java - 将数据插入DB android时出错

问题描述

我在数据库中有两个表，条目只有列词，另一个表 worddictionary 有列词、定义和 auduiourl，

 String create_table_query = "CREATE TABLE `entries` (`word` varchar(50) NOT NULL)";
 db.execSQL(create_table_query);

 String create_word_table = "CREATE TABLE `worddictionary` (`word` TEXT NOT NULL,'definition' TEXT, 'audiourl' TEXT)";
 db.execSQL(create_word_table);

我正在尝试将使用网络抓取获得的单词、其定义和 audiourl 插入 worddictionary 表中，

 String insert_query = "INSERT INTO worddictionary values("+word+","+wordDefinition+","+audioUrl+")";
 db.execSQL(insert_query);

但我得到以下错误，

在这个错误中，在“大”附近提到了错误，即定义中的词我不明白错误是什么

解决方案

这可能是因为周围的标记word不同definition吗？

我替换的那个人使用了 Content 值，所以对你来说它是

ContentValues values = new ContentValues();
values.put("word", word);
values.put("definition", definition);
values.put("audiourl", audiourl);

db.insert("worddictionary", null, values);
