Currently, I am zooming in and switching between diagrams to top left... [Read More]

Rename multiple exported Files after using SQL Developer’s Cart to export from Oracle database

Greyed out connections in SQL Developer

After upgrading to SQL Developer 4.1.2.20 a number of users noticed that some connections in the left hand pane were greyed out. I had the same experience for myself.

SQL Developer’s Interface for GIT: Interacting with a GitHub Repository Part 2

First, I proceed to open the sp_test_git.pls file using SQL Developer, add another dbms_output line to it and save it. The moment I save the file, the Pending Changes (more...)

Your account will give you access to public repositories that could be cloned (more...)

SQL Developer’s PL/SQL Debugger and Oracle 12c

The PL/SQL Debugger works pretty much out of the box when used with a previous Oracle version. These are the things we needed in place before we could start debugging PL/SQL:

  1. A grant of the DEBUG CONNECT SESSION privilege.
  2. EXECUTE privilege on DBMS_DEBUG_JDWP.
  3. EXECUTE privilege on the stored procedure you want to debug.
  4. Make sure the stored procedure is “Compiled for Debug”.

Jeff Smith talks about it in this post.

But what happens when you (more...)
