Because Apex has direct access to Salesforce records that are stored in the database, you can embed SOQL queries in your Apex code and get results in a straightforward fashion. When SOQL is embedded in Apex, it is referred to as inline SOQL.
To include SOQL queries within your Apex code, wrap the SOQL statement within square brackets and assign the return value to an array of sObjects. For example, the following retrieves all account records with two fields, Name and Phone, and returns an array of Account sObjects.
Account accts = [SELECT Name,Phone FROM Account];
Some queries in this unit expect the org to have accounts and contacts. Before you run the queries, create some sample data.
// Add account and related contact
Account acct = new Account(
// Once the account is inserted, the sObject will be
// populated with an ID.
// Get this ID.
ID acctID = acct.ID;
// Add a contact to this account.
Contact con = new Contact(
// Add account with no contact
Account acct2 = new Account(
Name=’The SFDC Query Man’,
Description=’Expert in wing technologies.’);
The Developer Console provides the Query Editor console, which enables you to run your SOQL queries and view results. The Query Editor provides a quick way to inspect the database. It is a good way to test your SOQL queries before adding them to your Apex code. When you use the Query Editor, you need to supply only the SOQL statement without the Apex code that surrounds it.
Let’s try running the following SOQL example:
SELECT Name,Phone FROM Account
All account records in your org appear in the Query Results section as rows with fields.This training is very useful to learn about the basics of SOQL in salesforce.
