Show Pictures in a Form on a Table with Report in APEX

Posted on 10. Dezember 2013 Comments

The table is called WPDBD_TEIL. The primary key is TID. In WPDBD_TEIL there is a column called BILD(german: picture/image) from type BLOB.

First click on your form and keep the name of the picture in mind. In this case, it’s P9_BILD.

Then go to your report, click on edit for the whole report and use the following code


select "TID", 
decode(nvl(dbms_lob.getlength("BILD"),0),0,null, '<img height="100px" width="100px" src="'||apex_util.get_blob_file_src('P9_BILD',TID)||'" />') "BILD"

If you’d open the report now, you only get the HTML Code. So you have to change the way APEX displays the entry. So go to the report, click on BILD and change Display as Text to Report Standard Column




The form I used was the following.


Also, in the last page of creating the form, you have to chose your own primary key, not the ROWID.




SQLDeveloper with Ubuntu 12.04, alien and the .rpm-file

Posted on 30. September 2013 Comments

There are a couple of tutorials[1] of how to install Oracles SQLDeveloper and they all say to install the sqldeveloper-XXX-no-jre.zip, in this case sqldeveloper- I didn’t read it because my first idea was the following and it also worked: It’s possible to download the .rpm-file and convert it with alien. You might have to install it with

sudo apt-get install alien


alien sqldeveloper-
dpkg -i sqldeveloper_3.

You can then start the sqldeveloper. It will ask you for the Java Path which is usually /usr/lib/jvm/java-6-openjdk and give you some kind of error, which didn’t seem to have any impact.
