Function like 

pub fn like<'a, V, L, R>(
    left: L,
    pattern: R,
) -> SQLExpr<'a, V, Bool, NonNull, Scalar>
where
    V: SQLParam + 'a,
    L: Expr<'a, V>,
    R: Expr<'a, V>,
    L::SQLType: Textual,
    R::SQLType: Textual,

LIKE pattern matching.

Requires both operands to be textual types (TEXT, VARCHAR).

Type Safety

// ✅ OK: Text column with text pattern
like(users.name, "%Alice%");

// ❌ Compile error: Int is not Textual
like(users.id, "%123%");
