多列搜索

Question

我目前正在使用2个单独的搜索，两者都可以自行完成。 但我无法弄清楚如何加入2？

结果我在IF col1 contains word1和col2 contains word2

之后

col1包含单个单词，col2包含多个单词。

这两个单独的查询可以自行运行。

String selection = col1+ " LIKE ?";
String[] selection_args = {word1};
Cursor cursor = sqlitedatabase.query(TABLE_NAME, All_Cols, selection, selection_args, null, null, null);

String selection =  col2+ " LIKE ?";
String[] selection_args = {"%"+word2+"%"};
Cursor cursor = sqlitedatabase.query(TABLE_NAME, All_Cols, selection, selection_args, null, null, null);

Answer 1

加入他们。使用AND：

String selection = col1 + " LIKE ? AND " + col2 + " LIKE ?";
String[] selection_args = { word1, "%"+word2+"%" };
