regex - How to print tablename and primary key from file.sql in python -

-

i have requirement print tablename , primary key using below program. not working. please in solving this. have used regex pattern find out table name , primary key data in database schema.

class parsecreatefile:      begin = re.compile(r"create \s+ table \s+'((?:[^']|'')*)'.+(primary \s+ key\s? \([^)]*\))", re.ignorecase | re.verbose | re.dotall)      def __init__(self,filename):         self.filename = filename         self.readfromfile()      def readfromfile(self):         try:             file = open(self.filename,'r')             filedata = file.read()             file.close()             self.parse(filedata)         except ioerror:             print 'unable read file %s' % self.filename      def parse(self,rawdata):         self.list = []         while rawdata:           mo = self.begin.search(rawdata)           tablename, fil = mo.groups()           print tablename, fil           if mo none:             break           rawdata = rawdata[mo.end():]      if __name__ == '__main__':         print "only main classes"         file = parsecreatefile('file2.sql')

file2.sql

create table 'x'(   'x' integer   primary key(dn)   'y' short); create table 'y'(   'x1' integer   primary key(dn1, dn2)   'y1' short);  expected out: x: primary key(dn) y: primary key(dn1, dn2)

i edited regex, , used findall.

class parsecreatefile:      begin = re.compile(r"create table[ ']*([^ ']+)[ ']*[(][^/;]+(primary key.*)[^/;]+;", re.ignorecase)      def __init__(self,filename):         self.filename = filename         self.readfromfile()      def readfromfile(self):         try:             file = open(self.filename,'r')             filedata = file.read()             file.close()             self.parse(filedata)         except ioerror:             print 'unable read file %s' % self.filename      def parse(self,rawdata):         self.list = []         found = self.begin.findall(rawdata)         in found:             print i[0], i[1]   if __name__ == '__main__':     print "only main classes"     file = parsecreatefile('file2.sql')
