Salesforce Query Languages - SOQL & SOSL
In Salesforce, both SOQL (Salesforce Object Query Language) and SOSL (Salesforce Object Search Language) are query languages used to retrieve data from the Salesforce platform, but they serve different purposes and have distinct syntaxes.
SOQL (Salesforce Object Query Language):
SOQL is a query language used to retrieve records from a single object or related objects in Salesforce. It's similar to SQL (Structured Query Language) and is tailored specifically for querying Salesforce data.
Key features of SOQL include:
- SELECT Statement: Used to retrieve specific fields from records.
- Filters and Conditions: WHERE clause allows filtering records based on specified conditions.
- Relationship Queries: Allows querying related objects using relationship fields.
- Aggregate Functions: Supports aggregate functions like SUM(), AVG(), MAX(), MIN(), and COUNT().
- Ordering and Sorting: ORDER BY clause enables sorting results based on specified fields.
Example of a SOQL query:
SELECT Id, Name, Account.Name FROM Contact WHERE Account.Type = 'Customer' ORDER BY Name LIMIT 10
- FIND Clause: Used to specify the search term or terms.
- RETURNING Clause: Specifies which objects and fields to return in the search results.
- IN Clause: Allows specifying specific objects to search within.
- Limitations: SOSL doesn't support all types of conditions and filters like SOQL. It's primarily focused on text-based searches.
