• Difference between Oracle database and SQL or SQL Developer +?

  Hello
  I am very very new to Oracle... Only yesterday I installed Oracle 11 G for learing... I found to create an Oracle database
  
  Oracle Db11gHome1 = > Configuration and Migration Tools = > Database Configuration Wizard
  ... blah... blah... blah... Success... I created...
  
  But I found the menus
  
  Oracle Db11gHome1 = > application development = > SQL Developer
  Oracle Db11gHome1 = > = application development > SQL Plus
  
  And so I get confused... I know SQLSERVER 2008... etc... to create databases... So the above said two is for what purpose?
  Anyone can show me a route for this spirit of quarrels?
  
  Thank you

  Hello

  Welcome to the world of Oracle.

  SQL Developer: http://www.oracle.com/technetwork/developer-tools/sql-developer/what-is-sqldev-093866.html

  SQl more: http://docs.oracle.com/cd/B13789_01/server.101/b12170/qstart.htm

  These docs will give an initial advance for these tools.

  Something in common between these two tools is: both are used to access the Oracle database.

• How to determine the number of rows in the database and save the result to a local variable?

  Hello

  I'm a newbie in the use of TestStand, databases and SQL, and now I've met difficulties. I use TestStand 2014 (32 bit).

  I have a need to know the number of rows in a database and save that number in a local variable. I tried to practice using the database of the Types of step provided with TS. I tried to use the following in a SQL statement:

  Locals.NumberOfRows = ("SELECT COUNT (*) FROM TEST_TABLE")

  It returns an error: specified value is not the expected type. My goal is possible in this way, or I'm doing this completely wrong?

  -RautSa

  Thank you for your response, Norbert. I have a database of who wins new values at random, and sometimes I need the exact number of rows in this table.

  I managed to achieve my goal by using the SQL statement: "SELECT COUNT (*) as Rowcount OF TEST_TABLE", followed by a data GET operation, which records that number of lines in a local variable.

• How to send the SQL for SQL Server statement and return data without using database connectivity Kit?

  Hi, I tried to figure out how to extract data from my SQL Server databases and reading messages and to do some tests with examples, I can get data connection type in my SQL server, but so far nothing helps.  Is it possible to get data from a SQL Server database without using the database connectivity Toolkit?  and if so, how?  are there whitepapers and/or examples of this?  So far, I can't find something that works.  Thank you.

  Jesse - what is your reason for not using the database connectivity Toolkit? It is by far the best way to recover the data.

• MS SQL and store data on changes

  Hello

  I have sql server and sql database. I use connectivity tools and DB tools, to open, write... on this database...

  I want to know where I can put that will store my data only on change? Suspicion, advice?

  Thank you

  Notification of changes in the database depends on the database you are using and the version that you are using the specific provider that you use. With SQL Server 2008, you can add triggers to tables, as discussed here: http://msdn.microsoft.com/en-us/library/bb726006.aspx. There is also the SqlDependency (.NET) class.

  Your question is really more a question of data rather than a question of LabVIEW, then perhaps that you will gain more traction by posting in one of the SQL forums, or by doing a search on stackoverflow.com.

  In addition, be aware that you posted your message on a Sunday. This forum is mainly composed of volunteers. A little patience is appreciated.

• In general, is it better to use java.sql.Date and java.sql.Timestamp instead of oracle.jbo.domain.Date?

  Hello world

  During playback of Oracle ADF Real World Developer's Guide, I noticed the dates match occurring in JDeveloper is different from what is the list in the book. JDeveloper is failing to oracle.jbo.domain.Date, but according to the book:

  DATE	java.sql.Date	DATE type is mapped to java.sql.Date if the column in the table is a no time didn't need information zone.
  DATE	java.sql.Timestamp	DATE type is mapped to java.sql.Timestamp if the column in the table has a component "time" and that the client needs to zone information.
  TIMESTAMP	java.sql.Timestamp	The TIMESTAMP type is mapped to java.sql.Timestamp if nanosecond precision is used in the database.

  In general, is it better to use java.sql.Date and java.sql.Timestamp instead of oracle.jbo.domain.Date? Using java.sql.Date and java.sql.Timestamp could save me some headaches conversion date. And, is there a place in JDeveloper to display these maps? I looked around and didn't see anything.

  Thank you.

  James

  User, what version of jdev we are talking about?

