Hello, im having a real problem running a certain query in access. My database is used to monitor drain spillages, and the query im trying to build needed to look down a column and show descrite water spills. A descrite spill is when water spills for a bit then stops. I need to show how many times this happens in a column.
The complexity of the problem (comparing one value in a column to other values in that column) coupled with the size of the dataset (600K+ rows) just baffles everything I throw at it.
I had two stabs at it. One involved a recordset - looping through and updating a new field. Recordsets can cause database bloat - in this case it bloated the db to 2GB (Accesses maximum size causing the code to crash) - this is something I've never managed before. The other involved a function that left access frozen.
I was really stuck on this until a crazy idea came to mind, i want to know if this would work.
This might sound stupid but how about some crazy thing like adding a new column and numbering the fields, then adding some kind of query that says if the value is over 0.001 then add a 1, if not leave blank. Then have something like if the column has a 1 in it then check the next, if this one has a 1 in it then repeat this step, if not then this is 1 spill. Store the amount it starts and stops to a variable and just use that number as the Number of descrite spills.
Would this work?
Thanks,
Marley.

Is there any way that I can import a text file and split the data into three columns without having to go through 65000 lines of text.
It is basically a print off of a directory structure. I have a very large text file that lists the files in folders for each of hundreds of users. I need to divide the information up into three columns so that the below data:

2003-07-15 12:10 PM 1,474,564 blue.mp3
2003-07-15 12:09 PM 858,204 orange.mp3
2003-07-15 12:10 PM 1,665,028 yellow.mp3

BOBfiles
2005-08-23 03:01 PM 917,504 writing.doc
ends up looking like this:
BOBsongs1,474,564 blue.mp3
BOBsongs858,204 orange.mp3
BOBsongs1,665,028 yellow.mp3
BOBsongshappy 917,504 jolly.mp3
BOBsongshappy 331,005 joker.mp3
BOBfiles917,504 writing.doc
I easily imported the file into Excel, but it is still all in a column. Any advice would be appreciated.

Poor old Access. I think I've made it wave a white flag, but based on the following expression I am trying to get it to evaluate, I'm not too surprised...
The situation is that I have a large number of tick boxes on a form, which nicely filter through to a series of fields in a table whose values are either -1 or 0 (according to if the box is ticked or not). Unfortunately, I now need to generate a small piece of text for a report based on which boxes have been ticked. Deep breath...
institution:
IIf([people].[memctf]=-1,"CTF",(
IIf([people].[memwt]=-1,"Westcott",(
Iif([people].[memwy]=-1,"Wesley",(
Iif([people].[memry]=-1,"Ridley",(
Iif([people].[memwm]=-1,"Westminster",(
Iif([people].[memiocs]=-1,"IOCS",(
Iif([people].[memermc]=-1,"ERMC",(
Iif([people].[memmbi]=-1,"Margaret Beaufort Institute",(
Iif([people].[memcjcr]=-1,"CJCR",(
Iif([people].[memcym]=-1,"CYM",(
Iif([people].[memindepba]=-1,"Independent BA",(
Iif([people].[memhmc]=-1,"Henry Martyn Centre",(
Iif([people].[memregchelm]=-1,"Regional (Chelmsford)",(
Iif([people].[memregnor]=-1,"Regional (Norwich)",(
Iif([people].[memregpboro]=-1,"Regional (Chelmsford)",(
Iif([people].[memregalbans]=-1,"Regional (St Albans)",(
Iif([people].[memdiocedsips]=-1, "Diocesan (Eds and Ips)",(
Iif([people].[memdiocnorwich]=-1, "Diocesan (Norwich)",(
Iif([people].[memreg]=-1, "Regional", "Unknown"
)))))))))))))))))))))))))))))))))))))
The logic seemed to work nicely when there were just 3 options in the list, but when I try to enter the above, Access says "the expression you entered is too complex". Poor baby! :D
Does any one have any idea how I can get it to evaluate the data I need?

