MySqlストアドプロシージャ - フィールドリストの不明な列

Question

ストアドプロシージャの実行中に問題が発生しています。私はこのクエリを実行することができます

select 
bit_count(cast(conv(substr('00d803fc07fc1ff807f8027f203f607b01fe03ff01fc03b8077f07780fb94039', 1, 16), 16, 10) as unsigned)^cast(conv(substr('00d803fc07fc1ff807f8027f203f607b00fe03ff01fe03b8077f07780fb94039', 1, 16), 16, 10) as unsigned)) + 
bit_count(cast(conv(substr('00d803fc07fc1ff807f8027f203f607b01fe03ff01fc03b8077f07780fb94039', 17, 16), 16, 10) as unsigned)^cast(conv(substr('00d803fc07fc1ff807f8027f203f607b00fe03ff01fe03b8077f07780fb94039', 17, 16), 16, 10) as unsigned)) + 
bit_count(cast(conv(substr('00d803fc07fc1ff807f8027f203f607b01fe03ff01fc03b8077f07780fb94039', 33, 16), 16, 10) as unsigned)^cast(conv(substr('00d803fc07fc1ff807f8027f203f607b00fe03ff01fe03b8077f07780fb94039', 33, 16), 16, 10) as unsigned)) + 
bit_count(cast(conv(substr('00d803fc07fc1ff807f8027f203f607b01fe03ff01fc03b8077f07780fb94039', 49, 16), 16, 10) as unsigned)^cast(conv(substr('00d803fc07fc1ff807f8027f203f607b00fe03ff01fe03b8077f07780fb94039', 49, 16), 16, 10) as unsigned)); 

しかし、私は、ストアドプロシージャにこれを作るしようとすると、それは「不明な列」のエラーで失敗します。

は私が間違って何をしているのですか？私は、同じ結果を持つselect文でfp1とfp2（ 'fp1'）を一重引用符で囲みてみました。

ありがとうございます！

Answer 1

私はそれを理解しました。 CALL文には一重引用符が必要でした。 ARGH！

call Distance('00d803fc07fc1ff807f8027f203f607b01fe03ff01fc03b8077f07780fb94039','00d803fc07fc1ff807f8027f203f607b01fe03ff01fc03b8077f07780fb94039');
