Image retrieval from the database

Currently running Portal 3.0.6.5.5 on RDBMS 8.1.7, Solaris 2.8.
I have a table that has a blob column containing an image (jpeg's though I don't think this matters). I have written a PL/SQL portlet to display information, from this table. To display the images I am writing the following html tags :
<IMG SRC="PORTAL30.wwa_app_module.file_download?p_block=DEFAULT&p_object=IMAGE&p_source=AAAI9YAAEAAAFSyAAS">
Where IMAGE is the column name and the value in p_source is the rowid. Initially this worked fine, but more now more often then not the page is simply displaying the image area and not the image. The call is working to a certain extent because the image area is the correct size.
What could be causing this problem?
For information I am using IE 5.50.4522.1800, if this problem is browser related.
Thanks

Can I use stored procedures to improve data retrieval from the database?

I have been requested to get multiple pieces of data from multiple tables and return the output in an array for use in a Java program.
Eliminating multiple calls to the database. Currently, the data is retrieved from the database in multiple steps but to eliminate
possible bottlenecks in the future, I created several complex sql statements.
For instance,
In the first table there are 20 columns of data. has a column named type which can have the one of these values: line, inn, or bsc
In the second table there are 6 columns of data. has the additional data for type line
In the third table there are 7 columns of data. has the additional data for type inn
In the fourth table there are 2 columns of data. has data regardless of type
etc...
Depending on a specific column value retrieved (inn) from the first table:
I need to collect all 20 columns in the first table and get all the columns in third table and the columns in the fourth table, etc.
Question: How can I remove the duplicate primary key columns without specifying for each table the column names to be returned?
I used the wildcard SELECT * because I didn't want to have to update the retrieval methods if additional columns are added to these
secondary tables.
example of my sql for type inn data:
select * from first_table f, third_table s, fourth_table t
where (f.column1='xxxx' and f.column2='xxxx') (the 'xxxx' are passed into the sql statement)
and
((s.column1=f.column1 and s.column2=f.column2)
and
(f.column3=t.column1));
Currently, I've duplicated the separate sqls for each valid type found in the first table (at least a dozen types). The only difference is
the table name. Instead of the third table I use the second table, etc.
The MAIN Question: How can I set this up to have one sql to handle each type? I want to eliminate having over a dozen duplicated sqls. Can I
incorporate this into a stored procedure or something? If so, how? Can anyone provide sample coding?
Your help is very much appreciated. Thank you.

Hi, Salah.
Use "Exec" in your query to run procedures.
SAPbobsCOM.Recordset oRS;
oRS = (SAPbobsCOM.Recordset)pCmp.GetBusinessObject(SAPbobsCOM.BoObjectTypes.BoRecordset);
oRS.DoQuery ("EXEC YourStoredProcName");
Triggers are not supported in SDK.

How do i set the transparency of an image retrieved from a database? (image was stored as blob)

I had stored a png image into a database, when i retrieve it and display it the background is no longer transparent?
I am loading the blob returned from the select statement by using the "loadBytes" method of the "UILoader" class.
Thanx in advance

If you want to stick with adjusting the scale you can do this two ways. Edit the value graph or edit the speed graph.
The problem is that a camera move, a zoom or a dolly in, is not linear and scale is. This means the graphs are not a good representation of what you'll see visually. This makes them hard to use. At a constant rate for scale the appearance is that the increase in size slows down to closer you get to the final value. In other words, as you scale an object up at a constant rate, the visual appearance is a gradual slowing.
A speed graph edited to look like this gives the appearance of a constant rate scale of the layer when you expect an acceleration at the end. There's just not enough granularity in the graph editor or enough control to predictably achieve the results you want.
You'll have better luck editing the value graph to look something like this:
While this looks extreme, you will get closer to achieving the results you want using the value graph. Once again, the amount of control and the resolution of the graph combined with the visual tomfoolery that scaling an object brings with it makes this a difficult way to achieve predictable results.
You select the graph you'll edit by clicking on the second icon from the left.
As I said before, you'll have much better luck getting the look you want if you make the layer 3D and move a camera toward it.

