SQL选择表中从特定日期到特定日期的所有值

Question

我不想从表中选择COLUMN_DATUM＆gt;的所有值。 int fran＆amp;＆amp; COLUMN_DATUM＆lt;直到这基本上意味着从表中选择日期＆gt;来自＆amp;＆amp;日期＆lt;至。

Under是应该执行SQL批处理的方法。

public Cursor getAllItemsByDate(int fran, int till) {
        //CODE to return everything in the table TABLE_UTGIFTER ->
        //where COLUMN_DATUM > fran && COLUMN_DATUM < till.
}

全班供参考。