  In GR 11, 1 material versions db types date and timestamp are mapped to types of domain data that represents a wrapper for the native data types. The reason was that the framework can work with the domain types regardless of the underlying data type.

  Since Oracle 11 GR 2 maps the types DB to java types (default selection, you can change it when you create a model project, you can set the Data Type Mapping). Once the pilot has business components define you cannot change this setting it would break existing components such as eo or vo.

  So if you are working wit 11 GR 1 subject, you must use the domain types, if you work with GR 11, 2 or 12 c, you can use the domain types, but it is recommended to use the java type mapping.

• Installation of Oracle and SQL Developer data

  Hi, I was looking for some help/advice with regard to the installation of an SQL Developer and Oracle database on a 32-bit Windows 7 computer. I have been asked to create a database to store the data that I create through reports in Excel format, so I'm required to create a local database but do not know how to do this. Also do not know if I install the Express edition or Oracle 11 g R2 database. If someone could please advise on how I can get this has begun or even links/tutorials that guide me in getting this installed with a localhost.

  Thanks in advanc.

  Thanks guys, I managed to install Oracle 11 g 2 and I installed a database using dbca tool and I can connect to my database. One thing I noticed is that when I look in my tables in sql developer I see plenty of tables different i.e. def$ _, logmnr_, etc. and I don't know why did I expect an empty table.

  Thank you for all your help btw.

  One of the fundamentals of relational databases is that they use their own facilities to manage themselves.  This means that the database management system uses the database to manage data on the database using exactly the same facilities (tablespaces, tables, user accounts, procedures, etc.) that an application uses to store application data. See "data dictionary" so there is no such thing as a completely database empty.

  As said by others, you do NOT want to create your own tables under patterns oracle (users) or in the disc spaces logics own oracle (esp. SYSTEM and SYSAUX).  Create your own account user/schema.  Create your own tablespace. Do this by default tablespace for the user.

• Database and data source in the planning application

  Hi the Hyperion gods.
  In the process of creating, planning an application and create the data source, I'm a bit confused.
  Creating data source, it must give a name for the DATA SOURCE and a DESCRIPTION, and under the APPLICATION of DATA base, we need to specify things such as - platform DATABASE, SERVERNAME, PORT, database, USER and PASSWORD.
  I was wondering if someone could give me a good idea about the difference between the DATA source and DATABASE in this context.
  Since I am migrating the entire application and the structure of the cube from one server to another, do I need to appoint exactly the same (except for the name of the server)?
  Thanks for your comments.

  a data source is just a name for your connection information to the relational database and essbase who will use your planning application, I usually keep the data source name that is identical to the name of the application so do not become confused.
  Database platform is the type of database, for example, Oracle, SQL Server, the server name is the hostname for the relational database, data is the name of the relational database, I think the rest should be pretty obvious, but if you want more detailed information have a read of http://docs.oracle.com/cd/E17236_01/epm.1112/hp_admin_11122/app_dsc.html

  See you soon

• Number of databases such as Oracle and SQL Server in the same application ADF

  Hello
  
  In my application, I need to use two different databases such as Oracle and SQL Server. There are screens that I need to develop in the ADF where I need to involve fields of the tables in these two different databases. I just want to know - is it possible to do so in application of the ADF?
  
  Or to create a sort of link between these databases in the backend? Then create a view object involving some distributed SQL queries. What can I do with this type of request than anything? I mean, can I use the two insert or update operation using this VO?
  
  Or y at - it another way to do this?
  
  Please help, help here would be really appreciated. I've been stuck with this problem for a while now. I did search our forums for the same problem, but was not able to find a reliable solution.
  
  Thank you
  Vijay

  It's still not clear to me if you need two db tables in a query, or a transaction.
  If this is the case, your best option (to my knowledge) is to use a db link. in this way, you only need to access (for example the oracle db) and can access the objects from the other data from the oracle database.
  I don't understand

  (3) a model project with a meeting of the two datasource. I selected a data source and created OT and VO. When I have selected a different data source and select tables to create VO and EO and finished but these EO and VO is displayed in project. >

  (2) If you need to link data from these two dbs you can not use this approach (see the note at the top of the post)

• Data loss Virtual Center Database migration sql 2000 2005

  Hi, (sorry for my bad English)

  I moved the db installation remote sql 2000 Server remote sql 2005. I basically followed these steps:

  To migrate a database from the server vCenter 2.5 of SQL Server 2000 to SQL Server 2005:

  1. stop the vCenter Server service.

