second88 updated DRILL-5843:
----------------------------
Component/s: Storage - Information Schema
> Incorrect values of INFORMATION_SCHEMA.TABLES.TABLE_TYPE
> --------------------------------------------------------
>
> Key: DRILL-5843
> URL: https://issues.apache.org/jira/browse/DRILL-5843
> Project: Apache Drill
> Issue Type: Bug
> Components: Metadata, Storage - Information Schema
> Affects Versions: 1.10.0
> Reporter: second88
> Priority: Minor
>
> As far as I can see, the values available in Drill include:
> TABLE
> VIEW
> SYSTEM_TABLE
> In a draft of SQL standard SQL:2011 Part 11: Information and Definition
> Schemas (SQL/Schemata), the available values should be (source: [SQL:201x
> (preliminary)|https://wiki.postgresql.org/wiki/Developer_FAQ#Where_can_I_get_a_copy_of_the_SQL_standards.3F]):
> BASE TABLE
> VIEW
> GLOBAL TEMPORARY
> LOCAL TEMPORARY
> SYSTEM VERSIONED
> Some common databases, which have implemented INFORMATION_SCHEMA.TABLES view,
> show "BASE TABLE" instead of "TABLE" and use " " instead of "_" as delimiter
> in the values of TABLE_TYPE:
> [MySQL 5.7|https://dev.mysql.com/doc/refman/5.7/en/tables-table.html]
> [PostgreSQL
> 9.1|https://www.postgresql.org/docs/9.1/static/infoschema-tables.html]
> [DB2 for
> i5/OS|https://www.ibm.com/support/knowledgecenter/ssw_i5_54/db2/rbafzmstcatalogans.htm#cattables]
> In conclusion, "TABLE" should be replaced by "BASE TABLE" and "SYSTEM_TABLE"
> by "SYSTEM TABLE" in INFORMATION_SCHEMA.TABLES.TABLE_TYPE.
> Besides, the words in other existing or future values of TABLE_TYPE should
> also be delimited by " " instead of "_", for example, "GLOBAL TEMPORARY"
> instead of "GLOBAL_TEMPORARY".
