(was: {code:sql}select catalog.sales.em^ from catalog.sales.emp{code}
simplifies to
{code:sql}select catalog.sales. _sugest_ from catalog.sales.emp{code}
and validator produces the following exception:

It looks more like a bug in SqlValidator)
> SqlAdvisor.getCompletionHints does not work for nested identifiers sub-match

> Key: CALCITE-2434
> URL: https://issues.apache.org/jira/browse/CALCITE-2434
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.17.0
> Reporter: Vladimir Sitnikov
> Assignee: Vladimir Sitnikov
> Priority: Major
>
> Test (SqlAdvisorTest):
> {code:java} @Test public void testNestSchema() throws Exception {
> String sql;
> sql = "select * from sales.n^";
> assertComplete(
> sql,
> ...);
> }
> {code}
> Expected output: "SALES.NEST" schema and tables inside and so on
> Actual output: empty.
> The thing is it properly uses {{n}} for prefix search, however it uses
> {{hint.toString()}} and it fails for multi-name identifiers:
> {code:java} // Regular identifier. Case-insensitive match.
> for (SqlMoniker hint : completionHints) {
> String cname = hint.toString();
> if ((cname.length() >= word.length())
> && cname.substring(0, word.length()).equalsIgnoreCase(word)) {
> result.add(hint);
> }
> }
> {code}
> Hints are like "CATALOG.SALES.NEST", and they fail {{cname.substring(0,
> word.length()).equalsIgnoreCase(word)}} check
