I am trying to follow a simple guide on how to export images from Microsoft SQL Server to my local disk. I can connect to the data source just fine but when I connect the "Export Column Transformation" task and open it to edit it I see no options. Is this a permission issue or something I am totally not thinking of? Any help would be great!
What I'm seeing:
What I should be seeing:
select your data from a OleDB source.
Add a script component transform (it is really a destination)
Add your varbinary column to readOnly input column
Add this code:
using(var ms = new MemoryStream((byte[]) Rows.varbinaryColumn))
{
System.Drawing.Image img = System.Drawing.Image.FromStream(ms, true)
img.Save(#"c:\mydocuments\image.jpg");
}
Note: MemoryStream is in System.IO

I'm trying to import data from a csv file on my local machine into an SSRS report. I have used this connection string
and when I try to execute the query in the query desigener window I get the required data.
but when I come to run the report I get the error that ssrs cannot connect to the datasource. When I hit test connection in the datasource properties window I get this error.
I don't understand why it would work in the query editor but not in the general report. Can anyone point me in the right direction as to what I'm doing wrong?
I'm trying FastReport.Mono on Linux (CentOS 7) to see if I can make an app to generate reports. Example Mono app seems to work fine with PDF and JPG export from custom dataset.
Now I need to query data from MS SQL database. I have a sample report that works well under Windows, but fails on Linux:
private static void ReportExportJPG()
{
Report report = new Report();
report.Load(#"sql-report.frx");
report.Prepare(); // <<<--- Error here
...
}
Error message is:
Cant find object MsSqlDataConnection
Feature table says that MS SQL connectivity (nor ODBC, nor many others) is not available in FastReport.Mono. Does this mean it's entirely missing or I should use other ways and provide ready-made connection to FastReport somehow? If so - How?
P.S. Running Windows report generator with MS SQL connection under Wine works well, so I assume connecting to MS SQL from CentOS is somehow viable.
I was able to resolve this by adding the following to my project source:
using FastReport.Data;
using FastReport.Utils;
...
RegisteredObjects.AddConnection(typeof(MsSqlDataConnection));
sup?
I got this problem wich has been slowing down my production a lot, hope u guys can give me any tip on how to solve it....
I'm currently using EF6 and a custom ConnectionString with a connectionString builder class that reads and external xml file.
My database is all set up and running in SQL 2010 and Management Studio ok, but whenever I generate the edmx file, it generates the class mappings okay, I've compared the original ConnectionString to my ConnectionString Builder they're the same, changed the :base to receive a custom ConnectionString, all set.
But when I try to save changes it doesn't find the table object, I have deleted it, created again from the start, still same "Invalid database object Dbo.TableName" error.
Does any one have a clue on this?
Thanks in Advance!
This error is not coming from Entity Framework but directly from the database.
Use SQL Profiler and include in the trace the "DatabaseName" and "ServerName" and you will find out it's not the same as your expected.
The only other options which this issue happen is if your "tableName" is not the same as the table name in SQL, so run the SQL from the SQL Profiler directly into SSMS.
Please I need help from someone possibly from balusC and or anyone out there.
I have been trying to upload picture files above 390kb into varbinary(max) datatype in microsoft sql server 2008 but I can't, instead I get the exception below.
java.sql.SQLException: [Microsoft][ODBC SQL Server Driver][SQL Server]The text, ntext, or image pointer value conflicts with the column name specified
Am using primeface fileupload component to get the image needed.
The method am using to send the file into the database looks like this:
pstmnt.setBinaryStream.(2,uploadedFile.getInputStream.(),uploadedFile.getSize());
But when I try uploading files below equal to or below 390kb, it uploads successfully.
I have been making research on how to solve this and these various research led me into updating my sql server driver to sqljdbc4, and jtds.
I also tried enabling filestream on my database and the column that accepts the picture but it still does not work. Please I need help from someone, because I have been on this for up to three weeks now. ANY kind of help will be appreciated. Thank you all.
its now working. it was actually my jdbc driver. I changed it to jtds as pedrag maric advised but it wasn't working at first because I didn't configure it well enough to work with my app. Simply put, I didn't specify in DriverManager.getConnection(jdbc:jtds:sqlserver/ blah blah blah);. Rather what I was still using even after I added the jar file to my classpath was DriverManager.getConnection("jdbc:odbc:databasename","sa","****"); mehn!! I was soooo happy when it worked.
I am new at doing SQL server data tools on VS 2010. However what I try do is:
I have created a textfile and imported it as a flatfile
I try to connect the flat file (with the green arrow) with a OLE DB but get the error:
Component OLE DB source has no inputs, or all of its inputs are
already connected to other outputs. You may be able to edit the
component to add new inputs to it.
Why do I get this error?
When I open the flat file a have diffrent rows and data in it, so there actually exists data :/
you need to connect to an OLE DB Destination not source
