var (
	// ErrTableNotExist indicates that there is no such table.
	ErrTableNotExist = fmt.Errorf("collection/table does not exist")

	// ErrSchemaNotExist indicates that there is no such schema.
	ErrSchemaNotExist = fmt.Errorf("database/schema does not exist")

	// ErrSchemaAlreadyExist indicates that a schema already exists.
	ErrSchemaAlreadyExist = fmt.Errorf("database/schema already exists")

	// ErrCollectionAlreadyExist indicates that a collection already exists.
	ErrCollectionAlreadyExist = fmt.Errorf("collection/table already exists")

	// ErrInvalidCollectionName indicates that a collection didn't pass name checks.
	ErrInvalidCollectionName = fmt.Errorf("invalid FerretDB collection name")

	// ErrInvalidDatabaseName indicates that a database didn't pass name checks.
	ErrInvalidDatabaseName = fmt.Errorf("invalid FerretDB database name")
)

Errors are wrapped with lazyerrors.Error, so the caller needs to use errors.Is to check the error, for example, errors.Is(err, ErrSchemaNotExist).

var Errors = map[int]error{
	259: ErrTableNotExist,
	288: ErrCollectionAlreadyExist,
	362: ErrSchemaNotExist,
	386: ErrSchemaAlreadyExist,
}

Errors from HanaDB.
