Copy & Paste Imports from Excel to Oracle using SQL Developer

Oh, I so DO love hearing about things that ‘we cannot do.’ This morning I read that in an article that Oracle doesn’t allow you to copy data from Excel and paste directly to a table.


Add as many rows as you want and paste from your spreadsheet.

In the video you see me selecting the cells in the Oracle table editor before pasting the new ones in, but you don’t actually need (more...)

Returning BLOB file size

Occasionally I'll want some form of report noting file sizes of blobs in a database.

The solution is relatively simple, and I thought I'd write it up here for a place to copy syntax each time.

APEX users also have a handy table to verify this against (apex_application_files). Well, a synonym/view that ultimately maps to the core table wwv_flow_file_objects$.

It contains a doc_size column, which is no doubt evaluated at some point during upload of (more...)

SQLDev: How unshared worksheets should work!

Unshared worksheets are created to have a private connection to the database.  When that unshared worksheet is closed, the connection and session for it should disappear as well.

This graphic shows what should happen!

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

In this post I’m going to show to synchronize the remote and local repositories after an existing file in local gets modified. What I’ll do is modify the sp_test_git.pls file in our local repository and then push those changes to the remote repository (GitHub).

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...)

SQL Developer’s Interface for GIT: Interacting with a GitHub Repository Part 1

In my previous post, I showed how to clone a GitHub repository using SQL Developer. In this post I’m going to show to synchronize the remote and local repositories after remote gets modified.

Here I use GitHub to commit a file called sp_test_git.pls.  You can create files by clicking on the icon the red arrow is pointing to.


The content of the file is a PL/SQL procedure that prints a message.

SQL Developer’s Interface for GIT: Cloning a GitHub Repository

SQL Developer 4 provides an interface that allows us to interact with Git repositories. In this post, I’m going to show how to clone a GitHub (A web based hosting service for software development projects that uses the Git revision control system) repository.

First you need to sign up for a GitHub account. You can skip this step if you already have one.

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

Issues with using latest release of ODM

The title of this blog post makes it sound more dramatic than it actually is.

The reason for this blog post is down to me receiving a recent comment on the blog, plus having received numerous emails and a recent OTN Discussion Forum topic for Oracle Data Mining.

The main thing that they have in common is that if I use the latest version of Oracle Data Mining (ODM) it tells me that I need (more...)

Installing Java, Oracle 11g R2 Express Edition and SQL Developer on Ubuntu 64-bit

A while ago I tried to install Oracle 11g R2 Express Edition on a 64-bit Ubuntu machine. This proved to be not as easy as you would expect. There are many blogs and articles about this subject and I tried a number of them. Unfortunately neither of the instructions seemed to work completely on my machine. With the combined information from the authors, I finally got it to work and I’ll gladly share my recipe (more...)

ODM Graph Node new feature

With the recent release of SQL Developer 4.0.1 there has been some very minor bug fixes for Oracle Data Miner. But there has been one particular enhancement that I wanted to have a look at. This blog post will look at this new feature and how you can use it too. In the previously released version of the Oracle Data Miner tool we had a Graph Node. This is really a new feature (more...)

The OLAP Extension is now available in SQL Developer 4.0

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...)

Clickable SQL*Plus Errors

Running lots of scripts in SQL*Plus is nice when they are working correctly. But what about when they fail?  Its a pain to figure out what went wrong, unless you have a log file and even then, you have to hunt the errors down.

Well, I've had enough of that. (more...)
