SQL Or Visual Queries
Oct 18, 2006
I hardly ever use SQL directly - occasionally when I need to update something, and when I need a union query, but generally I try to use stored queries with global functions for parameters, rather than form references.
The SQL examples in this forum look very complex to write, and therefore very easy to miscode.
Assuming that visual queries are available in a particular system, is there any benefit to writing SQL code directly - is it faster?
Thanks in anticipation

I'm doing some debugging over the phone.My friend has Access 2003.What does not work:When he codes the MID function in a query he gets an error like this:"Undefined function 'Mid' in expression."
In the Visual Basic editor, he gets the same error: MID is undefined.What DOES work:I walked him through the use of LEFT and RIGHT in the query and they work.In Excel, MID works.Might there be some odd ball Access configuration mess up, or maybe more likely, his Access installation is incomplete.

Hi,
Many thanks to those who helped with my last couple of problems.
I've allmost completed my project now and am debugging.
I've found that in order to close one of my forms, which has combo boxes on it, I need to have no values selected in those combo boxes. Could someone give me the visual basic script (or any alternative meathod) for resetting the combo boxes to their default values; i.e. nothing selected in them!
Many thanks,
Robin :o

I got a new job (another one, actually) and though it has absolutely nothing to do with databases, or computer work for that matter, I told my boss that I like building database apps with Access. He sparked up and said that he has a program in Visual Fox Pro, an application that's "more powerful" than access, but someone came in way back when and wrote a "program" that did some calculations to the existing DB, but the PC is dying and when it does, will take the addition with it. He said that he'd be interested in me looking into it and hopefully being able to replicate the work the prior person had done.
Has anyone worked with VFP and worked in Access with it? It doesn't seem very flexible at all and it's not very intuitive. I'm not impresses with it at all, but I have an opportunity here with my boss and would like to "get her done" so to speak.
Any help or links to good VFP tutorial sites would be greatly appreciated.
Thanks.

Greetings to all the experts out there,
Here is something I wonder if it has already existed or been asked before, a program or an add-in feature that can compile an Access database (including forms, reports, tables...) to a stand-alone .exe application, just like Visual Basic does. The reason why I think it's doable is because in Access, we use VB codes anyway and it wouldn't need to be rocket-science for Access to do something like that or this would be an improvement for future versions.
There are plenty of advantages of going from an Access form to a stand-alone app, i.e. we wouldn't need codes to hide background and menu or status bar; we wouldn't need to disable mouse-scroll or prevent users to go back and accidentally delete past records; or we wouldn't need to worry about users seeing your terrific coding techniques and on and on.....Agree that all these can be done within Access but imagine how much time it'd save you from not doing all these things.
Thank you all in advance.

I have a user running office 2007, with a program called Dev_Tracker wthat uses a front end of access 2000. This program allows a user to log in their project hours. The skinny is that when they lauch the program and try to make an entry they receive this error message:
Run-time error 3075
syntax error in date in query expression tbl_timesheet.weekof=#2.4.2008# AND tbl_timesheet.user=dworden.
If the user logs into another machine it works fine so it appeare to local to the machine. I have cleaned the registry and done other tweaks but no luck.:confused: Any ideas would be helpful.

I'M NEW TO DATABASE PROGRAMMING AND HAVE LIMITED PROGRAMMING EXPERIENCE. SIMPLE EXPLANATIONS AND TERMINOLOGY ONLY PLEASE
I've been tasked with producing two database systems at work.
1) A job ledger (currently excel)
2) A stock condition survey database
Question
For future proofing:
* what coding should I be investigating (I expected to use Visual Basic, I understand this has now given way to Visual.NET?)
* Should be upgrading to Access 2007?
* Where the best place for sample databases of this kind?
* What's an SLQ system? Should I be using this instead?
All help appreciated

I searched everywhere, but I think my ignorance of correct terminology is preventing me from finding the answer I need.
I have a form that holds two cascading list boxes. I want to be able to incorporate another list box that holds a record of which selection that was made, and how many per selection. The idea is to give user a visual feedback of what they selected, and be able to modify the selection.
I tried
Let Me.IDSelection.Value = Me.CategoryID.Value And Me.Specifics.Value
but the box stayed blank.... What am I doing wrong?