Hi everyone. I was wondering if anyone could help me. I am in the process of designing a database (Access 2002, office xp), but the problem I am having is that when I am pulling in an ID number, from one form into another form, the form I want this number to land in crashes, with the warning that more than one user is trying to access the form at the same time (they are not, just me).
After having to clear this error box (a few times, it keeps reapearing) errors then appear in each of the destination forms fields. :eek:
I think it is something to do with the way the database is setup in multiuser envirionments and retry intervals etc - and I have been playing about with the values, which seems to work once, but then it goes straight back to crashing. :confused:
If anybody give me some default values that might work :o or any other remedies for this problem, this help would be very much appreciated :)
Many Many thanks.

Many will look at this and laugh but its real.
My Access Dbs are opened in hidden state and i dont see my forms.
This must be the cause.
I tried to hide the menubars using ghudsons code,i disabled the shift key. But i dont know what has happened.
I can nolonger view them. I have tried every method out and i think the only option is to repair OS, may be it will work.
I have enabled the database which i disabled the shift key but when i hold down the shift key, it loads but the forms are totally hidden, STRANGE! ijust see the grey access background and when i click on it twice from the task bar.It pops up.
I have tried to make another database, use the autoexec macro to call a form which enables all command bars, but this works only for this database and when i press the shift key down, this database hides the toolbars and i only see the grey access background. This is happening on EVERY DB ive developed on this machine. I thought it was the access that is totally corrupted but i tried to reinstall my office and i still get the same results
This is now a NIGHTMARE to me.
When db is shifted to another machine it works fine as before.
This is REAL but can i get some suggestions from you folks before i repair my OS.

Greetings,
I'm using flash mx and MDM zinc which i assume connects using the JET rather than ADO database engine.
For the life of me cannot get a simple update to work due to the dates
involved, lost count how many hours have gone by trying!!!
Within access I can easily switch quotes and hash symbols and all SQL THREE SQL queries work without problems on my database i.e.
UPDATE UserOverallResults
SET Results = 20
WHERE UserName ='Robbie'
AND Quizdate= '19/2/2008 12:15'
UPDATE UserOverallResults
SET Results = 20
WHERE UserName ='Robbie'
AND Quizdate= "19/2/2008 12:15"
UPDATE UserOverallResults
SET Results = 20
WHERE UserName ='Robbie'
AND Quizdate= #19/2/2008 12:15#
Within the database the fields are defined as :-
Results (Integer) Username (Text) and QuizDate (Date/Time) within MS ACCESS DB schema.
in Flash MX TextDate param is a STRING and All parmaters are populated appropriately (see this later in error message).
Example of existing date data stored in database in format "19/02/2008
16:48:11" as a DATE/TIME field.
My code within in flash is :-
mdm.Database.MSAccess.runQuery("UPDATE UserOverallResults SET Results = " +
UserScore + " WHERE UserName = '"+ UserName +"' AND QuizDate = '" +textDate
+ "' ");
I've tried with and without Hashes still no joy ..
mdm.Database.MSAccess.runQuery("UPDATE UserOverallResults SET Results = " +
UserScore + " WHERE UserName = '"+ UserName +"' AND QuizDate = Format( '"+
textDate +"', "#yyyy\-mm\-dd hh:nn:ss#")");
The error message I get from the code above is ..
SQL Query has failed for the following reason: Data type mismatch in
criteria expression SQL statement: UPDATE UserResultsOverall SET Results =
30 WHERE UserName = 'd' AND QuizDate = Format('19/2/2008 19:4:35'
,"#yyyy-mm-dd hhnss#")
My text string removes the leading zeros not sure if that would cause an
issue or not (its doesnt in MS ACCESS running query) ...
Anyone have any ideas??? Losing my mind here !!
PS I had problems using '&' instead of '+' to concatenate fields.
Cheers
Rob

