        QueryParameterCollection parameters

    Type Description

    Remarks

    Use the ExecuteNonQueryAsync method to execute SQL statements that do not produce result sets, such as UPDATE, INSERT, and DELETE statements.

    Use QueryParameterCollection to pass strongly-typed parameters. See examples here: Always Encrypted (SQL Server only).

    To learn more about executing SQL statements in XPO, refer to Direct SQL Queries.

    Note

    The ExecuteNonQueryAsync method sends statements directly, so the correct statement syntax and parameter names format depends on a particular database server.
