#define MDB_SUCCESS 0

Successful result

#define MDB_KEYEXIST (-30799)

key/data pair already exists

#define MDB_NOTFOUND (-30798)

key/data pair not found (EOF)

#define MDB_PAGE_NOTFOUND (-30797)

Requested page not found - this usually indicates corruption

#define MDB_CORRUPTED (-30796)

Located page was wrong type

#define MDB_PANIC (-30795)

Update of meta page failed or environment had fatal error

#define MDB_VERSION_MISMATCH (-30794)

Environment version mismatch

#define MDB_INVALID (-30793)

File is not a valid LMDB file

#define MDB_MAP_FULL (-30792)

Environment mapsize reached

#define MDB_DBS_FULL (-30791)

Environment maxdbs reached

#define MDB_READERS_FULL (-30790)

Environment maxreaders reached

#define MDB_TLS_FULL (-30789)

Too many TLS keys in use - Windows only

#define MDB_TXN_FULL (-30788)

Txn has too many dirty pages

#define MDB_CURSOR_FULL (-30787)

Cursor stack too deep - internal error

#define MDB_PAGE_FULL (-30786)

Page has not enough space - internal error

#define MDB_MAP_RESIZED (-30785)

Database contents grew beyond environment mapsize

#define MDB_INCOMPATIBLE (-30784)

Operation and DB incompatible, or DB type changed. This can mean:

• The operation expects an MDB_DUPSORT / MDB_DUPFIXED database.
• Opening a named DB when the unnamed DB has MDB_DUPSORT / MDB_INTEGERKEY.
• Accessing a data record as a database, or vice versa.
• The database was dropped and recreated with different flags.

#define MDB_BAD_RSLOT (-30783)

Invalid reuse of reader locktable slot

#define MDB_BAD_TXN (-30782)

Transaction must abort, has a child, or is invalid

#define MDB_BAD_VALSIZE (-30781)

Unsupported size of key/DB name/data, or wrong DUPFIXED size

#define MDB_BAD_DBI (-30780)

The specified DBI was changed unexpectedly

#define MDB_LAST_ERRCODE MDB_BAD_DBI

The last defined error code
