Salesforce Object Query Language (SOQL) & Salesforce Object Search Language (SOSL) Questions

45. Can you explain what SOQL and SOSL are? 

Answer: The languages SOSL and QL (Salesforce Object Query Language and Salesforce Object Search Language, respectively) are used to create queries to extract data from Salesforce. SOQL retrieves specific fields and records, whereas SOSL is used for text-based searches across multiple objects.

46. SOSL v/s SOQL. Explain.

Answer: SOQL is great for detailed, field-level queries, while SOSL is better for broad-text searches. SOQL can retrieve related object data through relationship queries, but SOSL cannot.

47. How does Salesforce use SOQL and SOSL? 

Answer: Salesforce uses SOQL and SOSL to retrieve data from its database. This data can then be displayed to users, used in calculations, or used to trigger business processes.

48. What criteria would you use to decide whether to use SOSL or SOQL in a certain situation? 

Answer: If I need to retrieve specific fields or related records, I will use SOQL. If I need to perform a text search across multiple objects or areas, I will use SOSL.

49. The ‘WHERE’ clause in SOQL serves what function? 

Answer: The ‘WHERE’ clause in SOQL filters results based on specific conditions. It helps to retrieve only those records that meet certain criteria.

50. Can you explain how to use SOQL’s relationship queries? 

Answer: Relationship queries in SOQL let you retrieve data from related records. For example, if you wanted to retrieve the names of all contacts associated with a certain account, you could use a relationship query.

51. How would you write a SOSL query to search across multiple objects?

Answer: A SOSL query that searches across multiple objects could look like this: “FIND ‘John Doe’ IN ALL FIELDS RETURNING Account (Id, Name), Contact (FirstName, LastName, Email), Lead (Id, Name, Email).” This would return any accounts, contacts, or leads where ‘John Doe’ appears in any field.

52. What are the SOSL and SOQL restrictions?

Answer: Both SOQL and SOSL have governor limits to prevent excessive resource usage. SOQL is limited to returning 50,000 records in a single query. SOSL can search a maximum of 2,000 records at a time.
