Convert Ascii value to Character in hive
问题 I want to convert ascii value to its character in hive.Is there any existing function in a hive (like we have char function in SQL server).Does anyone knows how to achieve this in a hive? For Example: For 65 , result would be A. Thanks in advance. 回答1: This is possible by combining a few of the built in functions: Select decode(unhex(hex(65)), 'US-ASCII'); hex changes the int value to a Hexadecimal string, while unhex changes this to binary. then decode interprets the binary as ASCII data. 来源