Where are APEX images retrieved from in an n-tiered environmen?

I notice when using Glassfish as part of my APEX environment I am required to copy the images to an /i directory on the Glassfish server under the Glassfish domain.
The question arises --> When APEX needs to render an image, is the image retrieved from the database/database server or from the Glassfish web server?

If you're using Glassfish and the APEX Listener (or OHS) then images referenced using <tt>/i/</tt> / <tt>#IMAGE_PREFIX#</tt> are stored on and retrieved from the web server file system. If using EPG then they're stored on and retrieved from the database using the XMLDB repository.
If the image is referenced using <tt>#WORKSPACE_IMAGES#</tt>, <tt>#APP_IMAGES#</tt>, or declarative BLOBs then they're stored on and retrieved from the database.

How to retrieve the large data from the database

in my program, I want to operate the data retrieved from the database. but there are too many rows in the ResultSet . so when I try to get the ReusltSet from the database, the error of "java.lang.OutOfMemoryError
" will appear . because there are two million rows contained in the ResultSet, So I want to know whether there are some methods to deal with this problem.
anyone can give me some tips or recommend some papers and books to me.
thanks!!!!

the program is developed for the data warehourse, you know there is a large number of data in data warehourse. so I think I have to deal with the very large ResultSet in my program, this code is a example for my problem :
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class Untitled1 {
    String user = "";
    String password = "";
    public void createTable() {
        try {
            Class.forName("com.sybase.jdbc3.jdbc.SybDriver");
            System.out.println("Good to go");
            String url = "jdbc:sybase:Tds:59.64.137.240:5000/TJ";
            Connection conn = DriverManager.getConnection(url, user, password);
            System.out.println("connect successfully!");
//            Statement st1 = conn.createStatement();
            String sqlsentence2 = "SELECT DISTINCT caller FROM upcdr";
            PreparedStatement st2 = conn.prepareStatement(sqlsentence2);
            PreparedStatement st3 = conn.prepareStatement("INSERT INTO callerTable VALUES(?)");
            System.out.println("createstatement successfully!");
//            String sqlsentence1 = "CREATE TABLE callerTable (caller CHAR(18))";
//            st1.executeUpdate(sqlsentence1);
//            System.out.println(sqlsentence1);
//            st1.close();
            ResultSet rs = st2.executeQuery();
            while (rs.next()) {
                st3.setString(1, rs.getString("caller"));
                st3.executeUpdate();
                System.out.println(rs.getString("caller"));
            st2.close();
            st3.close();
        } catch (SQLException e) {
            e.printStackTrace();
            System.out.println(e.getMessage());
           System.out.println( e.getSQLState());
           System.out.println( e.getErrorCode());
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
    public static void main(String args[]) {
        Untitled1 cct = new Untitled1();
        cct.createTable();
}at here, the table "upcdr" is very large, it has two million rows. when I run this program , the error will happen. someone told me that if I use the cursor, because it will retrieve one row from the database every time, so it will not produce a very large ResultSet, then the memory would not be used out. but I am not familiar with that aspect. so I think if anyone can give me some advice.
thanks!!!!

How can I map an image (JPEG) from the SQL database image string

I saved the image into SQL database, see attachment (SaveImage2SQLDB.rar), while I have some trouble to retrieve the image. I also attached the vi which I used to convert the string to image. The string already has a value I obtained from the database. Can anyone tell me the reason why it didn't work.
Thanks in advance.

How do i store and fetch image from the Database(Access)

i am facing one problem in inserting the image into the database.the steps i followed as
1)i have created one database(access) as "Image" and into that one table as "Image" and field as "image"
type of the field is ole object.
2)i have inserted one image into the image field through "database.vi"
3)now i am trying to get the image from the database by "Fetching Example.vi"
4)it will succesfully retrieve the image from that field .
5)but when i close the both programs and reopen those that time i am unable to get retrieve the image.

