我正在尝试使用Spring中的jdbc模板更新查询更新mysql DB

我的查询 

String query = "update request set regions=?, requesttype=?, requestorigin=?, lineofbusiness=?, destinationenvironment=?, release=?, workrequest=?,"
                    + " spmid=?, requestingteam=? where requestid="+request.getRequestId()+";"; 
            System.out.println(query);
            Object[] params = {request.getRegions(), request.getRequestType(), request.getRequestOrigin(),
                    request.getLineOfBusiness(),
                    request.getDestinationEnvironment(),
                    request.getReleaseValue(), request.getWorkRequest(),
                    request.getSpmId(), request.getRequestingTeam()
                     };
            int[] types = { Types.VARCHAR, Types.VARCHAR, Types.VARCHAR, Types.VARCHAR,
                    Types.VARCHAR, Types.VARCHAR, Types.VARCHAR, Types.VARCHAR,
                    Types.VARCHAR };
            return jdbcTemplate.update(query, params, types);

当我运行此查询时，它显示Mysql Grammar错误。我无法找到 哪里出错了。

答案 0 :(得分：2)

基于此错误消息：

  

com.mysql.jdbc.exceptions.MySQLSyntaxErrorException：SQL语法中有错误;查看与您的MySQL服务器版本相对应的手册，以便在＆＃39; release =＆＃39; Search and Load＆＃39;，workrequest =＆＃39; zxZ＆＃39;，spmid =＆＃39;附近使用正确的语法; zxXZxZ＆＃39;，requesteam =＆＃39; Se＆＃39;在第1行

问题似乎与release列有关。 你确定这个专栏存在吗？ （正确拼写，在名称中更正大小写。）

<强>更新

事实证明，release是MySQL中的关键字。 你需要使用反引号引用该字段，如下所示：

String query = "update request set regions=?, `release`=?, workrequest=?,"

与您的问题无关， 但就像你注入值设置？参数，对条件中的request.getRequestId()执行相同操作，而不是字符串连接。这样它将以类型安全的方式注入。

也就是说，SQL字符串的结尾应该如下所示：

... where requestid= ?

并在参数中添加request.getRequestId()，就像您在params和types中设置的其他值一样。

答案 1 :(得分：2)

检查是否通过引号，是否解决了问题？

"update `request` set `regions`=?, `requesttype`=?, `requestorigin`=?, `lineofbusiness`=?, `destinationenvironment`=?, `release`=?, `workrequest`=?,"
                    + " `spmid`=?, `requestingteam`=? where `requestid`="

答案 2 :(得分：0)

为什么不在查询中参数化requestId？假设requestId的类型为INTEGER，则可以将代码重写为：

String query = "update request set regions=?, requesttype=?, requestorigin=?, lineofbusiness=?, destinationenvironment=?, release=?, workrequest=?,"
                    + " spmid=?, requestingteam=? where requestid=?"; 
System.out.println(query);
Object[] params = {request.getRegions(), request.getRequestType(), request.getRequestOrigin(),
        request.getLineOfBusiness(),
        request.getDestinationEnvironment(),
        request.getReleaseValue(), request.getWorkRequest(),
        request.getSpmId(), request.getRequestingTeam(),
         request.getRequestId()};
int[] types = { Types.VARCHAR, Types.VARCHAR, Types.VARCHAR, Types.VARCHAR,
        Types.VARCHAR, Types.VARCHAR, Types.VARCHAR, Types.VARCHAR,
        Types.VARCHAR, Types.INTEGER };
return jdbcTemplate.update(query, params, types);

请告诉我这是否适合您。

答案 3 :(得分：0)

request.getSpmId(), request.getRequestingTeam(),

您在Object数组的末尾放置一个逗号。
