Kavinder Dhaliwal reassigned HAWQ-973: -------------------------------------- Assignee: Kavinder Dhaliwal (was: Goden Yao) > Check pi_varList in pxfheaders before setting headers > ----------------------------------------------------- > > Key: HAWQ-973 > URL: https://issues.apache.org/jira/browse/HAWQ-973 > Project: Apache HAWQ > Issue Type: Bug > Components: PXF > Reporter: Kavinder Dhaliwal > Assignee: Kavinder Dhaliwal > > {code} > add_projection_desc_httpheader > {code} > extracts the indices of columns to project from pi_varNumbers, but calculates > the length based on pi_targetList. This is similar to how ExecVariableList > handles projection. However there are cases where length(pi_targetList) >0 > and length(pi_varNumbers) == 0, so a condition on pi_varList needs to be > added before invoking add_projection_desc_httpheader as is done in > ExecProject. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
