capturing text

I have a large txt file where I want to return lines between a given condition eg
sample text...
create file 1
select * from mytable1
where id = 1
create file 2
select * from mytable3
where id = 1
create file 3
select * from
where id = 1

.. I would like a regular expression where if I want to search for "mytable3" and what "creat file" name it is contained within.
So, for "mytable3" the returned data should read...
create file2
create file3

Help much appreciated

Sorry - should have said I'm using Ruby. Will this still work?
ruby -e 'while line = STDIN.gets' -e 'c=line if line =~/create\s+file/' -e '$stdout.print(c,ARGV[0],"\n") if line.index(ARGV[0])' -e 'end' mytable3  < sampletext
