SqlCommandBuilder.GetDeleteCommand SqlCommandBuilder.GetDeleteCommand SqlCommandBuilder.GetDeleteCommand SqlCommandBuilder.GetDeleteCommand Method

Definition

Gets the automatically generated SqlCommand object required to perform deletions on the database.

Overloads

GetDeleteCommand() GetDeleteCommand() GetDeleteCommand() GetDeleteCommand()

Gets the automatically generated SqlCommand object required to perform deletions on the database.

GetDeleteCommand(Boolean) GetDeleteCommand(Boolean) GetDeleteCommand(Boolean) GetDeleteCommand(Boolean)

Gets the automatically generated SqlCommand object that is required to perform deletions on the database.

Remarks

An application can use the GetDeleteCommand method for informational or troubleshooting purposes because it returns the SqlCommand 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 CommandTimeout value, and then explicitly set that on the SqlDataAdapter.

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 when the application calls either 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 lets you force the OleDbCommandBuilder to generate parameters based on the column names instead. This succeeds only if the following conditions are met:
