Review Comment:
if u want convert to `ProcedureName like <pattern>` u should coding like
```java
whereExpr = Sets.newHashSet(new Like(new UnboundSlot("ProcedureName"),
getExpression(ctx.pattern)));
```

Review Comment:
u add this class only want to get like right child?
u could get it easily by
```
Collection<Experssion> patterns =
whereExpr.stream().filter(Like.class::isInstance).map(e ->
e.child(1)).collect(....);
```

Review Comment:
whereExprConst and valueExprConst could merge into one set
