static_results::info

Returns additional text information about the execution of the SQL statement.

Synopsis
template<
    std::size_t I = 0>
string_view
info() const;
Description

The format of this information is documented by MySQL here.

The returned string always uses ASCII encoding, regardless of the connection's character set.

Template Parameters

Type

Description

I

Resultset index. For operations returning more than one resultset, you can explicitly specify this parameter to obtain the value for the i-th resultset. If left unspecified, the value for the first resultset is returned.

Preconditions

this->has_value() == true

Exception safety

No-throw guarantee.

Object lifetimes

This function returns a view object, with reference semantics. The returned view points into memory owned by *this, and will be valid as long as *this or an object move-constructed from *this are alive.

Complexity

Constant.
