OracleCommandBuilder::GetUpdateCommand Method (Boolean)
Gets the automatically generated OracleCommand object required to perform updates on the database.
Assembly: System.Data.OracleClient (in System.Data.OracleClient.dll)
Parameters
- useColumnsForParameterNames
-
Type:
System::Boolean
If true, generate parameter names matching column names, if possible. If false, generate @p1, @p2, and so on.
Return Value
Type: System.Data.OracleClient::OracleCommand^The automatically generated OracleCommand object required to perform updates.
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.
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 DbCommandBuilder 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.
