How to get error's field name when execute sql error

I want to get the error's field name when execute sql error,but SQLException is not provide corresponding function to get it.
How can I do for it?

user523110,
I believe the "unique constraint" error message displays the name of the constraint, not the column name, as you have posted.
As far as I know, the only way to extract the column(s) would be to query the data dictionary using the constraint name provided in the error message.
Also, as far as I know, there is nothing in the JDBC API that can return the names of the columns associated with a given unique constraint.
Good Luck,
Avi.

    Hi,
    Am facing the same issue stated above that I couldnt get all the records in the table that am querying in the Proxyservice.
    For example:
    fn-bea:execute-sql('EsbDataSource', 'student', 'select Name from StudentList' ) is the query that am using to fetch the records from the table called StudentList which contains more than one records like
    Id Name
    01 XXX
    02 YYY
    03 ZZZ
    I tried to assign the result of the above query in a variable and while trying to log the variable, I can see the below
    <student>
    <Name>XXX</Name>
    </student>
    I want to have all the records from my table in xml format but it's not coming up. I get the value only from the first row of my table.
    Please suggest.

  • How to get the main funciton name when calling another function inside?

    for eg, one RFC named A,inside A,a funtion B is called.when the processing is at B now,how can i get the main RFC name(A)?
    any help will be much appricated.

    > just see SM50,there is a column called 'Report',it shows the program id the proess is now processing.but i don't know its main program or say it 'the process's first excuting program',how can i get it programmatically?
    I'm still not sure to understand. The program in SM50 is the current main program (not the first). It is stored in SY-REPID system variable. Or use this code:
    DATA lt_callstack_long TYPE abap_callstack.
    DATA ls_callstack_long TYPE LINE OF abap_callstack.
    CALL FUNCTION 'SYSTEM_CALLSTACK'
          IMPORTING
            callstack    = lt_callstack_long.
    READ TABLE lt_callstack_long INDEX 1 INTO ls_callstack_long.
    WRITE : / 'current main program is:', ls_callstack_long-mainprogram.
    If you want to know the frame program (the first called), use SY-CPROG, or use this code:
    DATA lt_callstack_long TYPE abap_callstack.
    DATA ls_callstack_long TYPE LINE OF abap_callstack.
    CALL FUNCTION 'SYSTEM_CALLSTACK'
          IMPORTING
            callstack    = lt_callstack_long.
    " read last line = first called program
    DESCRIBE TABLE lt_callstack_long. "to make sy-tfill = number of lines
    READ TABLE lt_callstack_long INDEX sy-tfill INTO ls_callstack_long.
    WRITE : / 'First main program is:', ls_callstack_long-mainprogram.

    I need path and have to calculate MD5, Presumably you need to calculate MD5 on the contents of the file and not on the name of the file.
    and convert the file to binary format.... etc oprations on itSorry, "convert a file to binary format" is basically meaningless.
    but we can get the content of the file using
    byte [] get()/ getString() methods
    If i get content is there any performance degrades?
    ie if the content is lengthy is it take more time?Take more time than what? Degrading performance from what? It's certainly true that it would be quicker to not upload the file, but that's a pointless comparison. If you have some other process to compare with, let us know what it would be.

  • Field name is not know error when trying to add a filter

    Hello all!
    I need to add a filter dinamically to display a report. I'm using Crystal Reports 10 w/ RAS server.
    There is an sql statement in Database Fields > Command. It uses a join and a correlation name for table name: TT.START_TIME.
    I am getting a "Field name is not known" error:
    "This field name is not known. Details: errorKind Error in File C:\WINDOWS\TEMP\{D375AB61-F7AE-4BCC-AF5E-6702C0EFDE10}.rpt: Error in formula . '{Command.TT.START_TIME} in DateTime (2007, 08, 01, 09, 00, 00) to DateTime (2007, 08, 24, 04, 45, 00)' This field name is not known. Details: errorKind"
    I tried to specify the field the following ways:
    Command.START_TIME
    TT.START_TIME
    START_TIME
    TIME_TRACKER.START_TIME (time_tracker being the table name)
    MAIN.TIME_TRACKER.START_TIME (main being the schema)
    All of the above is giving the same field name not known error.
    I am adding the filter the following way:
            String whereClause = "{Command.TT.START_TIME} in DateTime (2007, 08, 01, 09, 00, 00) to DateTime (2007, 08, 24, 04, 45, 00)";
            IFilter filter = rptClientDoc.getDataDefinition().getRecordFilter();
            filter.setFreeEditingText(whereClause);
            rptClientDoc.getDataDefController().getRecordFilterController().modify(filter);
    I also tried the following where clause:
    String whereClause = "{Command.TT.START_TIME} > DateTime (2006, 08, 01, 09, 00, 00) AND {Command.TT.START_TIME} < DateTime (2007, 08, 24, 04, 45, 00)";
    still doing the same thing.
    If anyone could please help me w/ this I'd really appreciate it!
    Thank you!
    Anastasia

