hope someone can provide some insights or experience in this area.
I am currently building some reports in Power BI, the data source is connected via ODBC to a firebird database (testing environment atm). I copied the script to SQL statement and it runs ok.
However, something went wrong every time I refreshed the data, it stops at 'loading data to model' stage. I have to end Power BI in task manager then restart it again.
I don't know why this happens.
Thanks in advance.

I'm using Pentaho CE for general reporting.
We are running reports using the build In Report Viewer.
We've noticed that each report created using Report Designer and using KTR as data source executes transformate twice ... (as seen in logs)
For large, complicated KTRs with SQL queries this is an overkill.
Does anyone know what is the purpose of this ? How can this be changed ? or just give me some light on the subject ?
Thanks, help much appreciated.
I need to change the sql query used to pull data from a customer's database on an already existing report but they dont have crystal reports installed on their sql server.
I have a copy of their data on my local machine and can make the change and test it with no problems, but when I upload the report back onto their sql server, it complains that it can't find the database (unsuprisingly, as I've had to change the connection in the report to use the copy of their data on my machine!)
What I need to know is how I'm able to edit the sql query used on the report on my machine and have it retain the database connection that's used on the report somehow?
The change i need to make on the report is a bit more complicated than changing links in the database expert in crystal, its a change to the sql query used to pull the data from the database.
thanks, any help is appreciated, i'm fairly new to crystal reports so apologies if this is a simple fix.
You can change the SQL offline if you are using a command. If you are using database expert, you need to connect to the database, which you are already doing. To update database connection on the client computer you can use a tool like this one http://r-tag.com/Pages/CRDataSource.aspx.
I have a VFP 9 application that make invoices, it works fine with its default database(.DBC) I am trying to port the front end of the application (EXE) to be used with Oracle 10g Express as back-end through ODBC or any other suitable method. I do have the complete project source-code.
The application has two style forms single record editing forms, and master detail forms these forms just adds/edit/delete Search.
This application was not developed by me. I am required to keep it as it is. I do keep regular backups but its database files (.DBF) get corrupted after any OS / Power failure. So i am thinking to transport all the data to oracle database and want it to be edited / added with existing VFP EXE with data in oracle. and get rid of DBF crashes.
my problem in this scenario is:
1) I can connect to DB with ODBC. have all data from DBFs to Oracle Database but have problem with view/edit/issues it won't work as normal.
2) I am not able to use VFP Wizard to generate Data Entry form with ORACLE REMOTE VIEW. that can view / add/ edit data
3) Can not find any way to change database Source in VFP database designer to replace tables with oracle remote views VIA ODBC.
Thank you in advance. any help suggestion or guideline is welcome and much appreciated.
Regards.
Unless the application was designed to deal with a remote data source, rewriting it to talk to Oracle is probably a large job. Before you do that, have you considered simply adding uninterruptible power supplies (UPS) to each computer involved. Data corruption in VFP is generally due to interruption; providing a way for users to shut down properly when power fails may solve your problems.
I'm using Oracle SQL Developer 3.0.04. Trying to connect to a remote DB. Don't have any issues with database connection, it connects.
But when trying to view a selected tables rows a small progress bar within a small dialog box titled "Display Results" appears saying "Waiting for Checking if Object is Editable" and the progress is stuck. Cannot see any data of the selected table.
I tried to export the schema and data, but it freezed at once. So I closed SQL Developer.
Tried to attempt that again but now cannot even view the tables details.
Used TOAD in another machine and connected using that, no issue then the table listed all the data. Checked on the remote machine using putty and "sqlplus" to connect and the data showed as expected.
So that tells me that something in my local machine is wrong. Cannot connect using SQL Developer. Has anyone out there faced similar issue? please any idea on this matter?
Thanks
Did you try connecting to any other database, remote and local ? Does this happen with every database or only one connection? Perhaps something is wrong with that installation folder of SQL Developer, perhaps something got corrupt while it was stuck. Perhaps try to download the latest version of SQL Developer from this link and try again.
We are doing a feasibility on what we're going to propose as a solution to a client who wants to migrate to a .NET based solution. Part of the data resides in UniData. What is required can be achieve using the following tool:
http://www.welland.com/export.html
The above product ETLs data from UniData to SQL Server.
As a first step, we want to be sure that there are no hitches in getting the data through SSIS from UniData to SQL Server.
Since we don't have an environment to test this we have to check mostly on the net. But most of the discussions regarding UniDate and SSIS don't look like the problem got solved. The main problem seems to be that people aren't able to get hold of a proper ODBC driver. If the data is converted into XML, then it looks like it's working fine.
Has anyone done this and know that this can go through without any problems?
Cannot say I've done it, but Rocket Software has 2-user license versions of UniData available for download, so at least you would have a system to test on.
We are actually working on this process now -- Unidata to SQL through SSIS. We worked with Rocket Software to get the OLE DB working... ODBC was never fast enough and before there was not OLE DB... Now there is. You have to do some work on the UNIDATA side once the OLE DB is install but that is an answer for another day. So far we have no issues except the work to get it setup.