I would like to suggest different approach for saving the images in the database.
I was working on Medical Imaging Company. The way we save the images in real-time was by writing the name and path of the images to database.
The images themselves where saved directly to disk.
I don�t think that access is very good in taking care of GBytes of data.
It happens some time that the database gets damage. If you have the images separately you can create fix procedure. (We had one).
Good Lack,

Crystal Reports - Failed to retrieve data from the database

Hi There,
I'm hoping that somebody can help me.
I've developed a crystal report from a stored procedure which I wrote. I can execute the stored procedure within SQL Server and within the Crystal Reports designer without any errors. Furthermore, I have imported the report into sap and can run it within SAP from the server without any errors. SAP version 8.81 PL5
The issue is that when it's run from a client machine, I get the following error: "Failed to retrieve data from the database. Details: Database Vendor Code: 156. Error in the File RCR10010 {tempfile location}
Here's a list of things which I have tried, all to no avail:
- Checked user permissions to ensure that they have proper authorizations
- Re-set the datasource connection and re-imported the report to SAP.
- Exported the report and reviewed the datasource connection and re-imported to SAP.
- Tried to run the report on multiple machines to ensure that it's not machine specific
- Tried to run the report using different users to ensure it's not user specific.
- Tested other reports built from stored procedures on client machines to ensure that they work.
Any assistance in this would be GREATLY appreciated.
Thank you

After further testing, we found that the report could be run within SAP on any work station which had the CR designer installed on it.
As it turns out, the procedure which I wrote has temp tables in it. The runtimes built into the SAP client install do not support creating temp tables when executing the report from within SAP. Which is why the report could not retreive data.
To work around this, I installed external runtimes which were the same version of the Crystal Report and now the report can be run within SAP from any workstation which has the external runtimes (and not just the runtimes within the SAP client).
I hope this makes sense.

Failed to retrieve data from the database crystal reports 2008 in SAP B1

Hello friends,
I am using Crystal report 2008 with SAP B1 PL 8.8. When I run any report, it runs correctly from Crystal Report. But whenever I try to open the same report through SAP ( Tools -> Preview External Crystal Report ), it prompts the parameters for that report and then open up the crystal report window and throws an Error message ("failed to retrieve data from the database. Details [Database Vendor Code: 156]").
Please any one suggest me the corrective solution.
Thanks in Advance,
Keyur Raval.

I had the same problem in SAP B1 2007. Report worked fine except when it was open from B1. Generally there may be different problems. In my case the same problem was caused by using some procedure which was in a specific schema. Changing the schema into "dbo" solved the problem.

Display Image from the database but prevent it from refreshing on every pages

Hi there,
I can see there are many discussions around this but my query is slightly different. I'm writing this on behalf of one of my developers. (sorry for my ignorance on techie stuff.. :-))
A logo is being displayed on a few pages, which is called from the database. However, the problem is that - this logo refreshes every time when you traverse to each page causing a performance issue or sometimes slow loading of the image.
My question is - how do we stop it from loading on each page from the database?. I would rather load once when the main page loads initially and then maintain this on other pages too.
We can keep this logo on a file system (FS) and display it via CSS/HTML/frame but since we want to keep it flexible/dynamic where a user can upload a new one whenever it changes and hence DB seems to be the suitable option (in my opinion).
Can someone please help?
If you need any further info around the coding how it is being done at present, pls let me know.
Thank you

read this http://docs.oracle.com/cd/B28359_01/appdev.111/b28393/adlob_tables.htm#g1017777
you can cache lobs in the database too
you can also upload the pic in your file system using utl_file package and then put the image in the working directory mentioned in i.war
you can then reference the image and it will not be stored in the database and will be cached

Failed to retrieve data from the database/invalid argument provided when employing link between two web services datasources

