[JBoss JIRA] (TEIID-2640) Field with NULL value is replaced by a non-NULL field during modify

by Sai Gujja (JIRA)

[ https://issues.jboss.org/browse/TEIID-2640?page=com.atlassian.jira.plugin... ] Sai Gujja commented on TEIID-2640: ---------------------------------- Here is the Discussion I posted. https://community.jboss.org/message/834497#834497 > Field with NULL value is replaced by a non-NULL field during modify > ------------------------------------------------------------------- > > Key: TEIID-2640 > URL: https://issues.jboss.org/browse/TEIID-2640 > Project: Teiid > Issue Type: Bug > Affects Versions: 8.4 > Environment: Java application running on Mainframe > Reporter: Sai Gujja > Assignee: Steven Hawkins > Labels: Date, NULL, VARCHAR > > We have a java application running on Mainframe that uses TEIID. We used the Database Explorer plugin as well to reproduce the error. > We were trying to update two fields, of which one had a value that we were trying to remove and adding a value to the other one. Let's say the fields are CONSID and EXPDATE. CONSID is a vachar that accepts a one letter word, such as 's','a' etc. EXPDATE is a date field. CONSID had a value in it already before we started our modify function. So our modification included removing the value for CONSID(making it NULL) and adding a date for EXPDATE. So the update Query we sent looked like: > Execute UPDATE tssadmingrp=acids,host=de30_de29,o=cai,c=us SET EXPDATE = {d '2013-12-12'}, CONSID = NULL WHERE acf2admingrp=lids,host=xe42_cia,o=ca,c=us?SUBTREE_SCOPE.DN = '"tssacid=TSSACID,tssadmingrp=acids,host=de30_de29,o=cai,c=us"' > We use a LDAP translator to send these modify queries to LDAP server. The update query seemed right, but the query that is sent over to LDAP was wrong. The values that were being sent to LDAP were same for CONSID and EXPDATE (both of them had date values in them). Since LDAP doesn't recognize date value in CONSID, it failed. > This is where we don't understand what is going wrong between the update query being generated and that is sent to LDAP. Can you please advice us? > Thank you. -- This message is automatically generated by JIRA.

[JBoss JIRA] (TEIID-2469) Load Materialised Views

[JBoss JIRA] (TEIID-2249) Enable the use of temporary tables for those data sources that support them instead of IN criteria for EDS

by Steven Hawkins (JIRA)

[ https://issues.jboss.org/browse/TEIID-2249?page=com.atlassian.jira.plugin... ] Steven Hawkins resolved TEIID-2249. ----------------------------------- Resolution: Done Marking the parent issue as resolved. Initial support for both built-in key set and full join push-down has been added. Additional work may be needed around hinting or to allow the optimizer to better choose when to do the full pushdown. > Enable the use of temporary tables for those data sources that support them instead of IN criteria for EDS > ---------------------------------------------------------------------------------------------------------- > > Key: TEIID-2249 > URL: https://issues.jboss.org/browse/TEIID-2249 > Project: Teiid > Issue Type: Feature Request > Components: Query Engine > Reporter: Debbie Steigner > Assignee: Steven Hawkins > Fix For: 8.5 > > > Our proposal is to allow for the more efficient use of large ad-hoc result-sets by rather than creating a long 'IN' list, inserting them in to a temporary table - for example a # table in Sybase and SQL Server - and then generating an SQL join to that instead. > One of the difference to materialized views (or at least my understanding), is that this work happens at a data-source rather than within the Teiid server. -- This message is automatically generated by JIRA.

[JBoss JIRA] (TEIID-2263) makedep makenotdep hints should allow for more complicated scenarios

by Steven Hawkins (JIRA)

This is not generally a good idea. We should allow for something akin to oracle global table syntax (view.)*table to drill down more specifically. Ideally we'd also account for subqueries and set operations as well. -- This message is automatically generated by JIRA.

[JBoss JIRA] (TEIID-2639) Internally generated and user submitted anonymous blocks can't access temp tables from the surrounding scope

[JBoss JIRA] (TEIID-2584) Add management features to materialization

by SBS JIRA Integration (JIRA)

The internal is managed completely by the Teiid query engine along with the infinispan cache. > External materialization is completely unmanaged and left out to the user to manage it externally. This goals for this feature are unify the materialization logic for internal and external, such that both are managed similarly irrespective of the type of materialization chosen. -- This message is automatically generated by JIRA.

[JBoss JIRA] (TEIID-2641) improve transaction handling in procedures

by Steven Hawkins (JIRA)

[ https://issues.jboss.org/browse/TEIID-2641?page=com.atlassian.jira.plugin... ] Steven Hawkins resolved TEIID-2641. ----------------------------------- Resolution: Done Addressed several issues: 1. we are not properly marking hold vs no_hold on procedures that do not return result sets. A returnable statement will be returned as the result inadvertently if executed in the procedure. 2. loop cursors are not properly isolated with exception handling - if an exception is caught from a loop, the cursor will still exist afterwards and the use of a cursor with the same name after that will be erroneous. 3. error statements are not properly resolved as they are inadvertently being resolved as if they were a continuation of the block statements - they instead need to resolve against the parent scope. 4. on an exception the block is popped but not clearly handled. We now will pop it as a failure and if there is a higher level transaction running it will be marked as rollback only. This prevents the commit of partial atomic blocks. After some investigation it does seem like proper behavior to allow variable assignments and the implicit cursor value to be non-transaction - that is as soon as the assignment is made it will be unaffected by rollback. I'll update the docs to make this explicit. > improve transaction handling in procedures > ------------------------------------------ > > Key: TEIID-2641 > URL: https://issues.jboss.org/browse/TEIID-2641 > Project: Teiid > Issue Type: Bug > Components: Query Engine > Affects Versions: 7.6 > Reporter: Steven Hawkins > Assignee: Steven Hawkins > Priority: Critical > Fix For: 8.5 > > > Atomic blocks do not have well-defined handling w.r.t. variable assignments and the implicit return cursor. In both cases the affects are currently non-atomic - the last assignment/cursor is effective even. > Also exception handling in an atomic block must result in an exception being thrown to guarantee the entire block atomicity. -- This message is automatically generated by JIRA.
