Question

I have a several postgres and mysql cursor objects exposed to me, created in some universe. How to find the database name (and other info about that db) from these cursor objects?

cursor.__dict__ gives nothing useful.

Answer 1

I don’t know about postgres but using MySQLdb you could always use the following:

cursor.execute("select database()")
db_name = cursor.fetchone()[0]

Maybe there’s a cleaner way to do this…

Edit:

for other info it depends on what exactly you’re looking for but for example to fetch table names

cursor.execute("show tables")
for r in cursor.fetchall():
    print r[0]

There are many other functions available… Is there anything specific you’re looking for?
