Catch lock situations accessing database tables

Hi,
are lock situations (two or more reports are trying to modify the same row) catchable by cx_sy_sql_error? Or by any other technique?

Hi Rainer,
Well in case of concurrent updates of same table by different programs, you need to use lock objects.
Goto SE11 & create a lock object if its not already available.
2 Funciton modules would be created ENQUEUE_* & DEQUEUE_*
Use it in both the programs. ENQUEUE_* is used to lock the record & DEQUEUE is to unlock the record.
CALL FUNCTION 'ENQUEUE_MARA'
ExPORTING
MATNR = itab-matnr
EXCEPTIONS
IF sy-subrc <> 0.
message 'Record cannot be locked !' type 'E'.
else.
UPDATE/INSERT TABLE ....
CALL FUNCTION 'DEQUEUE_MARA'
endif.
Pls. ensure that you pass the primary keys to the FM so that locking is done at record level & not at table level !
Best regards,
Prashant

Unable to update or insert into Access database table using OleDB, and it doesn't return any errors.

I'm new to VS. I have run the following code. It does not produce any error, and it does not add or update data to my Access database table.
dbUpdate("UPDATE prgSettings SET varValue='test' WHERE varSetting='test'")
Function dbUpdate(ByVal _SQLupdate As String) As String
        Dim OleConn As New OleDbConnection(My.Settings.DatabaseConnectionString.ToString)

        MsgBox(returnValue)
        Return returnValue
End Function
Any suggestions will be appreciated.
Thanks.

You code looks pretty good, at a quick glance. Maybe you can simplify things a bit.
For Insert, please see these samples.
http://www.java2s.com/Code/CSharp/Database-ADO.net/Insert.htm
For Update, please see these samples.
http://www.java2s.com/Code/CSharp/Database-ADO.net/Update.htm
Knowledge is the only thing that I can give you, and still retain, and we are both better off for it.
Best to keep samples here to VB.NET
Please remember to mark the replies as answers if they help and unmark them if they provide no help, this will help others who are looking for solutions to the same or similar problem.

Join multi access database tables

Anybody knows how to join multi Access database tables
by using LAbview SQL tool kit? It seems Labview SQL does not support "JOIN" feature.
Thanks

But I still dont know how to join multiple tables.
I've tried:
SELECT pd.NAME, pp.PART_ID, pp.MATERIAL, pt.NAME
FROM PRODUCT pd INNER JOIN LOOKUP_PRODUCTPART pp
   ON pd.PRODUCT_ID=pp.PRODUCT_ID INNER JOIN PART pt
   ON pp.PART_ID=pt.PART_ID
But it doesn't work.
Hm.. the following (joinig two tables) works. It's shows that INNER JOIN works in LabVIEW:
SELECT pd.NAME, pp.PART_ID, pp.MATERIAL, pt.NAME
FROM PRODUCT pd INNER JOIN LOOKUP_PRODUCTPART pp
   ON pd.PRODUCT_ID=pp.PRODUCT_ID

Linking Java to Access Database tables

Hello,
I need use JCreator to link Java to Access Database tables.
Could any one tell me what kind of drivers I need use?
Also, where could I find the examples of linking Java to Access Database tables?
Thank you,
Daniel

Thanks.
I have read the tutorial and downloaded the sample code from the web http://java.sun.com/docs/books/tutorial/jdbc/
In the CreateCoffee.java programming, I made the following changes:
     //     String url = "jdbc:mySubprotocol:myDataSource";
          String url = "jdbc:odbc:DB1";
DB1 is an Access Database file located in the same folder as CreateCoffee.java.
//Class.forName("myDriver.ClassName");
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Every time when I run the CreateCoffee.java programming, it shows the following running error:
SQLException:[Microsoft][ODBC Driver Manager]
Data source name not found and no default driver specified.
Could any one have any suggestions for solving the above problem?
Thank you,
Daniel