Post Author: vpost
CA Forum: Data Connectivity and SQL
I am trying to join information from two related web services within CR XI. I have successfully set up the web services as data sources have been able to get to the point where I get good data back. However, when I try to pull in certain fields, I get an error that says "Failed to retrieve data from the database/invalid argument provided". Here's the scenario:
The web services are structured as follows:Web Service 1 (Artist) has attributes of Artist Name and Date of Birth.Web Service 2 (CD) has attributes of CD Title and Release Date. Underneath each CD are songs, each of which have a Song Title and Artist Name.
I have defined both web services and defined a link between Artist.Artist Name and CD/Song.Artist Name. I am able to run a report with Song Title and Date of Birth that crosses web services. I am able to run another report with Song Title and CD Title that crosses the different levels in the second web service. However, if I add CD Title to the first report or Date of Birth to the second (both of which effectively force CR to employ the link between the two web services AND the CD/Song hierarchical structure in the second web service, I get the aforementioned error.
Any assistance understanding how multiple web services can be linked in this manner would be greatly appreciated.
Thanks in advance.

Not sure about your exact situation, but having similar problem with another application and have tracked down to security. Added user to group Domain Admin and it works fine. It appears to be accessing a subdirectory which it does not have permission to use and then times out and returns the "invalid....". Seems that once the query just over a certain size (and I'm not sure what triggers this) it needs to make use of temparory file disk, intead of ram.
I'm still trying to track down which temporary it's trying to uses - so if you have any ques.

Hi,
Are all your data in the View or each time you run a query it update the View? Please try to update your View then run the Report again, much better if you delete the original View and replace with a new one,

Failed to retrieve data from the database.DB Vendor Code 156

Hi,
We recently migrated our scheduled Crystal Reports from BO XI R2 platform to BO XI 3.1, and are having issues with select reports that pull from the same SQL database. The tables and fields exist in the database - and I ran the SQL in a different tool and the syntax is correct. When I try to run an on-demand or schedule one of these reports in 3.1 Infoview I receive the following error:
Failed to retrieve data from the database. Details: [Database Vendor Code: 156 ]
Running:
CR 2008 SP2
BO XI 3.1 SP2 (FP 2.7)
Please advise! Thanks!

Hi LuAnn,
Not really clear what he said but I believe this is correct. The BOE servers are typically running under the local System Account. So when it passed the report job from the BOE Server it is the Local System account that the database is getting. We only do single hop for security. Which means if you are logged into InfoView under your local domain account and try to run a report BOE will not, unless specified in the custom database connection options in the CMC, pass your credentials to the DB but will pass the local system account credentials which is likely why these reports are failing.
As A TEST only Ask your Administrator to set up a user account in MS SQL Server that has rights to run all reports. Or when you create the report check on the option to use Trusted Authentication. Then when the reports are published to BOE your log on credentials should get passed to the DB server through BOE.
You'll have to more testing to find a Use account that you can run BOE Servers under and still maintain DB security and report level security that works for you. I also suggest you post your security questions to the BOE Administrator forum to get help configuring all of this and what others are doing.
Thank you
Don

Failed to retrieve data from the database Error

I had some reports setup in Crystal XI based on a Sql server but recently we had an upgrade, the database has been moved to IBM Informix.
There is a certain table that seems to be causing the problem.
The error:
"Failed to retrieve data from the database
Details: 42000:[informix][informix ODBC Driver][informix]A syntax error has occured .[Database Vendor Code:-201]".
I run the same query in MS Access and it seems to run fine.
I even tried to do a simple dump of the table onto Crystal but no luck.
Any help is appreciated.
Thanks!
Achett13

Hi,
It seems your ODBC Driver is not compatible, try to download a driver which supports Informix through CR XI. I think you may have to download Data Direct Drivers 5.1 version to access Informix data tables through CR XI.
You can google it for Data Direct Drivers 5.1
