Soql Interview Questions
SOQL, or Salesforce Object Query Language, is a powerful query language used to search records in Salesforce databases. In a SOQL interview, candidates may be asked questions related to querying and manipulating data in Salesforce, such as querying multiple objects, filtering data, sorting results, using aggregate functions, and working with relationships between objects. Interviewers may also test the candidate's understanding of SOQL syntax, best practices, and performance optimization strategies to assess their proficiency in extracting meaningful information from Salesforce databases. Familiarity with SOQL can be a valuable skill for candidates seeking roles that involve data analysis, reporting, or Salesforce development.

1 - What is SOQL and how is it different from SQL?
SOQL (Salesforce Object Query Language) is a language used to query records stored in Salesforce. While both SOQL and SQL are query languages, the key difference is that SOQL is specifically designed for querying Salesforce data and can only query records stored in Salesforce objects. SQL, on the other hand, is a standard language used to query data in relational databases.
2) How can you filter records in SOQL?
You can filter records in SOQL using the WHERE clause. This clause allows you to specify conditions that the records must meet to be returned in the query results. For example, you can filter records based on specific field values, relationships, or other criteria.
3) What are the different types of SOQL queries?
There are several types of SOQL queries, including basic queries, relationship queries, aggregate queries, and semi join and anti join queries. Basic queries retrieve records from a single object, relationship queries retrieve records from related objects, aggregate queries perform calculations on data, and semi join and anti join queries filter records based on related object values.
4) How can you retrieve all fields from an object in a SOQL query?
To retrieve all fields from an object in a SOQL query, you can use the wildcard (*) symbol. For example, SELECT * FROM ObjectName will return all fields from the specified object.
5) What is the difference between SOQL and SOSL?
SOQL (Salesforce Object Query Language) is used to query records stored in Salesforce objects, while SOSL (Salesforce Object Search Language) is used to perform text searches in Salesforce data. SOQL is used for querying structured data within Salesforce objects, while SOSL is used for searching unstructured data across multiple objects.
