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

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.
