Pl/sql block reading reading table data from single point in time
I am trying to figure out whether several cursors within a PL/SQL block are executed from within a Single Point In Time, and thus do not see any updates to tables made by other processes or procedures running at the same time.
The reason I am asking is since I have a block of code making some data extraction, with some initial Sanity Checks before the code executes. However, if some other procedure would be modifying the data in between, then the Sanity Check is invalid. So I am basically trying to figure out if there is some read consistency within a PL/SQL, preventing updates from other processes to be seen.
Anyone having an idea?.
BR,

"Transaction-Level Read Consistency
Oracle also offers the option of enforcing transaction-level read consistency. When a transaction runs in serializable mode, all data accesses reflect the state of the database as of the time the transaction began. *This means that the data seen by all queries within the same transaction is consistent with respect to a single point in time, except that queries made by a serializable transaction do see changes made by the transaction itself*. Transaction-level read consistency produces repeatable reads and does not expose a query to phantoms."

Hi
how to create a external content type for Read and Update data from two tables in sqlserver using sharepoint designer 2010
i created a bcs service using centraladministration site
i have two tables in sqlserver
1)Employee
-empno
-firstname
-lastname
2)EmpDepartment
-empno
-deptno
-location
i want to just create a list to display employee details from two tables
empid firstname deptno location
and same time update in two tables
adilWhen I try to create an external content type based on a view (AdventureWorks2012.vSalesPerson) - I can display the data in an external list. When I attempt to edit it, I get an error:
External List fails when attached to a SQL view
Sorry, something went wrong
Failed to update a list item for this external list based on the Entity (External Content Type) 'SalesForce' in EntityNamespace 'http://xxxxxxxx'. Details: The query against the database caused an error.
I can edit the view in SQL Manager, so it seems strange that it fails.
Any advice would be greatly GREATLY appreciated.
Thanks,

I've got the labview vi written to read my IMU data from a serial port in COM1 and it displays onto the table on the front panel. I'm having trouble getting this data onto an excel spreadsheet. Any ideas? Right now my data will collect one reading instead of continuously reading my IMU which displays data in a continuous stream.
Thanks

How to read a byte data from maxdb data base
Dear All,
I have a issue in reading the data from database table.
I have a column named as templateData which contains the byte data (biometric template data, which comes from fingerprint device) which is DataType of LONG and CODE of BYTE.
I am not using the below to get the template data
Connection con = null;
Statement stmt = null;
ResultSet resultSet = null;
byte[] DbBioData = new byte[1024];
InitialContext ctx = new InitialContext();
if(ctx == null)
throw new Exception("Boom - No Context");
DataSource ds = (DataSource)ctx.lookup(db_drvstr);
con = ds.getConnection();
stmt = con.createStatement();
resultSet = stmt.executeQuery(db_query + " where SUBJECT_ID='"+ username +"'");
if(resultSet.next())
DbBioData = resultSet.getBytes(1);
_loc.infoT("verify", "verify::Got BioData From MAXDB" +DbBioData );
loc.infoT("verify", "verify::Query is: " +dbquery + " where SUBJECT_ID='"+ username +"'" );
But I am not getting the proper data, could anyone please tell me the way to read the biometric data from data base table.Hi Kishore,
is it me or is there no query definition in that code?
I see that you concatenate a "db_query" with a string to make up a WHERE clause, but the db_query is nowhere defined before.
So at least you should provide something like
stmt = con.createStatement("SELECT templateDate FROM <tablename> ");
before you do anything with the query.
Besides this: have you ever heard of SQL injections? Try to use BIND-variables instead of concatenating strings. Otherwise your application will spend much time just with parsing your queries...
Hmm... possibly the best thing you could do about this is to read the JAVA manual for MaxDB:
<a href="http://maxdb.sap.com/currentdoc/ef/2de883d47a3840ac4ebb0b65a599e5/content.htm">Java Manual (SAP Library - Interfaces)</a>
Best regards,

