sqliteHow do I alter a table in SQLite?
To alter a table in SQLite, you use the ALTER TABLE statement. This statement allows you to add, remove, or modify columns in an existing table.
For example, to add a new column named date_created to the customers table, you use the following statement:
ALTER TABLE customers
ADD COLUMN date_created DATE;This statement adds a new column named date_created to the customers table. The column is of type DATE, which stores date and time values.
You can also use the ALTER TABLE statement to modify the data type of an existing column, rename an existing column, or drop an existing column.
For example, to modify the data type of the date_created column to TEXT, you use the following statement:
ALTER TABLE customers
MODIFY COLUMN date_created TEXT;To rename the date_created column to created_at, you use the following statement:
ALTER TABLE customers
RENAME COLUMN date_created TO created_at;To drop the created_at column, you use the following statement:
ALTER TABLE customers
DROP COLUMN created_at;More information about the ALTER TABLE statement can be found in the SQLite documentation.
