Getting an image from database

Hello... I have a table in my database of employees of the company. This table has their name, address and photo plus other information. I am having trouble trying to display the photo image from the database. The photo in the database is saved as BLOB. How could you display this image in a jsp?
Thank you.

Getting Image from database in crystal report

Hi Experts,
I have a user UDF which has Image datatype. I store all the image in C:\Program Files\SAP\SAP Business One\Bitmaps\ folder.Now i have to show this image in my crystal report. When i tried to pick this image from database it gives me only the name of image with extension like abc.jpg . How could i achive this in crystal report.
Thanks and Regards

Hi Om
As you have the location of the image, you can insert it as an OLE object onto the report.
Click on Insert -> OLE Object -> specify the path of the image.
For more information, please refer to Crystal Reports help.

Error While loading a image from database

Purpose
Error While loading the Image from the database
ORA-06502: PL/SQL : numeric or value error:Character string buffer too small
ORA-06512: at "Sys.HTP" ,line 1480
Requirement:
I am developing the web pages using PSP(Pl/sql Serverpages) . I have a requirement to show a image in the webpage. I got the following procedures from the oracle website.
I have created the following table to store the images
create table DEMO
ID INTEGER not null,
THEBLOB BLOB
And I also uploaded the Images. Now I am try to get a image from the table using the following procedure .But I am getting the error message line 25( htp.prn( utl_raw.cast_to_varchar2( l_raw ) );) .at it throws the following error messages
ORA-06502: PL/SQL : numeric or value error:Character string buffer too small
ORA-06512: at "Sys.HTP" ,line 1480
Procedure that I used to get the image
create or replace package body image_get
as
procedure gif( p_id in demo.id%type )
is
l_lob blob;
l_amt number default 30;
l_off number default 1;
l_raw raw(4096);
begin
select theBlob into l_lob
from demo
where id = p_id;
-- make sure to change this for your type!
owa_util.mime_header( 'image/gif' );
begin
loop
dbms_lob.read( l_lob, l_amt, l_off, l_raw );
-- it is vital to use htp.PRN to avoid
-- spurious line feeds getting added to your
-- document
htp.prn( utl_raw.cast_to_varchar2( l_raw ) );
l_off := l_off+l_amt;
l_amt := 4096;
end loop;
exception
when no_data_found then
NULL;
end;
end;
end;
What I have to do to correct this problem. This demo procedure and table that I am downloaded from oracle. Some where I made a mistake. any help??
Thanks,
Nats

Hi Satish,
I have set the raw value as 3600 but still its gives the same error only. When I debug the procedure its throwing the error stack in
SYS.htp.prn procedure of the following line of code
if (rows_in < pack_after) then
while ((len - loc) >= HTBUF_LEN)
loop
rows_in := rows_in + 1;
htbuf(rows_in) := substr(cbuf, loc + 1, HTBUF_LEN);
loc := loc + HTBUF_LEN;
end loop;
if (loc < len)
then
rows_in := rows_in + 1;
htbuf(rows_in) := substr(cbuf, loc + 1);
end if;
return;
end if;
Its a system procedure. I don't no how to proceed .. I am really stucked on this....is their any other method to take picture from the database and displayed in the web page.....???? any idea..../suggesstion??
Thanks for your help!!!.

Display image from database with jspSmart

Hi
I have successfully uploaded and saved images into oracle(8.1.5) table DATA_TYPE(dtid number, iconname varchar2(30), icon blob). When I try to display a specific icon in my browser, I get "javax.servlet.ServletException: General error" at:
PreparedStatement pstmt = myConnection.prepareStatement(mySQL);
My code looks like this:
imgModifyDataType.jsp
<%
ResultSet myResultSet = null;
Statement myStatement = null;
Connection myConnection = null;
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
myConnection = DriverManager.getConnection("Jdbc:Odbc:Te","te","te");
String iconName;
String pDTID = request.getParameter("dtid");
String mySQL = "Select iconname, icon from data_types where dtid=?";
PreparedStatement pstmt = myConnection.prepareStatement(mySQL);
pstmt.setString(1,pDTID);
myResultSet = pstmt.executeQuery();
iconName = myResultSet.getString("iconname");
myUpload.initialize(pageContext);
myUpload.downloadField(myResultSet,"icon","application/x-msdownload", iconName);
%>
I call this JSP from another JSP like this:
<img src="imgModifyDataType.jsp?dtid=<%=pDTID%>">
If we cannt display image with the help of another jsp like this then please guide me how to modify the imgModifyDataType.jsp to a servlet because I have never worked in servlets.
Please help
Sajid

catch(SQLException a)
finally {
stmt.close();please anyone can help meee
thanks

You basically save a File to the database, so you can just re-write the data from the file back temporarily and load it into the application using the ImageIO class
// create necessary connection and statement objects
// retrieve image column
ResultSet rs = stmt.executeQuery("SELECT Image FROM dataTable");
rs.next();
Blob imageData = rs.getBlob("Image");
if( imageData != null ) {
    try {
        File tmpFile = new File("tmpImage");
        FileOutputStream fos = new FileOutputStream(tmpFile);
            fos.write( imageData.getBytes(1L, (int)imageData.length()) );
            fos.close();
        tmpFile.deleteOnExit();
        ImageIcon icon = new ImageIcon( ImageIO.read(tmpFile) );
        JOptionPane.showMessageDialog(null, icon);
    } catch(IOException ioe) {
        ioe.printStackTrace();
        JOptionPane.showMessageDialog(null, "Failed To Load Image Data", "Load Error",
                JOptionPane.ERROR_MESSAGE);

