Reading Data using TEXT_IO
Dear all
Using TEXT_IO in forms 10G.
Is there any way to read the last line 1st from a text file ?
Or
Is there any way to read the line 1st which is starting from 9 ?
My file format is :
01231823uery1234
12342034dfw 9efjn
184rywuefy34r3489
9473733893 nfjjejh
No. There is no method to move the pointer in the file. If you want to get the nth line, you have to use the Get_Line() method n times.

How to read data using SQLGetData from a block, forward-only cursor (ODBC)
Hi there. I am trying to read data a small number of rows of data from either a Microsoft Access or Microsoft SQL Server (whichever is being used) as quickly as possible. I have connected to the database using the ODBC API's and have run a select
statement using a forward-only, read-only cursor. I can use either SQLFetch or SQLExtendedFetch (with a rowset size of 1) to retrieve each successive row and then use SQLGetData to retrieve the data from each column into my local variables. This
all works fine.
My goal is to see if I can improve performance incrementally by using SQLExtendedFetch with a rowset size greater than 1 (block cursor). However, I cannot figure out how to move to the first of the rowset returned so that I can call SQLGetData to retrieve
each column. If I were using a cursor type that was not forward-only, I would use SQLSetPos to do this. However, using those other cursor types are slower and the whole point of the exercise is to see how fast I can read this data. I can
successfully read the data using a block forward only cursor if I bind each column to an array in advance of the call to SQLExtendedFetch. However, that has several drawbacks and is documented to be slower for small numbers of rows. I really
want to see what kind of speed I can achieve using a block, forward-only, read-only cursor using SQLGetData to get each column.
Here is the test stub that I created:
' Create a SELECT statement to retrieve the entire collection.
selectString = "SELECT [Year] FROM REAssessmentRolls"
' Create a result set using the existing read/write connection. The read/write connection is used rather than
' the read-only connection because it will reflect the most recent changes made to the database by this running
' instance of the application without having to call RefreshReadCache.
If (clsODBCDatabase.HandleDbcError(SQLAllocStmt(gDatabase.ReadWriteDbc, selectStmt), gDatabase.ReadWriteDbc, errorBoxTitle) <> enumODBCSQLAPIResult.SQL_SUCCESS) Then
GoTo LoadExit
End If
Call clsODBCDatabase.HandleStmtError(SQLSetStmtOption(selectStmt, SQL_CONCURRENCY, SQL_CONCUR_READ_ONLY), selectStmt, errorBoxTitle)
Call clsODBCDatabase.HandleStmtError(SQLSetStmtOption(selectStmt, SQL_CURSOR_TYPE, SQL_CURSOR_FORWARD_ONLY), selectStmt, errorBoxTitle)
Call clsODBCDatabase.HandleStmtError(SQLSetStmtOption(selectStmt, SQL_ROWSET_SIZE, MAX_ROWSET_SIZE), selectStmt, errorBoxTitle)
If (clsODBCDatabase.HandleStmtError(SQLExecDirect(selectStmt, selectString, Len(selectString)), selectStmt, errorBoxTitle) <> enumODBCSQLAPIResult.SQL_SUCCESS) Then
GoTo LoadExit
End If
' Cursor through result set. Each time we fetch data we get a SET of rows.
sqlResult = clsODBCDatabase.HandleStmtError(SQLExtendedFetch(selectStmt, SQL_FETCH_NEXT, 0, rowsFetched, rowStatus(0)), selectStmt, errorBoxTitle)
Do While (sqlResult = enumODBCSQLAPIResult.SQL_SUCCESS)
' Read all rows in the row set
For row = 1 To rowsFetched
If rowStatus(row - 1) = SQL_ROW_SUCCESS Then
sqlResult = clsODBCDatabase.HandleStmtError(SQLSetPos(selectStmt, row, SQL_POSITION, SQL_LOCK_NO_CHANGE), selectStmt, errorBoxTitle)
Call clsODBCDatabase.SQLGetShortField(selectStmt, 1, assessmentRollYear(row - 1))
Console.WriteLine(assessmentRollYear(row - 1).ToString)
End If
Next
' If the rowset we just retrieved contains the maximum number of rows allowed, there could be more data.
If rowsFetched = MAX_ROWSET_SIZE Then ' there could be more data
sqlResult = clsODBCDatabase.HandleStmtError(SQLExtendedFetch(selectStmt, SQL_FETCH_NEXT, 0, rowsFetched, rowStatus(0)), selectStmt, errorBoxTitle)
Else
Exit Do ' no more rowsets
End If
Loop ' Do While (sqlResult = enumODBCSQLAPIResult.SQL_SUCCESS)
The test fails on the call to SQLSetPos. The error message I get is "Invalid cursor position; no keyset defined". I have tried passing SET_POSITION and also SET_REFRESH. Same error. There has to be a way to do this!
Thank you for your help!

