NAME

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.

       The following table includes options that are specific to ndb_drop_index. Additional descriptions follow the table. For options common to
       most MySQL Cluster programs (including ndb_drop_index), see Options Common to MySQL Cluster Programs(1).

	   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: 5.5.35-ndb-7.2.15
	   Type 'help;' or 'h' for help. Type 'c' to clear the buffer.
	   mysql> SHOW TABLES;
	   +------------------+
	   | Tables_in_ctest1 |
	   +------------------+
	   | a		      |

	   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.
