Question
Write a query to change the type of field owner_name in the building table to varchar(500).
ALTER TABLE building
MODIFY owner_name VARCHAR(500);
Solution
To change the type of field 'owner_name' in the 'building' table to varchar(500), you can use the ALTER TABLE statement in SQL. Here is the step-by-step process:
-
Open your SQL database management system.
-
Connect to the database where the 'building' table is located.
-
Run the following SQL command:
ALTER TABLE building
ALTER COLUMN owner_name TYPE varchar(500);
This command will change the data type of the 'owner_name' column in the 'building' table to varchar(500). Please make sure to replace 'building' and 'owner_name' with your actual table and column name if they are different.
Remember to be careful when altering tables, as it can affect the data stored in the table. Always make sure to backup your data before making such changes.
