Two solutions using awk and gawk
With awk :
Code:
awk '
{ $0 = tolower($0) }
/^[[:space:]]*procedure/ {
   check_procedure();
   procedure = ""
}
{
   procedure = procedure " " $0;
}
END {
   check_procedure();
}
function check_procedure() {
   gsub(/\/\*[^*]*\*\//, "", procedure);
   gsub(/[[:space:]]+/, " ", procedure);
   if (procedure ~/insert into xyz/) {
      split(procedure, f);
      print "procedure",f[2];
   }
}
' inputfile

With gawk :
Code:
awk -v RS=procedure '
{
   gsub(/\n/, " ");
   gsub(/\/\*[^*]*\*\//, "");
   gsub(/[[:space:]]+/, " ")
   $0 = tolower($0);
}
/insert into xyz/ {
   print "procedure",$1
}
' inputfile

Inputfile:
Code:
procedure test1
insert into xyz;
end;
procedure
test2
insert
into
xyz
end;
procedure test3
insert /* asas*/
into xyz
end;
procedure test4
inserting into xyz
end;
procedure test5
insert into abcdef
end;

Output:
Code:
procedure test1
procedure test2
procedure test3

Thanks for wonderful response. This is working fine for me, however I forget to mention one this, i.e. it could be "procedure" or "function". I need to consider both, however above code only taking care of "procedure". Pls find the latest file and expected output.

Expected output:
procedure test1
function test2
procedure test3

File Contain:
procedure test1
insert into xyz;
end;

function

test2

insert

into
xyz
end;

procedure test3
insert /* asas*/
into xyz
end;

procedure test4
inserting into xyz
end;

Request you to update the command ASAP.

A new version of the awk solution :
Code:
awk '
{ $0 = tolower($0) }
/^[[:space:]]*(procedure|function)/ {
   check_procedure();
   procedure = ""
}
{
   procedure = procedure " " $0;
}
END {
   check_procedure();
}
function check_procedure() {
   gsub(/\/\*[^*]*\*\//, "", procedure);
   gsub(/[[:space:]]+/, " ", procedure);
   if (procedure ~/insert into xyz/) {
      split(procedure, f);
      print f[1],f[2];
   }
}
' inputfile

Inputfile:
Code:
procedure test1
insert into xyz;
end;
procedure
test2
insert
into
xyz
end;
procedure test3
insert /* asas*/
into xyz
end;
procedure test4
inserting into xyz
end;
procedure test5
insert into abcdef
end;
function ftest
insert into
xyz
end;

Output:
Code:
procedure test1
procedure test2
procedure test3
function ftest
