| DB_SUCCESS_LOCKED_REC | like DB_SUCCESS, but a new explicit record lock was created  | 
| DB_MISSING_HISTORY | required history data has been deleted due to lack of space in rollback segment  | 
| DB_MUST_GET_MORE_FILE_SPACE | the database has to be stopped and restarted with more file space  | 
| DB_TOO_BIG_RECORD | a record in an index would not fit on a compressed page, or it would become bigger than 1/2 free space in an uncompressed page frame  | 
| DB_LOCK_WAIT_TIMEOUT | lock wait lasted too long  | 
| DB_NO_REFERENCED_ROW | referenced key value not found for a foreign key in an insert or update of a row  | 
| DB_ROW_IS_REFERENCED | cannot delete or update a row because it contains a key value which is referenced  | 
| DB_CANNOT_ADD_CONSTRAINT | adding a foreign key constraint to a table failed  | 
| DB_CORRUPTION | data structure corruption noticed  | 
| DB_CANNOT_DROP_CONSTRAINT | dropping a foreign key constraint from a table failed  | 
| DB_NO_SAVEPOINT | no savepoint exists with the given name  | 
| DB_TABLESPACE_EXISTS | we cannot create a new single-table tablespace because a file of the same name already exists  | 
| DB_TABLESPACE_DELETED | tablespace was deleted or is being dropped right now  | 
| DB_LOCK_TABLE_FULL | lock structs have exhausted the buffer pool (for big transactions, InnoDB stores the lock structs in the buffer pool)  | 
| DB_FOREIGN_DUPLICATE_KEY | foreign key constraints activated by the operation would lead to a duplicate key in some table  | 
| DB_TOO_MANY_CONCURRENT_TRXS | when InnoDB runs out of the preconfigured undo slots, this can only happen when there are too many concurrent transactions  | 
| DB_UNSUPPORTED | when InnoDB sees any artefact or a feature that it can't recoginize or work with e.g., FT indexes created by a later version of the engine.  | 
| DB_INVALID_NULL | a NOT NULL column was found to be NULL during table rebuild  |

| DB_CHILD_NO_INDEX | the child (foreign) table does not have an index that contains the foreign keys as its prefix columns  | 
| DB_PARENT_NO_INDEX | the parent table does not have an index that contains the foreign keys as its prefix columns  | 
| DB_TOO_BIG_INDEX_COL | index column size exceeds maximum limit  | 
| DB_INDEX_CORRUPT | we have corrupted index  | 
| DB_UNDO_RECORD_TOO_BIG | the undo log record is too big  | 
| DB_READ_ONLY | Update operation attempted in a read-only transaction  | 
| DB_ONLINE_LOG_TOO_BIG | Modification log grew too big during online index creation  | 
| DB_IO_ERROR | Generic IO error  | 
| DB_IDENTIFIER_TOO_LONG | Identifier name too long  | 
| DB_FTS_EXCEED_RESULT_CACHE_LIMIT | FTS query memory exceeds result cache limit  | 
| DB_DICT_CHANGED | Some part of table dictionary has changed. Such as index dropped or foreign key dropped  | 
| DB_DATA_MISMATCH | Column update or read failed because the types mismatch  | 
| DB_SCHEMA_NOT_LOCKED | If an API function expects the schema to be locked in exclusive mode and if it's not then that API function will return this error code  | 
| DB_NOT_FOUND | Generic error code for "Not found" type of errors  |
