9.15 Determining the Current Database
9.15.1 Problem
Has any database been selected as
the current database? What is its name?
9.15.2 Solution
Use the DATABASE( ) function.
9.15.3 Discussion
SELECT DATABASE( ) returns the
name of the current database, or the empty string if no database has
been selected. This Python code uses the statement to present a
status display containing information about the current connection:
cursor = conn.cursor ( )
cursor.execute ("SELECT DATABASE( )")
row = cursor.fetchone ( )
cursor.close
if row == None or len (row) == 0 or row[0] == "":
db = "(no database selected)"
else:
db = row[0]
print "Current database:", db
