Essential Practices for Oracle SQL Development in 2021

Are you considering becoming an Oracle SQL developer? This is a great field with many promising opportunities. You can see how much job security you will have by looking at the market share that Oracle holds in this market.

Oracle remains the world’s most popular database management system. It has nearly 30% more active users than Microsoft SQL server.

There is a huge demand for IT professionals working in the Oracle SQL specialty. However, you are still going to have a bit of a learning curve when you are getting started.

You are likely to encounter a number of headaches when you are first getting started. Fortunately, there are a number of steps that you can take to mitigate these frustrations. The following tips will help you become a thriving Oracle SQL developer. You can also reduce your learning curve by taking Oracle online training courses.

Start by making sure that your preferences are properly configured

You need to make sure that your preferences are properly configured before you can begin implementing and streamlining any SQL database. This is true whether you are developing a database with Oracle, Microsoft SQL or any other database management system.

There are a lot of preferences that you can configure to streamline the development of your database. Here are some things to pay close attention to:

  • Setting a reasonable font in your Code Editor. This may not seem like a big deal, since it does not have any technical impact on your database. However, it is going to be important for your benefit as the user. You are going to have to spend a considerable amount of time typing, so it is important to make sure that you have a font that is not going to hurt your eyes.
  • Consider disabling the diagnostic and tuning packs in SQL developer. You want to make sure that you don’t accidentally use features that are not supported by your respective license. If you have the most premium licensed version, then this is not a concern.
  • Make sure that the debugging option is set to “step over.” Otherwise, debugging sessions are not going to work without making this change down the road.

The successful implementation of new SQL database is going to be much easier with these options set properly.

Understand how to navigate your recent statements with keyboard controls

When you are creating large blocks of SQL code, it can be very tiresome to scroll through hundreds or thousands of lines of code one line at a time. Even your most recent code can be difficult to scroll through.

The good news is that there are a lot of keyboard shortcuts that you can use. You can simply hit CTRL + UP to cycle up the screen and CTRL + DOWN to scroll in the other direction.

ANSI joins are better than using Oracle joins for joining tables

You are going to have many situations where it is necessary to join tables. The Join command is the ANSI standard. There is another option that is not used as frequently. It involves using the WHERE clause.

The second option is specific to Oracle, although you can use both the ANSI and Oracle joining features. It is a lot less work to use the ANSI style. Some of the reasons are:

  • SQL developers admit that they are likely to forget to use the WHERE clause when joining tables. This creates a number of inaccurate results.
  • The WHERE clause was meant for other purposes, such as filtering records. It was not meant to join tables. Even though it can be used for both purposes, it is easy to forget the purpose of it when you are making modifications to your code. You might think that you were trying to filter results and replace it with a different clause entirely, which would delete any table joining.
  • Most developers have an easier time reading ANSI joins. This is because it is easier to see which sections are meant for filtering and which ones are used for joins.

Joining tables is a huge part of developing successful SQL databases. You need to make sure that you use the most intuitive approach, so that you avoid future syntax errors and don’t forget to include the appropriate commands. You are much more likely to use the style appropriately if you use the ANSI standard.

Take advantage of dragging and dropping features

There are a lot of ways that you can create worksheets with Oracle. Do you have the option of dragging and dropping multiple tables into a single worksheet. This is a great feature to take advantage of if you are trying to save time.
