SumAll

This method is used to compute the sum value of the target field.

Code Snippets

Below is the sample code that returns the sum value of the column Value from a [dbo].[Sales] table.

using (var connection = new SqlConnection(connectionString))
{
    var expenses = connection.SumAll<Sales>(e => e.Value);
}

Targeting a Table

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

using (var connection = new SqlConnection(connectionString))
{
    var expenses = connection.SumAll("[dbo].[Sales]",
        Field.From("Value"));
}

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 expenses = connection.SumAll<Sales>(e => e.Value,
        hints: "WITH (NOLOCK)");
}

Or, you can use the SqlServerTableHints class.

using (var connection = new SqlConnection(connectionString))
{
    var expenses = connection.SumAll<Sales>(e => e.Value,
        hints: SqlServerTableHints.NoLock);
}
