const char** ha_ndbinfo::bas_ext ( ) const [inline, virtual]

If frm_error() is called then we will use this to find out what file extentions exist for the storage engine. This is also used by the default rename_table and delete_table method in

For engines that have two file name extentions (separate meta/index file and data file), the order of elements is relevant. First element of engine file name extentions array should be meta/index file extention. Second element - data file extention. This order is assumed by prepare_for_repair() when REPAIR TABLE ... USE_FRM is issued.

Implements handler.

bool ha_ndbinfo::get_error_message ( int  error,
String buf 
) [virtual]

Return an error message specific to this handler.

errorerror code previously returned by handler
bufpointer to String where to add error message
Returns true if this is a temporary error

Reimplemented from handler.

int ha_ndbinfo::rnd_init ( bool  scan) [virtual]

rnd_init() can be called two times without rnd_end() in between (it only makes sense if scan=1). then the second call should prepare for the new table scan (e.g if rnd_init allocates the cursor, second call should position it to the start of the table, no need to deallocate and allocate it again

Implements handler.

int ha_ndbinfo::rnd_next ( uchar *  buf) [virtual]

Implements handler.

int ha_ndbinfo::rnd_pos ( uchar *  buf,
uchar *  pos 
) [virtual]
See also:

Implements handler.

THR_LOCK_DATA** ha_ndbinfo::store_lock ( THD *  thd,
enum thr_lock_type  lock_type 
) [inline, virtual]

Is not invoked for non-transactional temporary tables.

store_lock() can return more than one lock if the table is MERGE or partitioned.
that one can NOT rely on table->in_use in store_lock(). It may refer to a different thread if called from mysql_lock_abort_for_thread().
If the table is MERGE, store_lock() can return less locks than lock_count() claimed. This can happen when the MERGE children are not attached when this is called from another thread.

Implements handler.

uint8 ha_ndbinfo::table_cache_type ( ) [inline, virtual]

Type of table for caching query

Reimplemented from handler.

const char* ha_ndbinfo::table_type ( ) const [inline, virtual]

The following can be called without an open handler

Implements handler.
