/// @file mysql_query_macros_dhcp.h
/// Collection of common macros defining MySQL prepared statements used
/// to manage Kea DHCP configuration in the database.
///
/// Some of the macros are DHCPv4 specific, other are DHCPv6 specific.
/// Some macros are common for both DHCP server types. The first
/// parameter @c table_prefix should be set to @c dhcp4 or @c dhcp6,
/// depending which DHCP server type it relates to. Provided value
/// is used as a prefix for MySQL table names. For example, if the
/// prefix is set to @c dhcp4, the table name referred to in the
/// query may be dhcp4_subnet etc. The second argument in the variadic
/// macro is a part of the WHERE clause in the MySQL query. The fixed
/// part of the WHERE clause is included in the macro.

/// @todo Update queries to also fetch server tags to associate
/// returned configuration elements with particular servers.