Problem in reading data using scanner
In a client - server application,Iam sending the data "~!Raam7krishna~!" continously to the server periodically.... In the server side,Iam using scanner to read the data with the delimiter ~!. Server should continously read the data from the client.so iam using infinite for loop to read the data from the inputstream using scanner..
Problem is when a client send the data first time,i am received the data correctly in server side... At the second time of transmission of data from client to server,Server should not read any data .... but it does not throw any exception... but my client send the data to the server.... can anyone give me solution......

Read data using 2 diff connection pool for same DB folder in physical layer
Hi All,
i am using two connection pool which have different dsn connection information (both are directed to different database name or database server)..
so if i view the data of any table, a prompt will come asking for the connection pool, so how do i automize it....?
how do i set the different connection pool for different tables?
please let me know if u need further informtaion to understand my problem..
thnx...thnx Stijn..
yupe that i know...
actually i have total of around 300 tables in physical layer (in both the schemas..) , around 12 fact and 100 dimension tables in bmm and same in the presentation layer...
so i think u can guess how many joins and other stuff, i have made in my bmm layer..
if now i will start modifying all this it will take lot of time...
i am just wondering that there is no alternative for this...
as when i check my data from the physical layer then a prompt ask for the connection pool (i have already made two connection pool..) so there could be some alternative way to automize the default connection pool setting for the tables/schemas folders in case if more than one connection pool exits under the same database in the physical layer...
isn't it?
thnx again.. -
Error while reading data using Function Module /sapapo/msdp_data_read
In my report, function module /sapapo/msdp_data_read is called to get the data from a planning area.
The problem is that, the values returned by this FM are not correct.means its returning wrong Key_figure values.
On checking it was observed that , in the import parameter is_read_options ,
the field flg_aggregate = 'X'.
In Debug mode i cleared this field and called the FM and it returned the correct values.
Can anybody plz tell me what is the relevance of this field flg_aggregate .
Kindly guide.
Thnk you in advance.
Regards ,
PranaliDear Pranali,
FLG_AGGREGATE has following importance:
if FLG_AGGREGATE = 'X' and the table ct_cols is empty then key figures for the time period defined through IS_PERIOD will be red aggrerated.
I hope this helps.

Is it possible to read digital data using an external clock (PCI-6259 M)?
I’m using a NI PCI-6259 M Series card and trying to write my program in VC++6.0 using the functions in the DAQmx driver.
Question1: Not all functions listed in the NI-DAQmx C Reference Help seems to be supported by my NI-card, where can I find information about which of the functions that are supported?
Question2: I want to read data from a device that clock out data on the falling edge of a clock signal. The clock signal and the data signal are routed to two DIO terminals on the NI-card. The question is if it is possible to read data using the clock as a sample clock? See two code examples below that doesn’t work. In both cases 10 samples are read at once, even if the external clock is not present.
Example 1
// Create tasks
Status = DAQmxCreateTask("", &m_ReadTrimTask);
// Set up read task
status = DAQmxCreateDIChan(m_ReadTrimTask, "Dev1/port2/line0", "", DAQmx_Val_ChanPerLine);
status = DAQmxCfgChangeDetectionTiming(m_ReadTrimTask,"Dev1/port2/line6","Dev1/port2/line6",DAQmx_Val_FiniteSamps, 10);
// Read data
int32 sampsPerChanRead, numBytesPerSamp;
status = DAQmxReadDigitalLines(m_ReadTrimTask, 10, 10.0, DAQmx_Val_GroupByChannel, result, 10, &sampsPerChanRead, &numBytesPerSamp ,NULL);
Example 2
// Create tasks
Status = DAQmxCreateTask("", &m_ReadTrimTask);
// Set up read task
status = DAQmxCreateDIChan(m_ReadTrimTask, "Dev1/port2/line0", "", DAQmx_Val_ChanPerLine);
status = DAQmxSetSampTimingType(m_ReadTrimTask, DAQmx_Val_SampClk);
status = DAQmxSetSampClkRate(m_ReadTrimTask, 1000.0);
status = DAQmxSetSampClkActiveEdge(m_ReadTrimTask, DAQmx_Val_Falling);
status = DAQmxSetSampClkSrc(m_ReadTrimTask, " Dev1/port2/line6");
// Read data
int32 sampsPerChanRead, numBytesPerSamp;
status = DAQmxReadDigitalLines(m_ReadTrimTask, 10, 10.0, DAQmx_Val_GroupByChannel, result, 10, &sampsPerChanRead, &numBytesPerSamp ,NULL);Hello Magnus,
Thank you for contacting National Instruments.
"Question1: Not all functions listed in the NI-DAQmx C Reference Help seems to be supported by my NI-card, where can I find information about which of the functions that are supported?"
The best place to look for this information would be the M Series Help Manual. There you can find the features of your PCI-6259 and what operations it supports.
"Question2: I want to read data from a device that clock out data on the falling edge of a clock signal. The clock signal and the data signal are routed to two DIO terminals on the NI-card. The question is if it is possible to read data using the clock as a sample clock? See two code examples below that doesn’t work. In both cases 10 samples are read at once, even if the external clock is not present."
Look at the "ContReadDigChan-ExtClk_Fn.c" example project which ships with the NI-DAQ driver. This is located at: C:\Program Files\National Instruments\NI-DAQ\Examples\DAQmx ANSI C\Digital\Read Values\Cont Read Dig Chan-Ext Clk.
You will have to make some minor modifications to convert this to a finite acquisition, but that is simply a matter of changing the "sampleMode" parameter of the DAQmxCfgSampClkTiming() function. You will also have to route your clock signal to a PFI line and specify which line in your code.
I hope this helps.