Okay,
On a form with a subform, when viewed in "Form View" the form and the subform ALWAYS has this vertical bar on the left side with an triangle arrow pointing to the right.
What Is that?
Can I make it go away?

I'm getting the following error when I try and open my database: "The visual basic for applications project in the database is corrupt". I'm pretty sure I know the answer, restore from a back up. The only problem is that the sytem admin usually backs the file up every night and he has not gotten a valid backup for the past week. If any one has any ideas, besides restore, please let me know. You would save me a lot of extra work.

There is an online form which we need to fill out for each of our inventory units. This form has several dozen fields though. We have to fill each one out for every unit that we ship (which is about a hundred a day).
But the good news is, about 25 of these 30 fields are always filled in with the same value (our name, address, city, state, zip, insurance, insurance no, carrier, carrier no, etc).
What we want is a way to fill out these fields for us automatically, and all we have to do is type in the remaining 5 fields ourselves.
My temporary solution was to create a form with 5 fields and a Submit button. Then using AppActivate "Inventory Adjustment - Microsoft Internet Explorer", we would use the SendKeys function and virtually "type" in the 5 variable values and the 25 other "hardcoded" values, using the Tab key to move in between fields.
However, we have encountered some issues using SendKeys. For one, the cursor doesn't always start in the correct place, and the fields become horribly offset and skewed. Also we notice that sometimes the cursor moves "too fast" apparently and skips pasting some of the values (an issue we tried to resolve by using "wait" commands, but it didn't help consistently enough).
Is there a better way to use Visual Basic to fill in fields in an Internet Explorer window? :(

Hi all,
Has anyone experienced this problem?
Ver: MS Access 2002 (10.6501.6735) SP3
MS Access / MS Visual Basic will not step through the code after I set breakpoints for debug.
This has always worked but recently it has stopped?
Anyone have any ideas? maybe a hotkey to toggle debug on/off?
Thanks

Hi guys,
I have basic knowledge of microsoft Access and do very little with script and coding. I also design websites and can code in HTML and have good skills in Dreamweaver etc.
If I want to create a database driven website is Visual Web Developer 2005 a good software choice??
The way I see it the software will allow me to use my design skills and database knowledge to create the data driven website without needing alot of knowledge about MYSQL and PHP etc.
Thanks
James

I have an access Query(named newSerial) :
SELECT TOP 1 (Productbase.Serialnumber+1) AS Expr1 FROM ProductBase
ORDER BY (Productbase.Serialnumber+1) DESC;
I want to access this new value. Its not a key since an autonumber may be any number. When I create a new product. How do I get this value inside a form?
It works fine when clicking on it. But if I use an unbound box I get 1 as result and not like 76067 which it should be. If I click the query in access it works fine and show 76067.
I tried:
outbox=Expr1
' gives null
'or
outbox=[newserial].[Expr1]
' which gives "Access cant find the field "|" refered to you in your expression"
What should I write? Whats the correct expression?

I am in the process of re-writing an Access system that was created with 100% macros. I need to convert the custom menus that were created with macros to vb code. I tried to convert the code to modules, but I can tell that is not the path. Does anyone have a simple example? For instance, the first custom menu is just File, Exit.
Thanks in advance.

Hello,
I am hoping someone might be able to help me out. I am trying to create a delete query in VB for access.
I have managed to get it to run the delete query, but I would like to program in the responses to the following questions:
"You are about to run a delete query that will modify data in your table. Are you sure.... Yes"
"You are about to delete X row(s) from the specified table. Yes"
Here is what I have so far:
Private Sub Command32_Click()
DoCmd.OpenQuery "DELETEQUERY", acViewNormal, acEdit
End Sub
Does anyone know how to do this???
Thanks,
Jason

Trying hard to create new database. After editing VB code error message appears
"error accessing file, network connection may have been lost" tables and forms are set
in one file. This has occured numerous times. If I had hair I would be pulling it out .
It seems to lose the code for a form. If you delete the form it remains in the Project Browser.
There seems to be a "remove icon" but it is deactivated.
Any ideas...Im desperately running short of time, any help will be gratefully accepted

