SQLのLIKEとILIKE

Last updated at Posted at 2021-06-17
  • LIKEは、case sensitive
  • ILIKEは case insensitive

その他

patternがパーセント記号もしくはアンダースコアを含んでいない場合patternは自身の文字列そのものです。この場合LIKE式は等号演算子のように振舞います。patternの中にあるアンダースコア（_）は任意の一文字とのマッチを意味し、パーセント記号（%）は0文字以上の文字列とのマッチを意味します。(From https://www.postgresql.jp/document/8.2/html/functions-matching.html)
