scala_spark _dataframe_hivecontext

Question

I have a hive table. It contain some one column as "query" and there are 4 records in it. I will read the hive using :

val query_hive=sqlContext.sql(s"select * from hive_query limit 1")

I need to use this query in another hive for the calculation.

I have tried this method:

val ouput=sqlContext.sql(s"$query_hive")

But I am getting an error. Can anybody suggest the solution for the same?

You can do this. You are not passing query correctly, just look it below:

scala> val query = "select * from src limit 1"
query: String = select * from src limit 1

scala> sql(s"""$query""").show
+---+-----+
|key|value|
+---+-----+
|  1|    a|
+---+-----+

Thanks.
