mysql_tableinfo − generate database metadata
|
mysql_tableinfo [options] db_name [db_like [tbl_like]] |
mysql_tableinfo creates tables and populates them with database metadata. It uses SHOW DATABASES, SHOW TABLES, SHOW TABLE STATUS, SHOW COLUMNS, and SHOW INDEX to obtain the metadata.
In MySQL 5.0 and up, the INFORMATION_SCHEMA database contains the same kind of information in the SCHEMATA, TABLES, COLUMNS, and STATISTICS tables. See Chapter 19, INFORMATION_SCHEMA Tables.
Invoke mysql_tableinfo like this:
shell> mysql_tableinfo [options] db_name [db_like [tbl_like]]
The db_name argument indicates which database mysql_tableinfo should use as the location for the metadata tables. The database will be created if it does not exist. The tables will be named db, tbl (or tbl_status), col, and idx.
If the db_like or tbl_like arguments are given, they are used as patterns and metadata is generated only for databases or tables that match the patterns. These arguments default to % if not given.
Examples:
mysql_tableinfo
info
mysql_tableinfo info world
mysql_tableinfo info mydb tmp%
Each of the commands stores information into tables in the info database. The first stores information for all databases and tables. The second stores information for all tables in the world database. The third stores information for tables in the mydb database that have names matching the pattern tmp%.
mysql_tableinfo supports the following options:
|
• |
−−help |
Display a help message and exit.
|
• |
−−clear |
Before populating each metadata table, drop it if it exists.
|
• |
−−clear−only |
Similar to −−clear, but exits after dropping the metadata tables to be populated.
|
• |
−−col |
Generate column metadata into the col table.
|
• |
−−host=host_name, −h host_name |
Connect to the MySQL server on the given host.
|
• |
−−idx |
Generate index metadata into the idx table.
|
• |
−−password=password, −ppassword |
The password to use when connecting to the server. Note that the password value is not optional for this option, unlike for other MySQL programs. You can use an option file to avoid giving the password on the command line.
Specifying a password on the command line should be considered insecure. See Section 5.6, “Keeping Passwords Secure”.
|
• |
−−port=port_num, −P port_num |
The TCP/IP port number to use for the connection.
|
• |
−−prefix=prefix_str |
Add prefix_str at the beginning of each metadata table name.
|
• |
−−quiet, −q |
Be silent except for errors.
|
• |
−−socket=path, −S path |
The Unix socket file to use for the connection.
|
• |
−−tbl−status |
Use SHOW TABLE STATUS instead of SHOW TABLES. This provides more complete information, but is slower.
|
• |
−−user=user_name, −u user_name |
The MySQL user name to use when connecting to the server.
