Android sqlite 查询与 AND

Question

我想问你如何进行如下查询:

select * from table where id = 1 AND year = 1999

Android中用sqlite的命令查询？ 提前致谢

Answer 1

只需将“AND”添加到第三个参数(字符串选择):

database.query(TABLE_NAME, new String[]{COLUMN_1, COLUMN_2},
               COLUMN_1 + " = ? AND " + COLUMN_2 + " = ? ", new String[]{value1, value2}, null, null, null);

就您而言，COLUMN_1 是 id，COLUMN_2 是 year，value1 > 是“1”，value2 是“1999”。
