NDB_DROP_INDEX(1) MySQL Database System NDB_DROP_INDEX(1)
NAME
ndb_drop_index - drop index from an 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.
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).
Table 17.18. ndb_drop_index Options and Variables: MySQL Cluster NDB 7.2
+--------------------------+-----------------------------------+-------------------------------------+
|Format | Description | Added / Removed |
+--------------------------+-----------------------------------+-------------------------------------+
| | Name of the database in which the | |
| --database=dbname, | table is found | All MySQL 5.5 based releases |
| | | |
| -d | | |
+--------------------------+-----------------------------------+-------------------------------------+
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.

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.
