    • Explain will give you more
      information about a query,
    • describe will give you more
      information about tables or columns.

    You can also use EXPLAIN on a table name, in which case it will behave exactly like DESCRIBE.

    EXPLAIN SELECT * 
FROM `customer`

id  select_type  table  type  possible_keys  key  key_len  ref  rows  Extra 
1 SIMPLE customer ALL NULL NULL NULL NULL 2

    vs.

    DESCRIBE `customer`
Field  Type  Null  Key  Default  Extra 
CustomerID varchar(2) NO      
Cx varchar(3) NO
