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 Spreadsheet1_Sheet1 (Column1) VALUES ('John')", (err, stmt) => {
        stmt.executeNonQuery((err, affected) => {
            console.log("Affected: " + affected);
        });
    });
});

UPDATE

To retrieve updates:

db.open("...", (err) => {
    db.prepare("UPDATE Spreadsheet1_Sheet1 SET Column1 = 'John' WHERE Id = 'Bob'", (err, stmt) => {
        stmt.executeNonQuery((err, affected) => {
            console.log("Affected: " + affected);
        });
    });
});

DELETE

To delete updates:

db.open("...", (err) => {
    db.prepare("DELETE FROM Spreadsheet1_Sheet1 WHERE Id = '6'", (err, stmt) => {
        stmt.executeNonQuery((err, affected) => {
            console.log("Affected: " + affected);
        });
    });
});