Hey All,
Im using MS Visual Web Developer with an Access Database, i am trying to enter a new row of data into a database via a select statment attached to a button_click event. the code i am using looks something like this.
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.AccessDataSource2.SelectCommand = "INSERT INTO [Tblissues] ([IssueDate], [IssueTime], [PlantLocation], [MachineName]) VALUES ('12/9/06', '3:00 PM', 'Gville', 'Snack2')"
End Sub
that being said. when i click the button, NOTHING happens, no error and no insert!!!
I did test the connection to the Database and its fine, i can do an update and i can read the data that exists in the database i just cant insert a new row.
This is not the first time i have delt with INSERT statments but this has me at my whits end and any help would be great.
Thanks

Hi
I have created a monster I think and I am not sure how or why.
I needed a query to tie together data from a range of tables and so it has about 20 constituent queries, each of which involves some calculation.
The query isn't so horrendous
SELECT tblApplications.lngApp, qryExpWkHomeHelp.WkHomeHelp, qryExpWkPrescrip.WkPrescrip, qryExpWkHosp.WkHosp, qryExpWkRent.WkRent, qryExpWkSup.WkSup, qryExpWkInt.WkInt, qryExpWkLife.WkLife, qryExpWkCouncil.WkCouncil, qryExpWkCar.WkCar, qryExpWkCar1.WkCar1, qryExpWkHp.WkHp, qryExpWkDep.WkDep, qryExpWkCont.WkCont, qryExpWkProp.WkProp, qryExpWkOther.WkOther, qryExpWkTel.WkTel, qryExpWkTv.WkTv, qryExpWkWater.WkWater, tblApplications.lngAppCon, tblApplications.bAppEleg, tblApplications.dtmAppGcSub
FROM qryExpWkWater RIGHT JOIN (qryExpWkTv RIGHT JOIN (qryExpWkTel RIGHT JOIN (qryExpWkOther RIGHT JOIN (qryExpWkProp RIGHT JOIN (qryExpWkInt RIGHT JOIN (qryExpWkLife RIGHT JOIN (qryExpWkCouncil RIGHT JOIN (qryExpWkHp RIGHT JOIN (qryExpWkDep RIGHT JOIN (qryExpWkCont RIGHT JOIN (qryExpWkCar1 RIGHT JOIN (qryExpWkCar RIGHT JOIN (qryExpWkSup RIGHT JOIN (qryExpWkRent RIGHT JOIN (qryExpWkPrescrip RIGHT JOIN (qryExpWkHosp RIGHT JOIN (qryExpWkHomeHelp RIGHT JOIN tblApplications ON qryExpWkHomeHelp.lngExpApp = tblApplications.lngApp) ON qryExpWkHosp.lngExpApp = tblApplications.lngApp) ON qryExpWkPrescrip.lngExpApp = tblApplications.lngApp) ON qryExpWkRent.lngExpApp = tblApplications.lngApp) ON qryExpWkSup.lngExpApp = tblApplications.lngApp) ON qryExpWkCar.lngExpApp = tblApplications.lngApp) ON qryExpWkCar1.lngExpApp = tblApplications.lngApp) ON qryExpWkCont.lngExpApp = tblApplications.lngApp) ON qryExpWkDep.lngExpApp = tblApplications.lngApp) ON qryExpWkHp.lngExpApp = tblApplications.lngApp) ON qryExpWkCouncil.lngExpApp = tblApplications.lngApp) ON qryExpWkLife.lngExpApp = tblApplications.lngApp) ON qryExpWkInt.lngExpApp = tblApplications.lngApp) ON qryExpWkProp.lngExpApp = tblApplications.lngApp) ON qryExpWkOther.lngExpApp = tblApplications.lngApp) ON qryExpWkTel.lngExpApp = tblApplications.lngApp) ON qryExpWkTv.lngExpApp = tblApplications.lngApp) ON qryExpWkWater.lngExpApp = tblApplications.lngApp
WHERE (((tblApplications.bAppEleg)=Yes) AND ((tblApplications.dtmAppGcSub) Is Null));
Well maybe it is pretty horrific!
However it is taking nearly two minutes to load on a fast PC (3.4GHz Pentium 4 with 1Gb RAM) so put it on a basic desktop and it will die.
I did wonder about fragmenting it into four queries and then putting one query at the top of the nest but reckon that's another layer and all the calculations need to be done.
Basically the sub queries are calculating a weekly value based upon input and periodicity of payments - i.e. if quarterly then it divides the payment by 13.
Any thoughts on how I could speed it up?
Thanks in anticipation

