----------------------------------------
Summary: select query failure when substring on dictionary column
with join
Key: CARBONDATA-3452
URL: https://issues.apache.org/jira/browse/CARBONDATA-3452
Project: CarbonData
Issue Type: Bug
Reporter: Ajantha Bhat
h1. select query failure when substring on dictionary column with join
"select a.ch from (select substring(s1,1,2) as ch from t1) a join t2 h on (a.ch
= h.t2)"
problem: select query failure when substring on dictionary column with join.
cause: when dictionary include is present, data type is updated to int from
string in plan attribute. so substring was unresolved on int column. Join
operation try to reference this attribute which is unresolved.
solution: skip updating datatype if dictionary is included in the plan
