Help required to parse Oracle imp show=y output to DDL Commands

rajan_san · #1 08-26-2008

Hi,

I generated an Oracle schema DDL script file using the show=y option of the Oracle import utility but the file that it generates needs a little more formating before we can run this as simple DDL comands to generate the schema at Target using the script file.Here is the simplified output of the file generated for one of the tables which i am trying to parse to a set of CREATE TABLE and ALTER TABLE commands

Output Generated
------------------

Requirements
------------

We need to remove the " from each line enclosing the line as in the output file
Introduce 2 new lines between start and end of each command and provide a / to be able to run as a command in sql

Every Create Table command start with "CREATE TABLE.. and ends with LOGGING NOCOMPRESS"

Every ALTER TABLE Command starts with " ALTER TABLE... and ends with )"

Every New Create Table starts After . . skipping table line

Basically my outfile has a collection of these commands so i need a script that can run in a loop and parse all these statements and put in an outfile

Quick response is appreciated...

Thanks and Kind Regards,
Rajan.S

As a starting point :

Code:

awk '
/^".*"$/ {
   $0 = substr($0, 2, length-2);
}

/^ *CREATE TABLE/ {
   sql = $0;
   while ($0 !~ /LOGGING NOCOMPRESS$/) {
      if (! getline) break;
      $0 = substr($0, 2, length-2);
      sql = sql "\n" $0;
   }
   print sql "\n/";
   next;
}

/^ *ALTER TABLE/ {
   sql = $0;
   while (substr($0,length,1) != ")") {
      if (! getline) break;
      $0 = substr($0, 2, length-2);
      sql = sql "\n" $0;
   }
   print sql "\n/";
   next;
}
