What are the two query languages used in Salesforce?

The two query languages used in Salesforce are SOQL (Salesforce Object Query Language) and SOSL (Salesforce Object Search Language).

SOQL is specifically designed for querying records from a single object or related objects, allowing users to use a SELECT statement to retrieve specific fields and filter the results based on conditions. It resembles SQL in its structure but is tailored for the Salesforce data model.

SOSL, on the other hand, is used for searching text, email, and phone fields across multiple objects simultaneously. This is particularly useful when you want to find records that match a certain keyword across various objects rather than focusing on a single object.

Together, SOQL and SOSL provide a robust way to retrieve and interact with data within the Salesforce ecosystem, each serving different purposes based on the type of query required. The other options mentioned do not accurately represent Salesforce's querying capabilities, as XML is a data format rather than a query language, and SQL is not used within Salesforce environments. Apex, while it is the programming language for Salesforce, does not replace the need for SOQL or SOSL for querying data.
