[JBoss JIRA] Created: (TEIID-799) String to boolean conversion should throw an exception

by Steven Hawkins (JIRA)

String to boolean conversion should throw an exception ------------------------------------------------------ Key: TEIID-799 URL: https://jira.jboss.org/jira/browse/TEIID-799 Project: Teiid Issue Type: Quality Risk Components: Query Engine Affects Versions: 6.0.0 Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Minor Fix For: 6.2.0 To be more inline with the sql spec. The string to boolean conversion should throw an exception rather than using the default Boolean.valueOf method when the input string is not one of 0,1,TRUE,FALSE,UNKNOWN. As it stands the method is inappropriately marked as non-narrowing and maps any non-true value to false. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (TEIID-848) Insert with out of order variables and query expression is incorrect

by Steven Hawkins (JIRA)

Insert with out of order variables and query expression is incorrect -------------------------------------------------------------------- Key: TEIID-848 URL: https://jira.jboss.org/jira/browse/TEIID-848 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 6.0.0 Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 6.3.0 For example: create local temporary table x (e1 string, e2 integer); insert into x (e2, e1) select e2, e1 from pm1.g1; would fail because we are simply rewriting to select e2, e1 into x from pm1.g1. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (TEIID-748) QueryRewriter null handling

by Steven Hawkins (JIRA)

QueryRewriter null handling --------------------------- Key: TEIID-748 URL: https://jira.jboss.org/jira/browse/TEIID-748 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 6.0.0 Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Minor Fix For: 6.2.0 The rewriter changes several criteria fragments into true/false criteria ignoring the affect of nulls. i.e. pm1.g1.e1 like '%' is not same as 1 = 1 since null e1 values should not be allowed to pass. This is not a regression, but has been a problem since the switch to three valued logic. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (TEIID-816) XML-Relational File connector throws NPE.

by John Doyle (JIRA)

XML-Relational File connector throws NPE. ----------------------------------------- Key: TEIID-816 URL: https://jira.jboss.org/jira/browse/TEIID-816 Project: Teiid Issue Type: Bug Components: XML Connector Affects Versions: 6.2.0 Reporter: John Doyle Assignee: John Doyle Fix For: 6.2.0 The XML-Relational File connector is throwing an NPE on start up because the caching Boolean is null. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (TEIID-605) Push down query results different than MetaMatrix query results without push down - Oracle 11

by Warren Gibson (JIRA)

Push down query results different than MetaMatrix query results without push down - Oracle 11 ---------------------------------------------------------------------------------------------- Key: TEIID-605 URL: https://jira.jboss.org/jira/browse/TEIID-605 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 6.0.0 Environment: Running Teiid Server on Windows CTC Query testing client on Windows Reporter: Warren Gibson Assignee: Steven Hawkins This may not be a bug but may just be a decision point to determine if MetaMatrix should guarantee the same query results as if the query was pushed down to the source. In some cases different results can be expected from different DBMS sources. 1. Running Teiid Server with Console Extension Capability Class set to default (blank). 2. Run queries against Oracle 11 source. 3. Results show many examples where "nulls" are being handled differently in a push down ORDER BY situation than what our expected results reflect. 4. Basically in the Oracle 11 situation the "nulls" are showing up in the results just opposite from what MetaMatrix does. In other words in the following query "Select BQT1.SmallA.IntNum From BQT1.SmallA ORDER BY BQT1.SmallA.IntNum DESC" push down results shows "nulls" at the beginning of results whereas without push down MetaMatrix will show the "nulls" at the end of the results. 5. See attached results from this query. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

by John Doyle (JIRA)

XML-Relational connector is not handling = criteria. ---------------------------------------------------- Key: TEIID-817 URL: https://jira.jboss.org/jira/browse/TEIID-817 Project: Teiid Issue Type: Bug Affects Versions: 6.1.0, 6.2.0 Reporter: John Doyle Assignee: John Doyle Fix For: 6.2.0 All XML-R connectors are ignoring = criteria passed in queries. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (TEIID-486) MOD() scalar function should be supported by DB2 Connector

by Larry O'Leary (JIRA)

MOD() scalar function should be supported by DB2 Connector ---------------------------------------------------------- Key: TEIID-486 URL: https://jira.jboss.org/jira/browse/TEIID-486 Project: Teiid Issue Type: Feature Request Components: JDBC Connector Affects Versions: 6.0.0, 6.1.0 Reporter: Larry O'Leary Assignee: Steven Hawkins An issue was logged in where a function that resulted in the use of the mod() scalar function would result in a different query plan causing the queries criteria not to be pushed-down to the source. It appears the cause of the misbehaved query plan was the DB2 connector not supporting the MOD() scalar function. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (TEIID-852) Oracle timestamp to time conversion null handling

by Steven Hawkins (JIRA)

Oracle timestamp to time conversion null handling ------------------------------------------------- Key: TEIID-852 URL: https://jira.jboss.org/jira/browse/TEIID-852 Project: Teiid Issue Type: Bug Components: JDBC Connector Affects Versions: 6.2.0 Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 6.3.0 Null values are converted to the default time of 00:00:00, this is due to oracle's concat function that returns an empty string with a null input. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (TEIID-813) Perform bound checking on narrowing numeric conversions

by Steven Hawkins (JIRA)

Perform bound checking on narrowing numeric conversions ------------------------------------------------------- Key: TEIID-813 URL: https://jira.jboss.org/jira/browse/TEIID-813 Project: Teiid Issue Type: Quality Risk Components: Query Engine Affects Versions: 6.2.0 Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 6.2.0 In order to be more compatible with source type systems we should range check numeric conversions. This will also allow for such conversion to not be marked as narrowing for the purposes of rewrite (but they will still not be implicit due to the possible exception). -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (TEIID-794) Simplify functionmodifier

by Steven Hawkins (JIRA)

Simplify functionmodifier ------------------------- Key: TEIID-794 URL: https://jira.jboss.org/jira/browse/TEIID-794 Project: Teiid Issue Type: Quality Risk Components: JDBC Connector Affects Versions: 6.0.0 Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Minor Fix For: 6.3.0 It is no longer necessary to have both a modify and a translate method, since translate can be used to return the function itself. Making this simplification prevents confusing problems such as changing a function name in modify and then having translate not be applied. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
