How about ~starts, ~ends and ~contains?

[hrach]

@JanTvrdik yes, definitely, if this form will be chosen.

@matej21 suggested something like 'column' => Expr::startsWith($foo), which is actually on my radar too because I'd like to support non-value expression on the right side.

[JanTvrdik]

👍 for 'column' => Expr::startsWith($foo),

[hrach]

The final chosen syntax:

...->findBy(['title~' => LikeExpression::raw('Book%')]);
...->findBy(['title~' => LikeExpression::startsWith('Book')]);
...->findBy(['title~' => LikeExpression::endsWith('Book')]);
...->findBy(['title~' => LikeExpression::contains('Book')]);
