The INNODB_DATAFILES
table provides
data file path information for InnoDB
file-per-table and general tablespaces.
For related usage information and examples, see Section 15.14.3, “InnoDB INFORMATION_SCHEMA Schema Object Tables”.
The INFORMATION_SCHEMA
FILES
table reports metadata for
InnoDB
tablespace types including
file-per-table tablespaces, general tablespaces, the system
tablespace, the global temporary tablespace, and undo
tablespaces.
The INNODB_DATAFILES
table has these
columns:
SPACE
The tablespace ID.
PATH
The tablespace data file path. If a file-per-table tablespace is created in a location outside the MySQL data directory, the path value is a fully qualified directory path. Otherwise, the path is relative to the data directory.
Example
mysql> SELECT * FROM INFORMATION_SCHEMA.INNODB_DATAFILES WHERE SPACE = 57\G
*************************** 1. row ***************************
SPACE: 57
PATH: ./test/t1.ibd
