sql错误SyntaxException preparedstatement

标签: mysql sql

我正在使用PreparedStatement来执行SQL查询。这是查询。

select * from DEVICES WHERE device_id in (?,?,?,?)

这是我得到的错误

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: 
You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right 
syntax to use near '?,?,?,?)' at line 1

我在这里做错了什么?

这是捕获的Stacktrace。看起来我在执行查询时出错(这是合乎逻辑的)。

答案 0 :(得分:0)

噢,这是个错误...

我正在使用

ResultSet resultSet = statement.executeQuery(query);

我应该一直在使用

ResultSet resultSet = statement.executeQuery();

我现在工作了!
