PostgreSQL - text Array contains value similar to

由 六月ゝ 毕业季﹏ 提交于 2019-11-28 12:38:37
I'm trying to get rows where a column of type text[] contains a value similar to some user input. What I've thought and done so far is to use the 'ANY' and 'LIKE ' operator like this: select * from someTable where '%someInput%' LIKE ANY(someColum); But it doesn't work. The query returns the same values as that this query: select * from someTable where 'someInput' = ANY(someColum); I've got good a result using the unnest() function in a subquery but I need to query this in WHERE clause if possible. WHY doesn't the LIKE operator work with the ANY operator and I don't get any errors? I thought

scala - Any vs underscore in generics

What is the different between the following Generics definitions in Scala: class Foo[T <: List[_]] and class Bar[T <: List[Any]] My gut tells me they are about the same but that the latter is more explicit. I am finding cases where the former compiles but the latter doesn't, but can't put my finger on the exact difference. Thanks! Edit: Can I throw another into the mix? class Baz[T <: List[_ <: Any]] OK, I figured I should have my take on it, instead of just posting comments. Sorry, this is going to be long, if you want the TL;DR skip to the end. As Randall Schulz said, here _ is a shorthand
