Question

Maybe this is a “simple” question but I have this method:

public int getMaxColumnData() {
    bdd = maBaseSQLite.getWritableDatabase();
    final SQLiteStatement stmt = bdd
                .compileStatement("SELECT MAX(column) FROM Table");
    return (int) stmt.simpleQueryForLong();
}

and I would like to do this int i = getMaxColumnData();

And that throws an error.

My goal is to find the maximum of a column in the database table.

Here is the error:

Cannot make a static reference to the non-static method getMaxColumnData() from the type CapteursBDD

Answer 1

EDIT: the problem is probably because bdd is declared as static whereas the method in which you use bdd is not static.

Changing the method signature to public static int getMaxColumnData() might solve your problem.
