How to Handle SQLite's 'UNIQUE constraint failed' Error When Inserting Data?

SQLite Error: "UNIQUE constraint failed: Persons.id"

When inserting data into a SQLite database, you may encounter the "UNIQUE constraint failed" error. This error occurs when you attempt to insert a row into a table where a column has a UNIQUE constraint and the value for that column already exists in the table.

In the provided code, the error is caused by the attempts to insert duplicate values for the id field in the user table, the list_id field in the list table, and the item_id field in the item table.

To resolve this error, you have several options:

• Ignore the error: If you want SQLite to continue inserting rows even if some of them violate the UNIQUE constraint, you can use the INSERT OR IGNORE syntax, as follows:

INSERT OR IGNORE INTO user (user_id, first_name, title, username, password, email, bio)