How to automate creation of MS Access databases/tables/records

Can someone point me to some examples that automate the creation of MSAccess database files and tables?
Can I do this with a bat file? If not, a ps1 file?
I bing searched and could not find an example.
I want to test the existence of a mdb (or accdb) file and if it does not exist, create it.
Then I want to see if that mdb (or accdb) file contains a table named "parts".
If it does not contain that table named "parts", create the table.
If that table does not contain any records, than add some sample data, presumably with some SQL "INSERT" statements.
What is the preferred API for this? I was thinking we should use the ADO.NET/OleDB API. I did find a few examples of queries of MSAccess databases with the old ADO API.
ADOX seems very old for creating databases. Is there any thing more modern?
Is powershell the easiest scripting language to do this?
Thanks

This blog post should have most (if not all) of what you need:
http://blogs.technet.com/b/heyscriptingguy/archive/2009/02/16/how-can-i-use-windows-powershell-to-create-an-office-access-database.aspx
One thing to watch out for is the db provider for the connection string. The "Jet Engine" has been superseded by
ACE.

Deleting a MS Access database table record using JOptionPane

hi!
just want some help here..
is there a way to delete a MS Access database record through using JOptionPane?? i've gone through some, probably alot of examples on SELECT, INSERT, UPDATE, DELETE statements but none came up to the stuff i need.
so far i've seen the DELETE statement like this and also this is a common DELETE statement..
statement.executeUpdate("DELETE FROM tableName WHERE fieldName01 = 'blablabla' AND fieldName02 = 'etcetcetc'");like INSERT, there's a coding somewhat like this:
String asd = JOptionPane.showInputDialog(null, "Enter blablabla stuff");
statement.executeUpdate("INSERT INTO whatEverTableName (tableFieldName) VALUES('"+asd.getText()+"')");so, is it possible using the same method for DELETE??
help and advices are appreciated in advanced..

Here's how I did it. Research does help, but sometimes looking at others code does too... You do have to have a dummy file that you made with access though. You can't just make a file file.mdb (it will be corrupt)
     public void createDatabase(String database) throws SQLException{
          try{
               // This file needs to have been created with MS Access
               File dbfile = new File(this.dataBaseDir + "dummy.mdb");
               // This is the new database file being made
               File newFile = new File(this.dataBaseDir + database + ".mdb");
               // Copy all bytes from dummy file to new DB file.
               FileInputStream instream = new FileInputStream(dbfile);
               FileOutputStream ostream = new FileOutputStream(newFile);
               int numBytes = instream.available();
               byte inBytes[] = new byte[numBytes];
               instream.read(inBytes, 0, numBytes);
               ostream.write(inBytes, 0, numBytes);
          catch(FileNotFoundException e) { e.printStackTrace();}
          catch(IOException e) { e.printStackTrace();}
          if(DEBUG) System.out.println("creating the " + database + " database");
     }

How to store the data captured from oscilloscope into the MS Access database table

Hi All,
In my application, I tried to save the data captured from SCOPE, but could store only 200 bytes. I've taken the Memo data type for the field in database. I want to store all data ( 4 channels) in one field & retrieve back and display on the XY Graph.
Thanks in advance.

Need information on accessing database tables in small incremental chunks

I've been building up a database of information for sometime now. I want to start moving some of the information from the database into other formats.
The table is quite large and I want to use cached row sets with it rather than hold the connection to the database. So I want to learn what the best way would be to grab, for instance, the first 50 items in a cached row set, once they're complete, move onto the next 50 and so on.
However I am fairly new at using Java to interact with databases. I'm not sure what the best way to go about this would be or if I'm even going down the right path by using cached row sets.
Could anyone recommend some decent sites for achieving this or even good web sites for general database manipulation with Java?

Could anyone recommend some decent sites for achieving this or even good web sites for general database manipulation with Java?I am working on a data mining project and I have been dealing with storing large data sets in to a data model, and then arrange those data sets in different formats. If you can live without the cached row set, I would recommend define methods of ResultsSet type and use that to retrieve data from the database and store it in csv file. In my data mining project I was dealing with 3.5+million large data set, chomp them into different chunks of data sets.
Since you have mention that you want to import these data into other formats, I would recommend this option since CSV files can be used in any kind of software applications with out minimum effort.
I am currently hosting the project on Google Code so let me know if you like to take a look at it.

