What it does

SQL Update Statement Description

Overview

The provided SQL update statement modifies specific data in the Process table.

Syntax

UPDATE Process 
SET Process.MetalType = "8111114" 
WHERE (((Process.MetalType) = "8110022"));

Breakdown

Table Name and Column Name

• The table being updated is named Process.
• The column being modified is also named MetalType.

Update Clause

• The keyword UPDATE indicates that this statement modifies existing data in the database.
• The SET Process.MetalType = "8111114" clause specifies the new value for the MetalType column. In this case, it updates all records to have a metal type of "8111114".

WHERE Clause

• The keyword WHERE is used to specify conditions under which the update should be applied.
• The condition (Process.MetalType) = "8110022" filters the rows that will be updated. Only records with a current value of "8110022" in the MetalType column will be affected by this update.

Subquery

• The use of parentheses around the subquery (Process.MetalType) = "8110022" indicates that it is an inner subquery, not an aggregate or correlated subquery. This means the outer query can only use the value of MetalType once.

Effectiveness

This SQL statement will update all rows in the Process table where the current MetalType is "8110022", changing its value to "8111114". If there are multiple conditions being applied, this would be an OR operation.
