MySQLのINは文字列の上限に依存する。

SQLのIN句はDBによって異なる。
Oracleが1000件なのはそこそこ有名だと思うが、MySQLはどうなのか？

## Mysqlは最大文字列数に依存する
MySQLはIN句の指定はないが、クエリの上限サイズには引っ掛かる。
つまり、クエリの文字列が許容範囲を超えてしまった場合はダメということです。

## 試してみる
手元の環境で、クエリの上限サイズを変更してみる。
まずは現設定を確認。

最大サイズを変えてみる。

さて、本当に文字列サイズに依存するかを調査しよう。
ひとまずIN句に指定する文字列を1000文字にしてみた。
```
//適当な1000文字
ABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEFGABCDEF
```

計算で行けば、17個IN句を指定すればエラーになるはず。試してみよう。

)

Error Code: 1153. Got a packet bigger than 'max_allowed_packet' bytes	0.000 sec
```

やはり、エラーが出た。
従って、クエリの上限サイズに依存するというのは本当だった。

## 注意点
MySQLでIN句を指定する場合は、以下のコマンドでクエリの上限サイズを調べてから
そのサイズに余裕ができるように設計しよう。
`show variables like 'max_allowed_packet'`
