sqliteHow do I use UUIDs in SQLite?
UUIDs (Universally Unique Identifiers) can be used in SQLite to create a unique identifier for each row in a table. To use UUIDs in SQLite, you first need to create a table with a column to store the UUIDs. The following example creates a table named
users with a column named
uid to store the UUIDs:
CREATE TABLE users (
uid UUID PRIMARY KEY,
Then you can insert UUIDs into the table using the
uuid() function. The following example inserts a row with a new UUID into the
INSERT INTO users (uid, name) VALUES (uuid(), 'John Doe');
uuid() function generates a version 4 UUID, which is composed of random numbers and letters.
CREATE TABLE- creates a table with the specified columns and data types
UUID- the data type used to store the UUIDs
PRIMARY KEY- ensures that each row has a unique identifier
INSERT INTO- inserts a row into the specified table
uuid()- generates a new version 4 UUID
