Java SQL查询在MySql工作台中执行，但不在生产环境中执行

有问题的SQL查询：

选择COUNTsuggestedfood.id作为num_same，suggestedfood.place_id FROM suggestedfood WHERE suggestedfood.group_id=？和建议的食物。选定=？和建议的食物。删除=？按建议食物分组。地点\ id限制1

此查询可以在MySQL Workbench中运行，但在生产中会引发以下错误：

您的SQL语法有错误；检查与您的MySQL服务器版本对应的手册，以了解使用接近“”的正确语法？和建议的食物。选定=？和建议的食物。删除=？在第1行按建议的“foo”分组

MySQL错误代码：1064

MySQL状态：42000

MySQL服务器在AWS RDS上，如果这有帮助的话，我运行SQL查询的代码是Glassfish上的Java容器。还有很多其他的查询可以运行，只是这一个给我带来了麻烦

如果有人能指出我的一个简单错误，那就太好了。或者，如果有人知道我如何更好地诊断这个问题，那将不胜感激

编辑，这是我的Java代码，因为请求组id是一个很长的过程

以下是完整的堆栈跟踪：

问号？在该声明的上下文中无效；MySQL不将其视为数字文本、字符串文本或有效引用

运行以下简单查询可能会导致相同的错误：

SELECT 'abc', 2, ?, NOW()

MySQL返回以下错误：

Error Code: 1064
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 '?, NOW()' at line 1

该问号字符可能是绑定变量的占位符。没有看到实际的代码，我们只是猜测。。。我们希望看到SQL文本作为参数传递给prepareStatement，然后在执行之前调用适当的方法将变量绑定到占位符，例如

  PreparedSatement ps = con.prepareStatement(sqltext);
  ps.setInt(1,groupId);
  ps.setInt(2,selected);
  ps.setInt(3,removed);

这个答案是在OP在问题中添加Java代码之前发布的。正如Joop Eggen的回答所指出的，在现在提供的OP代码中，这是一个简单的问题。。。executeQuery方法中提供的参数。对于准备好的语句，不要这样做。

尝试在=和？之间添加空格

String count = "SELECT COUNT(" + SUGGESTEDFOOD_ID + ") AS num_same, " 
     + SUGGESTEDFOOD_PLACEID + " FROM " + SUGGESTEDFOOD
     + " WHERE " + SUGGESTEDFOOD_GROUP_ID + "= ? AND "
     + SUGGESTEDFOOD_SELECTED + "= ? AND "
     + SUGGESTEDFOOD_REMOVED + "= ? "
     + "GROUP BY "
     + SUGGESTEDFOOD_PLACEID  + " LIMIT 1";

一个典型的错误

ResultSet rs = ps.executeQuery(count);

应该是

ResultSet rs = ps.executeQuery();

因为ps是一个PreparedStatement扩展语句，executeQueryString是一个不可用的语句方法

是否应该创建一个类似的API，重写executeQueryString并使用一个好的javadoc将其@Deprecated。

您在哪里设置了参数？您很可能执行了错误的查询，即您的Java代码有缺陷，因此如果您需要我们的帮助，您需要1显示代码，和2显示错误的完整stacktrace。执行代码时，问号不在那里，因为我使用的是准备好的语句，所以在打印未准备好的语句时，该代码正好位于调试语句中。

ResultSet rs = ps.executeQuery();
