've just started a new job and one of the things they have got me doing involves getting some extra reports out of some access databases they have for the phone system. I've managed OK so far but I'm stuck on regarding phone diverts.
Basic jist is, when reception is unmanned they put the phone on divert and when they come back they take it off again. Simple and this info is recorded in the log file which is pulled into access each night.
The problem is all of the information is kept in a single table which I run a query on to get the info to look like below. The info is exactly as it is in the table, just that I have limited it to the reception user and where the func is like *54* or *55*:-
The FUNC *54* means put on divert and *55* is off divert. What I need to figure out is the time between each of *54* and *55* and total them for all the data in the table (we have a table for each month). The problem I can see here is that occasionally the receptionist will put in the *55* first which doesn't mean anything so this bit would need to be ignored as only bits where its a *54* followed by a *55*.
Hope this is self explaintory and that someone is able to help. I have attached a CSV fle on the table so you can have a play with it if you can help.
In access in one field I have one date and in another field I have another date. I want to calculate the number of years.,months and days elapsed between these two date. e.g. suppose in one field I have 30.06.2005 and in other 20.04.2004 then it should show 1 year 2 months and 10 days.
The query I would like, would only show me the result of Rows 2 & 4 because the value of cost is different between the weeks.
At the moment I have two queries, One that pulls out the last weeks value (WeekNo 1), and the other that pulls out the same information but for the comparison week (WeekNo 2). In the third query I created I linked the two columns from the Ref fields, but could not work the logic to only show me ones where the differences in cost were displayed.
Thanks in advance of the resolution to this. I know it is basic query work, but just have a logical block in getting it to work.
Worked Hours: DateDiff("h",[Start Time],[Finish Time])-[Breaks]
Start time and finish time appear as hh:mm and breaks is stored as a decimal i.e. 15min is 0.25, 30min is 0.5, 1 hour is 1.
The expression works fine when e.g Start 07:00 Finish 17:00 with breaks as 30min(0.5) gives the correct value of 9.5 hours worked but if the finish time was say 17:30, rather then show the correct value of 10 hours worked, it shows the wrong value of 9.5.
Could someone please tell me where I have one wrong and how to sort the problem, or offer me a different solution.
