(EXPERIMENTAL) Composes a SQL query client-side.
Defined in header <boost/mysql/format_sql.hpp>
std::string format_sql( const format_options& opts, constant_string_view format_str, std::initializer_list< format_arg > args);
Parses format_str as a
format string, substituting replacement fields (like {},
{1} or {name})
by formatted arguments, extracted from args.
opts is using to parse
the string and format string arguments.
Formatting is performed as if format_context::append_raw and format_context::append_value were called on a
context created by this function.
Strong guarantee. Memory allocations may throw. boost::system::system_error
is thrown if an error is found while formatting. See below for more info.
client_errc::invalid_encoding
if args contains a
string with byte sequences that can't be decoded with the current character
set.
client_errc::unformattable_value
if args contains a
floating-point value that is NaN or infinity.
formatter specializations.
client_errc::format_string_invalid_syntax
if format_str can't
be parsed as a format string.
client_errc::format_string_invalid_encoding
if format_str contains
byte byte sequences that can't be decoded with the current character
set.
client_errc::format_string_manual_auto_mix
if format_str contains
a mix of automatic ({})
and manual indexed ({1}) replacement
fields.
client_errc::format_arg_not_found
if an argument referenced by format_str
isn't present in args
(there aren't enough arguments or a named argument is not found).
This overload allows using named arguments.
