Code:
#perl -lne '(/^\s*CREATE\s+TABLE/i .. /^\s*\)\s+ENGINE=InnoDB/i) && print;' mysqldump.sql

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;
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;

How would you do that in Java?

MYSQLI_INSERT_ID(3)							 1						       MYSQLI_INSERT_ID(3)

mysqli::$insert_id - Returns the auto generated id used in the last query

       Object oriented style

SYNOPSIS
mixed$mysqli->insert_id () DESCRIPTION
Procedural style mixed mysqli_insert_id (mysqli $link) The mysqli_insert_id(3) function returns the ID generated by a query on a table with a column having the AUTO_INCREMENT attribute. If the last query wasn't an INSERT or UPDATE statement or if the modified table does not have a column with the AUTO_INCREMENT attribute, this function will return zero. Note Performing an INSERT or UPDATE statement using the LAST_INSERT_ID() function will also modify the value returned by the mysqli_insert_id(3) function. PARAMETERS
o $ link -Procedural style only: A link identifier returned by mysqli_connect(3) or mysqli_init(3) RETURN VALUES
The value of the AUTO_INCREMENT field that was updated by the previous query. Returns zero if there was no previous query on the connec- tion or if the query did not update an AUTO_INCREMENT value. Note If the number is greater than maximal int value, mysqli_insert_id(3) will return a string. EXAMPLES
Example #1 $mysqli->insert_id example Object oriented style <?php $mysqli = new mysqli("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s ", mysqli_connect_error()); exit(); } $mysqli->query("CREATE TABLE myCity LIKE City"); $query = "INSERT INTO myCity VALUES (NULL, 'Stuttgart', 'DEU', 'Stuttgart', 617000)"; $mysqli->query($query); printf ("New Record has id %d. ", $mysqli->insert_id); /* drop table */ $mysqli->query("DROP TABLE myCity"); /* close connection */ $mysqli->close(); ?> Procedural style <?php $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s ", mysqli_connect_error()); exit(); } mysqli_query($link, "CREATE TABLE myCity LIKE City"); $query = "INSERT INTO myCity VALUES (NULL, 'Stuttgart', 'DEU', 'Stuttgart', 617000)"; mysqli_query($link, $query); printf ("New Record has id %d. ", mysqli_insert_id($link)); /* drop table */ mysqli_query($link, "DROP TABLE myCity"); /* close connection */ mysqli_close($link); ?> The above examples will output: New Record has id 1.
