DbCommandBuilder.GetDeleteCommand Method (Boolean)

Gets the automatically generated DbCommand object required to perform deletions at the data source, optionally using columns for parameter names.

Namespace:  System.Data.Common
Assembly:  System.Data (in System.Data.dll)

'Declaration
Public Function GetDeleteCommand ( _
	useColumnsForParameterNames As Boolean _
) As DbCommand

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.Common.DbCommand
The automatically generated DbCommand object required to perform deletions.

An application can use the GetDeleteCommand method for informational or troubleshooting purposes because it returns the DbCommand object to be executed.

You can also use GetDeleteCommand as the basis of a modified command. For example, you might call GetDeleteCommand and modify the command text, and then explicitly set that on the DbDataAdapter.

After the SQL statement is first generated, the application must explicitly call RefreshSchema if it changes the statement in any way. Otherwise, the GetDeleteCommand will still be using information from the previous statement, which might not be correct. The SQL statements are first generated either when the application calls Update or GetDeleteCommand.

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:
