【中文标题】java.sql.SQLException：语法错误

【英文标题】：java.sql.SQLException: Syntax Error

【发布时间】：2015-01-14 14:28:35

【问题描述】：

当我查询 CSV 文件（使用 relique CsvDriver）时，我在下面收到此错误消息。

。在第 1 行第 105 列遇到““GROUP”。 期待其中之一： “和” ... “或者” ... “命令” ... “限制” ...

这是我的代码

Class.forName("org.relique.jdbc.csv.CsvDriver");

Connection conn = DriverManager.getConnection("jdbc:relique:csv:" + mgrDir);

Statement stmt = conn.createStatement();

String query = "SELECT TRASH_TYPE AS trash_type, COUNT(TRASH_TYPE) AS num FROM " + src_file + " WHERE TRASH_DATE LIKE '" + query_date + "' GROUP BY TRASH_TYPE";

ResultSet results = stmt.executeQuery(query);

产生以下 SQL 语句

SELECT TRASH_TYPE AS trash_type, COUNT(TRASH_TYPE) AS num FROM trashed WHERE TRASH_DATE LIKE '1-%-2014' GROUP BY TRASH_TYPE

最后这是整个错误信息

java.sql.SQLException: Syntax Error. Encountered " <NAME> "GROUP "" at line 1, column 105.
Was expecting one of:
<EOF> 
"AND" ...
"OR" ...
"ORDER" ...
"LIMIT" ...

有什么可以说明这个问题的吗？

【问题讨论】：

如果您使用该 SQL 语句并直接在您的数据库上运行它，是否会产生同样的错误？

请查看prepared statements，而不是连接字符串并引入 SQL 注入漏洞。

没有 WHERE 子句是否可以工作？如果没有 GROUP BY 子句，它可以工作吗？如果其中一个有效而另一个无效，您可以更轻松地找到错误。

去掉WHERE子句就更奇怪了。我收到以下错误消息。 。在第 1 行第 78 列遇到“BY”“BY”。期待以下之一：“WHERE”...“ORDER”...“LIMIT”...

【参考方案1】：

这似乎是我使用的 csvjdbc 版本的问题。我用 1.0-18 版本尝试了相同的代码，它运行良好。

有没有人听说过这样的错误（？）？