Retrieving image from database in form 6i

hello all
i'm working on form 6i...
i have uploded images into the database of customers in my application using READ_IMAGE_FILE.. IT IS FINE...
But when i am trying retrieves records into the form.... i'm getting all the data except image... Image field is showing empty..
How can i get image from database to form
can u plz help me.....
thanks

What data type you used for storing image in database. If it is long raw, then you can place an image item within your data block on form and associate it with the column name. This should populate the image by itself.
Below para is from Forms Help.
Image items can be populated in the following ways:
+1. a fetch from a LONG RAW database column+
An image item in a data block is populated automatically when the end user or the application executes a query in the block. When a fetched image is modified or replaced, Form Builder marks that record as Changed, and the next commit operation saves the new image to the corresponding LONG RAW column in the database.
Note: You cannot write a SELECT statement to select a LONG RAW value INTO an image item.
+2. executing the READ_IMAGE_FILE built-in to read an image from the file system+
+(To dynamically write an image from an image item out to a file, use the built-in procedure WRITE_IMAGE_FILE.)+

I am facing a Problem with reading images from database

Hi everybody..
any help will be most appreciated, I am facing problem with reading images from database. I am pasting my code...
string connect = "datasource = localhost; port = 3306; username = root; password = ;";
MySqlConnection conn = new MySqlConnection(connect); // creating connecting string
MySqlCommand sda = new MySqlCommand(@"select * from management.add_products ", conn); //creating query
MySqlDataReader reader;
try
conn.Open(); // Opening Connection
reader = sda.ExecuteReader(); // Executing my Query..
while (reader.Read())
byte[] imgg = (byte[])(reader["Picture"]);
if (imgg == null)
pc1.Image = null;
else
MemoryStream mstream = new MemoryStream(imgg);
pc1.Image = System.Drawing.Image.FromStream(mstream);
It says Parameter not Valid... i am reading all the images from database

I agree with Viorel. You are getting the error because the format of the data is incorrect probably because the data was modify. It may not be the reading of the database the is incorrect, but the application that wrote the data into the database. You need
to compare the imgg array data with the data before it was written to the database to see if the data matches. I usually start by comparing the number of bytes which is easier to check then compare the actual to isolate which function is changing the
byte count.
An image is binary data. The standard VS methods for reading and writing data (usually stream classes) default to ASCII encoding which will corrupt binary data. The solution usually is to use UTF8 encoding instead of the default ascii encoding.
Ascii encoding with stream often aligns the data and adds extra null bytes to the end of the data which can produce these type errors.

When I retrieve, I got 3 rows of binary data, but I don't know how to display it on the Servlet/JSP pages.I will pick this bit of your post, because you seemed to have several partly-overlapping questions.
You are going about this wrong. You need to decide what your HTML will look like before you start writing servlet code. In this case you want to have something like a table, with an image in each row, right? Now what does the HTML for that look like? It's a <table> element, and so on, but what about the images? Well this is HTML, so it can't contain the binary images. It has to contains links to the images, and the browser will download the image from each of those links and put all of the downloads together into the page it displays.
That means you can't do it all with one servlet. You need a main servlet that generates the HTML, with the <table> element and the links to the images. Probably you need some DB calls here to find out how many images you're going to have, but you don't need to get them in this servlet. You just need to generate a link for each of them.
Then you need a second servlet that gets an image. It's going to get a single row from the DB and return the binary image you read from that row. Make sure to use "image/jpg" or whatever's appropriate instead of "text/html" in your response's content type here.
I will leave you to carry on from here. First step is to design the HTML that your main servlet will produce; remember that the links it generates need to carry enough information for the second servlet to be able to find the right image in the DB.

How to get string value from database table using Visual Studio 2005?

