Question 5

A developer writes an Apex method that executes a SOQL query using user-supplied search parameters. How can the developer protect against SOQL injection vulnerabilities?

Use bind variables in the SOQL query instead of string concatenation.. Using bind variables in SOQL queries automatically sanitizes the input and prevents SOQL injection, unlike string concatenation.

Answer

Execute the query using Database.queryWithBinds() with a restricted access modifier.

Use String.escapeSingleQuotes() on all user inputs before concatenating into the query string.

Answer

Enclose all dynamic parameters in single quotes within the dynamic SOQL query string.

Question 10

An application has a requirement to query records owned by subordinate users in the role hierarchy using Apex. Which SOQL feature supports this capability?

Accepted Answer

Executing queries in 'with sharing' context where sharing rules grant access via role hierarchy. The WITH DATA CATEGORY or parent user hierarchy queries can be accomplished using standard sharing, but for role hierarchy expansions in SOQL, developers use keyword qualifiers or UserRecordAccess. Wait, standard SOQL does not have a direct 'ROLE HIERARCHY' keyword, but SOSL/SOQL supports user permission checks, or specifically, sharing rules are evaluated automatically in 'with sharing' classes. However, querying subordinate data is managed by sharing rules and record ownership.

Answer

SELECT Hierarchy FROM User

Answer

USING SCOPE subordinate

Answer

WITH ROLE HIERARCHY
