Updating MS-Access Database query

hello

i need to update my MS-Access database thru matlab.

when using the following code using function "updates" it updates the
database i.e

.......whereClause = 'where month = ''Nov'''.....

Here "Nov" is an entry in the database.

Now when i assign a variable to the months..ie variable name
"MNTH" could contain Jan /Feb etc,.....and i want to pass the
variable "MNTH" ie

.......whereClause = 'where month = ''MNTH'''.....

it DOES NOT update the database and i receive the error

.....error in horxcat....cannot convert from character to cell
array....

Why am i not being able to pass a variable name which contains the
field name to be updated in the database?

Kindly help
Thanks
Ashish

MATLAB command to access MS Access database
Hi! Is there a MATLAB command which gives access to a .mdb MS Access database or do I need a special driver? Thanks, Andree Hi Andree Ellert, you can use activeXcontrol to interact with MS-Access database. access = actxserver('Access.Application'); returns the handle for Access. set(access, 'Visible', 1); will show the opened Access window. use get(access) and set(access) commands to find the methods available to call. -Vadivelu M =========== http://www.mathworks.com/access/helpdesk/help/toolbox/database/datatool.shtml "Andree Ellert" <ellert@gmx.net/////\\\\\> wrote in message news:eed9874.-1@webx.raydaftYaTP... > Hi! > > Is there a MATLAB command which gives access to a .mdb MS Access > database or do I need a special driver? > > Thanks, > > Andree Andree Ellert wrote: > > > Hi! > > Is there a MATLAB command which gives access to a .mdb MS Access > database or do I need a special driver? > > Thanks, > > Andree <http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=4045&objectType=file> -Hardik ...

Use ASP to read MS Access query that calls MS Access function
Hi: I have an MS Access query for a table called MyTable. One of my fields in the query is a custom field that looks like "MyField: = MyFunction(ID)" where ID is a field in MyTable. I have ASP code and I can use it to read the query OK when "MyField" is not part of the query. If I add in MyField and then run my ASP code to try to read all the query fields, I get an error message on my web browser which says something to the effect of "cannot find MyFunction." On the Access side, I have MyFunction set up in a module and use the keyword "Public" in front of the function name. What else do I need to do to get my ASP code to run this query. I'm trying to avoid reproducing MyFunction within the ASP code if possible. Thanks. Kevin On Thu, 14 Jun 2007 21:38:19 -0000, k-man <kmccrack@gmail.com> wrote: Sorry, no can do.

MS Access, Oracle 9i, security, and pass-thru update queries
Architecture: Access 2003 client, Oracle 9i repository, no Access security in place, ODBC linked tables. 100 or so users, in 3 or 4 groups (Oracle roles actually): Admins, Updaters and ReadOnly. Each group sees a different set of menu options when they open the client and login to Oracle. For the sake of speed I use pass-through queries here and there for updates and deletes. I update their SQL property in code and execute them. Since the pass-thru queries need Admin priveleges, I could/would like to store the Admin password with the query. But that's Security Breach #1, since you can import the query into another .mdb (even from the .mde), and see the Admin password. To get around the breach, I don't store the password with the query, and when Admins login I create a pass-thru query in code, and connect to the db with the Admin password, thus setting their permissions for the session. This works fine, but it's kind of kludgey. I'd like to protect the queries (and ODBC table links) from prying eyes, and I definitely won't be using native Access security. Ideas?

Excel database query does not work after securing an Access database
Hi all, I'd appreciate if someone could give me a hint to this little annoying problem: I have a simple database that I want to be able to query from Excel. When I use the "new database query" wizard on an unsecured version of my database, everything works fine. I am able to read the tables and queries, I can build customized queries in Excel from the Access tables/queries. Now, the moment I secure my database I loose all connectiviity between Excel and Access. The wizard won't even connect to the database. When I add permission to "open/read database" object through "Users and Groups Permission" in Access, I am able to connect to the database and see all the tables/queries, but it does not show the fields. I thought that in theory if I add permissions to "read design" and "read data" to my tables and queries for the regular users that should solve the problem, but it doesn't. I am obviously missing something somewhere, but what? I searched the web but could not find anyting. I am using Windows XP Pro SP2 and Access 2003 and Excel 2003. Any advice???? Michael I'm actually just facing this problem as well myself, and have no answer. I have a secure database that's split front and backend. I've had split secure databases before where I have been able to query via excel, but for some reason, this one won't let me. ...

access MS-Access database in C# Windows Application
Hi, I am trying to access the MS Access database on my local machine in C# Windows Application in Visual Studio.NET. But it seems that it does not work. I use the Microsoft Application Blocks to access the database. I have tried 2 possible connection strings. ----------------------------------------- str_1 = "Driver={Microsoft Access Driver (*.mdb)}; DBQ=" + DBFilePath; str_2 = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + DBFilePath; //SqlHelper is the class in the Microsoft Application Blocks SqlHelper.ExecuteNonQuery( str_1, CommandType.Text, SQL_str); ----------------------------------- The error message I got is: "Unknown connection option in connection string: driver." for str_1 and " Unknown connection option in connection string: provider." for str_2 So I am wondering, where is the problem? Is it because my connection string for MS Access is specified wrongly? Or is it because I cannot use SqlHelper to access the MS Access database? ( I have used SqlHelper class to access the MS SQL server, and it works) Your help will be greatly appreciated.