Have you guys ever used this scheduling tool from FMS Software that will do a nightly archive and compact/repair.
I tried it out on our live database (not so smart I guess) on a Friday and when I came in Monay it was corrupted. It seems to point to the FMS software corrupting my db.
I wanted to validate and use this software but ain't sure it I will now.
I like the nightly compact/repair. Is there another way to do that with Windows Scheduling or something?
Take a look:

I want an append query to add records to one of several tables, depending upon the value of a variable entered into a form. This variable is also used to select the appropriate records. The query is invoked from the visual basic code behind the form.
Can anyone tell me how to edit the destination table from within the visual basic?
In hope...

Hi. I have recently made a video database for a project, and have have come to a small problem. What I wanted to do was to, using a query search, find the total number of results found, in a form.
Basically, I have a query, in which I have the Film Name, Movie Cost e.t.c, with - Like ("*" & [Film Name], as the Expression (under Film Name).
When using the query, it retrieves results for what you have typed.
I use the query on a form "Film Search", which when clicked on Automatically brings up the Search Box. I also have another form "Films", which has a "Search Films" command button on it, run from a Macro. So basically everything works fine, but I when I search for a film, I want to have a text box, on the form, which has a count for the results.
For example, if I searched say "Shrek", and I got results for Shrek, Shrek 2 and Shrek 3, the text box would say - " 3 results found".
This brings me to the conclusion of asking if I should do an expression, from the original query I am using, or to use Visual Basic, and more importantly - HOW?!?
Any help would be GREATLY appreciated, and I am sorry in advance if one, I have not explained my problem well enough, and two, this is in the wrong section.
Thanks in advance
Jk

first i must thank everyone here. this forum has proved invaluable for some of the simple databases i have created. now i have a problem which i cannot find the answer for.
i'm using access 2000
basically i am creating a cemetery database so most of the information i'm dealing with is duplicated. to create a unique record i have six primary keys on the one table. ie people with the same name, age, and birthday can be buried in the same grave.
anyway i need to do a wildcard seach from a form (QBF) based on surname and firstname. i have downloaded the code below and modified it:
Private Sub cmdsearch_Click()
'Set the Dimensions of the Module
Dim strSQL As String, strOrder As String, strWhere As String
Dim dbNm As Database
Dim qryDef As querydef
Set dbNm = CurrentDb()
'Constant Select statement for the Query definition
strSQL = "SELECT searchtestdata.Surname; searchtestdata.Firstname; " & " FROM searchtestdata"
strWhere = "WHERE"
strOrder = "ORDER BY searchtestdata.autonumber;"
'Set the WHERE clause for the QueryDef if information has been entered into a field on the form
If Not IsNull(Me.txtsurname) Then '<--If the textbox txtFName contains no data THEN do nothing
strWhere = strWhere & " (searchtestdata.Surname) Like '*" & Me.txtsurname & "*' AND" '<--otherwise, apply the LIKE statment to the QueryDef
End If
If Not IsNull(Me.txtfirstname) Then
strWhere = strWhere & " (Searchtestdata.firstname) Like '*" & Me.txtfirstname & "*' AND"
End If
'Remove the last AND from the SQL statment
strWhere = Mid(strWhere, 1, Len(strWhere) - 5)
'Pass the QueryDef to the query
Set qryDef = dbNm.QueryDefs("quesearchtestdata")
qryDef.SQL = strSQL & " " & strWhere & " " & strOrder
'Open the Query
DoCmd.OpenQuery "quesearchtestdata", acViewNormal
End Sub
the code stops at the line:
qryDef.SQL = strSQL & " " & strWhere & " " & strOrder
and tells me either that i have "run-time error 3142 - characters found at end of SQL statement" - this is the error i am recieving at the moment, or more usually " run-time error 3141 - which tells me the SELECT - WHERE statement is wrong.
i am definetly no expert in VB - i am only just starting using it.
so guys any idea?
thanks in advance
