[JBoss JIRA] (TEIID-4422) Impala Translator - add pushdown support for concat and concat_ws functions

by Steven Hawkins (JIRA)

[ https://issues.jboss.org/browse/TEIID-4422?page=com.atlassian.jira.plugin... ] Steven Hawkins commented on TEIID-4422: --------------------------------------- Our concat system function does currently push down to impala, but does not expect varargs - are you requesting that the Teiid system function supports varargs? Similarly are you requesting that a concat_ws system function be added? Or is it sufficient to just add concat_ws to the pushdown functions exposed by the translator? For group_concat, we can map that to the pushdown of the Teiid string_agg function. > Impala Translator - add pushdown support for concat and concat_ws functions > --------------------------------------------------------------------------- > > Key: TEIID-4422 > URL: https://issues.jboss.org/browse/TEIID-4422 > Project: Teiid > Issue Type: Feature Request > Components: JDBC Connector > Affects Versions: 9.0.2 > Reporter: Don Krapohl > Assignee: Steven Hawkins > > As a consumer I need the concat and concat_ws function definitions with matching signatures in line with http://www.cloudera.com/documentation/archive/impala/2-x/2-0-x/topics/imp... > concat: > concat(string a, string b...) > Purpose: Returns a single string representing all the argument values joined together. > Return type: string > Usage notes: concat() and concat_ws() are appropriate for concatenating the values of multiple columns within the same row, while group_concat() joins together values from different rows. > concat_ws: > concat_ws(string sep, string a, string b...) > Purpose: Returns a single string representing the second and following argument values joined together, delimited by a specified separator. > Return type: string > Usage notes: concat() and concat_ws() are appropriate for concatenating the values of multiple columns within the same row, while group_concat() joins together values from different rows. -- This message was sent by Atlassian JIRA (v6.4.11#64026)

by Mark Tawk (JIRA)

[ https://issues.jboss.org/browse/TEIID-4021?page=com.atlassian.jira.plugin... ] Mark Tawk commented on TEIID-4021: ---------------------------------- The workaround you suggested is better then assigning the database version property on the executionfactory to the lowest version.

And the execution is taking too much time. -- This message was sent by Atlassian JIRA (v6.4.11#64026)

[JBoss JIRA] (TEIID-4421) Teiid Translator per source/version

by Mark Tawk (JIRA)

Mark Tawk created TEIID-4421: -------------------------------- Summary: Teiid Translator per source/version Key: TEIID-4421 URL: https://issues.jboss.org/browse/TEIID-4421 Project: Teiid Issue Type: Feature Request Reporter: Mark Tawk Assignee: Steven Hawkins Teiid actually uses a single translator to connect to a single source/version. However in the case of translators that auto-configure to the given version it is expected to manage creating new instances when necessary. Case reproduced when connecting to 2 DBs, one on SQL Server 2012 and another on SQL Server 2008. The pagination SQL translation of SQL Server 2012 does not work on 2008. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
