Oleksandr Diachenko updated HAWQ-1103: -------------------------------------- Fix Version/s: (was: backlog) 2.0.1.0-incubating > Send constant datatype and length in filter to PXF > -------------------------------------------------- > > Key: HAWQ-1103 > URL: https://issues.apache.org/jira/browse/HAWQ-1103 > Project: Apache HAWQ > Issue Type: Improvement > Components: PXF > Reporter: Oleksandr Diachenko > Assignee: Oleksandr Diachenko > Fix For: 2.0.1.0-incubating > > > As for now HAWQ sends filter string without datatypes and length: > a<column index>c<constant value>o<operation code>... > Idea is to send filter in following format: > a<column index>c<scalar constant datatype oid>s<number of characters to > read>d<actual data>o<operation code> > or > c<scalar constant datatype oid>s<number of characters to read>d<actual > data>a<column index>o<operation code> > This approach takes care of escaping symbols. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
