创建表格查询的MismatchedTokenException

Question

我正在尝试使用以下查询创建一个Hive表：

CREATE TABLE IF NOT EXISTS BXDataSet 
    (ISBN STRING, 
    BookTitle STRING, 
    BookAuthor STRING, 
    YearOfPublication STRING, 
    Publisher STRING, 
    ImageURLS STRING, 
    ImageURLM STRING, 
    ImageURLL STRING) 
COMMENT 'BX-Books Table' 
ROW FORMAT DELIMITED FIELDS TERMINATED BY ';' LINE TERMINATED BY '\n'
STORED AS TEXTFILE;

当我向Hive提交时，我是如何得到以下例外的：

正确安装了蜂箱，我可以运行像显示表这样的东西。那么，这个查询有什么问题呢？

Answer 1

您需要指定分隔符的OCT代码。

为；OCT代码为073。

  CREATE TABLE IF NOT EXISTS BXDataSet 
(ISBN STRING, 
BookTitle STRING, 
BookAuthor STRING, 
YearOfPublication STRING, 
Publisher STRING, 
ImageURLS STRING, 
ImageURLM STRING, 
ImageURLL STRING) 
COMMENT 'BX-Books Table' 
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\073' LINE TERMINATED BY '\n'
 STORED AS TEXTFILE;

Answer 2

WRONGLINE TERMINATED BY '\n'

RIGHTLINES TERMINATED BY '\n'

“LINE”不是“行”

Answer 3

简单的答案是转义";“，这样行将是行格式分隔字段，以‘\’行结束，以'\n‘结尾。
