Updating Data

The following code examples show how to use data modification statements.

Procedure for Updates

You can use separate statements to execute data modification statements. Once you create the statement, you can call its executeNonQueryMethod and retrieve the number of affected rows.

INSERT

To insert updates:

db.open("...", (err) => {
    db.prepare("INSERT INTO Customers(Company) VALUES ('John')", (err, stmt) => {
        stmt.executeNonQuery((err, affected) => {
            console.log("Affected: " + affected);
        });
    });
});

UPDATE

To retrieve updates:

db.open("...", (err) => {
    db.prepare("UPDATE Customers SET Company = 'John' WHERE CustNum = 'CompanyName'", (err, stmt) => {
        stmt.executeNonQuery((err, affected) => {
            console.log("Affected: " + affected);
        });
    });
});

DELETE

To delete updates:

db.open("...", (err) => {
    db.prepare("DELETE FROM Customers WHERE Id = '12345'", (err, stmt) => {
        stmt.executeNonQuery((err, affected) => {
            console.log("Affected: " + affected);
        });
    });
});
