13.1.20.2 Files Created by CREATE TABLE
For an InnoDB table created in a
file-per-table tablespace or general tablespace, table data and
associated indexes are stored in an
ibd file in the database
directory. When an InnoDB table is created in
the system tablespace, table data and indexes are stored in the
ibdata* files that
represent the system tablespace. The
innodb_file_per_table option
controls whether tables are created in file-per-table
tablespaces or the system tablespace, by default. The
TABLESPACE option can be used to place a
table in a file-per-table tablespace, general tablespace, or the
system tablespace, regardless of the
innodb_file_per_table setting.
For MyISAM tables, the storage engine creates
data and index files. Thus, for each MyISAM
table tbl_name, there are two disk
files.
| File | Purpose |
|---|---|
|
Data file |
|
Index file |
Chapter 16, Alternative Storage Engines, describes what files each storage engine creates to represent tables. If a table name contains special characters, the names for the table files contain encoded versions of those characters as described in Section 9.2.3, “Mapping of Identifiers to File Names”.
