OracleCommandBuilder.GetUpdateCommand Method

Definition

Namespace:

System.Data.OracleClient

Assembly:

System.Data.OracleClient.dll

Gets the automatically generated OracleCommand object required to perform updates on the database.

Overloads

GetUpdateCommand()	Gets the automatically generated OracleCommand object required to perform updates on the database.
GetUpdateCommand(Boolean)	Gets the automatically generated OracleCommand object required to perform updates on the database.

Remarks

You can use the GetUpdateCommand method for informational or troubleshooting purposes because it returns the OracleCommand object to be executed.

You can also use GetUpdateCommand as the basis of a modified command. For example, you might call GetUpdateCommand and modify the CommandText value, and then explicitly set that on the OracleDataAdapter.

The SQL statements are first generated when the application calls either Update or GetUpdateCommand.

For more information, see Generating Commands with CommandBuilders.

GetUpdateCommand()

Gets the automatically generated OracleCommand object required to perform updates on the database.

public:

public System.Data.OracleClient.OracleCommand GetUpdateCommand ();

override this.GetUpdateCommand : unit -> System.Data.OracleClient.OracleCommand

Public Function GetUpdateCommand () As OracleCommand

Returns

OracleCommand

The automatically generated OracleCommand object required to perform updates.

GetUpdateCommand(Boolean)

Gets the automatically generated OracleCommand object required to perform updates on the database.

public:
 System::Data::OracleClient::OracleCommand ^ GetUpdateCommand(bool useColumnsForParameterNames);

public System.Data.OracleClient.OracleCommand GetUpdateCommand (bool useColumnsForParameterNames);

override this.GetUpdateCommand : bool -> System.Data.OracleClient.OracleCommand

Public Function GetUpdateCommand (useColumnsForParameterNames As Boolean) As OracleCommand

Parameters

useColumnsForParameterNames

Boolean

true to generate parameter names matching column names, if possible. false to generate @p1, @p2, and so on.

Returns

OracleCommand

The automatically generated OracleCommand object required to perform updates.

The SQL statements are first generated when the application calls either Update or GetUpdateCommand.

The default behavior, when generating parameter names, is to use @p1, @p2, and so on, for the various parameters. Passing true for the useColumnsForParameterNames parameter allows you to force the OracleCommandBuilder to generate parameters based on the column names instead. This succeeds only if the following conditions are met:

• The ParameterNameMaxLength has been specified and its length is equal to or greater than the generated parameter name.

• The generated parameter name meets the criteria specified in the ParameterNamePattern regular expression.

• A ParameterMarkerFormat is specified.
