select composition from `drugs` where composition regexp "^Diclofenac([^)])"

我想寻找药物，其中组合物以Diclofenac（）开头，然后是＆＃34;，＃34;其次是硫代秋水仙碱苷（）。试过以下但结果为零。

select composition from `drugs` where composition regexp "^Diclofenac([^)]),Thiocolchicoside([^)])"

Answer 1

select composition from `drugs` where composition regexp "^Diclofenac\\([^)]+\\),Thiocolchicoside\\([^)]+\\)$"

除了添加＆＃39; +＆＃39;为了匹配多个非右支撑字符，即[^]]，你需要转义＆＃39;（＆＃39;，因为它在正则表达式中有特殊含义

Answer 2

尝试此模式^Diclofenac(.*,Thiocolchicoside\(.*\))

.*,表示,

之前的任何内容

\(.*\)表示（括号中的任何内容）

Mysql regexp返回零结果
