### クエリとバインド値の出力 | |
printf "*** QUERY ***\n%s\n\n\b*** BINDS ***\n%s\n\n", $sql, join(', ', @binds); | |
### 無理やりクエリにバインド値を当て込む場合。(perl 5.14.0以降のみ有効) | |
my $query_format = $sql =~ s/\?/\'\%s\'/gr; | |
my $raw_sql = sprintf($query_format, @binds); | |
printf "*** RAW_SQL ***\n%s\n\n", $raw_sql; | |
