DESCRIPTION

recommended that you use this utility only as an example for writing
NDB API applications--see the Warning later in this section for
details.
Usage

The statement shown above drops the index named index from the table in
the database.
Additional Options
.PP None that are specific to this application.
Warning
Operations performed on Cluster table indexes using the NDB API are
not visible to MySQL and make the table unusable by a MySQL server.
If you use this program to drop an index, then try to access the
table from an SQL node, an error results, as shown here:
shell> ./ndb_drop_index -c localhost dogs ix -d ctest1
Dropping index dogs/idx...OK
NDBT_ProgramExit: 0 - OK
shell> ./mysql -u jon -p ctest1
Enter password: *******

In such a case, your only option for making the table available to
MySQL again is to drop the table and re-create it. You can use either
the SQL statementDROP TABLE or the ndb_drop_table utility (see
ndb_drop_table(1)) to drop the table.
