我在查询CSV文件（使用relique CsvDriver）时收到以下错误消息。java.sql.SQLException：语法错误
java.sql.SQLException：语法错误。遇到“，“集团 ”“ 第1行，列105 期待之一： ”和“ ... ”OR“ ...... ”订单“ ...... ”限制“ ...
这里是我的代码
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);
产生下面的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
最后这是整个错误消息
java.sql.SQLException: Syntax Error. Encountered " <NAME> "GROUP "" at line 1, column 105.
Was expecting one of:
<EOF>
"AND" ...
"OR" ...
"ORDER" ...
"LIMIT" ...

这个问题可以解释吗？
如果您将该SQL语句直接在数据库上运行，它是否会生成相同的错误？ –
请查看[预准备语句]（http://stackoverflow.com/questions/8263371/how-prepared-statements-can-protect-from-sql-injection-attacks）而不是串联字符串并引入SQL注入漏洞。 –
没有WHERE子句可以工作吗？它没有GROUP BY子句吗？如果其中一个工作，另一个不工作，则可以更轻松地找到错误。 – agad
