Creates a query with parameters (client-side SQL formatting) that can be executed.
Defined in header <boost/mysql/with_params.hpp>
template<
class... FormattableOrRefWrapper>
auto
with_params(
constant_string_view
query,
FormattableOrRefWrapper&&... args);
Creates a with_params_t
object by packing
the supplied arguments into a tuple, calling std::make_tuple
.
As per std::make_tuple
, parameters will be decay-copied
into the resulting object. This behavior can be disabled by passing std::reference_wrapper
objects, which are transformed into references.
This function does not inspect the supplied query string and arguments. Errors like missing format arguments are detected when the resulting object is executed. This function does not involve communication with the server.
The passed args
must either
satisfy Formattable
, or be
std::reference_wrapper<T>
with
T
satisfying Formattable
.
See with_params_t
for details on how the execution request works.
Strong guarantee. Any exception thrown when copying args
will be propagated.
