Description

I raised question in
https://stackoverflow.com/questions/44642403/minus-logic-implementation-not-working-with-spark-scala

==== is working fine for Join two table with multiple key, But equalTo is not working when i use to join second key.

You can find both working and not working query with error message below

Working Query:
val ft = spark.sql("select * from " + targetTable)
val stg = spark.sql("select * from " + stgTable)
val result = ft.join ( stg, columnList.length
match {
case 2 => ft(columnList(0)) equalTo stg(columnList(0)) and
ft(columnList(1))*=== *stg(columnList(1))
case 1 => ft(columnList(0)) equalTo stg(columnList(0))
}, "left_outer").where(stg(columnList(0)).isNull)


Not Working Query :
val result = ft.join ( stg, columnList.length
match {
case 2 => ft(columnList(0)) equalTo stg(columnList(0)) and
ft(columnList(1)) equalTo stg(columnList(1))
case 1 => ft(columnList(0)) *equalTo *stg(columnList(0))
}, "left_outer").where(stg(columnList(0)).isNull)

Error Message:

column used for filtering the not modified records in target table is : order_id
Exception in thread "main" org.apache.spark.sql.AnalysisException: cannot resolve '((order_id = order_id) && order_product)' due to data type mismatch: differing types in '((order_id = order_id) && order_product)' (boolean and string).;
