Description
Enhancement
TiDB supports the 'local temporary table'(compatible with MySQL) and 'global temporary table'(from ANSI SQL standard). However, there is no temporary table information in information_schema.tables, it's not very easy to manage them.
So we would like to add both local temporary and global temporary tables in information_schema.tables. For TABLE_TYPE column, we show LOCAL TEMPORARY for a local temporary table, GLOBAL TEMPORARY for a global temporary table
Note: this is not compatible with MySQL.
- MySQL only supports local temporary table, and they do not show local temporary table in information_schema.tables. Instead, it provides
information_schema.INNODB_TEMP_TABLE_INFO. - We think it is fine because we follow the SQL standard.
