MySQL 5.7 Reference Manual  /  ...  /  The INFORMATION_SCHEMA INNODB_SYS_DATAFILES Table

23.31.17 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 15.15.3, “InnoDB INFORMATION_SCHEMA System Tables”.

Table 23.17 INNODB_SYS_DATAFILES Columns

Column nameDescription
SPACEThe tablespace Space ID.
PATHThe tablespace data file path (for example, .\world\innodb\city.ibd). If a file-per-table tablespace is created in a location outside the MySQL data directory using the DATA DIRECTORY clause of the CREATE TABLE statement, the tablespace PATH field shows the fully qualified directory path.

Example:

mysql> SELECT * FROM INFORMATION_SCHEMA.INNODB_SYS_DATAFILES WHERE SPACE = 57\G
*************************** 1. row ***************************
SPACE: 57
 PATH: ./test/t1.ibd
