DeleteAll

This method is used to delete an array-of (and/or all) rows from the table.

Code Snippets

Below is the sample code that delete all the rows from the [dbo].[Person] table.

using (var connection = new SqlConnection(connectionString))
{
    var deletedRows = connection.DeleteAll<Person>();
}

Or you can target the list of primary keys.

using (var connection = new SqlConnection(connectionString))
{
    var primaryKeys = new [] { 10045, 11921, 12001 }; 
    var deletedRows = connection.DeleteAll<Person>(primaryKeys);
}

Targeting a Table

You can also target a specific table by passing the literal table name like below.

using (var connection = new SqlConnection(connectionString))
{
    var deletedRows = connection.DeleteAll("[dbo].[Person]");
}

Table Hints

To pass a hint, simply write the table-hints and pass it in the hints argument.

using (var connection = new SqlConnection(connectionString))
{
    var deletedRows = connection.DeleteAll<Person>(hints: "WITH (NOLOCK)");
}

Or, you can use the SqlServerTableHints class.

using (var connection = new SqlConnection(connectionString))
{
    var deletedRows = connection.DeleteAll<Person>(hints: SqlServerTableHints.TabLock);
}
