QueryQQ3Write a query to change the route_name from 'East West line' to 'South West line' in the 'route' table.

To change the route_name from 'East West line' to 'South West line' in the 'route' table, you would use the SQL UPDATE statement. Here is a step-by-step guide on how to do it:

1. Open your SQL database management system and connect to the database that contains the 'route' table.

2. Once you're connected, you can use the SQL UPDATE statement to change the route_name. The UPDATE statement is used to modify the existing records in a table.

3. The syntax for the SQL UPDATE statement is:

UPDATE table_name
SET column1 = value1, column2 = value2, ...
WHERE condition;

4. In your case, you want to change the route_name from 'East West line' to 'South West line'. So, your SQL query would look like this:

UPDATE route
SET route_name = 'South West line'

To change the route_name from 'East West line' to 'South West line' in the 'route' table, you would use the SQL UPDATE statement. Here is a step-by-step guide on how to do it:

1. First, you need to identify the table you want to update. In this case, it's the 'route' table.

2. Next, you need to specify the column you want to update. Here, it's the 'route_name' column.

3. Then, you need to specify the new value you want to set for the column. Here, you want to change 'East West line' to 'South West line'.

4. Finally, you need to specify the condition for the rows that should be updated. In this case, you want to update the rows where 'route_name' is 'East West line'.

Here is the SQL query that does all of this:

UPDATE route
SET route_name = 'South West line'
WHERE route_name = 'East West line';

This query will update the 'route_name' to 'South West line' for all rows in the 'route' table where the current 'route_name' is 'East West line'.
