Boost C++ Libraries

(Deprecated - will be removed in Boost 1.86) Starts a statement execution as a multi-function operation.

Synopsis

template<
    class WritableFieldTuple,
    class EnableIf = typename std::enable_if<detail::is_writable_field_tuple<WritableFieldTuple>::value>::type>
void
start_statement_execution(
    const statement& stmt,
    const WritableFieldTuple& params,
    execution_state& st);

Description

Writes the execute request and reads the initial server response and the column metadata, but not the generated rows or subsequent resultsets, if any. After this operation completes, st will have execution_state::meta populated. Metadata will be populated according to this->meta_mode().

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 (params) are passed as a std::tuple of elements. String parameters should be encoded using the connection's character set.

Deprecation warning

This function is deprecated and will be removed in Boost 1.86. Please use execute or async_execute instead.
