Question

我使用fts3创建了一个表格。我使用以下查询来获得结果

      String query = "SELECT "+ID+" as _id," + 
        NAME +  
        " from " + TABLENAME +
        " where " +  NAME + " MATCH '" + inputKeyword + "';";
        Log.w(TAG, query);

其中列出了基于inputKeyword。

的名称列表

但它不适用于多列，

    String query = "SELECT "+ID+" as _id," + 
        NAME +  
        " from " + TABLENAME +
        " where " +  NAME + " MATCH '" + inputKeyword + "' AND "+ EMAILADDRESS + " MATCH '"+emailaddress+"';";

这不会给出任何结果，并且还说您无法在此查询中使用MATCH。怎么做？

Answer 1

您的查询如下所示：

SELECT ID as _id, Name
FROM TableName
WHERE Name MATCH 'xxx' AND EmailAddress'yyy'

这缺少第二列的MATCH运算符。你想要的应该是这样的：

SELECT ID as _id, Name
FROM TableName
WHERE TableName MATCH 'Name:xxx EmailAddress:yyy'

Answer 2

显然sqlite不支持将OR查询与MATCH条件相结合。工会工作

SELECT  *
FROM    email_fts 
WHERE   "to" MATCH 'a@b.com'

UNION

SELECT  *
FROM    email_fts 
WHERE   "from" MATCH 'c@d.com'

如何在SQLite中为多列使用MATCH Keyword？
