> Key: PHOENIX-6683
> URL: https://issues.apache.org/jira/browse/PHOENIX-6683
> Project: Phoenix
> Issue Type: Bug
> Components: spark-connector
> Reporter: Rajeshbabu Chintaguntla
> Assignee: Rajeshbabu Chintaguntla
> Priority: Major
>
> If there are mix of *AND* and *OR* filters in the query while converting the
> to phoenix filter from spark filters no parentheses got added to *OR* filters
> which is leading to wrong filter and finally getting wrong data.
> For example if the filter is used is below
> {code}
> where ENTITY_INSTANCE_ID = 40 and (CANCELLATION_FLAG <> 'Y' OR
> CANCELLATION_FLAG IS NULL ) and CASE_MATCH_TYPE='M'
> {code}
> which is getting converted to an expression and leading to wrong result
> because result is always giving most of the records matching
> CANCELLATION_FLAG is not 'Y'
> {code}
> NOT "CANCELLATION_FLAG" = 'Y' OR "CANCELLATION_FLAG" IS NULL AND
> "CASE_MATCH_TYPE" IS NOT NULL AND "ENTITY_INSTANCE_ID" = 40 AND
> "ENTITY_INSTANCE_ID" IS NOT NULL AND "CASE_MATCH_TYPE" = 'M'
> {code}
