Question

我无法创建hive表。以下是代码

CREATE TABLE NYSE(exchange STRING, stock_symbol STRING, stock_date DATE,
stock_price_open FLOAT, stock_price_high FLOAT, stock_price_low FLOAT,     
stock_price_close FLOAT, stock_volume INT, stock_price_avg_close FLOAT)
ROW FORMAT DELIMITED FIELDS TERMINATED BY ',';

这会返回以下错误消息：

我正在使用Hive 2.1.0和Hadoop 2.7.3

请帮帮我。

Answer 1

您不能在列名定义中使用“exchange”Reserved keywords。

尝试给出像exchange_1或使用`转到你的第一个列名。

尝试以下步骤：

USE your_DB_Name;

DROP TABLE IF EXISTS NYSE PURGE;

CREATE TABLE NYSE (`exchange` STRING, stock_symbol STRING, stock_date DATE, stock_price_open FLOAT, stock_price_high FLOAT, stock_price_low FLOAT, stock_price_close FLOAT, stock_volume INT, stock_price_avg_close FLOAT) ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' ;

Answer 2

Exchange是HIVE中的保留关键字

您可以使用反引号（``）符号

来转义它

这应该有效：

CREATE TABLE NYSE(
`exchange` STRING
,stock_symbol STRING
,stock_date DATE
,stock_price_open FLOAT
,stock_price_high FLOAT
,stock_price_low FLOAT
,stock_price_close FLOAT
,stock_volume INT
,stock_price_avg_close FLOAT)
ROW FORMAT DELIMITED FIELDS TERMINATED BY ',';

Answer 3

exchange是hive中的关键字，因此您无法使用。而不是使用交换或其他任何东西。试试这个..

create table nyse（exchangee String，stock_symbol String，stock_date String，stock_price_open double，stock_price_high double，stock_price_low double，stock_price_close double，stock_volume double，stock_price_adj_close double）行格式分隔的字段以“，”结束;