Writing a table to a MS Access database from Powershell

Hey guys, me again...I'm trying to wrap up a project here and i have a powershell app writing to a SQL database just fine. The last piece is writing to a MS Access database table. For the life of me i cannot find anything out there that really points me
in the right direction.
I know my database name/path and i know the table/headers i need to write my data too.
Anyone have a link to a quick dirty tutorial or can someone point me in the right direction ?
Thanks as always

I get no error message. I created a blank database with a table called dbo_so_shprimg_pvs and headers
called so_hdr_key, so_ship_key, imgfileName, so_shprimg_crtdt. I'm doing a test write-host
prior so i know my variables are good.

Regarding File to JDBC/MS Access database

Hi all,
I am trying to insert some values in to MS access database table.I kept the .mdb file in the local PI folder.I am getting connection error
com.sap.aii.af.service.util.concurrent.ResourcePoolException: Unable to create new pooled resource: DriverManagerException: Cannot establish connection to URL 'jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=//test/data/input/Employee.mbd': SAPClassNotFoundException: jdbc.odbc.JdbcOdbcDriver
i have given the configuration as:
JDBC Driver: jdbc.odbc.JdbcOdbcDriver
Connection: jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=//test/data/input/Employee.mbd
Please give me some pointers.
Regards,
Anika

Hi Anika,
Also please check for :
You can set the configuration as following:-
JDBC Driver : sun.jdbc.odbc.JdbcOdbcDriver
Connection : jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ= Full Path of DB file;
eg of full path:D:\USERS\Employee\employee.mdb
Please go through these steps: (Assuming you are working on Windows)
1) An ODBC driver for your database must be installed on the Windows computer running the application server.
Check if there's an ODBC driver for MS Acess on the application Server.
2) To connect through an ODBC driver, you must install the Sun JDBC-ODBC Bridge driver on the Windows computer running the application server. The driver comes with the Sun Java 2 SDK, Standard Edition, for Windows.
Also there is another point.
sun.jdbc.odbc.JdbcOdbcDriver
This driver is a part of the JDK kit and so, you need not install the driver on your XI server. Check the SAP Note JDBC FAQ for this info.
3)Define a DSN on the Windows system hosting your application server.
4)These parameters you need to give while configuring the JDBC receiver adapter channel

Access ABAP table in Webdynpro Java application

Hi All
Is it possible to access ABAP table in Webdynpro Java application
Please provide your input
Thanks
Karthi D.

Hi you will connect to the remote SAP system, the
backend, using an Adaptive RFC MOdel. To access database tables, you can make use of existing functions in terms of RFC function modules. For each function module you need, the system generates a corresponding Java proxy class. All the generated proxy classes and interface are bundled together in the RFC model and treated as part
of your Web Dynpro project
In WebDynpro java you RFC by using Model :
Adaptive RFC Model
1. automatically adapts to changes in function module signature
2 provides support for data types and extensibility
3.support for different structure definitions in different backend
systems (release dependent structures, custom adaptation)
Basic principles and guidelines

Transferring a lot of data from Access Database to Labview

I need to transfer 500000 -> 1000000 values in a Access database table to Labview. The values are selected using a query which is very fast if run in Access itself, but from Labview it's very slow. Obviously the connection between Labview and Access is the slow point.
Im using the NI Database connectivity toolset and a UDL file defines the connection. Microsoft Jet 4.0 OLE DB Provider is used.
To be honest i dont know what that really means, just that it normally works but now its stupidly slow for so much data.
Thanks for any help.

One of my continual gripes with the DBCT is it's poor behavior on large data sets. See NI's response here:

Actually, I wouldn't find it nearly so annoying but for the part that says "In most database books you are told not to return large recordsets...". I prefer the freedom to make a mess of things myself, thanks.
On the plus side, the VI referenced in the article is fairly efficient, you just have to deal with type conversion once things have been moved into LabVIEW.
