What are the differences between using COPY in PostgreSQL and LOAD DATA in MySQL for importing CSV files into a database table?

When importing CSV files into a database table, the main difference between using COPY in PostgreSQL and LOAD DATA in MySQL is the syntax and specific options each command offers. COPY in PostgreSQL is a SQL command that allows for efficient bulk data loading from a CSV file, while LOAD DATA in MySQL is a statement that can be used within a SQL script to import data from a CSV file. Additionally, COPY in PostgreSQL requires the file path to be accessible by the database server, while LOAD DATA in MySQL can load files from the client-side.

// PostgreSQL using COPY command
$db = pg_connect("host=localhost dbname=mydb user=myuser password=mypassword");
$query = "COPY mytable FROM '/path/to/myfile.csv' CSV HEADER";
$result = pg_query($db, $query);

// MySQL using LOAD DATA command
$db = mysqli_connect("localhost", "myuser", "mypassword", "mydb");
$query = "LOAD DATA INFILE '/path/to/myfile.csv' INTO TABLE mytable FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\n' IGNORE 1 LINES";
mysqli_query($db, $query);
