Reading/Writing Data from a SQL Database

Hi,
I have a data structure called 'Quote' which contains a number of different variables and controls ranging from text boxes, check boxes and radio buttons, i need to be able to read and write this from a database.
First I think a description of my overall project is needed:
Project Description
I have been given a brief that basically says: i have to create a programmed solution in VB to solve a problem. This problem can be anything we like, and I personally have chosen to create a program that manages quotes for building Log Cabins (this is very contrived and far from anything someone would do in the real world).
My solution will allow a generic user to create a quote (using a form with controls such as text boxes, check boxes, radio buttons) , and then save this to file. These users may then wish to load/edit this quote at a later date, from another form.
Whilst completing this project, i'll only have up to about 5 records (quotes) within the system, so i dont need the ability to store hundreds of records. And each record will be relatively short, with only about 10-15 data items within the data structure.
Also the Admin (or business owner in this case) need to be able to view all saved quotes in a presentable format, and edit them if needs be, from within this same program.
This solution does not need to be absolutely perfect and 100% efficiently coded, or have all the bells and whistles a real-world program would have. This is for an A level computing project by the way.
So basically, i need to be able to read from the database (to populate a Data Grid (i imagine this is best way?)) and so Admin can access any quote and edit it (editing is not vital, but viewing/printing is. Maybe i should stop at just viewing any quote?). Also i need generic users to be able to fill in the Edit Quote form and then save this data into the database.
And is a data structure really required for me to use a database?
I've never used databases in VB before (but have used them elsewhere, mainly Access) and so am completely new to this. Any help will be much appreciated.
Thanks

this is just a dataset i created using the dataset designer.
OK, so i have the dataset called "MyDataSet".
I also have the following variables:
Code Snippet
Dim FloorSpace As Int32
Dim NoOfBedrooms As Int32
Dim NoOfBathrooms As Int32
Dim EnSuites As Int32
Dim LuxKitchen As Boolean
Dim LuxCabin As Boolean
Dim Flooring As Boolean
Dim VoiceLighting As Boolean
Dim SolarPanels As Boolean
Dim IntegralSound As Boolean
Dim WindowFrames As String
Each of which relates directly to a column in the dataset (data type matches too).
What i need to do now, is to save these variables as an additional record in MyDataSet. And then save MyDataSet to file, so it can be loaded again next time the program is run and more additional records added. (all files are local by the way).
how would i go about this?

Transfering data from External SQL database to BW

Hi Experts,
 I am trying to extract data from an External SQL Database in BW using
 DB Connect.
 1. I have created a DB Source System.
 2. Using this Source System I have generated a Datasoure.
 ( following all the naming conventions for Table Names and Field Names)
 Till this point everything is OK.
 Then I assign a Infosource and try to upload the data into PSA.
 The process is never complete and I am getting a message
 Request still running
 Diagnosis
 No errors could be found. The current process has probably not finished yet.
 System response
 The ALE inbox of the SAP BW is identical to the ALE outbox of the source
 system
 and/or
 the maximum wait time for this request has not yet run out
 and/or
 the batch job in the source system has not yet ended.
 Current status
 No Idocs arrived from the source system.
 please help me.
thanks
arshad

please first tell me which wich user you connect and the exact name of your table/view: is it dbo.table?
as I said, better create a user in your SQL, log with this user and create a view.
in RSBDC select this view and generate datasource. Check if you see data.
if yes, the load shouldn't fail.
We came across the same issue: login with sa, accessing a dbo. object; seing the data in RSDBC but nothing loading...
let me know

Is it possible to migrate WebCenter Portal data from a SQL database to an Oracle database?

We have our WebCenter Portal applications set up using a SQL database. Now we're wanting to migrate to an Oracle database and I'm wondering if that is possible.

