----------------------------------
Summary: Resolve column with full qualified names: db.table.column
Key: SPARK-12820
URL: https://issues.apache.org/jira/browse/SPARK-12820
Project: Spark
Issue Type: New Feature
Components: SQL
Reporter: zhichao-li
Priority: Minor
Currently spark only support to specify col name like: `table.col`, or `col` in
projection, but it's very common that user use `db.table.col` especially when
join table across database.
Hive doesn't support this for now but it has been used in lot of other
traditional db like mysql.
