多列搜索

Question

我目前使用2个单独的搜索，两个工作都很好。 但我不知道如何加入2？

结果我后，IF col1 contains word1和col2 contains word2

COL1包含单个单词，COL2包含多个单词。

这些是2个单独的查询，可以自行工作。

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+"%" };
