(Deprecated) Starts a statement execution as a multi-function operation.
template<
class FieldViewFwdIterator
,
class CompletionToken>
auto
async_start_statement_execution(
const statement& stmt,
FieldViewFwdIterator params_first,
FieldViewFwdIterator params_last,
execution_state& st,
CompletionToken&& token);
Writes the execute request and reads the initial server response and
the column metadata, but not the generated rows or any subsequent resultsets,
if any. After this operation completes, st
will have execution_state::meta
populated.
If the operation generated any rows or more than one resultset, these
must be read (by using read_some_rows
and read_resultset_head
) before
engaging in any further network operation. Otherwise, the results are
undefined.
The statement actual parameters are passed as an iterator range. String parameters should be encoded using the connection's character set.
This function is only provided for backwards-compatibility. For new code,
please use start_execution
or async_start_execution
instead.
stmt.valid() == true
If CompletionToken
is
deferred (like use_awaitable
),
the caller must keep objects in the iterator range alive until the operation
is initiated.
The handler signature for this operation is void(boost::mysql::error_code)
.
