VistaDBCommand Constructor | Overloaded. |
Name | Description | |
---|---|---|
CommandText | Overridden. Gets or sets the text command to run against the data source. Gets or sets the text command to run against the data source. | |
CommandTimeout | Overridden. Gets or sets the wait time before terminating the attempt to execute a command and generating an error. Gets or sets the time to wait in seconds before stopping a command execution. This is not used in the current engine, but will be used in a future version. | |
CommandType | Overridden. Indicates or specifies how the System.Data.Common.DbCommand.CommandText property is interpreted. Indicates or specifies how the CommandText property is interpreted. VistaDB supports only Text and StoredProcedures command types. | |
Connection | Gets or sets the VistaDBConnection used by this VistaDBCommand. | |
Container | (Inherited from System.ComponentModel.Component) | |
DesignTimeVisible | Overridden. Gets or sets a value indicating whether the command object should be visible in a customized interface control. This property is not intended to be used in your code. It is used internally to support the designers. | |
HasDDLCommands | True if command has DDL commands | |
Parameters | Gets the collection of VistaDBParameter objects. | |
Site | (Inherited from System.ComponentModel.Component) | |
Transaction | Gets or sets the VistaDBTransaction within which this VistaDBCommand object executes. | |
UpdatedRowSource | Overridden. Gets or sets how command results are applied to the System.Data.DataRow when used by the Update method of a System.Data.Common.DbDataAdapter. Gets or sets how command results are applied to the DataRow when used by the Update method of a VistaDBDataAdapter. |
Name | Description | |
---|---|---|
CanRaiseEvents | (Inherited from System.ComponentModel.Component) | |
DbConnection | Overridden. Gets or sets the System.Data.Common.DbConnection used by this System.Data.Common.DbCommand. | |
DbParameterCollection | Overridden. Gets the collection of System.Data.Common.DbParameter objects. | |
DbTransaction | Overridden. Gets or sets the System.Data.Common.DbCommand.DbTransaction within which this System.Data.Common.DbCommand object executes. | |
DesignMode | (Inherited from System.ComponentModel.Component) | |
Events | (Inherited from System.ComponentModel.Component) |
Name | Description | |
---|---|---|
Cancel | Overridden. Attempts to cancels the execution of a System.Data.Common.DbCommand. Attempts to cancel the execution of a query, if no query is running this call does nothing. Cancel will also cause the VistaDBDataReader object to discard any unread rows. | |
CreateObjRef | Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from System.MarshalByRefObject) | |
CreateParameter | Creates a new instance of a VistaDBParameter object. | |
Dispose | Overloaded. Overridden. Dispose the object - then call the base object to tell it to release as well | |
ExecuteNonQuery | Overridden. Executes a SQL statement against a connection object. Executes a SQL statement against a connection object. | |
ExecuteNonQueryAsync | Overloaded. An asynchronous version of System.Data.Common.DbCommand.ExecuteNonQuery, which executes a SQL statement against a connection object. Invokes System.Data.Common.DbCommand.ExecuteNonQueryAsync(System.Threading.CancellationToken) with CancellationToken.None. (Inherited from System.Data.Common.DbCommand) | |
ExecuteReader | Overloaded. Executes the CommandText against the Connection, and returns a VistaDBDataReader. | |
ExecuteReaderAsync | Overloaded. Executes the CommandText against the Connection, and returns a VistaDBDataReader, asynchronously. | |
ExecuteScalar | Overridden. Executes the query and returns the first column of the first row in the result set returned by the query. All other columns and rows are ignored. Executes the query and returns the first column of the first row in the result set returned by the query. All other columns and rows are ignored. | |
ExecuteScalarAsync | Overloaded. An asynchronous version of System.Data.Common.DbCommand.ExecuteScalar, which executes the query and returns the first column of the first row in the result set returned by the query. All other columns and rows are ignored. Invokes System.Data.Common.DbCommand.ExecuteScalarAsync(System.Threading.CancellationToken) with CancellationToken.None. (Inherited from System.Data.Common.DbCommand) | |
GetLifetimeService | Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from System.MarshalByRefObject) | |
InitializeLifetimeService | Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from System.MarshalByRefObject) | |
Prepare | Overridden. Creates a prepared (or compiled) version of the command on the data source. Creates a prepared version of the command on the data source. | |
ResetCommandTimeout | Resets the CommandTimeout to its default value. | |
ToString | (Inherited from System.ComponentModel.Component) |
Name | Description | |
---|---|---|
CreateDbParameter | Overridden. Creates a new instance of a System.Data.Common.DbParameter object. | |
ExecuteDbDataReader | Overridden. Executes the command text against the connection. | |
ExecuteDbDataReaderAsync | Overridden. Providers should implement this method to provide a non-default implementation for Overload overloads. The default implementation invokes the synchronous System.Data.Common.DbCommand.ExecuteReader method and returns a completed task, blocking the calling thread. The default implementation will return a cancelled task if passed an already cancelled cancellation token. Exceptions thrown by ExecuteReader will be communicated via the returned Task Exception property. This method accepts a cancellation token that can be used to request the operation to be cancelled early. Implementations may ignore this request.Providers should implement this method to provide a non-default implementation for System.Data.Common.DbCommand.ExecuteReader overloads.The default implementation invokes the synchronous System.Data.Common.DbCommand.ExecuteReader method and returns a completed task, blocking the calling thread.
