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 Sheet_Test_Sheet (Name) VALUES ('Basic Agile Project with Gantt Timeline')", (err, stmt) => {
        stmt.executeNonQuery((err, affected) => {
            console.log("Affected: " + affected);
        });
    });
});

UPDATE

To retrieve updates:

db.open("...", (err) => {
    db.prepare("UPDATE Sheet_Test_Sheet SET Name = 'Basic Agile Project with Gantt Timeline' WHERE Id = 'True'", (err, stmt) => {
        stmt.executeNonQuery((err, affected) => {
            console.log("Affected: " + affected);
        });
    });
});

DELETE

To delete updates:

db.open("...", (err) => {
    db.prepare("DELETE FROM Sheet_Test_Sheet WHERE Id = '123456'", (err, stmt) => {
        stmt.executeNonQuery((err, affected) => {
            console.log("Affected: " + affected);
        });
    });
});
