Ecco cosa uso per generare un dizionario di dati quando devo:
SELECT t.table_schema AS db_name,
t.table_name,
(CASE WHEN t.table_type = 'BASE TABLE' THEN 'table'
WHEN t.table_type = 'VIEW' THEN 'view'
ELSE t.table_type
END) AS table_type,
c.column_name,
c.column_type,
c.column_default,
c.column_key,
c.is_nullable,
c.extra,
c.column_comment
FROM information_schema.tables AS t
INNER JOIN information_schema.columns AS c
ON t.table_name = c.table_name
AND t.table_schema = c.table_schema
WHERE t.table_type IN ('base table', 'view')
AND t.table_schema LIKE '%'
ORDER BY t.table_schema,
t.table_name,
c.ordinal_position
Questo elencherà tutti i database sul server. Potresti voler modificare la clausola where per guardare solo lo schema di tabella specifico che desideri.