    The first formula was created using the selection formula expert. I only added the TT part after it didn't work giving the same message. The name the expert gives it after I click on the field is {Command.START_TIME}. Still gives the invalid field name error. -_- Could the rest of the forumula be causing the problem?
    In regards to parameterizing the SQL Command, I spoke w/ the gentleman who creates these reports in Crystal, he says it's not possible, because sometimes we don't want a where clause and sometimes we do.
    Is there a way to directly edit the SQL string itself which is in the Command through java?
    Thank you very much for taking time to respond.

  • Crystal Report Windows Forms Viewer error: "The field name is not known"

    Hi,
    My report runs fine in the Crystal Reports viewer.  When we try to view the crystal report through a piece of 3rd party software, I start to get errors in a few of my formulas indicating that "the field name is not known".  I can clearly see that the field is in my crystal report.  Has anyone else had this problem?  Any ideas on what might be happening?
    Thank you.

    Just to provide some further clarification on my problem:
    The "field name is not known" error seems to be occurring only in a few formulas where I have a statement like this:
    if ISNULL({somefieldfromdatabase}) Then
    I've used this for many other formulas and not had an issue with them.  I've verified that the database and the stored procedure contain this field.

    ok folks, I found the answer at Tom's as usual.
    http://asktom.oracle.com/tkyte/who_called_me/index.html
    I rewrote it into a function for kicks. just pass the results of DBMS_UTILITY.FORMAT_CALL_STACK to this function and you will get back the owner of the code making the call as well some extra goodies like the name of the code and the type of code depending on the parameter. This ignores the AUTHID CURRENT_USER issues which muddles the schemaid. Quick question, does the average user always have access to DBMS_UTILITY.FORMAT_CALL_STACK or does this get locked down on some systems?

    Restore
    Note: Because Restore erases all of the songs and files on iPod, make sure toback up any files you've saved on the iPod disk. All of your songs, videos, podcasts, audiobooks, and games can be loaded back to your iPod provided that you have them stored in your iTunes Library.
    How to restore your iPod:For Windows:
    1. Make sure you've reinstalled the latest version of iTunes.
    2. Open iTunes, and then connect your iPod to your computer.
    3. After a few moments, it will appear in the source list in iTunes. If the iPod's display doesn't show "Connected" or "Do not disconnect" you may need to put the iPod into disk mode to proceed.
    4. Select your iPod in the source list and you will see information about it appear in the Summary tab of the main iTunes windows.
    5. Click the Restore button. You will be prompted with one or more restore options that may prompt iTunes to automatically download of the latest iPod Software. The 4 possible restore options are:
    Restore Option 1: Restore - Restores with same iPod Software version already on iPod.
    Restore Option 2: Use Same Version - Restores with same iPod Software version already on iPod even though a newer version is available.
    Restore Option 3: Use Newest Version - Restores with the latest iPod Software on your computer.
    Restore Option 4: Restore and Update - Restores with the latest iPod Software on your computer.
    6. A progress bar will appear on the computer screen indicating that the first stage of the restore process has started. When this stage is completed, iTunes will instruct you to leave iPod connected to your computer to complete restore.
    7. During the stage 2 of the restore process, the iPod will show an Apple logo as well as a progress bar at the bottom of the display. It is critical that the iPod remains connected to the computer or iPod Power adapter during this stage. Note: The progress bar may be difficult to see since the backlight on the iPod display may be off.
    8. After stage 2 of the restore process is complete and the iPod is connected to the computer, the iTunes Setup Assistant window will appear asking you to name your iPod and choose your syncing preferences similar to when you connected your iPod for the first time.

    hai, how to get the full image directory when i upload the image to web page???
    here is the example:
    <form action="uploadfile.jsp" method="post">
    image<input type="file" name="image" />
    <input type="submit" value="submit"/>

    String s=request.getParameter("image");

    </form>
    i upload the image from C:\image\center.gif. i use request.getParameter just can get the image name like "center.gif". Can anybody help me how to get the full path name. Thanks a lot..