how to access the queries made and stored in MS Access thru C# Code?
hi, Does anybody know how to access the queries made and stored in MS Access thru C# Code. thanks, bjorn Yes. You will need to use classes in namespaces System.Data System.Data.OleDb A quick example of a function that returns a dataset might be (unchecked) -------------------------------- using System.Data; using System.Data.OleDb; public class MyClass { string strConnect = "enter your OLEDB connection string here"; public static DataSet ExecuteDataset(string strSQL) { try { //create a command and prepare it for execution OleDbConnection objConn = new OleDbConnection(strConnect); OleDbDataAdapter objAdapt = new OleDbDataAdapter(strSQL, objConn); //Fill the dataset DataSet DS = new DataSet(); objAdapt.Fill(DS, "DataTable"); return DS; } catch (Exception ex) { //return nothing if an error has occurred return null; } } } --------------------------------- to use the function, you might do the following: DataSet objDS = myproject.MyClass.ExecuteDataset("SELECT * FROM qryMySavedQuery"); --------------------------------- There's a lot to learn in.NET so I'm not going to try to show you everything here.

Problems with MOD-Function by accessing MS-Access Database via SQL in Delphi
Hello, the following problem: I use Delphi 6 to access a MS Access Database. In short, the Delphi Code looks like this: ADOConnection1.Open; ADOQuery1.Close; ADOQuery1.SQL.Text :=3D 'SELECT * FROM database1 WHERE value1=3D1 AND value2=3D ' + inttostr(array[3]); ADOQuery1.Open; Label5.Caption:=3DADOQuery1.Fiel=ADdByName('value4').AsString; Now I only want to select these rows, where the Integer value3 ends on 1=2E So I need the Modulo-Function. I found in the Internet these two functions: MOD(x,y) und x % y But I get an error if I want to use one. For example, If I change ADOQuery1.SQL.Text :=3D 'SELECT * FROM database1 WHERE value1=3D1 AND value2=3D ' + inttostr(array[3])+' AND MOD(value3,10) =3D 1; Delphi shows me a Syntax Error in this statement. Thx for help! Sorry, there is a ' missing in the code. But it has nothin to do with the problem: The first code runs perfectly, but If I insert AND MOD(20,10) = 0 there is the syntax error again.

MS Access Script to import data from external mde database to mdb database
Hi, Does anyone know of a way I can write a script that imports a table from a particular .mde file? I don't seen any obvious way to do it as a macro. Any suggestions if it can be done as a macro or as a written module? My ultimate goal is to have script that clears info out of 1 table in an .mdb file, imports an identically structured table from a .mde file, runs an append query I have in place to copy the data from the imported table to the table in my.mbd file, and then delete the imported table. Any help that could be provided would be greatly appreciated.

Should I upgrade from MS Access 97 to MS Access 2002
Hi guys My company has in one of their products used Access 97 and MS JET 3.5 for several years now. Should we move the database to Access 2002 -which we use now in other parts of the company and also upgrade the MS JET to the latest version? And what does MS JET do? Kjell Arne Johansen MS Jet is the database engine that comes with, and is, by default, used by Microsoft Access. If you aren't having any troubles with the Access 97 database, then there isn't any technical reason to change. There may be company political reasons if, say, the IT department only wants to have one version of Access in-house. Another reason might be if you were concerned about getting support (error fix support) from Microsoft. Then again, when is the last time you had to call Microsoft support for this database?

MS Access database in IFS
re my earlier question about starting an Access database in the Integrated File System: 1) I cannot use STRPCCMD because the request might be initiated by a dumb screen. 2) I have had no success with RUNRMTCMD 3) Can Qshell be used? I merely need the database running to perform the same function as an evoked RPG program, but the sytem IPLs on a Monday morning so ideally the initiation would be part of the IPL. Many thanks Peter Kinsman On further consideration, because the database is not an executable, I don't think the idea would work, because it would need the path to a copy of MSAccess.exe - which would have to be on a PC.

Peter: 1) Makes sense. 2) Can't comment since you give no indication what problems you've had with it. RUNRMTCMD is essentially the standard way of having one system execute a command on another system across a TCP/IP network. It doesn't matter what the platforms are (though the commands are different under different operating systems). 3) Qshell can be used if you want to use the rexec utility. It's essentially RUNRMTCMD in a Unix-like shell. If you don't like the easy RUNRMTCMD (or rexec) functions, I suppose you could alw...

Opening MS Access database
Hi, The problem is that while opening MS Access database via ADO/Jet4 with connection mode set to adModeShareDenyWrite, this should prevent others from opening in write mode. But it denies writing all (including me)! Adding adModeWrite allows to write but doesn't prevent others from writing... I want to open the database in share mode so that only one user can write while others can read. Is it possible?

Access is not a multi user database application in the first place and sooner or later the database will become corrupted and will have to be repaired. This happens on a routine basis that MS Access databases must be repaired because of multi user usage. You should look into using MS SQL Server, which there is a personal version of SQL Server that will run on a Windows NT based works...
