• Insert XML data into the MySQL database

  Hi all, I'm new with XML and I need help with the insertion of XML data in the mysql database using coldfusion. I looked on the Coldfusion Documentation and saw how to convert XML to a Coldfusion query... but there was no example of how to do an insert. If anyone can give me a good example or point me towards a good direction on how to do it, I would really appreciate it.
  
  Thank you very much in advance

• Insert data in mysql database

  Hello world

  I searched all over the internet for solutions to my problems, but it is not easy to find good explanations of how things work with databases.

  So, here's the situation:

  I had a (built with LC designer 8.0) form with a button of HTTPsubmit linked to a php script which would address all communications to my mySQL database. Everything works very well for that.

  now, I have a second form and wanted to do the same. But on this new form, I have a few paintings repeated data with the same name (each row has the same nodes), and the HTTP POST method will give me only one of the data. I could change the name of each node to make it unique, but 1. It takes some time and 2. It is not a very clean solution

  So, I tried to set up the famous "DataConnection" I've tried to avoid in the first instance. I've successfully installed mySQL ODBC connector and communication between the form and the database is perfectly fine. But I understand that, in the 'method' of DataConnection each field of the form corresponds to a field in the database. While I would like to insert a new section of mySQL for each line of my paintings.

  This is where I am stuck. I thought of two methods:

  1. I am a newbie with DataConnection so maybe there's a way to do what I want, but I don't know. Ideally, I guess something like this: "OK, there is good communication with the mySQL database. When I click on the "submit" button, move forward with javascript code that collects information from the form and gives a request for INSERTION in the mySQLdatabase; "and that for each row in the table. Collection of information is no problem, but how should I handle these multiple query "INSERT"?

  2. perhaps, it is also a way to change the submit button, so that the data is sent to a php server side or a js script, but instead of having urlencoded method or the HTTP POST method, send the code over XML data and the script will deal with it. In fact, I know that this change is possible; but I have no idea on how to manage the data from the form, if this isn't HTTP POST (or GET). If I choose a shipment to a php script, and I send XML or XDP, what is sent to the script?

  Well, thank you in advance if I finally find a solution!

  tguiot.

  OK nevermind, I found the solution with an appropriate method. Here is the link where I found what I needed: http://blogs.adobe.com/formbuilder/2006/12/databases_ins_upd_del.html

  That's exactly what I planned to do, but it is indeed a more advanced manipulation of the database connection object. Here's the idea:

  • create a DataConnection to your database, using the standard method (in my case, using the mySQL ODBC connector)
  • create a copy of the DataConnection object and clean it (to remove all unnecessary nodes)
  • Change the value of thenode of your sql string
  • Run the SQL with the method 'Open'

  in the link provided, you will find the pdf file to open it with livecycle designer. There is a "Database" variable which contains the functions, and the code is commented pretty precisely.

  All I now need to do is navigate in my table and execute an insert sql for each line.

  So good to finally have a solution!

  Thanks anyway for your help pguerett.

• Insert a date in the MySQL database

  I have a problem to enter a date in my database using Dreamweaver.
  I enter the current date in a session variable. It seems OK; When I echo the date, is correct.
  Then I get the date in the database (see attached programme).
  At run time, there is no error message.
  But when I display the date using PHPMyAdmin, the date is set to zero.
  I don't understand.
  Could someone help me?
  Thank you.
  

  Thank you.
  I found the solution.
  To be inserted into a MySQL database, the date format must be A-m-j.
  It was my mistake.
  Kind regards.

• Using mysql embedded database fault to purge data

  I'm running foglight 5.6.3 and uses the embedded mysql database.  Currently, we become low on storage and I want to be able to serve data.  The baseline_profile table has more than 14 million lines.  Is it possible to purge certain data in addition to retention strategies?  Thanks for your suggestions.

  Hello

  What is your political conservation as default? Is there a purge statement? Is storageconfig.xml the default?

  Check tables that are larger to avoid some known bugs (such as the registry or persistable_config table) - basic lines also accumulate cruft I believe, Dmitri sounds on what exactly I'm sure.

• shared object why? If you already have all the data in a mysql database

  Hello.

  I see that a shraed object can be used to store the data locally is to say: what avatar you use, what level you are and what the screen you are currently on. But why you need or use a shared if object you all this info on a mysql database, anyway.

  In addition, a shared object can get destroyed as you clear the cache, as many people have. In addition, Governments are looking at the cookies and they start to hang.

  That is to say: should really so we have?

  I quite often to store a user name in a shared object and pre-fill the login form

  most of the browsers that will be for text html in any case boxes

  you could add an option "Remember me on this computer" connect directly, and then you would save username and password

  your site might only need to login to some privelidges, like posting in a forum. You may want to save the preferences for the shared object if they are applied before the opening of the session

  BTW, the shared object is not a cookie. clear cookies, cache and browser history make the shared object. In fact I bet that most of the users don't know how to delete it.

• Why convert? What is the advantage? Why convert it before you send the data over the network?

