SOQL vs SOSL and When to Use Them

Salesforce has a query language called SOQL, or Salesforce Object Query Language. It is similar, from a syntactical point of view to SQL and allows for querying the database of an organization.

However, there will be cases where the Salesforce query language is not sufficient. This is where Salesforce’s object search language comes into play; it is called SOSL, or Salesforce Object Search Language.

Below, I will provide a brief introduction to each of these languages and then delve into the appropriate use cases for different types of queries or searches. If you handle data in Salesforce, it is important to know both languages and understand when to use the appropriate one.

Definitions

SOQL (Salesforce Object Query Language):

This is Salesforce’s query language, used to query and retrieve data from objects in the platform’s database. It has a syntax very similar to SQL, making it easier for those who are already familiar with it to learn.

SOSL (Salesforce Object Search Language):

This is Salesforce’s search language, used to perform text searches across the organization’s records. Its main difference from SOQL lies in that it queries a search index that Salesforce automatically generates and maintains.

Query Editor:

This is a tool within the Developer Console, where SOQL and SOSL queries can be written and executed.

Search Index:

This is a structure used by SOSL searches to evaluate keywords and return data efficiently. This tool stores information about user search behavior, allowing results to become more personalized and accurate as the user interacts more with the search engine.

Fundamental Concepts

SOQL Query:

A SOQL query is used when you want to obtain structured and specific data from an object and its related objects in Salesforce. It is ideal for performing queries that require specific filtering and retrieval of related data.

SOSL Search:

A SOSL search is more appropriate when you need to perform full-text searches across multiple objects and fields simultaneously. It is ideal for finding records that contain specific words in any field and any object.

Details, Interesting Data, and Related Examples

Syntax

• SOQL:

SELECT Fields FROM Object WHERE Condition

• Fields: A list of one or more fields to be retrieved.
• Object: The name of the object from which the data is retrieved.
• Condition: Optional. A clause that specifies the criteria for filtering records. It uses operators like =, !=, <, >, LIKE, IN, etc., to define the conditions.

Example:

SELECT Id, Name, Email FROM Contact WHERE Email LIKE ‘%@example.com’

• SOSL:

FIND ‘SearchQuery’ [IN SearchGroup] [RETURNING ObjectsAndFields]

• SearchQuery: The text to search for, which can be a word or a phrase.
• SearchGroup: Optional. Defines the scope of the search fields. If not specified, all fields are included. Options include:
  • ALL FIELDS: All fields
  • NAME FIELDS: Name fields
  • EMAIL FIELDS: Email fields
  • PHONE FIELDS: Phone fields
• ObjectsAndFields: Optional. Specifies the information to return as a result of the search. It consists of a list of one or more objects (sObjects) and, within each object, a list of one or more fields. If not specified, the search result will contain the IDs of all objects found.

Example:

FIND ‘Technology’ IN ALL FIELDS RETURNING Account(Id, Name)

SOSL in the Query Editor vs. in Apex:

It is important to note that the SOSL syntax varies slightly when the search is done from the Query Editor and in Apex.

• SOSL in Apex:
• FIND ‘Donut’ IN ALL FIELDS
• SOSL in the Query Editor:
• FIND {Donut} IN ALL FIELDS

Use Cases

SOQL Use Cases:

• Retrieve records from a specific object with precise conditions.
• Perform joins between related objects to obtain combined data.
• Generate reports based on specific data.

Examples:

• Get all contacts associated with a specific account:
• SELECT Name FROM Contact WHERE AccountId = ‘001XXXXXXXXXXXXXXX’
• Retrieve closed opportunities in the last quarter:
• SELECT Name, Amount FROM Opportunity WHERE CloseDate = LAST_QUARTER AND IsClosed = true

SOSL Use Cases:

• Perform quick full-text searches across multiple objects.
• Find records when only part of the text or a keyword is available.
• Conduct global searches in Salesforce.

Examples:

• Search for records containing the word “Project” in any field:
• FIND {Project} IN ALL FIELDS RETURNING Account(Id, Name), Contact(Id, Name)
• Search for all records related to “Marketing”:
• FIND {Marketing} RETURNING Account(Id, Name), Opportunity(Id, Name)

Benefits and Applications

Benefits of SOQL:

• Precision in queries.
• Ability to perform complex and nested queries.
• Ideal for reporting.

Benefits of SOSL:

• Speed in full-text searches.
• Ability to search across multiple objects and fields simultaneously.
• Ideal for global searches and when partial information is available.

Challenges and Solutions

SOQL Challenges:

• Less efficient for full-text searches.
• Must know the specific field and object from which to retrieve information.

Solutions:

• Use appropriate filters.
• Understand the complete information desired.

SOSL Challenges:

• Less precise for specific and filtered queries.
• Does not support complex join operations.

Solutions:

• Combine with SOQL for specific queries.
• Define clear and specific search criteria.

Conclusión

Recap of Key Points:

• SOQL and SOSL are powerful tools for managing data in Salesforce.
• SOQL is ideal for precise and structured queries.
• SOSL is excellent for full-text and global searches, especially when you do not know where the desired information is located.
• Knowing when to use each can optimize data management and improve query efficiency.

Invitation to Reflect:

Reflect on your querying and searching needs in Salesforce. Are you using the appropriate language for each case? Experiment with both languages to see how they can enhance your data management processes.