What is the easiest way to export all tables data from Oracle to MS SQL Server?
Hello MS,
I would like to export all tables from Oracle 11.2 to MS SQL Server 2012 R1.
Using the tool "Microsoft SQL Server Migration Assistant v6.0 for Oracle" did not work for me because there are too many warnings and errors regarding the schema creation (MS cannot know it because they are not the schema designer). My idea is
to leave/skip the schema creation to the application designer/supplier and instead concentrate on the Oracle data export and MS SQL data import.
What is the easiest way to export all tables data from Oracle to MS SQL Server quickly?
Is it:
- the „MS SQL Import and Export Data“ Tool
- the “MS SQL Integration Services” Tool
- not Oracle dump *.dmp format because it is a propritery binary format
- flat file *.csv (delimited format)
Thanks!Hi lingodingo,
If you want to directly export all tables from Oracle database to SQL Server, I suggest you use SQL Server Import and Export Wizard. Because you just need to follow the wizard with GUI, this is the easiest way.
If you want to make some modification for the tables‘ data before loading to SQL Server, I suggest you use SQL Server Integration Services package. For more details, please refer to the following similar thread:
https://social.msdn.microsoft.com/Forums/sqlserver/en-US/38b2bed2-9d4e-48d4-a33f-1d9eed1c062d/flat-file-to-sql-server?forum=sqldatamining

I can't read in a date from a txt file
Im not sure of the code needed to read in a date from the text file, this is an example of the text file:
1
2
2003
ie,
day
month year
I have to read in this date, this is the set method for the date:
public void setPurchaseDate (int d, int m, int y)
new Date(d,m,y);
And this is the code that I have tried using to readin the date:
PurchaseDate=(Integer.parseInt(line),Integer.parseInt(line),Integer.parseInt(line));now i know its wrong, I just dont know what the code should be!!
Cheersok, I am going to go through it and see what values I can and cant read in, here is the code i am trying to use:
private void addx()
FileReader fin;
int noBooks;
int itemNum;
String title;

double costNew;
double costPaid;
String isbn;
double sellingPrice = 0;
int noAuthors;
int day;
int month;
int year;
String seperator = "#";
Book[] book = new Book[9];
try
fin = new FileReader("Books.txt");
BufferedReader buff = new BufferedReader(fin);
String line = buff.readLine();
int count= 0;
//read in Number of books
noBooks=Integer.parseInt(line);
while( line != null)
//Read in item number
itemNum = Integer.parseInt(line);
//Read in title
title = buff.readLine();
//Read in number of authors
noAuthors=Integer.parseInt(line);
//Read each line in as an author until number of authors reached
ArrayList authors = new ArrayList();

I'm trying to read some XML data from temperature logger over my network. I'm using LabView version 2009 sp1. I'm using the URL Get Document Vi. It works fine when using Internet sites like google or foxnews etc...
When I use it with my temperature logger most of the time I get an Error 66...but some times it does work and actually retrieves the document.
I can use the same address "http://172.22.21.68/XMLfeed.rb" (Internet Explorer or Google Chrome) in my browser and get a response every time. When accessing from my browser the server in the temperature logger does take around 6 seconds to respond, but it does respond every time.
Is the URL Get Document Vi exceeding a timeout? If so, where can I set it to wait longer?
Attachments:
Error 66.jpg 183 KBIt looks like the TCP Buffered Read has a 2.5 sec timeout, I believe that is where I had trouble as well. Try creating your own URL Get HTTP Doc vi in which you call URL Get Document in normal mode, with an appropriate number of characters to fetch (enough characters so that you capture all the important data in the XML file).

Hi Connoisseur
The data transfer from Abap WebDeypro to flex island works well. I followed , there is an example from Thomas Jung (by the way as always Great Work) and Karthikeyan Venkatesan (Infosys) but this example covers simple type only.
There is no example with complex types like arrayCollection which handle the transfer of data from flex to WebDynpro.
i tried to do pass internal table value to flex-datagrid.but its not work.
i would like to know
1.how to access internal table data from webdynpro to Flex application.
2.how to pass the internal table to flex-datagrid.
2.how to pass dynamically in ADOBE flex.

A CSV file is a flat file and don't have "Sheets"; you would have to Export to an Excel file, which supports several Sheets in one file.
