SHOW VARIABLES
--------------
`SHOW VARIABLES\' shows the values of the some of *MySQL* system
variables. You can also get this information using the `mysqladmin
variables\' command. If the default values are unsuitable, you can set
most of these variables using command-line options when `mysqld\' starts
up. *Note Command-line options::.
The output resembles that shown below, though the format and numbers may
differ somewhat:
+----------------------------+------------------------------+
| Variable_name | Value |
+----------------------------+------------------------------+

| max_heap_table_size | 16777216 |
