8.24. mysql_tableinfo — Generate Database Metadata

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 20, The INFORMATION_SCHEMA Database.

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.


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:
