select some text
(select some text(select some text)
where some condition)
where condition;-->false;
select cl,c2,c3,c4,fn(),c5-->false;
select c1,c2,c3-->true;

for the first select it should be true.
for 2nd and 3rd statement its correct.

With this input file:

Code:
select some text
(select some text(select some text)
where some condition)
where condition;
select cl,c2,c3,c4,fn(),c5;
select c1,c2,c3;

and using this:
Code:
awk '{sub(/$/,RS)} /select/{s=/\(\)/?"false":"true";sub(/$/,"-->"s)}1' RS=\; infile

I get:

Code:
select some text
(select some text(select some text)
where some condition)
where condition;-->true
select cl,c2,c3,c4,fn(),c5;-->false
select c1,c2,c3;-->true
;

Is this not what you are getting?
Are you using Solaris?
