Android SQL查询带有两个"Where"子句

Question

您好我有一个SQL查询,我希望它有两个WHERE子句.我希望它在我的数据库中查询Bid和Cid并将其返回到游标,我的代码

     public Cursor getSubCategoriesQuerybyCidandBid(String Cid, int Bid) {
        this.openDataBase();
        Cursor c;
         String[] asColumnsToReturn = new String[] {SECOND_COLUMN_ID, SECOND_COLUMN_IDENTITY, SECOND_COLUMN_SUBCATEGORIES};
         c =dbSqlite.query(false, TABLE_NAME, asColumnsToReturn, COLUMN_BID + "=" + Bid + COLUMN_CID + "=" + Cid , null, null, null, null, null);
         return c;
    }

这就是我想要它的方式,但这不是任何想法如何解决这个问题？

Answer 1

试试COLUMN_BID + "=" + Bid + " AND " + COLUMN_CID + "=" + Cid.
