NDB_DROP_INDEX(1)            MySQL Database System           NDB_DROP_INDEX(1)

NAME
       ndb_drop_index - drop index from NDB table

SYNOPSIS
       ndb_drop_index options

DESCRIPTION
       ndb_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: *******
          Reading table information for completion of table and column names
          You can turn off this feature to get a quicker startup with -A
          Welcome to the MySQL monitor.  Commands end with ; or \g.
          Your MySQL connection id is 7 to server version: 5.1.12-beta-20060817
          Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

          mysql> SELECT * FROM dogs;
          ERROR 1296 (HY000): Got error 4243 'Index not found' from NDBCLUSTER

       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.
