我在hive中创建了下表。
CREATE TABLE IF NOT EXISTS employee (
eid int,
name String,
salary String,
destination String
)
COMMENT ‘Employee details’
ROW FORMAT DELIMITED
FIELDS TERMINATED BY ‘\t’
LINES TERMINATED BY ‘\n’
STORED AS TEXTFILE;
表格已成功创建。我正在尝试执行以下插入
insert into TABLE employee (eid,name,salary,destination) VALUES (1,'avi','100000','boston');
但是,我收到以下错误消息。

我该如何解决这个问题?
答案 0 :(得分:2)
INSERT INTO employee select 1, 'avi', '100000', 'boston';
您的版本似乎不支持insert
列列表,也不支持values
。
P.S。
错误信息非常清楚
你应该专注于最后一行。
答案 1 :(得分:1)
请记住,在尝试插入字符串时需要使用引号。此外,当您为表中的所有字段插入值时,不需要字段名称。您可以尝试以下方法:
INSERT INTO TABLE employee
VALUES (1, 'avi', '100000', 'boston');
答案 2 :(得分:-1)
您不能像这样插入数据或插入命令,因为插入命令在SQL中使用。
要将数据加载到配置单元中,您必须创建一个文本文件,并且必须使用load命令上传该文件。
例如
LOAD DATA LOCAL INPATH 'YOUR TXT FILE LOCATION' OVERWRITE INTO TABLE TABLENAME;