Read data from a Stored Procedure in Android
I have a Stored Procedure say CustOrdersDetail. I have created a MBO for it in the workspace and deployed it on SAP Mobile Server. I am unable to read data from the stored procedure in code of the Android Application. If I pass a default load argument, then I am able to read data using findAll method. How to get the data from the stored procedure by passing it an argument in the Android Code ?
Message was edited by: Abhijit KadamCurrently I am trying to call the stored procedure and retrieve the results. The stored procedure accepts 'orderId' as an argument and fetches the Product and Order Details.

Hi,
I am new user to webdynpro and has the task of reading data from XML file.The file is created using XML form Builder and is stored at a location.But my code gives me the path instead of the content in the data.
The code is :
try
IWDClientUser wdClientUser = WDClientUser.getCurrentUser();
com.sap.security.api.IUser sapUser = wdClientUser.getSAPUser();
// create an ep5 user from the retrieved user
IUser ep5User = WPUMFactory.getUserFactory().getEP5User(sapUser);
IResourceContext context = new ResourceContext(ep5User);
/Specify the path of ur document here./
RID pathRID = RID.getRID("/documents/70f51182-84c3-2710-ce91-8d5fbfde713d.xml");
//RID pathRID = RID.getRID("/documents/hol.txt");
wdContext.currentContextElement().setSetDisp(pathRID.toString());
IResource resource = ResourceFactory.getInstance().getResource(pathRID, context);
InputStream in = resource.getContent().getInputStream();
ByteArrayOutputStream out = new ByteArrayOutputStream();
byte[] buffer = new byte[4096];
int bytesread = 0;
while ((bytesread = in.read(buffer)) != -1)
out.write(buffer, 0, bytesread);
String myData = out.toString();
/*myFile will containS the content of the document./
wdContext.currentContextElement().setSetDisp(myData);
catch (Exception e)
// wdContext.currentContextElement().setTextdisp("IO Error:" + e.getMessage());
text data is read from the location but XML data is not read.
Please help me out.hi SriRam,
For some reasons you are not able to change the value of attribute SetDisp ahich you gave the default value as the path using the following statement
wdContext.currentContextElement().setSetDisp(myData);
Remove that line.First try to open the files using creating new window instance
IWDWindow window =
wdComponentAPI.getWindowManager().createExternalWindow(
"http://<server name>:<port no>/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs"
+ "/documents/Public Documents/...."
+ "/"
+<name>,
"from km repository",
false);
window.open();
Then we can be sure that the error is due to reading data using input stream

