Hi everyone,
in my script I have to deal with a huge database with thousands of
tables. Given a table name (a python string) I would have to now if
such a table exists or not. Up to now I have written this function:
def DBGetTableByName(table_name) :
metadata = MetaData(engine)
try :
table = Table(table_name, metadata, autoload=True)
return table
except NoSuchTableError :
return None
I use its return value to check if the table exists, but the problem
is that it is too slow. Since I have to repeat this operation several
times I wonder if there is a faster (and smarter) way to perform this
control.
Any hints?
Thanks in advance!
