sqliteHow do I add a column to a SQLite database?
To add a column to a SQLite database, you must use the ALTER TABLE statement. This statement allows you to add, delete, or modify columns in an existing table.
For example, to add a new column called 'PhoneNumber' to the 'Employees' table:
ALTER TABLE Employees
ADD COLUMN PhoneNumber VARCHAR(20);The above statement will add a new column called PhoneNumber to the Employees table with a data type of VARCHAR(20), which is a string of up to 20 characters.
The parts of the statement are:
ALTER TABLE: This is the statement that tells SQLite to modify an existing table.Employees: This is the name of the table that you want to modify.ADD COLUMN: This tells SQLite to add a new column to the table.PhoneNumber: This is the name of the new column that you are adding.VARCHAR(20): This is the data type of the new column.
No output will be generated by this statement.
