• retrieve a row of data from mysql database

  Hello

  I extract data from a database.  Use of then in a Web page as <? php echo $row ['product'];? >

  However, if there is an apostrophe in 'product', he displays like a diamond with a question mark.

  Data stored in the database looks like this, 'pearls of Mary. "
  

  Is the problem when I have the data stored in the database or when it was recovered?

  Thanks, Dan

  This happens usually if you paste from another application like Word or Xpress directly in the database.

  To work around the problem:

  If you are still using the old mysql extension insert the line below before any other query mysql on your page:

  mysql_query("SET NAMES UTF8");

  If you uisng the new mysqli extension then use the variable of connection string (in this case $conn) as below:

  $conn-> query ("SET NAMES UTF8");

• Display data from another web application

  Hello

  I hope than to display data from my application 'team' on my 'articles' approx. basically display image of the author, email etc., which comes from the app TEAM. I know that this is possible.  I use the data of the src field extract the name of the authors, but of course this provides only a link. Are there tutorials - what can anyone tell me? Thank you.

  So does that mean as a concrete response by using the system of normal with BC, is tag that you insert this code for your team web app {module_webapps, 123456, i, {tag_author_id}} on your layout displayed products app page.  ID tag of the author is a field set up in the articles web app and a field of the data source to connect to your team application.

• Can I import data from a database in a FrameMaker using ExtendScript document?

  I want to import the part of database information in a structured document in FrameMaker (XML). The document would be an illustrated parts catalog, built by merging the text in the document structured with Bill of material stored in a database and graphic files. ExtendScript for this, or do I have to study a different language for this programmatic approach to the construction of a document?

  There is no direct way to connect to a database with FrameMaker ExtendScript. It is possible to write code C++ to interact with scripts, so you could write some kind of connector in C++ that would work with ExtendScript. ExtendScript can work with XML files, then another solution is to export the data from the database in XML format and ExtendScript allows you to analyze and import it into FrameMaker.

  I'd take a serious look at FrameScript. FrameScript has built-in ODBC support, you can connect directly to your database and use SQL queries to get your data into FrameMaker. There also ActiveX is supported, so you can use ADODB technology to get data from your database. I did the import of the database in a bunch of my scripts over the years. Please let me know if you have any questions or comments. -Rick

• How to get data from a database table and insert into a file

  Hello
  I'm new to soa, I want to create an xml with the data from database tables, I'll have the xsd please suggest me how to get the data in the tables and insert in a file
  concerning

  in your bpel process, you can use the db adapter to communicate with the database.
  with this type of adapter, you can use stored procedures, selects, etc to get the data from your database into your bpel workflow.

  When did it call in your bpel to the db adapter process it will return an output_variable with the contents of your table data, represented in a style of xml form.

  After that, you can use the second card (a file synchronization adapter) to write to the content of this variable in output to the file system

• copy data from one database to another

  Hello
  
  I want to copy data from one database to another.
  
  I have two patterns such as
  
  dev1/dev@ORCL
  DEV2/dev@DCEL
  
  
  I have same tables dev1 and dev2 (tables)
  but I have not given in dev2 (tables).
  now, I want to copy dev1 (tables) in dev2 (tables).

  You can also use the database link:

  select * from dev1.emp@orcl;
  

  What database are you connected to?
  You must create and use the links in the database for all other databases.

  For example if you are connected to the database A and to retrieve data from database B, you must create a connection of database in base B

  create database link B connect to  identified by  using 'B';
  

  Then you can retrieve data from database B with

  select * from [yourschema.]yourtable@B;
  

  This will work only for tables that are visible to the user that you used in the definition of database link.

• read data from a database and display them in a listbox

  Hello

  I want to read the data from a table in a database, so I want to display 1 column in a listbox.

  I read the data from database, but I can't display in a listbox control.

  can someone help me please?

  Your VI is way too complicated. If you get a 2D array and you want just the second column, you should only use the Array Index to take off from the second column. That's all.

  Once again, the structure of your sequence is completely useless.

  

  I will reiterate my statement about to spend some time with the LabVIEW tutorials.

• Unable to display data from database using persistence mobile A-team

  Hello

  We use the accelerator of persistence for Mobile A-team with application of the MAF. We built the REST services based for CRUD operations on a table. We are unable to use the POST CREATE service by application of the MAF. We tried using saveTask and addTask data control methods it generates automatically. Although it is saved locally to the iterator of data control, it doesn't push the data from database. We tried to test the service REMAINS independent and works well.

  Can anyone help regarding if lack us measures in the same?

