In SQL, which command is used to change a table’s storage characteristics?

The command used to change a table's storage characteristics in SQL is ALTER TABLE. Here are the steps to use it:

1. First, you need to specify the table name that you want to change.

ALTER TABLE table_name

2. Then, you specify the changes you want to make. For example, if you want to add a new column, you would use the ADD COLUMN command:

ALTER TABLE table_name
ADD COLUMN column_name column_type;

3. If you want to change the data type of a column, you would use the ALTER COLUMN command:

ALTER TABLE table_name
ALTER COLUMN column_name TYPE new_data_type;

4. To change the storage characteristics specifically, you would use the SET command. For example, to change the table to use a different tablespace:

ALTER TABLE table_name
SET TABLESPACE new_tablespace;

Remember to replace table_name, column_name, column_type, new_data_type, and new_tablespace with your actual table name, column name, column type, new data type, and new tablespace respectively.
