User: User: Help me write a SQL statement that grants only update access on a specific table in a database for a specific user group. 
Assistant: To grant update access on a specific table for a specific user or user group, you can use the SQL `GRANT` statement. The precise syntax can vary slightly depending on the database management system you are using, but the general form would be:

```sql
GRANT UPDATE ON table_name TO user_group;
```

Here's a step-by-step explanation:

- **`UPDATE`**: This is the type of access you're granting. It allows users to modify data in the table.
- **`ON table_name`**: Replace `table_name` with the actual name of your table.
- **`TO user_group`**: Replace `user_group` with the name of the user or user group you want to grant the privilege to.

Here's an example for a table named `employees` and a user group named `marketing_team`:

```sql
GRANT UPDATE ON employees TO marketing_team;
```

Please note:

1. The ability to grant permissions can depend on your own privileges in the database system. Typically, only database administrators or the owner of the table can grant privileges.

2. Some database systems might require more specific syntax for groups versus individual users. For example, in PostgreSQL, roles are often used to manage groups.

3. This statement doesn't explicitly handle cases where you need to create the user group or ensure it exists; it’s assumed that `marketing_team` already exists in the database.

Make sure to adjust the SQL statement as needed for your specific database system, as there could be differences in syntax or functionality.
User: Okay, great. How do you do this as a stored procedure instead?
Assistant: Creating a stored procedure to grant update access on a specific table for a specific user group can be a great way to encapsulate this logic for reuse. Below is an example of how you might write such a stored procedure in SQL. The syntax can vary depending on the database system you are using, but here’s a general example for a SQL Server environment:

```sql
CREATE PROCEDURE GrantUpdateAccess
    @TableName NVARCHAR(128),
    @UserGroup NVARCHAR(128)
AS
BEGIN
    DECLARE @SQL NVARCHAR(MAX);
    
    SET @SQL = 'GRANT UPDATE ON ' + QUOTENAME(@TableName) + ' TO ' + QUOTENAME(@UserGroup) + ';';
    
    EXEC sp_executesql @SQL;
END;
```

### Explanation:

1. **Procedure Name**: The procedure is named `GrantUpdateAccess`.
2. **Parameters**: It takes two parameters:
   - `@TableName`: The name of the table you want to grant access to.
   - `@UserGroup`: The name of the user group you want to grant access to.
3. **Dynamic SQL**: The procedure constructs a dynamic SQL statement that grants update access. It uses `QUOTENAME` to safely handle table and user group names, preventing SQL injection.
4. **Execution**: The `sp_executesql` system stored procedure is used to execute the dynamic SQL.

### Example Usage:

To use this stored procedure, you would call it like this:

```sql
EXEC GrantUpdateAccess 'employees', 'marketing_team';
```

### Note:

- Make sure that the user executing this stored procedure has the necessary permissions to grant access on the specified table.
- Adjust the syntax as needed for your specific database system, as the approach may differ slightly in systems like MySQL, PostgreSQL, or Oracle.
User: I've changed my mind, I don't want to insert it as direct updates, I'd rather create a stored procedure that does the update I want in a safe manner for any users. If I give you the update, can you help me write the stored procedure for it?
