Question perl pattern matching
hi i am trying to get digits inside brackes from file , whose structure is defined below

Code:
CREATE TABLE TELM
(SOC_NO                 CHAR (3)     NOT NULL,
 TXN_AMOUNT          NUMBER (17,3)  
 SIGN_ON_TIME        CHAR (8)     
 TELLER_APP_LIMIT   NUMBER (17,3)  
 FIL01                     CHAR (11)    
CONSTRAINT TELMPK
PRIMARY KEY (SOC_NO,
             TELLER_NO),
CONSTRAINT TELMUK_02
UNIQUE      (SOC_NO,
             TELLER_NO,
             SUP_TELLER));

i want only digits inside bracket i am able to get digits from bracket (which is BOLD) if there is only one digit eg :
Code:
[(SOC_NO                 CHAR (3)     NOT NULL,]

with following code

Code:
 if (/^.*(CHAR|NUMBER)\s*.*$/) {
             $_ =~ s/ DEFAULT(.*)// ;
             print "$_\n" ;
         if (/^.*\((\d+)\).*$/) {
             print "one:$1\n" ;
          }elsif (/^.*\((\d\d),(\d)\).*$/) {
             print "two :$2\n" ;
          }

but i am not able to get digits if they are specified with comma in between like :
Code:
TXN_AMOUNT          NUMBER (17,3)

for above i want 17 in 1 varaible and 3 in other but i m not able to manage it i get only digit specified after "," 3 for above case.

LEARN ABOUT SUSE

create_tablespace

CREATE 
TABLESPACE(7)						   SQL Commands 					      CREATE TABLESPACE(7)

NAME

       CREATE TABLESPACE - define a new tablespace

SYNOPSIS

       CREATE TABLESPACE tablespacename [ OWNER username ] LOCATION 'directory'

DESCRIPTION

       CREATE TABLESPACE registers a new cluster-wide tablespace. The tablespace name must be distinct from the name of any existing tablespace in
       the database cluster.

       A tablespace allows superusers to define an alternative location on the file system where the data files containing database objects  (such
       as tables and indexes) can reside.

       A  user	with  appropriate  privileges can pass tablespacename to CREATE DATABASE, CREATE TABLE, CREATE INDEX or ADD CONSTRAINT to have the
       data files for these objects stored within the specified tablespace.

PARAMETERS

       tablespacename
	      The name of a tablespace to be created. The name cannot begin with pg_, as such names are reserved for system tablespaces.

       username
	      The name of the user who will own the tablespace. If omitted, defaults to the user executing the command. Only superusers can create
	      tablespaces, but they can assign ownership of tablespaces to non-superusers.

       directory
	      The directory that will be used for the tablespace. The directory must be empty and must be owned by the PostgreSQL system user. The
	      directory must be specified by an absolute path name.

NOTES

       Tablespaces are only supported on systems that support symbolic links.

       CREATE TABLESPACE cannot be executed inside a transaction block.

EXAMPLES

       Create a tablespace dbspace at /data/dbs:

       CREATE TABLESPACE dbspace LOCATION '/data/dbs';

       Create a tablespace indexspace at /data/indexes owned by user genevieve:

       CREATE TABLESPACE indexspace OWNER genevieve LOCATION '/data/indexes';

COMPATIBILITY

       CREATE TABLESPACE is a PostgreSQL extension.
