## What it does
**SQL Update Statement**
==========================

### Purpose
The provided SQL update statement is used to modify existing records in the `Util Selection C1` table by setting the `Flag` column to a value of `"1"`.

### Syntax Breakdown
```sql
UPDATE [Util Selection C1]
SET [Util Selection C1].Flag = "1"
WHERE ((([Util Selection C1].USAGE)=0));
```

*   **UPDATE**: This keyword is used to update existing records in the specified table.
*   **[Util Selection C1]**: The target table, `Util Selection C1`, where the data will be modified.
*   **SET [Util Selection C1].Flag = "1"**: Specifies that the value of the `Flag` column for each record in the table should be updated to `"1"`.
    *   \[Util Selection C1\] refers to the table itself, and this indicates that we are setting the value of a specific column within that table.
    *   `.Flag` is an alias for the `Flag` column, allowing us to access it by its name instead of its full path.
*   **WHERE ((([Util Selection C1].USAGE)=0))**: Applies conditions to filter which records should be updated. Only rows where the condition specified in the WHERE clause are true will be updated.

### Condition Explanation
The `WHERE` clause applies a filtering condition:

*   \(([Util Selection C1].USAGE) = 0\) means that only records with a value of `0` for the `USAGE` column should be updated.
    *   This implies that records with non-zero values in the `USAGE` column are not updated by this SQL statement.

### Example Use Case
Consider that you have a database containing information about different utility services, where each service is associated with a unique identifier (`USAGE`) and has an optional flag indicating whether it's enabled or disabled. This update statement can be used to mark all unused (i.e., `USAGE = 0`) services as active (`Flag = "1"`), effectively toggling their status from inactive to active.

### Note
This code is case-sensitive due to the use of square brackets around table and column names, which are often required in SQL for proper syntax.
