In this first post, I’ll introduce the basics of SOQL statements, including these concepts and keywords: SELECT, FROM, LIMIT, ORDER BY, basic WHERE conditions, and basic operators.

Loads the new record field values from the request and overwrites the old values. If the request came from a standard UI edit page, Salesforce runs system validation to check the record for: Compliance with layout-specific rules Required values at the layout level and field-definition level Valid field formats Maximum field length When the request comes from other sources, such as an Apex application or a SOAP API call, Salesforce validates only the foreign keys.
