an existing column in a table created in the SQLite database

The SQLite RENAME COLUMN TO
keyword changes the name of the existing column with a new name. To rename a column, use the ALTER TABLE
command followed by the RENAME COLUMN TO keyword. To better understand, follow the RENAME COLUMN TO syntax below.

followed by the new name of the column.