    There is no need to get the path. It is also fairly pointless as the server cannot access the client's local file system.
    Carefully read this article how you can upload files the right way: http://balusc.blogspot.com/2007/11/multipartfilter.html

  • How to get the actual font name from a font file?

    Hi
    I have only the font Path I have to get the font name from that path. Any idea how to get the actual font name?
    Thanks,

    I would ask you these questions:
    Why do you need to do this?  What are you ultimately trying to accomplish?
    Are you really asking about the InDesign SDK?
    Do you really need to get the "name" of a font from an arbitrary file?  Or do you want information about a font installed on the system?  If so, what OS?
    Do you need to be able to handle any font format?
    Which font "name" do you mean?
    What language do you want the name in?
    (1) It's not clear what you're trying to accomplish.  A bit more information about your ultimate goal would be helpful.
    (2) This question is not at all specific to the InDesign SDK.  Are you really trying to do something in the context of an InDesign plug-in?  If so, you probably want to look at IID_IFONTFAMILY and the IFontFamily::GetFamilyName function.
    (3) If you are asking more generally, Windows and Mac both have system API calls to get this information, although those tend to deal with installed system fonts, not with arbitrary font files per se.
    Also, you can parse the name table from a True Type or Open Type font without using any system APIs; as True Type and Open Type are well-documented standards.  I would start by reading these:
    The Naming Table
    Font Names Table
    (4) Although there are other standards, such as Type 1 (PostScript) fonts, and True Type Collection files and other formats, especially on Mac.
    (5) Also, when you start down this road, you will quickly realize that your seemingly simple question is actually ambiguous, and that the answer is kind of complicated, because a font can have many names (a family name, a full font name, a style name, a PostScript name, etc.).
    (6) And not only does a font have multiple names, it can have each of those names in multiple languages and encodings.
    Any clarification would make this a better question.

  • How to get orchestration instance server name

    I have two server where orchestration can run...I need to know the server name where my orchestration instance has run.
    How to get this information...

    When you have more than one BizTalk-processing server and if your orchestration is bound to host instance which exist in more than one server (generally for better resilience, the best practice
    is to have multiple instances of host in different servers), the idea of get the server name where Orchestration instance has run is INVALID.
    With the BizTalk features like scalability, resilience and persistence points an Orchestration instance could run in more than one server.
    For example due to persistence points, if that BizTalk server were to suffer a power outage, another BizTalk server could continue the orchestration from the checkpoint rather than having
    to start the orchestration from the beginning. Or during or during long-running process while waiting for a response, then message being consumed by an orchestration instance would be persisting the in-memory representation of an orchestration (to its last
    good state) and any associated messages in BizTalk MessageBox. So when the response comes back the rest of the part of orchestration could execute from other server instance. So an orchestration would not always run from one server.
    But if you have specific “Expression shape” which you may have been using for logging/tracing then you can get the server name which executed that particular “Expression shape” from an Orchestration
    instance (not the whole Orchestration instance). This is done using the standard .NET code to get the server name -
    System.Environment.MachineName
    If this answers your question please mark it accordingly. If this post is helpful, please vote as helpful by clicking the upward arrow mark next to my reply.

  • Field name is not known Error in formula field...

    Hi,
    I have a report in CR11.5 r2 that I call from VB6.
    The report works fine, until a I create this formula, Trim ({RSE.PatName}).
    When I put this formula field in a section in the report, I have this error, "Field name is not known Error".
    Any idea?

    Make sure you have SP 6:
    https://smpdl.sap-ag.de/~sapidp/012002523100015859952009E/crxir2win_sp6.exe
    Does the formula work in the designer?
    Are you changing datasource at runtime? If so, can you change to that datasource in the designer and run the report there?
    If you do not use the Trim function, does it work?
    If you do not use the field in a formula abd place it in say, the detail section as a test, does the report work?
    But remember that what ever the report is doing at runtime, must work in the designer 1st.
