I’m going to go out on a limb and guess that most people who use SQL Developer do not realize it has a fully-baked data modeling tool built into it. It’s not like we hide it, but we kind of hide it. To open the Data Modeler inside of SQL Developer, navigate to the View menu, and activate the Data Modeler Browser, like so – Once opened, you’ll see a new ‘Browser’ panel beneath your…
New for version 3.1, currently available as a EA download, when defining the queries used to populate views, the modeler can generate JOINs using either Oracle’s or the standard ANSI compliant syntax. Let’s step back a second. When working with a VIEW defined in a relational model, the modeler has twp choices for defining the driving SQL statement that is used to populate the contents of the view. They can code it by hand -…
Binary Large Objects – otherwise known as BLOBs. You’ve also got large objects which are composed of text – that would be a CLOB. If you hear people talk about LOB storage, they are referring to how the data in these fields are stored – outside the space reserved for the regular segments (table data.) BLOBs are frequently used to store data such as pictures in the database. You can pretty much store anything in…
Updated June 2015, current for version 4.1 There are too many options in our every day lives. We love asking for more options, but I often find myself being overwhelmed by the number of questions I have to answer before I can accomplish very mundane tasks. Do you want your latte ‘skinny’ or your cappuccino ‘wet?’ Waffle House customers are probably familiar with ‘capped, covered, smothered, & covered’ routine. Do you want a receipt with…
Update for version 4.2 and higher. As often happens, my ideas for blog posts are provided by end users asking for help. Sometimes I know the answer, sometimes I don’t. This is one of the latter cases. Chet AKA @oraclenerd asked me: ‘Tell me how to find the preference in sqldev to make a tab 2 spaces?’ I knew it had to be in there somewhere. This is a pretty basic setting for any word…
Image Left, Text Right It starts out OK, even fine really.

If you’re here to read another pro or con Klout rant, then please go somewhere else. I consider Mark Schaefer’s blog series to be the definitive take on the whole Klout business. I like Klout, and I use Klout. If you fall into this camp, please continue. Did you know that Klout has lists? You may have ignored them. And I wouldn’t blame you one bit. See, we’ve been trained to think that lists are…
View – Recent Objects will show you a list of objects you have click into via the explorer. If you need to keep a diary of objects you’ve messed with for the day, then this might do the trick. No, it doesn’t track what you did to the objects, but it does leave some bread crumbs for you to snack on later. You can invoke the object action lists directly from the panel, or if…
Spatial data in its raw format is ugly. The shapes and places it represents can be very enlightening. Here’s some raw spatial data followed by their visualization. If you worked with spatial data, what would you prefer? You can probably figure out what you’re looking at, but wouldn’t it be nice if you could get a visual confirmation? 1617195955691496c23e2ec_000003 To see the shapes, just right-click Map View, What’s that? Do you remember the kid’s game,…
Updated Feb 5, 2021 There are two ways you can view your REFCURSOR output from calling PL/SQL stored procedures and functions in Oracle SQL Developer. Using the PRINT command in a SQL Worksheet Using the classic SQL*PLUS PRINT command to view the refcursor output will work in SQL Developer just like it would work in your command line tools. You execute your program, you create a local variable or 3 to ‘catch’ said output, and…