  2. stop the vCenter on SQL Server 2000 database.

  3 take a backup full database vCenter.

  4 copy the backup of the database to SQL Server 2005 host.

  5. create a new database on SQL Server 2005.

  6. restore the backup SQL 2000 vCenter database to the newly created database.

  7 correct permissions (same account, same password) see KB6565318

  8 native ODBC SQL connection change

  9. perform a change/repair Panel vCenter & gt; Add/Remove programs.

  10 in the Repair Wizard, I select custom and choose the newly created in SQL Server 2005 database.

  11 the authentication type used on SQL 2005 is the same as that used on SQL 2000.

  the license screen has an option box that says "I want to evaluate the product first," Setup does not correctly recognize the previous VirtualCenter database. » ???

  Now I can access the BDD via ODBC, and I am able to start the VC service. However, when I opened the client - I SEE NOTHING. Everything is gone. Totally empty. The data is still there well. I can go in sql 2005 and open the tables and see my hosts and virtual machines listed.

  Help, please.

  Thank you!

  I think that really there is a permission problem, but I'm not only deeply in SQL servers.

  Did you check for orphaned users?

  The permissions that are defined for the database of RESUMES?

• Problem with the two EA DEVELOPER SQL DATA MODELING 3.0.0.665 and 3.1

  I created a model of very large data using SQL Developer data 3.0.0.665 and 3.1 EA maker. Its having a lot of check constraints. Whenever I am the design of the fence and the DOF and reopening export to import the DDL file failure to import completely check constraints. It is important to check constraints, but without any range of values inside. Its very frustrating because whenever you open import ddl, you must manually add again all the details of data check range constraint.

  Please help me soon.

  Hi John,.

  Every time I'm fence design and export the ddl and reopening through the import of the DDL file

  Why are you doing this? Once the DDL file is imported and then save the drawing and open simply saved design, no need to generate the DDL and import it every time that you start Modeler data.
  On the list of values - forced as this CHECK (Active_Flag IN ('A', 'I')) are imported as constraint check plain and not as a list of values.
  There are the more specific elements import of check constraint - they are defined as type database constraint that you select during the import. Accordingly if you import your DOF as Oracle 10 g DDL, then you will get forced correct check in DDL generated for Oracle 10 g and Oracle 11 g. Constraint of evil will be generated for Oracle 9i. You can move the constraint for Oracle 9i (in the check constraint dialog box) or generic if it can be treated as such constraint.

  I logged for DOF bad bug.

• Creation of a new database Oracle and Sql Developer

  Hello
  
  I am a newbie to Oracle and and a beginner not so Sql Server and Visual Studio.
  
  I am trying to learn Oracle on my local machine. I want to create a new Oracle database and start learning from here.
  
  I downloaded the Client Oracle sql developer and maker of data. Could someone please provide some guidance on how to create an Oracle database?
  
  From the responses, it seems that none of the articles I've mentioned actually creates a database. SQL Server provides a free download, also a developer version for a small fee. What specific Oracle product would be better to provide this type of service?
  
  Thank you

  You can download the company for educational use via the OTN site. There is also the Express edition, which includes limits on the OTN site as well.

  Whatever it is, read the agreements to make sure that you use it properly.

  To know the size of the scheme: -.

  select owner,sum(bytes/1024/1024)MB from dba_segments group by owner;
  

  TO know the actual size of the database

  select sum(bytes/1024/1024/1024) Actual_size_gb from dba_segments

• HP 50g and StreamSmart 410 Data Logger

  No one knows for sure if the 410 StreamSmart data logger works with the HP 50 G. All the places I've read says that it works with HP 40 gs/gs 39. However, the guys of Educalc (http://www.educalc.net/1518486.page) says that it works with HP 50 g but I was not able to confirm. Anyone who has ever tried? If this does not work with HP 50 G, a data recorder that works with it?

  Thank you

  I don't think that the ROM with the support of the 50g never goes out publicly. However, they could have gotten ahold of it from somewhere, and that's why they say that it is supported. He is there not much of interest using the 50g to connect it upward and therefore only Roma to 39/40 were fully tested and released.

  The internal hardware between the ss400 and ss410 is totally different. Unfortunately, there wasn't enough space for two support units 1 rom version...