Hi,
I have been using "fSetAccessWindow (SW_HIDDEN)" in the open event of my
main switchboard to hide the grey Access screen from being visible behind
forms, reports, etc in this db. But when I started using a .vbs script file
to launch the db, the Access window stopped being hidden. (The reason I use
the script for launching is that it temporarily sets the db's security level
to 1 which stops the macro security warning from coming up.) Apparently MS
knows about this happening and released a technique to rectify the situation,
but I don't understand their instructions. It looks like they expect one to
have more understanding than I have. Could someone help me get this
impliemented? Here is the article:

Using Access's User and Group Accounts or Using a Login Form to access database?
I've been researching on how to make a database secure. How to create User and Group Accounts on access, I see the step by step instructions and tried it out myself.
I also saw some sites where they give an example of a Login Form and how to create one.
My question is do you need to create both. First create the users and groups to permit or deny access to certain forms and then have a login form?
But would that mean that they'd have to login twice? Once when the database opens because it activates the db security that was created and then login again in the login form that was created?
Also when the user logins in and clicks on the cmd button on the form which opens up another from, frmWorkLog, I have an Employee field. This field I want it to have the user's name entered automatically and "locked". So that info, employee name, is extracted from the user's login. So then the user can only see his or her records only and no one elses.
How would I go about creating that. Hope I made my explanation clear.
Thanks in advance.

I have two database applications and they are:
- the (A) application is for administration use.
- the (B) application is for normal users use.
the idea is that: I made the (A) application for administrators who have full control over the database objects (tables, forms, queries, and so on ...).
the (B) application I have created for normal users who will have only to use forms to insert some data and display data only.
but the two applications has a respective table called "vacation request" table. where I linked them, so the both administrators and users can share the data.
The real question is that: How can I prevent the users from seeing the database objects in their application. I used the database options which have helped me in hidding the database objectives when the users open the application, but unfortunately they managed to access to the database objects by pressing the special keys.
I would like to have an access to the (B) application when I want to make some modifications to the forms and then lock it from users where they only have to use the forms for requesting vacations and view the vacations.

I have a simple access search form , that's based on a query that fill parameters from the form textboxes, when the access form loads its keeps prompting for parameters value which looks ugly .. I want to open the form, displaying all the records in the table and filter when i click search ..
I have a data entry entry form, that i want to generate success message after successful insert in database. I have done it in the button event if no error happens, still if i left all fields blank and clicked save, it displays the message ..
I need to change that to display please fill the textboxes then click save , and display success message when the row is actually inserted ..
Check the following attachment for sample.

I've been using the following code successfully in Access 2003 & now I need to migrate to Access 2010. The purpose of the code is to use the items that the user selects in the list box to build the criteria of a query. Access 2010 keeps giving me a syntax error when I try to run the query & I don't know why:
My code is:
On Error GoTo Err_Command151_Click
' Declare variables
Dim db As DAO.Database
Dim qdf As DAO.QueryDef
Dim varItem As Variant
Dim strCriteria As String
Dim strSQL As String
[Code] .....
The syntax error I get in Access 2010 is:
Syntax Error in query expression 'SELECT * FROM
qryContractListSummarybyDateContract3TYPEBREAK WHERE
qryContractListSummarybyDateContract3TYPEBREAK.Rep ortableName IN('Adbri

Attached is a screenshot of the relationships in a database I built a couple of years ago. It's worked absolutely fine in Access 2003 and currently has over 18,000 customers with associated information in it.
However, when I open the database in Access 2007 the performance is awful. All the forms are very slow to respond when tabbing between form elements. I've experimented by reducing the number of form elements calling on related data on a given page and whilst this improves performance it reduces usability - something I don't want to compromise on especially since Access 2007 should be able to cope with this.
My next question is therefore whether I've got the most efficient underlying table design and I can't see any other way of doing it than my current method so I'd be grateful for any feedback or advice anyone has.

