**SQL Update Statement Description**
|
|
=====================================
|
|
|
|
### Overview
|
|
|
|
The provided SQL update statement modifies specific data in the `Process` table.
|
|
|
|
### Syntax
|
|
|
|
```sql
|
|
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.
