I have created a sample MS access 2007 database and designed a form to retrieve the records of the user , if the username and password entered in the form matches the record.In the button action it redirects to visual basic IDE . May i know how to connect to a ms access database from vba by getting the values from the form, and how to execute SQL query from that.
Learn how to work with Recordsets. To execute SQL that will not return any result use:
DoCmd.RunSQL

I am trying to use MS Access to query an MS Access database that is not the current database. I am using:
SELECT [tblA].[fieldA]
FROM [tblA]
IN "G:\path\databaseA" "Microsoft.ACE.OLEDB.12.0;"
WHERE ((([tblA].[fieldA])="30000"));
Running this query returns the error Could not find installable ISAM.
I thought the connect string might not be necessary when connecting to another MS Access database (extension .mdb) so I also tried:
SELECT [tblA].[fieldA]
FROM [tblA]
IN "G:\path\databaseA.mdb"
WHERE ((([tblA].[fieldA])="30000"));
However, this returns the error "The text file specification does not exist. You cannot import, export, or link using the specification."
Does anyone know a way around this?
I have been searching for several hours regarding how to create a user using SQL for a database I am building in Access. I found several sources on Microsoft's website that say I can use the CREATE USER command to do this. However, whenever I attempt to run the query, an error saying Syntax error in CREATE TABLE statement pops up. What am I doing wrong? Thank you in advance for your help! If you're interested, the code format I am attempting to use is as follows: CREATE USER username, password, pid.
Access does support CREATE USER as a DDL statement, but unfortunately it won't work in all contexts. Specifically, it won't work if we try to run it from
the Query Designer within Access itself,
a DAO connection to the database, or
an ODBC connection to the database.
It will only work when run from an OLEDB connection to the database. That can be accomplished from VBA code within the Access database itself by using the CurrentProject.Connection object, like so:
CurrentProject.Connection.Execute _
"CREATE USER newuser newpassword newpid"
(Note that there are no commas between the three arguments to the CREATE USER statement.)
Using Access 2007 with db saved as Access 2003
I have table Table1 with one Field MyDate.
When running a query
SELECT * FROM Table1 WHERE Table1.MyDate < Date()
have an error <Message> in query expression <expression>. (Error 3075)
When using this query in Db saved at 2010 Access, is OK.
Any Ideas?
Update: Using Access 2007 with Access 2003
I've noticed that problem is in the particular database.
Problem was solved when I resaved db. Strange behavour...
I currently have an Access database stored locally. I update this by using Excel as a front-end to input some information and have VBA that inputs records to the database. That is to say, I have a table in Excel that I can add rows to and run a macro that executes some SQL to put it into Access.
I want multiple people to be able to make changes to the Access database, so I have stored it in SharePoint. The problem is that just changing the filepath in my VBA gives me "Operation must use an updateable query" because opening the database is done in read-only mode when you open from SharePoint.
The VBA looks something like this:
Sub Insert()
Set appAccess = CreateObject("Access.Application")
appAccess.OpenCurrentDatabase accDbLocation, True
theSQL = "insert into Table(data)"
appAccess.CurrentDb.Execute theSQL
appAccess.CloseCurrentDatabase
End Sub
Is there any good workaround for this? Perhaps a way to check-out the database from SharePoint, make changes, then check it back in? Failing that, are there other ways to interact with an access db on SharePoint, like making a form that could be used to add records?
Thanks!
How to get the table structure in MS Access with a SQL query?
Using the following query:
SELECT name FROM MSysObjects
Results in the following exception:
Exception: [Microsoft][ODBC Microsoft Access Driver] Record(s) cannot be read; no read permission on 'MSysObjects'.
To resolve the permissions issue for MSysObjects, see these similar questions:
no read permission on 'MSysObjects', or
Run C# queries against (hidden) system tables in Access?
Use This
SELECT * FROM MSysObjects WHERE Type=1 AND Flags=0
Ms Access has several system tables that are, by default, hidden from tables list. You can show them.
In Ms Access 2007 do a right click on tables list and select Navigation Options. At the bottom of the form you will find Show System Objects check box. Check it and system tables will show up in tables list. They all start with MSys.
Alternatively, options form can be activated from application menu - click button Access options -> select Current Database and there is Navigation Options button.
Now you can examine structure and contents and generate queries of all system tables with MsAccess tools.
