connection::query (1 of 2 overloads)

Executes a SQL text query.

Synopsis
void
query(
    string_view query_string,
    results& result,
    error_code&,
    diagnostics&);
Description

Sends query_string to the server for execution and reads the response into result. query_string should be encoded using the connection's character set.

After this operation completes successfully, result.has_value() == true.

Metadata in result will be populated according to this->meta_mode().

Security

If you compose query_string by concatenating strings manually, your code is vulnerable to SQL injection attacks. If your query contains patameters unknown at compile time, use prepared statements instead of this function.
