Class Fields

static var ABORT_ERR:Int

A request was aborted, for example, through a call to IDBTransaction.abort.

static var CONSTRAINT_ERR:Int

A mutation operation in the transaction failed because a constraint was not satisfied. For example, an object, such as an object store or index, already exists and a request attempted to create a new one.

static var DATA_ERR:Int

Data provided to an operation does not meet requirements.

static var NON_TRANSIENT_ERR:Int

An operation was not allowed on an object. Unless the cause of the error is corrected, retrying the same operation would result in failure.

static var NOT_ALLOWED_ERR:Int

An operation was called on an object where it is not allowed or at a time when it is not allowed. It also occurs if a request is made on a source object that has been deleted or removed.

More specific variants of this error includes: TRANSACTION_INACTIVE_ERR and READ_ONLY_ERR.

static var NOT_FOUND_ERR:Int

The operation failed, because the requested database object could not be found; for example, an object store did not exist but was being opened.

static var NO_ERR:Int

static var QUOTA_ERR:Int

Either there's not enough remaining storage space or the storage quota was reached and the user declined to give more space to the database.

static var READ_ONLY_ERR:Int

A mutation operation was attempted in a READ_ONLY transaction.

static var TIMEOUT_ERR:Int

A lock for the transaction could not be obtained in a reasonable time.

static var TRANSACTION_INACTIVE_ERR:Int

A request was made against a transaction that is either not currently active or is already finished.

static var UNKNOWN_ERR:Int

The operation failed for reasons unrelated to the database itself, and it is not covered by any other error code; for example, a failure due to disk IO errors.

static var VER_ERR:Int

A request to open a database with a version lower than the one it already has. This can only happen with IDBOpenDBRequest.
