SpringでMySQLエラー Unknown column ' 値1 ' in 'field list'

Posted at

Spring Java の Entityで

Unknown column ' 値1 ' in 'field list'

が出てハマりました。

結論から言うと大文字が混ざっていたのが問題でした。

ターミナルからMySQLに直接SQLを流し込むと大文字でも正常に動作しますが、
Spring + Java のプログラムから呼び出そうとするとカラムがないというエラーになります。

field がない と特定の列名を指定してくる場合はカラムに日本語や大文字などが混ざっていないか注意しましょう。