  Thank you

  Vignesh

  Vignesh,

  Indeed, there are two issues here:

  -the attributes of the payload are different

  -the structure of the payload is different, the GET request has an attribute "Task" that returns an array, the POST request submitting a single object through the attribute "taskDetails.

  By default, the accelerator of persistence assumes that the POST request has the same payload structure and attributes as the GET request that you used to 'discover' the data objects.

  However, you can easily change this as follows:

  -To add additional attributes required in the POST, you should restart the wizard REST-JSON directly access the data object attributes screen and click on the button 'add an attribute '. Add each attribute you need in the POST request and the attribute name to the value required in the POST request payload. No matter that this attribute of the payload does not exist in the payload GET, it will be ignored during extraction of the tasks.

  -To fix the second issue, you must change the persistence - mapping.xml:

  -go to the createMethod task

  -Remove the payloadElementName attribute

  -Add the payloadRowElementName attribute and set the value to "TaskDetails.

  It's a little strange that you post in order to get other attributes, it is there another resource GET that returns all attributes for a task?

  In addition, you cannot derive columns audit as created_by on the server-side? It's a bit unusual set these values at the level of the customer.

• Insertion and extraction of data from a database by USING SQL Developer al32UTF8

  Hi guys,.
  
  Before I post my questions, I think it's better for me to give you guys my first understandings so that it is easier to understand where / if I have gone wrong...
  
  I use Windows XP and Oracle 10 g
  ------------------------------------------------------------------------------------------------------------------------------------------------------------------
  
  Non-unicode client - a client program that needs to use the code page of the operating system for the mapping of unicode data retrieved from the database as well as the support to display/insert characters from the code page to the database.
  For example sqlplusw.exe
  
  Therefore, when you use a non-unicode client
  
  (1) we define the code page of the OS (Control Panel - regional and language of the parameter - advance - the language for non-unicode programs) to the code page that contain the characters that we will view/insert.
  
  (2) we also defined the NLS_LANG characterset on the character set of code page, that we'll insert so that when we do an insert (for example in thai), oracle will and automatic conversion to Unicode can take place. This is also true when recover us the database unicode data so that the correct character set conversion can take place.
  
  INSERTION OF
  THAI->-> UNICODE conversion
  
  RECOVERY OF
  THAI <-conversion <-UNICODE
  
  I hope that my basic understanding is correct up to this point.
  ---------------------------------------------------------------------------------------------------------------
  
  Unicode client - a client program that supports display/inserting unicode characters without the need to set the code page of the operating system (Control Panel - regional and language setting - control - language for non-unicode programs advance)
  For example isqlplus http or SQL Developer
  
  However,.
  
  (1) there are still set the NLS_LANG so that the correct conversion can take place between the client and the database.
  For example, when the recovery if we set NLS_LANG value ZHS16GBK (Chinese) character and store data in Unicode in the database is for example (THAI), then the conversion would be a mistake.
  It's a supported unicode client, then the NLS_LANG character set should be set to UNICODE as well.
  
  ---------------------------------------------------------------------------------------------------------------------------
  
  Those are my questions
  * Important - please help if you're busy and don't have the time to answer the remaining questions
  
  (* Q1) if I had to use a unicode client, what should I put my character NLS_LANG set?
  AMERICAN_AMERICA. UTF8?
  
  (* T2) where can I put the NLS_LANG information of character in SQL Developer, I know there is a metalink for setting NLS_LANG using isqlplus but I cant seem to google each led for SQL developer.
  
  Q3) is my basic understanding of up to this point? If no, please explain in a term more widespread that I'm really not familiar with character sets code page, unicode and fonts, glyphs...
  
  A unicode client (Q4) didn't need to refer to the OS codepage (regional and language updates), y at - it a code page UNICODE for the customer to refer to, or is there an available window API?
  
  Q5)

  , there are still set the NLS_LANG so that the correct conversion can take place between the customer and the > > database.
  For example, when recovery if we set NLS_LANG value ZHS16GBK (Chinese) character and the data store in > > unicode in the database is for example (THAI), then the conversion would be erroneous.

  I'm just on this point for customer UNICODE supported?
  --------------------------------------------------------------------------------------------------------------------------
  
  Thank you for spending the time to read my questions and I hope to hear soon tips from you guys.
  Million thanks again for sharing.
  
  Best regards
  Noob, but eager to learn

  The requirement to always set NLS_LANG is not true for JDBC, which ignores the NLS_LANG altogether. Java programs extract the textual data in string variables, which uses Unicode UTF-16 by design. JDBC defines the conversion of character sets so that data is converted between UTF - 16 and the database or the national character set.

