我在查詢CSV文件（使用relique CsvDriver）時收到以下錯誤消息。java.sql.SQLException：語法錯誤
java.sql.SQLException：語法錯誤。遇到「，「集團 」「 第1行，列105 期待之一： 」和「 ... 」OR「 ...... 」訂單「 ...... 」限制「 ...
這裏是我的代碼
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);
產生下面的SQL語句
SELECT TRASH_TYPE AS trash_type, COUNT(TRASH_TYPE) AS num FROM trashed WHERE TRASH_DATE LIKE '1-%-2014' GROUP BY TRASH_TYPE
最後這是整個錯誤消息
java.sql.SQLException: Syntax Error. Encountered " <NAME> "GROUP "" at line 1, column 105.
Was expecting one of:
<EOF>
"AND" ...
"OR" ...
"ORDER" ...
"LIMIT" ...

這個問題可以解釋嗎？
如果您將該SQL語句直接在數據庫上運行，它是否會生成相同的錯誤？ –
請查看[預準備語句]（http://stackoverflow.com/questions/8263371/how-prepared-statements-can-protect-from-sql-injection-attacks）而不是串聯字符串並引入SQL注入漏洞。 –
沒有WHERE子句可以工作嗎？它沒有GROUP BY子句嗎？如果其中一個工作，另一個不工作，則可以更輕鬆地找到錯誤。 – agad
