Struct doesn't have its own section in the Types doc <https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Types>, but it could (see Complex Types <https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Types#LanguageManualTypes-ComplexTypes>). However I don't think people will look there for information about case sensitivity -- it belongs in the DDL and DML docs. Case-insensitivity for column names is mentioned here:
- Create Table <https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-CreateTable> (notes immediately after the syntax) - Alter Column -- Rules for Column Names <https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-AlterColumn> - Select Syntax <https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Select#LanguageManualSelect-SelectSyntax> (notes after the syntax) The ORC doc could also mention this issue, preferably in the section Hive QL Syntax <https://cwiki.apache.org/confluence/display/Hive/LanguageManual+ORC#LanguageManualORC-HiveQLSyntax> . -- Lefty On Wed, Jul 9, 2014 at 11:48 PM, Navis류승우 <navis....@nexr.com> wrote: > For column name, hive restricts it as a lower case string.
