Extract specific lines from a file
Hi,
I have a file which contains DDL statements- CREATE TABLE, CREATE INDEX, ALTER TABLE etc.
I have to only pick CREATE TABLE statements from the file-
Source :
----------------------------------------------
--DDL for table abc
--------------------------------------------
CREATE TABLE abc(
col1 integer,
col2 varchar2(20),
col3 varchar2(50)
);
CREATE INDEX <statements>
<statements>
Output file should have only the lines for CREATE TABLE:
CREATE TABLE abc(
col1 integer,
col2 varchar2(20),
col3 varchar2(50)
);
So I have to process through the file and only pick the CREATE TABLE statements (multiple instances) and output to an output file.
Could you please help me writing a shell script for the same?

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.
