In some databases, such as Postgre SQL, when a FROM clause is present, what essentially happens is that the target table is joined to the tables mentioned in the fromlist, and each output row of the join represents an update operation for the target table.When using FROM, one should ensure that the join produces at most one output row for each row to be modified.resize=300,212 300w, https://i0com/tech-mirror.com/wp-content/uploads/2017/06/sql-update.jpg? w=740 740w" sizes="(max-width: 380px) 100vw, 380px" data-recalc-dims="1" So, if we do not specify the WHERE clause, then all rows get changed its values.
