我用ORC创建了一个hive表。如果我从蜂巢控制台插入数据它完美地工作。但是如果我从Jdbc代码中插入数据。它会抛出hive语义异常。
错误

我的插入查询
result = name+","+age+","+job;
String stmt = "INSERT INTO table real_estate.addressinformation_orc VALUES(" + result + ")";
任何帮助将不胜感激。

你需要引用字符串。假设年龄是一个整数,这将有效,但这是一个糟糕的解决方案:
result = "'" + name + "'," + age + ",'" + job + "'"
这是一个基本的解决方案,因为如果名称和工作计算引用,那将破坏您的代码。 更好的解决方案是使用预准备语句。准备好的陈述,您不必担心qoting:
preparedStatement = dbConnection.
prepareStatement("INSERT INTO table " +
"real_estate.addressinformation_orc VALUES(?,?,?)");
preparedStatement.setString(1, name);
preparedStatement.setInt(2, age);
preparedStatement.setString(3, job);
// execute insert SQL stetement
preparedStatement.executeUpdate();
答案 1 :(得分:0)
您需要在字符串引号中添加结果变量。
例如: 插入表test1(sno,name)值(1,jj);
上面的行抛出错误,如果我们编辑相同的下面就行了
插入表test1(sno,name)值(1," jj");
这里name数据类型是字符串