Yes it should be possible though i have not tried it myself. You basically export a file from mds ( xml) and import it into oracle db.
Thanks

Why is performance so slow reading binary data from a SQL Azure DB with EF6.x

I'm running a WPF client that hits a SQL Azure DB using EF 6.x. For the most part, everything seems to be working fine. The one exception is when I try to read a large binary column.
I am storing files in the DB as a binary column. When I test using the local DB, everything sings. When I switch to the Azure DB, I get timeouts when I try to read the file contents. I have no problem saving the binary data to the DB, just
reading it.
I don't know how to troubleshoot this. I looked at the Query Performance page in the Azure portal, but it doesn't time stamp anything in there and you can't clear it, so I can't correlate what's running with the queries that show up there.
I tried to start SQL profiler against the DB, but was denied because I'm not a member of the sysadmin fixed server role.
If I query for the data directly, it comes back quickly. So this seems to be an Azure via EF issue.
Any help is appreciated.
http://digitalcamel.blogspot.com/

Hi Digital Camel,
Since I don't know what your scenario is, I won't argue too much about not storing binaries in your SQL DB, but still: don't store binaries in your SQL DB :). The main reason is simple: first and foremost, in both the current and future pricing tier your
levels are defines on the size of the DB. Basically, you pay way more by storing your binaries on your SQL layer rathern than storing them elsewhere, such as Azure Storage. Second, the protocol your binaries would be downloaded over the wire is prone to network
connectivity issues: you could use HTTP(S) or FTP instead, if you'd use Azure Storage. Last but not least, when you download the binary from your DB, you keep a connection open which in the end is a connection other users might have used to query data instead.
However, in regard to your question, how did you "query for the data directly"? Did you try to query the data using SSMS with the Client Statistics option on? This could tell you if the problem is network, server or client related.
Hope this helps!

Reading data from Sybase SQL Anywhere 7 database to write into a SQL Server database

Hi,
I need to import data from a Sybase SQL Anywhere vers. 7 database. This RDBMS was used more 10-12 years ago. I want to write Sybase data into a SQL Server 2008 R2-2012 database. For testing purposes I'm using SQL Server 2005.
After that I've installed Sybase SQL Anywhere vers. 7 I can use the Adaptive Anywhere 7.0 ODBC. I'd like to use SSIS to import Sybase data, but I cannot create an OLE DB connection in a right manner while I can create and ODBC connection manager and so I
can use an Execute SQL task (and not a data flow task, unfortunately!).
Well, after using this Execute SQL task to read fe a table with thousands of data rows how can I write the entire data collection on a SQL Server table?
Thanks

JSP read and write data in MS-SQL database

I am new to JSP. I need to write JSP page to read and write data in MS-SQL Database. I wonder if it is different from other database. I couldn't find useful pointers in the web. Please advise. Thanks!!

Sure, SQL Server is different from Oracle is different from MySQL is different from...
But all of them can be accessed using JDBC:
http://java.sun.com/docs/books/tutorial/jdbc/
Maybe you should learn about that for starters.
You can use SQL tags from JSTL in your JSPs. I'd recommend JSTL highly. No scriptlet code that way. - MOD

How to reduce the run time of ABAP code (BADI) when it is reading huge data from BPC Cube and thus writing back huge data to the cube.

Hi All ,
In Case of reading huge amount of record from BPC Cube from BADI code , performing calculations and writing back huge amount of data into the cube , It takes lot of time . If there is any suggestion to read the data from Cube or writing data into the cube using some Parallel Processing methods , Then Please suggest .

Hi Gersh ,
If we have a specific server say 10.10.10.10 (abc.co.in) on which we are working, Then under RZ12 we make the following entry as :
LOGON GROUP          INSTANCE
parallel_generators        abc.co.in_10         ( Lets assume : The instance number is 10 )
Now in SM59 under ABAP Connections , I am giving the following technical settings:
TARGET HOST          abc.co.in
IP address                  10.10.10.10
Instance number          10
Now if we have a scenario of load balancing servers with following server details (with all servers on different instance numbers ) :
10.10.10.11
10.10.10.13
10.1010.10
10.10.10.15
In this case how can we make the RZ12 settings and SM59 settings such that we don't have to hardcode any IP Address.
If the request is redirected to 10.10.10.11 and not to 10.10.10.10 , in that case how will the settings be.
I have raised this question on the below thread :
How to configure RZ12 and SM59 ABAP connection settings when we have work with Load Balancing servers rather than a specific server .

