I’m always a bit surprised when I find a SQL Developer user who does NOT know about the Instance Viewer! Of course you loyal readers know all about it. But you’re busy – you don’t have time to tell your friends. So just send them this video, and I’ll tell them about it. In a nutshell: it’s a performance dashboard in SQL Developer. It will show you what’s happening in your database, all in one…
I don’t normally blog on a Sunday, but I’m confined to my bed/couch for the next few days, so I might as well answer another question! This from the YouTube: “Hi Jeff, Can you please share similar example where REST service is calling a package.procedure with IN and OUT parameters and we can pass IN parameters to get the result?” So, absolutely you can do this, and of course I’ll show you how. My solutions…
I’ll show you 3 cool tips and tricks for working with PL/SQL in SQL Developer…in under 7 minutes! In-code navigation – click into where your objects are declared Test Query – see if your SQL is gonna work BEFORE you compile it Using the Code Outline For those that can’t do video, basically you can Ctrl-Mouse-Hover Navigate ANYWHERE Not just on tables, but also on local variables. Right-Click to Test a Query Open and Use…
We recently (18.2) added a new way to generate execution plans in SQL Developer – we generate a call to DBMS_XPLAN for the SQL ID at your cursor position. DBMS_XPLAN is a package, and one of it’s procedures is ‘DISPLAY_CURSOR’: This table function displays the explain plan of any cursor loaded in the cursor cache. In addition to the explain plan, various plan statistics (such as. I/O, memory and timing) can be reported (based on…
15 minutes overview of how to use these features in Oracle SQL Developer: Get an Explain Plan Customize the display of the plan Get a cached plan Use DBMS_XPLAN Compare Plans Use Real Time SQL Monitoring Use AutoTrace. And if you want an awesome video, MUCH more in depth about how to read a plan, then I suggest this from @sqlmaria.
I have some code… 7436262525d06565629ed5_000003 I can guess that GIVE_RAISES is a procedure of some kind. But now I want to open it, or ‘go to it’ or ‘step into it.’ And I want to do so without having to pick up my mouse. So I could tell you about the Ctrl+Click trick, but that’s all mouse. So what’s a child of the 80’s to do? Define a keyboard shortcut for ‘Open Declaration’ and then…
Ok that title has a TON of buzz and marketing words in it. But, we have the Oracle Cloud. And available there is a service where we take care of your database for you – Autonomous. We make sure it’s up, and that it’s fast. We have 1 autonomous cloud service today and will have and second one coming SOON. These services come with an S3 compatible Object Store OSS (Oracle Object Storage, complete with…
SQL tuning can be fun. The database gives us MANY things to help with this. There is even a nice set of views that contain everything we need to know about our SQL and their exectution plans. And, we have a really cool PL/SQL package, DBMS_XPLAN for generating reports on our troublesome queries. The not-fun part, is going from a SQL statement to the SQL_ID. Now, SQL Developer has for a few releases made it…
So two areas of major performance improvements in Oracle SQL Developer version 18.2: Importing from Excel Using the Query Builder Importing from CSV was generally always pretty fast. Working with Excel consumes a lot of memory, and it took a lot of time to load an Excel file to be imported. Well, it still uses a lot of memory – an Excel file is basically a zipped set of XML files, and this will always…
I say ‘our’ because I’m doing this with Scott Spendolini, an Oracle ACE Director in the APEX community. We wanted a podcast of interest to Oracle Database developers. We like each other. We have great stories. Bad/good things happen when we get together. So, we came up with this… We want to post on a regular basis, as fast as we can record and Scott can produce them. We’ll be talking about news events in…
It’s that time of year again, we have just released updates to all of our tools! Downloads Here: Oracle SQL Developer Oracle SQLcl SQL Developer Data Modeler REST Data Services (ORDS) Let’s Talk about SQL Developer It’s a minor release, no new major features have been introduced. But, we fixed a TON of bugs. And more than several of those were reported on the FORUMS. Thanks again to everyone in the community who pitches in…
It’s a bit long at 17 minutes, but I go through the process of: creating a new table based on an Excel/CSV defining the columns checking the column names checking the column definintions is the column wide enough? defining DATEs running the export fixing errors saving the scenario so you can run it on demand Remember, if you prefer to read vs watch/listen – I have these two posts: Import from Excel to a New…
You might have heard we now have a new SQL Developer in the family: SQL Developer Web. If that’s news to you, here’s a quick video recap: Hopefully you noticed that one of the main features of SQL Developer Web (and SQL Developer Desktop!) is data modeling. We were thinking: wouldn’t it be nice if could pull up a diagram you built in SQL Developer Web into the Desktop copy of SQL Developer or SQL…
This past week we were at KScope – the premier all things Oracle conference here in the United States. The Database team were very well represented, and we did 15 minute lighting talks. Maria has already shared her slides/talks here – they were AWESOME! Here are mine. Let’s Go Shopping It’s all about the Cart. Oracle SQL Developer: The Cart from Jeff Smith Social Media – Why a Database Person Should Care Plus 3 quick…
We have a LOT of application preferences. And users have a funny habit of asking us to add MORE to every release. So, it’s great that we make it very easy to customize their SQL Developer experience via a few clicks and toggles. But, it’s kind of hard to find the RIGHT switch when you want to go change something. Well, a few releases ago – Bad Jeff for not talking about this sooner!! -…
