Difference Between SOQL and SOSL in Salesforce

The salesforce provides main two tools for querying/retrieve data from data base those are: SOQL (Salesforce Object Query Language) and SOSL (Salesforce Object Search Language).

While working with salesforce user has two options to use to fetch records from data base but both serve different purposes and excel in specific scenarios.

In this blog let’s drive into the key difference between SOQL and SOSL to understand when to use what?

What is SOQL?

SOQL (Salesforce Object Query Language) is similar to SQL and used to fetch data from the salesforce objects. Much like the SELECT command in SQL, SOQL enables you to define the source object (e.g., Account), specify the fields you want to retrieve, and set conditions to filter rows within that source object.

Key Feature of SOQL:

1. Fetches a record from single object at a time.
2. Supports filtering clause i.e. WHERE.
3. Retrieves specific fields or records.

Example of SOQL:

Syntax:  SELECT fieldList [subquery][…] FROM objectType[,…]   [WHERE conditionExpression].

SELECT Name, Email FROM Contact WHERE Account.Name = ‘Acme Corp’

This query fetches the Name and Email of all contacts related to the account named “Acme Corp.”

What is SOSL?

SOSL (Salesforce Object Search Language) is used for performing text-based searches across multiple objects/ against the search index. It is designed to find records based on search terms in fields like text, email, or phone.

When you create a SOSL query, you start with the FIND clause. After that, you can add extra clauses to narrow down your search by object type, fields, data categories, and more. You can also decide what the query returns, like setting the order of the results and the number of rows you want to see.

Key Features of SOSL:

1. Used to search multiple objects simultaneously.
2. It returns the records ranked by relevance based on the search term.
3. Useful for global search when you are not sure in which object the data might be.

Examples of SOSL:

Syntax:  FIND {search Query} IN ALL FIELDS RETURNING Object__c(field1, field2).

FIND ‘Acme’ IN ALL FIELDS RETURNING Account (Name), Contact(Name, Email)

This search retrieves accounts and contacts that contain the keyword “Acme” in any searchable field.

Key Difference between SOQL and SOSL.

When to use SOQL?

Use SOQL when you are aware of the objects where the data is stored and need to:

• Fetch data from a single object or multiple related objects.
• Calculate the total number of records that match specific conditions.
• Sort results as part of the query.
• Retrieve data from number, date, or checkbox fields.

When to use SOSL?

Use SOSL when you are unsure of the object or field containing the data and need to:

• Search for a specific term within a field. SOSL leverages tokenization and search indexing, enabling faster and more relevant search results.
• Retrieve data from multiple objects and fields, even if the objects are unrelated.
• Access data for a specific division within an organization using the divisions feature.
• Search for data in languages such as Chinese, Japanese, Korean, or Thai.

Performance Consideration:

General searches can be slow and yield excessive results. To optimize text searches, use these clauses:

• IN: Restricts the search to specific field types, such as email, name, or phone.
• LIMIT: Defines the maximum number of rows to return, ensuring more efficient results.
• OFFSET: Displays the search results on multiple pages.
• RETURNING: Limits the objects and fields to return.
• WITH DATA CATEGORY: Specifies the data categories to return.
• WITH DivisionFilter: Specifies the division field to return.
• WITH NETWORK: Specifies the Experience Cloud site ID to return.
• WITH PricebookId: Specifies the price book ID to return.

SOQL Relationship Query:

1. Child to Parent Relationship Query.

Query: SELECT Contact.FirstName, Contact.Account.Name from Contact.

This query retrieves the first names of all contacts in the organization along with the account name linked to each contact as its parent.

2. Parent-to-child relationship Query.

The query:

SELECT Account.Name, (SELECT Contact.FirstName, Contact.LastName FROM Account.Contacts) FROM Account

retrieves all accounts in the organization and, for each account, it fetches the first and last names of all contacts associated as children of that account.

Conclusion

Both SOQL and SOSL are powerful tools in the Salesforce ecosystem, each tailored for distinct tasks. While SOQL is your go-to for precise and structured queries, SOSL shines in scenarios where broad and text-based searches are required. Mastering both ensures you can query data efficiently and adapt to varying business requirements.
