Example
// You need a writable database to update a row
final SQLiteDatabase database = openHelper.getWritableDatabase();
// Create a ContentValues instance which contains the up to date data for each column
// Unlike when inserting data you need to specify the value for the PRIMARY KEY column as well
final ContentValues values = new ContentValues();
values.put(COLUMN_ID, model.getId());
values.put(COLUMN_NAME, model.getName());
values.put(COLUMN_DESCRIPTION, model.getDescription());
values.put(COLUMN_VALUE, model.getValue());
// This call performs the update
// The return value tells you how many rows have been updated.
final int count = database.update(
TABLE_NAME, // The table name in which the data will be updated
values, // The ContentValues instance with the new data
COLUMN_ID + " = ?", // The selection which specifies which row is updated. ? symbols are parameters.
new String[] { // The actual parameters for the selection as a String[].
String.valueOf(model.getId())
}
);
