    Class AdbExecuteNonQueryWorker

    A worker that executes a query in an SQL database without returning any result set (i.e. INSERT, UPDATE, DELETE and DML statements). The RecordsAffected property is however set when the query finishes.

    Also see SQL Database Access, as well as AdbTableNonQueryWorker and AdbExecuteScalarWorker<TResult>.

    Constructors

    AdbExecuteNonQueryWorker(WorkerParent, String, AdbCommandBuilder)

    Initializes a new instance of the AdbExecuteNonQueryWorker worker. It executes a query in an SQL database without returning any result set (i.e. INSERT, UPDATE, DELETE and DML statements).

    Type Name Description
    WorkerParent workerParent

    The parent worker or worker system that the new child worker will be added to. Cannot be null.

    String workerName

    Name of the worker.

    Set to a prefix plus a trailing "/" (e.g. "MyPrefix-/") to generate a unique name from the prefix plus an increasing number starting at 1.

    While less useful, set to null, whitespace or "/" to generate a unique name from the worker type plus an increasing number starting at 1.

    The name cannot otherwise contain "/", and cannot start with double underscore "__".

    Property Value
    Type Description
    AdbCommandBuilder
    Exceptions
    Type Condition
    InvalidOperationException

    Cannot set the value after the worker has started running.

    RecordsAffected

    Gets the number of records affected by an UPDATE, INSERT, or DELETE query. For all other types of statements, the return value is -1. Only available after the worker has completed successfully.

    Note: This property is thread-safe.

    Declaration
    public int RecordsAffected { get; }
    Property Value

    Methods

    RunAsync()

    This method can be overridden to add custom functionality to the derived worker that runs before and after the row processing. In this case, the base class base.RunAsync() must be called for the worker to function correctly.

    Typically, this worker is used without overriding this method.

    Declaration
    protected override Task<OutcomeStatus> RunAsync()
    Returns
    Type Description
    Task<OutcomeStatus>

    A Task describing the success or failure of the worker. An asynchronous async implementation would e.g. return OutcomeStatus.Succeeded on success, while a synchronous implementation would return OutcomeStatus.SucceededTask.

    Overrides
    WorkerParent.RunAsync()
