Hi Sanja, I'm looking at I_S description for the DEFAULT partition and I see this: PARTITION_DESCRIPTION: (MAXVALUE,MAXVALUE) Is this normal? The full example below: show create table t10; +-------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Table | Create Table | +-------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | t10 | CREATE TABLE `t10` ( `i` varchar(10) DEFAULT NULL, `j` varchar(10) DEFAULT NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1 /*!50500 PARTITION BY LIST COLUMNS(i,j) (PARTITION p1 VALUES IN (('10','10')) ENGINE = InnoDB, PARTITION p2 DEFAULT ENGINE = InnoDB) */ | +-------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ 1 row in set (0.01 sec) MariaDB [j4]> select * from information_schema.partitions where table_name='t10'\G *************************** 1. row *************************** TABLE_CATALOG: def TABLE_SCHEMA: j4 TABLE_NAME: t10 PARTITION_NAME: p1 SUBPARTITION_NAME: NULL PARTITION_ORDINAL_POSITION: 1 SUBPARTITION_ORDINAL_POSITION: NULL PARTITION_METHOD: LIST COLUMNS SUBPARTITION_METHOD: NULL PARTITION_EXPRESSION: `i`,`j` SUBPARTITION_EXPRESSION: NULL PARTITION_DESCRIPTION: ('10','10') TABLE_ROWS: 0 AVG_ROW_LENGTH: 0 DATA_LENGTH: 16384 MAX_DATA_LENGTH: NULL INDEX_LENGTH: 0 DATA_FREE: 0 CREATE_TIME: 2016-09-08 21:22:45 UPDATE_TIME: NULL CHECK_TIME: NULL CHECKSUM: NULL PARTITION_COMMENT: NODEGROUP: default TABLESPACE_NAME: NULL *************************** 2. row *************************** TABLE_CATALOG: def TABLE_SCHEMA: j4 TABLE_NAME: t10 PARTITION_NAME: p2 SUBPARTITION_NAME: NULL PARTITION_ORDINAL_POSITION: 2 SUBPARTITION_ORDINAL_POSITION: NULL PARTITION_METHOD: LIST COLUMNS SUBPARTITION_METHOD: NULL PARTITION_EXPRESSION: `i`,`j` SUBPARTITION_EXPRESSION: NULL PARTITION_DESCRIPTION: (MAXVALUE,MAXVALUE) TABLE_ROWS: 0 AVG_ROW_LENGTH: 0 DATA_LENGTH: 16384 MAX_DATA_LENGTH: NULL INDEX_LENGTH: 0 DATA_FREE: 0 CREATE_TIME: 2016-09-08 21:22:45 UPDATE_TIME: NULL CHECK_TIME: NULL CHECKSUM: NULL PARTITION_COMMENT: NODEGROUP: default TABLESPACE_NAME: NULL 2 rows in set (0.01 sec) BR Sergei -- Sergei Petrunia, Software Developer MariaDB Corporation | Skype: sergefp | Blog: http://s.petrunia.net/blog
