This topic explains how to create and edit an SQL query in Query Builder for MySQL.
To create a query:
Create a server connection.
On the Standard toolbar, click New SQL. An empty SQL document opens.
Start type a query to a database.
Click Execute or press CTRL+F5 to see the query results.
The Query Builder for MySQL SQL editor provides many features that make it easier for you to write and manage your code. Let’s explore some Intellisense features that assist you while coding.
We are going to create a sample query. In this example we will use the sakila database. Let’s display all the films stored in the sakila database, that were released after 2004.
Open SQL Editor.
Start typing the SELECT statement. Enter first three letters sel. Query Builder for MySQL shows you the list of the relevant keywords. You can select the SELECT keyword from the list and press ENTER. The keyword appears in the SQL editor.
Now, lets type a table name from which we want to retrieve the data. Start type f. Query Builder for MySQL shows you a list of valid members from the sakila 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) or by typing a space. Query Builder for MySQL also shows a quick info for every highlighted item in the list. It allows you to see the object structure immediately.
The film table comes first on the list, so just press TAB or ENTER to insert it into the SQL editor.
We need to select films categories that is stored in a separate tables. In a similar way, type the JOIN keyword and press the space. Query Builder for MySQL shows you all available solutions to implement JOIN. Select required statement and press ENTER.
Continue typing the query. You can use the Quick Info feature while typing SQL code. The Quick Info feature is a tooltip with brief information about database objects, parameters, and variables. The tooltip appears when you place the mouse pointer on the required item in the SQL script.
In case of database objects, the tooltip shows their location and types. You will find this option useful, while working with large scripts.
Use the CTRL+K, CTRL+D combination to format the query text. Now we can execute the query to see results. To do so, click the Execute button, or press F5.
The last step is to add the WHERE condition. Add the WHERE f.release_year > 2004 statement at the end of the query and press F5 to execute it.
We got what we wanted.
As you can see that code completion feature provided by Query Builder for MySQL allows you to create complex queries in a few keystrokes.
