sqliteHow do I use SQLite REPLACE to update existing records in a database?

SQLite REPLACE is used to update existing records in a database. It is similar to the SQL UPDATE command, but with REPLACE, you can update a record if it already exists, or insert a new record if it does not exist.

The syntax for REPLACE is as follows:

REPLACE INTO table_name (column1, column2, ...)
VALUES (value1, value2, ...);

For example, if we wanted to update the name of an existing record in a table called "customers", we could use the following command:

REPLACE INTO customers (id, name)
VALUES (1, 'John Doe');

This command would update the name of the customer with an ID of 1 to "John Doe". If there was no record with an ID of 1, then a new record would be inserted.

The parts of the REPLACE command are:

• REPLACE INTO: This is the keyword for the command.
• table_name: This is the name of the table to be modified.
• column1, column2, ...: This is a list of the columns to be modified.
• VALUES: This is the keyword that indicates the values to be inserted or updated.
• value1, value2, ...: This is a list of values to be inserted or updated.