Hi,
Im developing plugin in illustrator cs3 using visual studio 2005. I need to get the values eneterd in database. Im able to get the integer values. But while getting string values it is returning empty value.
Im using the below code to get the values from database table
bool Table::Get(char* FieldName,int& FieldValue)
    try
        _variant_t vtValue;
        vtValue = m_Rec->Fields->GetItem(FieldName)->GetValue();
        FieldValue=vtValue.intVal;
    CATCHERRGET
    sprintf(m_ErrStr,"Success");
    return 1;
Im using the below code to get the values.
AIErr getProjects()
    char buf[5000];
    int i;
    std::string catName;
    ::CoInitialize(NULL);
    Database db;
    Table tbl;
    errno_t err;
    err = fopen(&file,"c:\\DBResult.txt","w");
    fprintf(file, "Before Connection Established\n");
    //MessageBox(NULL,CnnStr,"Connection String",0);
    if(!db.Open(g->username,g->password,CnnStr))
        db.GetErrorErrStr(ErrStr);
        fprintf(file,"Error: %s\n",ErrStr);
    fprintf(file, "After Connection Established\n");
if(!db.Execute("select ProjectID,ProjectName from projectsample",tbl))
        db.GetErrorErrStr(ErrStr);
        fprintf(file,"Error: %s\n",ErrStr);
    int ProjectID;
    int UserID;
    int ProjectTitle;
    char ProjectName[ProjectNameSize];
    if(!tbl.ISEOF())
        tbl.MoveFirst();
    ProjectArrCnt=0;
    for(i=0;i<128;i++)
        buf[i]='\0';
        int j=0;
    while(!tbl.ISEOF())
        if(tbl.Get("ProjectID",ProjectID))
            fprintf(file,"Project ID: %d ",ProjectID);
            ProjectInfo[ProjectArrCnt].ProjectID = ProjectID;
            sprintf(buf,"%d",ProjectID);
            //MessageBox(NULL, buf,"f ID", 0);
            j++;
        else
            tbl.GetErrorErrStr(ErrStr);
            fprintf(file,"Error: %s\n",ErrStr);
            break;
        //if(tbl.Get("ProjectTitle",ProjectName))
        if(tbl.Get("ProjectName",ProjectName))
            MessageBox(NULL,"Inside","",0);
            fprintf(file,"ProjectTitle: %s\n",ProjectName);
            //catName=CategoryName;
            ProjectInfo[ProjectArrCnt].ProjectName=ProjectName;
            //sprintf(buf,"%s",ProjectName);
            MessageBox(NULL,(LPCSTR)ProjectName,"",0);
        else
            tbl.GetErrorErrStr(ErrStr);
            fprintf(file,"Error: %s\n",ErrStr);
            break;
        ProjectArrCnt++;
        //MessageBox(NULL, "While", "WIN API Test",0);
        tbl.MoveNext();
    //MessageBox(NULL, ProjectInfo[i].ProjectName.c_str(),"f Name", 0);
    ::CoUninitialize();
    //sprintf(buf,"%s",file);
    //MessageBox(NULL,buf,"File",0);
    fprintf(file, "Connection closed\n");
    fclose(file);
    for(i=0;i<ProjectArrCnt;i++)
        sprintf(buf,"%i",ProjectInfo[i].ProjectID);
        //MessageBox(NULL,buf,"Proj ID",0);
        //MessageBox(NULL,ProjectInfo[i].ProjectName.c_str(),"Project Name",0);
    return 0;
In the above code im geeting project D which is an integer value. But not able to get the project name.
Please some one guide me.

As I said in the other thread, this really isn't the place to ask questions about a database API unrelated to the Illustrator SDK. You're far more like to find people familliar with your problem on a forum that is dedicated to answering those kinds of questions instead.

Have a error in getting the values from database randomly

Hi to all
I am new member to this community and new to java programming, i am the one of them who got benefited through this site , with that hope i am asking u to clear my doubt.
Actually i want to get the data from database randomly, i dont have problem either in database connection and generating random number,its working fine. but when i have to get the data from database with generated random no using absolute function , i am getting an exception
eg : rs.absolute(2);
i could not move to the second row of my result set.
not only absolute function whatever the function i am using except next method, getting exception.
my code :
package practical;
import java.util.*;
import java.sql.*;
public class gen {
     Connection con;
     Statement s;
     ResultSet rs;
     public void get(int t)
          try
               rs.absolute(t);
               String question=rs.getString("question");
               System.out.println("Random question : "+question);
          catch(Exception e)
               System.out.println("get error");
     public void ran()
          Random r=new Random();
               for(int i=0;i<10;i++)
                    int j=r.nextInt(10);
                    System.out.println("random value : "+j);
                    if(j!=0)
                         try
                              get(j);
                         catch(Exception e)
                              System.out.println("ran error");
     public void connect()
          try
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
               con=DriverManager.getConnection("jdbc:odbc:ds","sa","server");
               s=con.createStatement();
               rs=s.executeQuery("select question from qa");
               ran();
               con.close();
          catch(Exception e)
               System.out.println("error");
     public static void main(String... strins)
          new gen().connect();
}

but i acheived through the code which is pasted below but i have to close the database connection for every iteration.
package practical;
import java.util.*;
import java.sql.*;
public class gen {
     Connection con;
     Statement s;
     ResultSet rs;
     public void get(int t)
          int c=0;
          while(c!=t)
               try
               rs.next();
               c++;
               catch(Exception e)
                    System.out.println("next error");
          if(c==t)
          {     try
                    String question=rs.getString("question");
                    System.out.println("Random question : "+question);
               catch(Exception e)
                    System.out.println("iteration error");
     public void ran()
          Random r=new Random();
               int j=r.nextInt(10);
               System.out.println("random value : "+j);
               if(j!=0)
                    try
                         get(j);