APEX Application accessing data from two different databases

Hi All,
Currently as we all know that APEX Application resides in database and is connected to the schema of that database.
I want APEX Application to be running and accessing data from two different databases. Elaborating my question,
Currently, my APEX Production Application is connected with XXXX Schema of DB1 Database(Where APEX Resides). Now I want to add some pages into this APEX Application for REPORT Purpose, But I want to connect this REPORT APEX Pages to get data from Different Schema YYYY for Database DB2.
Is it possible to configure this scenario?
The reason for doing this is to avoid the REPORT related (adhoc queries) resource utilization effect on Production DB1 Database.
Thanks
Nil

1. If you do the joining of two or more tables in DB1 then all data is pulled over to DB1 and then the join is executed: so more data over the databaselink and more work for DB1. Better keep the joining stuff where the data resides and just pull exactly that data over that you need.
2. Don't know about your different block sizes. Seems a nice question for one of the other forums (DBA or SQL).
3. I mean create synonyms on DB1 for reports VIEWS in DB2.
Hope all is clear!

How can i save the data from the Oracle database to my local directory

How can i save the data from the Oracle database to my local directory instead Of saving the data file to the Directory created on the Oracle Server ?
I require to design the Procedure which will pull the data from various tables and needs to store the data in the Client's local directory.

Since SQL*PLUS runs on the client, you can use SQL*PLUS to spool data to your local drive.
You could also use the database to write a a specified drive where all users have access to (mapped network drive, e.g.). I wouldn't recommend doing it that way, but it is sometimes useful when the files are created in some nightly batch run.

Populate a table reading the data from a TXT file

how can I populate a table reading the data from a TXT file?
thanks

Hey Kevin!
Using FORMS.TEXT_IO to bulk load data from a file strikes me as re-inventing the wheel. It is just about justifiable in a self-service environment, but I regard the EXTERNAL TABLE is a better solution for that situation as well.
The same applies to UTL_FILE. I think the ability to read text with UTL_FILE is primarily intended for read file-based configuration or file manipulation/processing rather than data loading.
Re-writing a text file into SQL statements is too much like hard work (even with an editor that supports macro definition and regular expressions) for no real benefit. You lose all the bulk load peformance you would get from SQL*Loader. But for QAD I'd probably let you off with it.
You missed out one obvious alternative: using Java to turn the contents of an XML file into a CLOB and inserting it into a table which is read by a PL/SQL procedure that parses the XML records and insert the retrieved data into a table.
Stay lucky, APC

Query data from MS SQL db through Oracle ? By using JAVA ?

Hi folks,
I would like to sync our one table in oracle db with table in different system, stored in MS SQL database.
What would be the easiest option for connection from Oracle to MS SQL db to be able to query data from MS SQL through some Oracle package?
If possible, I would like to keep all "tricky steps" within Oracle database. I heard about option with Java, but so far we have no experience with java in Oracle.
Our database: Oracle 11g Database Standard Edition One

How to replicate data from MS SQL Server to Oracle

Hi,
Can someone please help me on how to replicate data from MS SQL Server to Oracle 8i database.

Dear,
I'm a student.
I do simple replication on Oracle 8.0.5 successfully. (one master site and one snapshot site). I only use the SQL*Plus and Schema Manager to do.
But when I do advance replication (multimaster replication) I meet many problem. So I don't get the result.
Do you show me the technology to do that ?
Thanks !

Display images from a SQL database

I want to display images from a SQL database. The images are in a table under a specific column and are stored as a link to the image. How would I display the images from the column in LabVIEW?
I'm using LabVIEW 2013 version 13 and SQL Server 2012
Paul Power
I have not lost my mind, it's backed up on a disk somewhere

Hi PauldePaor,
I hope you are well.
Once you have pulled the data from the database into LabVIEW in a string form (or path), you can simply use the Read BMP File (Or jpg, png depending on the file type) VI.