  The obligation to set NLS_LANG is not generally true for the OIC, either. The first call to a problem of the BEAK may be OCIEnvNlsCreate(). This call has two parameters that allow the caller to set the character set to use for the text of VARCHAR2/TANK/LONG/CLOB/statement and the character set to be used for NCHAR/NVARCHAR2/NCLOB. Only if these character sets is specified as 0, character set NLS_LANG is used. Also, the OIC programs can specify different character for each binding sets or set the variable (i.e. the buffer input/output). Note: The OIC programs always use NLS_LANG to initialize the language settings and the territory for the client program and the database session. Only the character set can be specified is OCIEnvNlsCreate().

  OCIEnvNlsCreate() can specify the client character set to UTF-16 (platform boutien) format. This is not possible with NLS_LANG.

  Various interfaces based on the BEAK, such as ODBC Oracle and .NET for the ODP, explicitly initialize OCI with character set Unicode and therefore ignore the NLS_LANG character set as well.

  Thnx,

• Collect and display data from several workstations

  Currently, the data in the CSV format locally on several workstations running Labview and the format of the recorded data is the same for each workstation. Data are recorded roughly every 2 minutes at each station and at different times.

  Computers of these stations are connected network but no saves a copy of their files CSV to the server that I know is not ideal, but a part of memory original.  What is now there that a computer on the network brings together these data by workstations and then the poster showing trends in workstations etc. in graphic format and possibly Excel.

  What I'm looking for is some advice on the best way forward.

  I looked at shared variables as a possible solution, but it is work stations send their respective data to the 'central' PC or this PC "questions" workstations that seems inefficient.

  Another thought was using Active X workstations to write in an Excel file running on the "central" PC

  Finally thought that workstations have record their findings to a server and then 'central' PC to access that data, it brings together and then displays the results combined.

  There are several things that remains to be clarified.

  • All LabVIEW programs, individual data record data in the same format and the same number of data points?
  • Record all programs of LabVIEW at exactly the samerate?
  • Are all data on a be saved in a single file of the Machine, or each reading (at intervals of 2 minutes) in a separate file?
  • You are trying to combine data from different machines such that it is collected or after the entire collection was done, and all files have been written?
  • Another that the timestamp of the data file, is there a "time stamp" in (all) the individual data files?
  • If you assume that the data of different machines are more synchronized, you have in mind a way to combine the different readings of the time?  What happens if they are sufficiently different that, say, the Machine has 20 readings more (because it started much earlier) than other PCs?
  • If the machines are not saving at the same rate, how will handle you that?

  A single method, you might consider is to write a program that works on any network connected PC, including a no participate in the recording of data.  For simplicity, assume that each machine "participatant" starts at around the same time, saves exactly at the same rate, written a single data file and has already closed.  If the program "Combining" knows where all data files (because he knows the name of each machine and the location of the file on each machine), it can open all the files, collect all the data and treat it but want to (including a 'combined Excel workbook"writing with a spreadsheet separate for each PC, or combining them all on one sheet).  Just decide what you want to do in the context of the issues raised above.

• transfer data from a database not AL32UTF8 (WE8ISO8859P1, US7ASCII, UTF8) to a db AL32UTF8 using dblinks

  Hello

  We had 3 databases off-production of the version 11.2.0.4 on AIX platform. These 3 databases had character set WE8ISO8859P1, US7ASCII & UTF8.

  We are migrating to AIX to the Linux platform and DB version will remain the same. New databases will have character set AL32UTF8.

  We had gone through various metalink notes related to conversion problems and possibly the character set. We understand that we need run the csscan utility to check

  all possible data issues and fixed before using export/import. We are trying to see if we can use DB link to copy data from db not AL32UTF8 AL32UTF8 DB.

  And we have not found any document mentioned that DB link can handle character set conversion and can use as an alternative to export/import.

  Our concern is that can we use DB links to copy data not AL32UTF8 db db AL32UTF8 after we deal with truncation and data loss?

  The DB has only English characters and symbols. There are sign euro no. European characters or Asian characters in db.

  Help, please.

  I've referenced below documents.

  Yes, you can use the links to the DB.  I doubt DB links are faster than Data Pump, but they perform character set conversion. Questions that you can meet the copy of data through DB links are basically the same, you may encounter using Data Pump or any other method of migration.

  One import thing to note: If you are using ETG over link DB (without specifying data types), columns of the semantics of length created on the target aura database bytes of length three times larger than the columns in the source constraints. You can run the CREATE TABLE AS SELECT INSERT followed instead.

  Thank you
