Hello, I was looking at whether column names used by EIS feature are consistent with themselves and with ther parts of the server. == Database / table / column names == There are a few naming conventions arready in use: 1. Old school: mysql.columns_priv, tables_priv Db Table_name Column_name 2. SQL STANDARD ALL CAPS HELLO FROM 1970S: information_schema.* (tables, columns, indexes, index_statistics, etc) TABLE_CATALOG (always 'def') TABLE_SCHEMA TABLE_NAME COLUMN_NAME INDEX_NAME 3. InnoDB has its own convention: mysql.innodb_table_stats, innodb_index_stats database_name table_name index_name 4. EITS feature will add: mysql.column_stats, index_stats, table_stats db_name table_name column_name index_name == Other == There are variables @@histogram_size, @@histogram_type. mysql.column_stats has columns named hist_size, hist_type. What's your opinion, should we make some renames to make things more consistent? BR Sergei -- Sergei Petrunia, Software Developer MariaDB | Skype: sergefp | Blog: http://s.petrunia.net/blog
