> For Sql:
> {code}
> val sql = "SELECT c, count(a) OVER (ORDER BY proctime ROWS BETWEEN 2 preceding AND CURRENT ROW) as cnt1 CURRENT ROW from MyTable"
> {code}
> The alias `cnt1` The alias did not take effect when we generated the plan string.  But we can using the alias in outer layer query, for example:
> {code}
> val sql = "SELECT cnt1 from (SELECT c, count(a) OVER (ORDER BY proctime ROWS BETWEEN 2 preceding AND CURRENT ROW) as cnt1 CURRENT ROW from MyTable)"
> {code}
> So in this JIRA. we just fix the test case for 1.3 release. In another JIRA. will improve the alias.
