This topic explains how to create and edit an SQL query in dbForge Fusion
To create a query:
The dbForge Fusion SQL editor provides many features that make it easier for you to write and manage your code. Let’s explore some Intellisense-like features that assist you while coding.
For an example, let’s use the HR database and perform a sample query where we display all the employees working in the Shipping department, department ID is set to 50.
Start typing the SELECT statement. Enter first three letters “sel”. dbForge Fusion shows you the list of the relevant keywords
and snippets. You can select the SELECT keyword from the list and press ENTER. The keyword appears in the SQL editor.
You can also select the “sel” snippet from the list and press the TAB button. In this case the SELECT * FROM statement appears in the SQL editor.
If you start type the same letters “sel” a little faster, before the list appears (by default the list has 200 ms delay), a little tool tip appears next to the letters. It signals that you can press the TAB button to complete the statement automatically by inserting a snippet.
Regardless of the method you choose, the SQL editor displays the SELECT * FROM statement.
Now, lets type a table name from which we want to retrieve the data. Start type “e”. dbForge Fusion shows you a list of valid members from the HR database. If you continue typing characters, the list is filtered to include only the members that begin with those characters. After selecting an item, you can insert it into your code by pressing TAB or ENTER. dbForge Fusion also shows a quick info for every highlighted item in the list. It allows you to see the object structure immediately.
The EMPLOYEES table comes the third on the list, so choose it and press TAB or ENTER to insert it into the SQL editor. dbForge Fusion assigns the alias for the EMPLOYEES table automatically.
We need to select employee categories that are stored in separate tables. In a similar way, either type or insert the JOIN keyword and press ENTER dbForge Fusion shows you all available solutions to implement JOIN. Select required statement and press ENTER.
Place the cursor after the asterisk character and press TAB.
dbForge Fusion shows the columns list that are available in the EMPLOYEES table.
There is no need to retrieve all the columns from the EMPLOYEES table, so we can leave only required ones.
The last step is to press F5 to execute the query.
We got what we wanted.
As you can see, Intellisense-like feature provided by dbForge Fusion allows you to create complex queries in a few keystrokes.
