Apex SOQL 查詢中的變數引用

要在查詢中引用變數，請在變數名稱前新增冒號（:)。

Datetime targetDate = Datetime.now().addDays(-7);
List<Lead> recentLeads = [SELECT Id FROM Lead WHERE CreatedDate > :targetDate];

string targetName = 'Unknown';
List<Contact> incompleteContacts = [SELECT Id FROM Contact WHERE FirstName = :targetName];