  Hello everyone.

  I have a question quite simple and intuitive. Yet Google does not seam to get the answer.

  Basically, I'm curious why should we catalogued something? It seems to me that it's just a little like a "band-aid" for editing data in conversion to a new data type, when it is not properly declared with an appropriate data type. What would be the advantage of this?

  Furthermore, I see a lot of data type casting to U8 programs before sending it over the network. Various reviews say it's for speed, but I can't understand how it improves speed. The same amount of data is still sent, just in a different type of data. This is overcoming a limitation of the network. The network somehow send smaller data types faster?

  I've been curious about this for a while and have yet to find an answer. Any help is appreciated.

  Thank you

  It really depends on the specific situations.

  For example, some functions explicitly require certain types of data as inputs if they are not polymorphic.

  This means that if you do not convert the data yourself and you will see a red dot forced LabVIEW will do it for you.

  As to why the data was not the correct data type in the first place, it is sometimes inevitable.

  A few examples

  -What happens if you just read a text file as a long string.

  If there is digital data in this file, you need to analyze, and then convert it to a usable type (int, sgl, dbl, etc.)

  -you are given a 3rd part VI, dll, etc. that returns a numeric value as a double, but you need the value to I8.

  You cannot change the output of the function given to you, so what you can do to remedy this situation is cataloged data.

  Somehow, this is my first response, but in a more general sense.

  Many functions down to the level of the OS run in binary.

  If your data are not already in binary, the sending computer must convert it to binary, and then send it, have the receiving computer convert in return.

  Two conversions on each side of the transmission add unnecessary delays.

• Link from Oracle to MySQL database select only one line

  Hello

  I created a connection to the batabase Oracle 11.2 to a MySQL database via a database link. The following statement shows that 35 lines are in the mySQL table:

  Hello
  The error in your gateway trace file-

  [Microsoft] [ODBC driver manager] Nome da dados nao e found melting nenhum driver padrão especificado {IM002}

  translates-

  Data Source name not found and no driver by default specified

  This means that you don't have a system DSN defined on the Windows machine called "ms", which uses a MySQL ODBC driver to connect to the MySQL database on your Linux machine.
  The system DSN to be used is defined by the parameter-

  HS_FDS_CONNECT_INFO = ms

  Therefore, you must perform the following operations

  -install a driver Windows ODBC de MySQL
  -define a DSN system whichuses this driver to connect to your MYSQL Linux
  -Use this DSN as parameter HS_FDS_CONNECT_INFO

  You must ensure that the DSN can connect to MYSQL without Oracle involved before DG4ODBC can also establish a connection.

  Kind regards

• fixing mysql database

  I have an old database that came from MS SQL and was imported long ago to mysql. He seems to have a few bad dates I need to fix...

  Some appear in the format:

  0000-00-00 00:00:00

  error in cf research says:

  cannot be represented as a java.sql.Timestamp

  (I think they speak of this area...)

  It makes it difficult to update the PB when it keeps the slightest mistake...

  also I tried to look with phpmyadmin in the field for: AS and 0000

  but empty shows query

  I've noticed that most recent TS seem to have additional one.0 in the end as:

  0000-00-00 00:00:00 = old problem?

  2012-10-01 00:00:00.0 = new ok...

  Q: How can I get around this?

  It is a well known problem in older versions of MySQL. A common solution is to include the property

  zeroDateTimeBehavior = convertToNull

  in the field of connection string in the source settings in the ColdFusion Administrator of MySQL database. Requests and then returns the value NULL in the 0000-00-00 00:00:00 as is encountered. See, for example, the Nadel's blog on this.

• continious streaming to the mysql database

  Hello

  I have LabvVIEW and LV Database Connectivity Toolkit. I'm creating a test sequence and I need to log the results and data to a mysql database. I want to ask you your opinion on what will be the most effective approach to connect to the database. I'll open connection once and then permanently in the stream of data to the database and then once I am finished, I've just will close the connection (similar to the concept of IO file in LabVIEW. Or will I open connection every time I need to connect to the database and immediately close and then open it again once I need to save the data again. SO basically, my program flow will be:

  1. opening (operator or engineer)---> this information must be connected.

  2. Select the test---> name sequence selected sequence must be connected

  3. start Test---> uut data number of series, and the result must be connected

  and so on.

  so the cycle just repeats, it may be that the operator will continue to another sequence of test, or switch to another object to measure. But all the information will be saved to the database.

  So, what will be the most effective approach of data communication? It is best to open the connection before, connect and then log the data on the fly, and then after the operator made with test, to stop the program, the connection will also be closed.

  or

  Whenever I need to connect to the database, I'll open the connection, and then close the log data (i.e. for the Login of the operator, the database connection will be opened, save the id of the operator, then closes the connection, then when a test sequence is selected, the database connection is open again and then save the name of the test sequence) and then close the connection, etc.)

  This will be my first to deal with the database and I don't know if the approach to database is the same as the approach to connect to the file using binary or text. I know that for the binary or text, it is recommended that we make data streaming, but for the database, it will follow the same concept? My concern is that these tests can last for hours. I'm not sure how stable it is to keep in now open database connection.

