[jira] [Updated] (HIVE-6687) JDBC ResultSet fails to get value by
qualified projection name
[ https://issues.apache.org/jira/browse/HIVE-6687?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Laljo John Pullokkaran updated HIVE-6687:
-----------------------------------------
Description:
Getting value from result set using fully qualified name would throw exception. Only solution today is to use position of the column as opposed to column label.
String sql = "select r1.x, r2.x from r1 join r2 on r1.y=r2.y";
ResultSet res = stmt.executeQuery(sql);
res.getInt("r1.x");
res.getInt("r1.x"); would throw exception unknown column even though sql specifies it.
Fix is to fix resultsetschema in semantic analyzer.
