## Example 

Display version information and exit. 

First we create an NDB  table in the test  database, using the CREATE TABLE  statement shown here: 

USE test; CREATE TABLE btest ( c0 BIGINT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY, c1 TEXT, c2 BLOB ) ENGINE=NDB; 

Then we insert a few rows into this table, using a series of statements similar to this one: 

INSERT INTO btest VALUES (NULL, ’x’, REPEAT(’x’, 1000)); 

When run with --check-orphans  against this table, ndb_blob_tool  generates the following output: 

shell> ndb_blob_tool --check-orphans --verbose -d test btest
