Question

SQL查询在MySQL数据库中运行良好，但是当我在JDBC中使用相同的查询时，我得到：

您的SQL语法有错误;查看与您的MySQL服务器版本对应的手册，以便在第1行'Foods Ltd AND clsp_stockexchange = bse GROUP BY CLSP_DATEOFTRADE'附近使用正确的语法

MySQL版本是5.0。我的jdbc代码：

Class.forName(driver).newInstance();
conn = DriverManager.getConnection(url+dbName,userName,password);
String query = "SELECT  max(CLSP_DATEOFTRADE) AS TradeDate,CLSP_CLOSEPRICE FROM     stock.clccompany1 LEFT JOIN stock.clsp1 ON clccompany1.clcm_clsm_keyid=clsp1.clsp_clcm_keyid WHERE clcm_nameofthecompany=ADF Foods Ltd AND clsp_stockexchange=bse GROUP BY CLSP_DATEOFTRADE";
Statement st = conn.createStatement();
ResultSet  rs = st.executeQuery(query);
while(rs.next())
{
    String s1=rs.getString(1);
    String s2=rs.getString(2);
    out.print(s1);
    out.print(s2);
}

Answer 1

我在where子句

的问题

WHERE clcm_nameofthecompany = ADF Foods Ltd 
  AND clsp_stockexchange=bse 
GROUP BY CLSP_DATEOFTRADE

需要用报价包装ADF Foods Ltd。如

WHERE clcm_nameofthecompany = 'ADF Foods Ltd' 
     AND clsp_stockexchange=bse 
GROUP BY CLSP_DATEOFTRADE

“你的SQL语法有错误”
