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> SHOW TABLES;
     +------------------+
     | Tables_in_ctest1 |
     +------------------+
     | a		|
     | bt1		|
     | bt2		|
     | dogs		|
     | employees	|
     | fish		|
     +------------------+
     6 rows in set (0.00 sec)
     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.
