GBase 8a查看表的tableId

可以通过如下两种方案查看某表的tableID。

参考

GBase 8a查看和修改表的拥有者UID

GBase8a 集群查看建表结构,存储过程的语句

GBase 8a的show命令列表和使用

联机的tables表

查看information_schema.table表可以获得tableid。如下例子是9。

gbase> use information_schema;
Query OK, 0 rows affected (Elapsed: 00:00:00.00)

gbase> select * from tables where table_name='tmpab'\G
*************************** 1. row ***************************
              TABLE_CATALOG: NULL
               TABLE_SCHEMA: testdb
                 TABLE_NAME: tmpab
                 TABLE_TYPE: BASE TABLE
                     ENGINE: EXPRESS
                    VERSION: 10
                 ROW_FORMAT: Compressed
                 TABLE_ROWS: 0
             AVG_ROW_LENGTH: 0
                DATA_LENGTH: 0
            MAX_DATA_LENGTH: 0
               INDEX_LENGTH: 0
                  DATA_FREE: 0
             AUTO_INCREMENT: NULL
                CREATE_TIME: 2020-10-27 15:44:38
                UPDATE_TIME: 2020-10-27 15:49:21
                 CHECK_TIME: NULL
            TABLE_COLLATION: utf8_general_ci
                   CHECKSUM: NULL
             CREATE_OPTIONS: avg_row_length=307
   TABLE_LIMIT_STORAGE_SIZE: 0
         TABLE_STORAGE_SIZE: 770
            TABLE_DATA_SIZE: 0
              TABLE_COMMENT:
 LOCAL_HASH_INDEX_FILE_SIZE: 0
GLOBAL_HASH_INDEX_FILE_SIZE: 0
                        SCN: 26
                   TABLE_ID: 9
                  OWNER_UID: 1
1 row in set (Elapsed: 00:00:00.00)

离线通过metadump

通过metadump table.desc.A/B, 或者V95版本的table.info.A/B查看,其中的t_num就是tableid。如下例子同样的表是9。

[gbase@rh6-1 t1_n1.GED]$ metadump /opt/gcluster/userdata/gcluster/testdb/metadata/tmpab.GED/table.des.B
