I have an oracle database. I connected to the database with odac (ODP.NET) and in query window I made an easy test:
select * from abc.groups;
after I check this in Toad for Oracle.
The query window contains 192 record, and the toad contains 352 records.
I tried to find some special lines, for example:
select*from abc.groups where id=15;
I couldn't find anything in query window, but I found it in toad.
There is a same database, same log in details.
In C# the date handling is not always correct where is the problem?

I have this plugin to connect xamarin form with sqlite: SQLITE PCL
If I query the database with a few tables records it´s works correctly, but if I query tables with for example 29000 records, it starts looking for a good time and returns no data, but If I put limit 100 to the same query it works correclty.
I think the solution would be something similar like connect timeout in web forms, but I don´t know how to do this with xamarin, how can I do this?
I do the same steps like in this page to connection:
LINK TO CONNECTION SQLITE
I accept suggestions, thanks.
I am using a SQL Server Compact database for a project I am working on and have been having a hard time trying to insert data to the database.
My insert statement and everything is working fine and data gets inserted too and I can even do searches for the inserted data (while in the application).
The problem I am having is when I quit and re-run the application, it seems that the data was not inserted into the database and the tables are empty too.
Can anyone let me know where I am going wrong with this?
Thanks
Could it be that the SDF file is overwritten with an empty version whenever you rebuild/run the application?
As Thorsten pointed out, check the Build Action on your SDF file.
I am having the following problem. I am creating a C# windows Forms application with which i want to transfer the data from a SQL Server to MySQL. The problem is that the data in the SQL is in latin and when i trasfer it in the MySQL DB it is shown like "?". Please give me some advice. I have tried to convet it but it does not work!
thanks in advance!
How are you selecting the data - using a sproc or sql command?
You can put a collate in the query (see : MySql Manual Ref) and force the correct collation back to your app (if reading from MySql or MS SQL both support it). This is easier than trying to convert (which does not always work as character sets are different sizes) or changing the db charset/collation.
I am working on Windows Forms Application with SQL Server Database. Now I have to convert the SQL Database to MS Access database as per the requirement. Can any one help me out
how to convert SQL database to MS access database so that, I can access the same tables.
Thanks & Regards,
Vani.
You can use MS SQL management studio to export tables data and structure to access. To do this right click on you db in Management studio and select Tasks -> Export data. Now follow the steps of the wizard. First you'll select the source - it would be you db, next destination - it would be an access file. And there you go :) Have fun!
As Elastep says, you can export data from MS SQL Management Studio - but that will only get you to .MDB-files; ie. prior to Access 2007. The steps below works both for 2007 and prior (although the actual path to execute them may vary in the different versions):
In Access you can import the tables from SQL Server - when in your target database in Access, choose External Data --> More --> ODBC Database. In there you can set up a connection to the SQL Server and choose between Import the source data and Link to the datasource. After selecting either, you can choose the tables you wish to import/link.
If you import, the data will be copied physically to the Access-file. It sounds like this is what you want to achieve.
However, as comments above suggest, this sounds off. Are you sure you want to move your data to a weaker engine? If you do want to keep the data in the SQL Server, whilst using Access only for forms, etc. you can link the tables instead. This way, you can use the rapid-prototyping, datacentric tools in Access, while keeping the security, consistency and scalability of the SQL Server.
For reference, you might want to take a look at this: http://office.microsoft.com/en-us/access-help/import-or-link-to-sql-server-data-HA010200494.aspx
Wrote a Truck show Contest voting app, financial etc using sqlite. decided to write backup app for show day using ce 3.5. Created db moved to data directory, created tables configured dgridviews all is well. Entered some test data started management studio 08 ran select query against table and got null returns. Started app from vs studio and found that test data is gone. Re entered data ran query in MS data gone again.
If I use VS Studio can start and enter data, close app restart and data is still there, seems only when using outside tool on select query data deletes.
I don't know CE that well but this cannot be right.
select * from votes = delete * from votes??????????????
You're probably overwriting the database during your build.
