MySQL with JDBC: select * 来自 mysql.proc => FUNCTION * 不存在

MySQL with JDBC: select * from mysql.proc => FUNCTION * does not exist

MySQL 与 JDBC:

select * from mysql.proc
________________________
    PreparedStatement selectClientIDsStatement = null;
    Connection connection = Db.getConnection();
    try {
        String query = "select * from mysql.proc";
        selectClientIDsStatement = connection.prepareCall(query);
        ...exception
    } catch (SQLException e) {
        throw new VeException(e);
    } finally {...
    }

=> 函数 * 不存在 但是 Workbench 给出了正常结果。为什么会这样?

似乎是一条奇怪的错误消息 - 我刚刚用 mysql-connector-java-5.1.34(针对 5.5.42 MySQL 社区服务器)尝试了这个并且它有效(没有例外,但也没有返回行)...

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class MySQL {

    public static void main(String[] args) throws Exception {
        Class.forName("com.mysql.jdbc.Driver").newInstance();

        Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/test?user=root&password=root");

        Statement statement = conn.createStatement();
        ResultSet resultSet = statement.executeQuery("select * from mysql.proc");

        while (resultSet.next()) {
            System.out.println("GOT A ROW!");
        }

        resultSet.close();
        statement.close();
        conn.close();
    }
}

您的查询字符串是否包含硬空格或其他内容?

更新

您似乎在使用 prepareCall 而不是 prepareStatement
