Use the Salesforce Object Query Language (SOQL) to search your organization’s Salesforce data for specific information. With this information, we can fine-tune our queries for speed and performance.

The phases involved in the logical processing of an SQL query are as follows: In SQL, the first clause that is processed is the FROM clause, while the SELECT clause, which appears first in an SQL query, is processed much later. This is especially true with large and complex queries where knowing the order of execution can save us from unwanted results, and help us create queries that execute faster.Ĭonsider the SQL SELECT statement syntax: For a comparison of this functionality set click hereĭisclaimer: All product and company names are trademarks ™ or registered ® trademarks of their respective holders.Knowing the order in which an SQL query is executed can help us a great deal in optimizing our queries.
