Image Overlapping Issue

AV2022 — Fri, 15 Nov 2024 21:57:56 GMT

Hello Team,

I am facing a very strange issue while importing data from Access DB to Oracle DB. Access DB is my source DB and there are two columns in the Source data Column1=NoProcesso (Datatype: Number) Column2=Logo_Image_Data(Data type: Attachment)

I have created a job using the components mentioned in the attached screenshot to export data from Access and Import it into Oracle DB

Below is the code which i have used for tJavaFlex to extract the Logos from the Logo_Image_Data column

Object obj = rs_tDBInput_1.getObject(2);

net.ucanaccess.complex.Attachment[] objArr =((net.ucanaccess.complex.Attachment[])obj);

System.out.println(objArr);

System.out.println(objArr.length);

System.out.println("Error exception");

if (obj != null && objArr.length>0) {

net.ucanaccess.complex.Attachment att = (((net.ucanaccess.complex.Attachment[])obj)[0]);

System.err.println("Attachment Name: " + att.getName());

row2.bytea = att.getData();

}

Data import is getting completed successfully without any Data loss, but the issue i am facing currently is Logos are getting Over written from column 2. For example in the source DB, NoProcesso has a value 1 and has Logo Attachment in Logo_Image_Data, and NoProcesso = 2 has no logo attachement, but after the Talend Job get executed successfully and Data import is completely in Oracle DB, NoProcesso=2 is also getting updated with the Logo of NoProcess=1. In short both the NoProcess 1 and 2 is getting updated with same Logo.

I hereby attach the screenshots of all the components and Tmapping i have created for my talend Job.

It will be of great help if someone can help me to Solve this issue.

Thanks

Anand V

Set the output column is null if no attachment in column 2, change the code a little as below:

Object obj = rs_tDBInput_1.getObject(2);

net.ucanaccess.complex.Attachment[] objArr =((net.ucanaccess.complex.Attachment[])obj);

System.out.println(objArr);

System.out.println(objArr.length);

System.out.println("Error exception");

if (obj != null && objArr.length>0) {

net.ucanaccess.complex.Attachment att = (((net.ucanaccess.complex.Attachment[])obj)[0]);

System.err.println("Attachment Name: " + att.getName());

row2.bytea = att.getData();

} else{

row2.bytea=null;

}
