Question

我尝试使用以下查询创建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;

当我提交给Hive时，我得到以下异常：

MismatchedTokenException(-1!=301)

Hive已正确安装，我可以运行show table之类的东西。那么，这个查询的问题是什么？

Answer 1

您需要指定分隔符的OCT代码。

那是为了; OCT代码是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

<强> WRONG LINE TERMINATED BY '\n'

从右 LINES TERMINATED BY '\n'

＆＃39; LINES＆＃39;不是＆＃39; LINE＆＃39;

Answer 3

简单的答案是逃避“;”像这样 ”\;” 所以你的路线就是由'\;'终止的行格式删除字段由'\ n'

终止的行

Answer 4

CREATE TABLE IF NOT NOT EXISTS BXDataSetNew （ISBN STRING， BookTitle STRING， BookAuthor STRING， YearOfPublication STRING，发布者STRING， ImageURLS STRING， ImageURLM STRING， ImageURLL STRING）评论＆＃39; BX-书籍表＆＃39; ROW FORMAT DELIMITED FIELDS终止于＆＃39; \ t＆＃39;线路终止于＆＃39; \ n＆＃39; 存储为文本文件;
