NDB_DROP_INDEX(1) MySQL Database System NDB_DROP_INDEX(1)NAMEndb_drop_index - drop index from NDB table
SYNOPSISndb_drop_index options
DESCRIPTIONndb_drop_index drops the specified index from an NDB table. It is
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:
ndb_drop_index-c connect_string table_name index -d db_name
The statement shown above drops the index named index from the table in
the database.
Additional Options: 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.