  Any help or opnion anywone, will be very happy. Thanks a lot in advcance!

  I think both architectures are good. Choose the best one depends on too many factors. How many connection you have simultaneously to this base? How is the load of your LAN network? How long can happen that you lost the connection with the database? The amount of data you want to transfer for each transaction?

  According to me, a third approach now is to connect the the test data for the local machine and transfer the data at the end of the trial. It is an approach to security that it is also proposed by Microsoft using the ADO SqlServer 8.Lorsque. The data group are indeed a copy of the data on the local, but I think that it is better to save data to a log file and once the acquisition is completed, transfer them to SQLServer and then kill the file.

• Convert the database to 10 v to v11

  Hello

  I'm unable to convert and merge a v10.1 v11 user database.  I made a backup of Usrcomp_S.usr to another folder in Windows then used the merger of Multisim and Ultiboard and conversion tools. Here are the steps I followed:

  1 tools > Database > convert database...

  2. Select Source in the dialog context database names.

  3. navigate to the database using the Windows dialog box. Select my copy of database using "All Files." Curiously he is not using the default filter. Select OK and then the following error:

  The path of the database: "database\UsrComp_S.usr" was not found or not set.
  You want to select the path where the database of component?

  4. Select Yes then select my now visible database of the dialog Windows.

  5. press start to convert my database to aid auto rename. Briefly, something happens that seems to be the conversion and the window convert watch Done

  6. close the convert and open tools > database > merge a database...

  7. Select a name of the component database

  8. Repeat step 3 above. The allegedly converted database is still not visible but this time there is no option to "All Files." In the file name drop-down box I choose the path previously used for the database copy. Select open and receive the following error message:

  The path of the database: "database\UsrComp_S.usr" was not found or not set.
  You want to select the path where the database of component?

  9. Select Yes then select my now visible database of the dialog Windows.

  10. press on open and receive the following error message:

  Error: Could not open the database [user data].
  The file format/version does not, and cannot be merged.
  If the database is from a previous version, use convert the database.

  Help, please. This should be a simple process of a button to import parts of the user of a previous version.

  Hi Richard,

  I think you are trying to convert the incorrect database. From the name you specified (Usrcomp_S.usr), it's just a CDS model uses to create a user database, it is not your user database.

  On Windows XP, the user database is located in C:\Documents and Settings\\Application Data\National Instruments\Circuit Design Suite\11.0\database\

  On Windows Vista/7, the user database is located in C:\Users\\AppData\Roaming\National Instruments\11.0\database\

• How or there is no model code keep update/sync the local database indexedDB for MySQL database online?

  How or there is no model code keep update/sync the local database indexedDB for MySQL database online?

  Unfortunately there is no direct connector for an application of WebWorks to a back-end database. You will need to do, is to have some middleware web server (Apache, Node.js, etc.) who manages a web service that you can make an HTTP request to and GET, POST, UPDATE, DELETE data. Middleware and then transmits commands to the back-end database and returns the results to the finished device.

• REST API - the field value date Contact exported in digital format.

  Hi people,

  I used below REST API to retrieve the Contacts with the views and custom filter.

  The JSON response, I shot the date value in the number format. As 'C_Lead_Score_Date': '1434456862',

  
  

  https://secure.Eloqua.com/API/rest/1.0/data/contact/view/ {identifier} / contacts/filter / {id}

  
  

  How can I convert the appropriate number in date value? or y at - it an adjustment to the level of the code to retrieve the value in the correct date format.

  
  

  The data type of the field is dates.

  The date is returned to as a Unix timestamp.

  You can use an online converter to convert it to a normal value, for example: online - time conversion Conversion Unix

  1434456862 = Tuesday, June 16, 2015 12:14:22 GMT

• Database is configured for Data Guard

  I'm lance a UTF8 conversion on a development database, which has been cloned from Data Guard. There is a warning in the Migration status: "database is configured for Data Guard" which is looking at DMU to determine this? The database is opened in read-write mode and it behaves like a primary database (I have the MISP scanner and run updates to address representations not valid). I would like to know what I need to update the settings.

  This prevent me to convert tables using DEC? When I try to select this option for all tables I get the message, "CDS does not support conversion method"Copy data using CREATE TABLE AS SELECT"for tables that are involved in a process like capture Oracle Streams, or apply.". Another method of conversion available for the table.

  Thank you

  Ben

  CDS checks if the DG_BROKER_START parameter is set to true.

  The problem with the ETG is independent of the Data Guard. The CDS is true for tables which:

  -are asynchronous stream capture source, or

  -update conflict managers have, or

  -DML managers have, or

  -conflict resolution settings have

  The above tables are considered to be configured for Oracle Streams and are not supported by the method of conversion of DEC. This is because the DEC method creates a copy converted the table and falls from the original. The CDS is not able to move the configuration information from the old table to the new flow.

  Thank you
