7 replies Hi, I believe my Hive version is Apache 1.2.0. I guessed it from the folder and hive-hwi.jar names. I am trying to insert values into a column of type timestamp. It does not work This is how I create the table CREATE TABLE tmp reporttime timest I tried following insert queries INSERT INTO TABLE tmp VALUES734196.3552; INSERT. I couldn't think of any built in function in hive to handle this scenario. The other way of doing this is by using something like below: select from_unixtimeunix_timestampcurrent_timestamp7200; 7200 implies seconds needed for 2 hours as mentioned in your quetion. You can alter it based on your need. CREATE EXTERNAL TABLE `uncleaned` `a` int, `b` string, `c` string, `d` string, `e` bigint ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' STORED AS INPUTFORMAT 'org.apache.hadoop.mapred.TextInputFormat' OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat' LOCATION '/external/uncleaned'. 1 reply Hi, I have a column called dateofbirth in my hive table and the date of birth is stored as a BigInt Unix_timestamp. Now I want to query this table using this query SELECT FROM mytable WHERE dataofbirth=unix_timestamp'2011-10-08'; However, this query is returning 0 results but I know there are 11 entries whose date of birth is. HIVE Date Functions from_unixtime: This function converts the number of seconds from unix epoch 1970-01-01 00:00:00 UTC to a STRING that represents the TIMESTAMP of that moment in the current system time zone in the format of “1970-01-01 00:00:00”. The following example returns the current date including the time.

This file is somehow loaded into Hive e.g. load data inpath 'file.csv' into table output_table And the question is what format to use when writing to file? If this is correct, if you have defined this column as timestamp, then the output should be one of the supported formats of timestamp for Hive.
Many applications manipulate the date and time values. Latest Hadoop Hive query language support most of relational database date functions. In this article, we will check commonly used Hadoop Hive date functions and some of examples on usage of those functions. Hadoop Hive Date Functions Date types are highly formatted and very complicated. 可怕,hive版本1.2.1,实践中发现,to_unix_timestamp比unix_timestamp函数快几十甚至上百倍! 博文 来自: Sin_Geek成长の迹 Hive中TimeStamp精度问题分析.