Server Socket does not read data input stream
Hi all,
I am very newbie to Java Network programming with sockets and multi-threading.
But I am obliged to develop a chat system written in Applets which can be placed on the website and used by visitors who come to my website.
In order to understand this, I have tested a basic web chat program I downloaded from the Internet which use sockets and multi-threadings. The program work fine, no bugs at all at both compilation and run time. I noticed that all three streams for Client side (i.e. first one is input stream used receiving data from User; the second one is socket input stream used for receiving data from Server socket, and the third is socket output stream used for writing data to server socket) were established. And the same, two socket streams (input & output) for Server side were also connected when running program giving right port number and IP address of the server.
The problem is both server and client sockets do not read data using the following stream classes:
1. DataStreamInput: I use input.readUTF() method
2. or BufferedReader: I use input.readLine() method
The example of the codes are below:
private BufferedReader input = null;
private PrintWriter output = null;
private Socket socket = null;
public void open() throws IOException
{ input = new BufferedReader(new
InputStreamReader(socket.getInputStream()));
System.out.println("Server socket input stream was created, and");
output = new PrintWriter(socket.getOutputStream());
System.out.println("Server socket output stream was created");
public void run()
{ System.out.println("Server Thread " + clientPort + " running.");
while (true)
{ try
System.out.println("Server is reading data from Client, wait...");
String fromClient = input.readLine();
System.out.println("Server received a message on " + clientPort + ".");
catch(IOException ioe)
{ System.out.println(clientPort + " ERROR reading: " + ioe.getMessage());
server.remove(clientPort);
stop();
The problem is at the line: String fromClient = input.readLine(); in the run() method? What is wrong with the codes above?
Note: I also try to use original codes which use readUTF() method in DataStreamInput class instead using readLine() in BufferedReader. Both methods dont read data from inputstream socket?
I very appreciate any help/advice from experienced developers.
Best regardsHi,
Yes. The readLine() method hangs! After the test, the execuation of the program is stopped at the line of readLine() method; it does not pass it?
There is no problem with writing to Server socket. After the test, the program pass through flush() method. Here is the code for writing to sever socket within ChatClient (client side socket) class:
private BufferedReader input = null;
private PrintWriter output = null;
public ChatClient(String serverName, int serverPort)
{ System.out.println("Establishing connection. Please wait ...");
try
{ socket = new Socket(serverName, serverPort);
System.out.println("Connected: " + socket);
start();
catch(UnknownHostException uhe)
{ System.out.println("Host unknown: " + uhe.getMessage()); }
catch(IOException ioe)
{ System.out.println("Unexpected exception: " + ioe.getMessage()); }
public void start() throws IOException
{ input = new BufferedReader (new
InputStreamReader(System.in));
System.out.println("Client User input stream was created,");
output = new PrintWriter(socket.getOutputStream());
System.out.println("Client Socket output stream was established, and");
if (thread == null)
{ client = new ChatClientThread(this, socket);
thread = new Thread(this);
thread.start();
public void run()
while (thread != null) {
String fromUser;
try{
while((fromUser = input.readLine())!= null)
System.out.println("Client wasreading a data from User, and");
output.println(fromUser);
output.flush();
System.out.println("Client has written a data to Server");
catch(IOException ioe)
{ System.out.println("Sending to server error: " + ioe.getMessage());
stop();
etc.
Here is a piece of codes for reading data from the Client Socket in the ChatServer Class (Server Side socket):
public void run()
{ System.out.println("Server Thread " + clientPort + " running.");
while (true)
{ try
{ //server.handle(clientPort, input.readLine());
System.out.println("Server is reading data from Client, wait...");
String fromUser = input.readLine();
//while((fromUser = input.readLine()) != null)
System.out.println("Server received a message on " + clientPort + ".");
catch(IOException ioe)
{ System.out.println(clientPort + " ERROR reading: " + ioe.getMessage());
server.remove(clientPort);
stop();
etc. Please advice why the readLine() method hangs; does not read data from the input stream received from the CLIENT? -
wht happens if v read data using FOR ALL ENTRIES in select statement
Hi Ankur,
You can only use FOR ALL ENTRIES IN ...WHERE ...in a SELECT statement.
SELECT ... FOR ALL ENTRIES IN itab WHERE cond returns the union of the solution sets of all SELECT statements that would result if you wrote a separate statement for each line of the internal table replacing the symbol itab-f with the corresponding value of component f in the WHERE condition.Duplicates are discarded from the result set. If the internal table itab does not contain any entries, the system treats the statement as though there were no WHERE cond condition, and selects all records (in the current client).
For Example:
SELECT *
FROM SCARR
INTO TABLE t_scarr.
LOOP AT t_SCARR INTO wa_scarr.
SELECT SINGLE *
FROM sflight
INTO wa_sflight
WHERE carrid EQ wa_scarr-carrid.
APPEND wa_sflight TO t_sflight.
ENDLOOP.
Instead of the Above use below code:
SELECT *
FROM SCARR
INTO TABLE t_scarr.
SELECT *
FROM SFLIGHT
INTO TABLE t_sflight
FOR ALL ENTRIES IN scARR
WHERE carrid EQ t_scarr.
this condition, return all entries of the sflight

