I just came from a DBA-dominated conference – Hotsos Symposium in Dallas, if you must know – and I came away with the impression that many a DBA out there is missing out on some key features and productivity-hacks in our dear ole IDE. I could give you 10 things, but I know DBAs are busy, so here are just 3: 1.)The Instance Viewer New since 2014 and version 4.1. Nothing to install in your…
Received this query from a customer this morning… For your information, I’m average in SQL. What I would really like to know is if you can give me some tips regarding the use of Oracle SQL Developer in relation to a completely new database. So, are there functions/tools in Oracle SQL Developer which can help me better understand a new database and it’s structure/tables/etc. I’m not looking for tips regarding creating a new database. I’m…
Does SQL developer support, col command that is used to format query results in sqlplus. like – col id heading app_id format a10 My answer was: ‘Yes.’ But I figured I should put up or shut-up a little bit, so here goes. You can read more about column formatting in SQL*Plus here (Docs). I used those same queries as a test in SQL Developer. Remember that when you use this button: … we emulate SQL*Plus…
There’s an update available for SQLcl on OTN, go get it now. We’re closing bugs left & right, and we’re super close to 100% SQL*Plus support now. As an example, we now support SET PAGESIZE 0…which comes in handy apparently if you want to spool a file w/o a leading blank line as described here.
Oracle SQL Developer has 2 client-side logging mechanisms for capturing SQL that is executed: SQL History Statements SQL History This is the SQL that you have executed in a SQL Worksheet. It’s also any scripts you have executed in a SQL Worksheet. Ran something the other day and forgot to save it to your script? No worries, pull it up in the SQL History. It’s limited by the size defined in the preferences. 100 is…
I tried to reference this post, and couldn’t find it. So apparently I have to write it now. I want to write a query. I want a bunch of column names. I could do this: But I’m very particular. Or maybe my customer is very particular. She wants SALARY then LAST NAME then FIRST NAME then EMPLOYEE ID. And so because I’m a lazy typer, I’m going to give my fingers a break and pick…
Idiom:in a nutshellIn a few words; concisely: Just give me the facts in a nutshell. Ok, so I used more than a few words, but if I told you that SQL Developer was a GUI version of SQL*Plus – I’d be leaving out a WHOLE LOT of important stuff. If that’s all you’re using it for, you might be missing out. So here are some quick-links to learn more about each of these feature areas:…
A co-worker asked me for some advice on building a report to view some CLOBs. CLOBs are fun. They let you store an unlimited (basically) amount of text. They’re not as flexible as VARCHAR2s, but they do come in handy. Viewing them in a report can get interesting though. The question came down to seeing a report like this – I suggested to my co-worker to use the SCRIPT type report instead. But then they…
Virtual columns made their debut in Oracle Database 11g. They are a value that’s not stored with the row, rather they are computed as queried. [DOCS] So I could have a column of type DATE. And I could have a virtual column of type VARCHAR2 that is computed by running a function against the previously mentioned DATE column. How would I model this? In your relational, or even logical design, you can set a column’s…
