24.4.18 The INFORMATION_SCHEMA INNODB_SYS_DATAFILES Table

The INNODB_SYS_DATAFILES table provides data file path information for InnoDB file-per-table and general tablespaces, equivalent to the information in the SYS_DATAFILES table in the InnoDB data dictionary.

For related usage information and examples, see Section 14.16.3, “InnoDB INFORMATION_SCHEMA System Tables”.

Note

The INFORMATION_SCHEMA FILES table reports metadata for all InnoDB tablespace types including file-per-table tablespaces, general tablespaces, the system tablespace, the temporary tablespace, and undo tablespaces, if present.

The INNODB_SYS_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_SYS_DATAFILES WHERE SPACE = 57\G
*************************** 1. row ***************************
SPACE: 57
 PATH: ./test/t1.ibd
