Hello to all!
Talend Open studio Data integration 6.2.1
I have a MSSQL table called itemImages which has the below columns:
ImageID, productID, Image
The image column is blob where a jpg image is stored.
What I want is to convert the blob to jpg image and then upload it to an ftp as jpg.
What i have already did:
1. tMSSqlInput which inserts the sql rows of the itemImages table
2. tSetGlobalVar which sets a name foreach row with the key "filename" and value (String)row1.imageID
so it gives every row a variable of the imageID which I want it later for filename.
Group2 (on subjobOK):
1. Again the same tMSSqlInput
2. tLOBDownload which converts the blob to file jpg
3. tFTPPut which uploads the converted jpg files to the FTP
The job is working, it gives each blob a filename (the id) and then it uploads to FTP.
The problem is that even if the tFTPPut says that 3 rows are proccessed, it only uploads one file out of three.
If I set the component tLOBDownload to also save to the local drive of my computer it saves all three jpg files with different filenames based of the id of each one, correctly.
But at the FTPPut uploads only one of them.
Do I need any kind of loop for the job to upload all the rows at the FTP?
Thank you in advance for the help!!!
I got the Exception as Given object is not a Blob. It is of type:[B
Please tell me the Step by Step to Create the Job for download images from Database.
The component tFTPPut is a typically used as a single-component sub-job but can also be used as output component. You can connect Iterate flow from tFilelist to tFTPPut in order to transfer files to an FTP server from local.