I have to check the file :-
Validation are 1st line should start from 0 else it should raise an error and insert that error into one table .
The for 2nd line also same thing ..it should start from 9 else it should raise an error and insert that error into one table .
Then the 3rd line should start from 1 else it should raise an error and insert that error into one table .
After that i have to do a validation like i will read the 1st line 2nd column .. It should be like this BP-V1 else raise an error and insert that error to a table . Then i will check the 3rd column which is 20100928 , it should be YYYYMMDD format else same thing ERROR.
Then like this for all columns i have different validation .......
Then it will check for the 2nd line 3rd column . this is an account no .1st i will check it should be 12 char else ERROR .Then I will check that what user has imputed in the form.Like for example User putted 111111111 then i will check with this 000111111111 which is there in the 2nd line . I have to add 000 before that Account no which user imputed .
Then the lines which is starting from 1 , i have to take all the 2nd column for all the lines which is starting from 1 and i have to do a sum . After that i have to compare that sum with the value in the 1st lines ( Starting from 0) 6th column . It should be same else ERROR ...
Then same way i have to count all the lines which is starting from 1 . Then i have to compare with the 7th column of 1st line . It should be same . Here in this file it should be 9.

Reading a copy 'end-of-file' marker using TEXT_IO
Hi
I am using TEXT_IO to read a file, but the in the file there are special characters such as
,' ' which I think are "end of file marker" 1A hex, which 'COPY' adds to the end of and ascii copy.
I'm using Oracle forms 6i, and when reading the above characters it raises unhandled exception ORA-01403, even though it hasn't reached the end of file.
Can anyone help or advaise a way to avoid this problem?
Thank You & Regards
BegumOne method is to save your data using the "write to spreadsheet file" vi, using whatever delimiter you choose (usually either comma ro tab char). This gives a file that can be opened with a text editor or Excel, and consists of rows of "numbers" seperated by the delimiter with an end of line char at the end of each row. When read back in using the "Read from Spreadsheet file", you can define how the values will be interpreted, either as numbers or as characters. The read data will be returned as a 2D array. This array can be indexed, either by autoindexing with loops, or by explicitly indexing to retrieve specific values (A[2,7]) and the returned values used however you wish.

How to read an html file and replace a text using text_io
hi,
i want ro read an html file using text_io and replace a particular text with a new text
eg: i want to replace a text called "data.js" and with "maps.js"
how do i do this?You have to write your own code to do that. TEXT_IO is just a low level text file interface.
You need to read in all the text, save it in some internal format (array of varchar2's maybe or in the DB) and then perform a search on the text you have read in, find out where the instances of "data.js" are located and substitute them with "maps.js" After that you need to write to a new file and delete the old one. There is no way to search and replace inside the existing file (what's sometimes referred to as 'in-place' substitution).
See the help section called About the TEXT_IO package for an overview of how it works and some code examples. -

How to write data to a file without leaving any blank lines in the file? How to check if the cursor is placed in the corner of a notepad file using LAB VIEW?
If you write data to a file, simply don't include any blank lines. We cannot give more specific advice unless you are telling us how you are writing. Are you writing to a new file or appending to an existing file. If the blank lines already exist, you need to read the entire file, remove the undesired lines from the string, and write the data back.
Notepad files don't have any "corners". Please describe what you are trying to do.

Help Required -- Can we use SQL Query to READ data from SAP MDM Tables
Hi All,
Please help.........
Can we use SQL Query to READ(No Creation/Updation/Deletion just Read) Data from SAP MDM tables directly, without using MDM Syndicator.
Or direct SQL access to SAP MDM tables is not possible. Only through MDM Syndicator can we export data.
Thanks in Advance
RegardsAll the tables you create in Repository comes under A2i_CM_Tables in Database named as your repository name. So the tables names are fields of table A2i_CM_Tables. Now i tried it but cant make it.
Now, I dont think its possible to extract all fields in tables and there values using select query. May be pure sql guy can do that or not.
But there is no relation of data extraction and syndicator. Data is viewed in Data Manager. and you can also store data in a file from DM also.
BR,