I have a stock control database which i have nearly completed. This has Manufacturer, which is linked to products, which is linked to Sub Product(which also has field partCode). i.e. Manufacturer1 can have 3 products, and each of these products could have 5 subsystems and partcodes. Each partcode is unique to that subsystem/product/manufacturer.
I then have a pricing spreadsheet in excel, which has many tabs. A new column has been added for each item for Manufacturer,Product,Subsystem and Partcode.
I need to import these manufacturers,products,subsystems and partcodes, but into the tables with the correct relationships, i.e. product1 and product2 are products of manufacturer1 and so cannot come under manufacturer2, and so on.
I hope this makes sense, Thanks in advance for any help you can give!

I am working on a massave aplication that has been running in Access 2000, but recently several of the file sharing users have installed Access 2003 because of the limited availability of Access 2000. All the users are using the same file off the server.
The problem we are having is that when we reference a subform in the "[Forms]![FormName]![SubformName]![FeildName]" Access 2003 does not recognize it and returns an error. I have found that if I will modify it to "[Forms]![FormName]![SubformName].[Form]![FeildName]" it is recognized in both 2000 and 2003.
To try and change every instance of a subform reference will take forever and I am garuteed to overlook something. We reference subforms all over our program, missing any one of them would be a disaster. Before I went to the tedious task of looking through everything I just wanted to throw the situation out there and see if any of you had any great ideas on how to get it fixed efficiently. I would apreciate any ideas.

I have made a form on access which will be used by other employees within the company, however they have never used access before and they are wanting to access only just the form as I feel with Access and all the tools in the background will confuse them, plus I don't want them editing the data base its self.
Is there a way to only bring up the form, unless I obviously need to edit the date base.
I've done some research on Google and it seems I need to use:
SW_SHOWMINNOACTIVE
However I can not seem to find how I would use this or where?
and also if i did find a way to only bring up the form, how would I be able to switch it from that veiw to the veiw I edit in?

I have an Access DB that I created in Access XP. It works perfectly when used in Access XP. When used in an Access 2003 environment some of the functions don't work anymore. I have users who use Office XP and users who use Office 2003. Does anybody know how to make this DB work in Access 2003 without having to do wholesale code changes?
I have already changed the security to "Low" to bypass the security feature built in in Jet 4.0 but it didn't help. I might have to uninstall Windows XP SP2 to make it work because I know that the application works in an Office 2003 environment with Windows XP SP1 only. But I'm trying to avoid having to uninstall XP SP2 because it's a pain. Any ideas would be greatly appreciated.
Thank you.
My workstation environment is as follows:
OS: Windows XP SP2
Office: Office 2003 SP1
Jet: 4.0

Hi,
I've created a database in access 2003 with the default file format being Access 2000. Everything works fine on my computer and many others, all of whom are running different versions of access (2000, 2002 & 2003).
I have not had any problems with this database until recently and in the last few weeks we have had 2 users, both of them being Access 2000 users who have had the same problem.
The problem they are having is that when they click on any of the switchboard items, the buttons depress an then come back up again when the cursor is moved away, but nothing else happens - no action, no error message - nothing!!! Its the same for all of the buttons on the switchboard.
Does anyone know what is causing this? I have another computer with Access 2000 on it and this works fine, as it does on several other computers runiing Access 2000, I just cannot understand why it is not working on these 2 particular machine.......
Many thanks in anticpation.

Hello,
I have two questions related to deplying an Access project I have been working on.
1. I started developing the project in Access 2000, but midway upgraded to Office 2003 and so the remainder of the project has been developed in Access 2003. Things seem to be fine, except that in the top most title bar, after the project name, there appears the following text:
xxxxx: Database (Access 2000 file format)
where xxxx is the name of the .mdb file.
Why is this appearing and should I have done something or do something to make it a Access 2003 format?
2. I am at the point of deplying the db to a small group of users (about 5). Some of them may have Access 2000 or Access 2002. Should I be doing something in particular to make sure things work in their machines.
Any pointers to what may be problems or what I should do will be much appreciated.
Thank you.
