void
execute_statement(
const statement& stmt,
const FieldLikeTuple& params,
results& result,
error_code& err,
diagnostics& diag);
Executes a statement with the given parameters and reads the response
into result.
After this operation completes successfully, result.has_value() == true.
The statement actual parameters (params)
are passed as a std::tuple of elements. See the FieldLikeTuple concept defition for
more info. You should pass exactly as many parameters as this->num_params(),
or the operation will fail with an error. String parameters should be
encoded using the connection's character set.
Metadata in result will
be populated according to conn.meta_mode(), where conn
is the connection that prepared this statement.
stmt.valid() == true
