Extracting few lines from a file based on identifiers dynamically
i have something like this in a file called mysqldump.sql

Code:

--
-- Table structure for table `Table11`
--
DROP TABLE IF EXISTS `Table11`;
/*!40101 SET @saved_cs_client = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `Table11` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`entityName` enum('Lines','EndUsers') COLLATE utf8_unicode_ci NOT NULL,
`parentAllianceMigrationProjectId` int(11) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2000 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
/*!40101 SET character_set_client = @saved_cs_client */;
--
-- Table structure for table `Table22`
--
DROP TABLE IF EXISTS `Table22`;
/*!40101 SET @saved_cs_client = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `Table22` (
`empNo` int(13) NOT NULL AUTO_INCREMENT,
`channels` enum('one','two','three') COLLATE utf8_unicode_ci NOT NULL,
) ENGINE=InnoDB AUTO_INCREMENT=2000 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
/*!40101 SET character_set_client = @saved_cs_client */;
--
-- Table structure for table `Table33`
--
DROP TABLE IF EXISTS `Table33`;
/*!40101 SET @saved_cs_client = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `Table33` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`allianceId` int(11) NOT NULL,
`migratedAt` datetime DEFAULT NULL,
`migrationDetail` text COLLATE utf8_unicode_ci,
`unigyId` int(11) DEFAULT NULL,
) ENGINE=InnoDB AUTO_INCREMENT=2000 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
/*!40101 SET character_set_client = @saved_cs_client */;

what i need is to extract only the create table part of each table and store it in a file, say i need to extract only
Code:
CREATE TABLE `Table11` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`entityName` enum('Lines','EndUsers') COLLATE utf8_unicode_ci NOT NULL,
`parentAllianceMigrationProjectId` int(11) NOT NULL,
PRIMARY KEY (`id`)
)

the above part and store it in a file. i need this to be dynamic, i mean i will be using the script in a while loop so in first iteration of while loop i need table11 to be stored in a tmp.sql file and in next iteration the while loop automatically stores table22 in the tmp.sql file. since we need idetifiers to clip we could use "CREATE TABLE" as starting point and "ENGINE=InnoDB" as end point for clipping. this is very easy in java programming i dont know how to do this in shell scripting. any help is deeply appreciated

thanks,
vivek

LEARN ABOUT LINUX

drop_table

DROP 
TABLE(7)							   SQL Commands 						     DROP TABLE(7)

NAME

       DROP TABLE - remove a table

SYNOPSIS

       DROP TABLE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP  TABLE  removes tables from the database.  Only its owner can drop a table. To empty a table of rows without destroying the table, use
       DELETE [delete(7)] or TRUNCATE [truncate(7)].

       DROP TABLE always removes any indexes, rules, triggers, and constraints that exist for the target table.  However, to drop a table that	is
       referenced  by  a  view	or  a  foreign-key  constraint	of another table, CASCADE must be specified. (CASCADE will remove a dependent view
       entirely, but in the foreign-key case it will only remove the foreign-key constraint, not the other table entirely.)

PARAMETERS

       IF EXISTS
	      Do not throw an error if the table does not exist. A notice is issued in this case.

       name   The name (optionally schema-qualified) of the table to drop.

       CASCADE
	      Automatically drop objects that depend on the table (such as views).

       RESTRICT
	      Refuse to drop the table if any objects depend on it. This is the default.

EXAMPLES

       To destroy two tables, films and distributors:

       DROP TABLE films, distributors;

COMPATIBILITY

       This command conforms to the SQL standard, except that the standard only allows one table to be dropped per command, and apart from the	IF
       EXISTS option, which is a PostgreSQL extension.
