#define array_elements | ( | a | ) |
Definition at line 431 of file definitions.h.
#define KEY_DEFAULT_PACK_LENGTH 8 |
Don't pack string keys shorter than this (if PACK_KEYS=1 isn't used).
Definition at line 174 of file definitions.h.
Referenced by drizzled::prepare_create_table().
#define MATCHING_ROWS_IN_OTHER_TABLE 10 |
Number of rows in a reference table when refereed through a not unique key. This value is only used when we don't know anything about the key distribution.
Definition at line 171 of file definitions.h.
Referenced by drizzled::best_access_path().
#define PROCESS_LIST_WIDTH 100 |
Characters shown for the command in 'show processlist'.

#define PSEUDO_TABLE_BITS |
Definition at line 77 of file definitions.h.
#define TIME_FOR_COMPARE 5 |
The following is used to decide if MySQL should use table scanning instead of reading with keys. The number says how many evaluation of the WHERE clause is comparable to reading one extra row from a table.

#define TIME_FOR_COMPARE_ROWID (TIME_FOR_COMPARE*2) |
Number of comparisons of table rowids equivalent to reading one row from a table.
