[JBoss JIRA] Created: (TEIID-1689) Load internal mateirlized view cached contents when node joins the cluster

by Ramesh Reddy (JIRA)

Load internal mateirlized view cached contents when node joins the cluster -------------------------------------------------------------------------- Key: TEIID-1689 URL: https://issues.jboss.org/browse/TEIID-1689 Project: Teiid Issue Type: Feature Request Components: Server Affects Versions: 7.4.1 Reporter: Ramesh Reddy Assignee: Ramesh Reddy When IMV loaded at Node 1, and the contents of the that IMV will be loaded at Node 2 only when the query is issued against it. Then user incurs the wait time to load the contents from Node 1. If in the situation if Node 1, went down before the query to Node 2, in that case node 2 has to fetch from the source and cached contents will be lost. This can be avoided by hot loading the all the cached contents at the start of the node from other nodes. -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (TEIID-1691) Improve xml staging table planning

by Steven Hawkins (JIRA)

Improve xml staging table planning ---------------------------------- Key: TEIID-1691 URL: https://issues.jboss.org/browse/TEIID-1691 Project: Teiid Issue Type: Enhancement Components: Query Engine Affects Versions: 7.4.1 Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 7.4.1, 7.5 Staging table planning should allow for dependent join loads using the parent values. This should be done regardless of whether the parent is also staged. For large staged tables it would also be good to index on the join columns. -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (TEIID-1727) Undeploying a vdb inappropriately updates all vdbs

by Steven Hawkins (JIRA)

Undeploying a vdb inappropriately updates all vdbs -------------------------------------------------- Key: TEIID-1727 URL: https://issues.jboss.org/browse/TEIID-1727 Project: Teiid Issue Type: Bug Components: Server Affects Versions: 7.1 Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 7.4.1, 7.6 When a vdb is undeployed the VDBRepository.removeVDB logic unconditionally calls removeChild on all vdbs in the repository. This causes each to build a new metadata state resulting in duplicate mat views and inconsistent metadata updates. -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (TEIID-1681) Limit not working as expected

by Gaurav Chaudhary (JIRA)

Limit not working as expected ----------------------------- Key: TEIID-1681 URL: https://issues.jboss.org/browse/TEIID-1681 Project: Teiid Issue Type: Bug Components: JDBC Driver Affects Versions: 7.3 Reporter: Gaurav Chaudhary Assignee: Steven Hawkins select CHORUS_B."ID", CHORUS_B."ACCESS_MODE", CHORUS_B."USER_ID", CHORUS_B."CREATED_ON", CHORUS_B."NOTE",'chorusdata.note' as "__objecttype__" from (select * from chorus_notes.RETRIEVE_NOTES where OBJECT_PKEY = xmlserialize(xmlelement("demodata.rule", XMLATTRIBUTES(cast('name 1' as String) as "name",cast('sysid 0' as String) as "system",cast('user 1000' as String) as "user")) as String)) as CHORUS_B LIMIT 50 This query is not returning correct results unless we remove Limit from this. If we include Limit over here, it interchanges the columns and returning incorrect data. -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (TEIID-1465) Join between char and varchar

by Claudio Venturini (JIRA)

Join between char and varchar ----------------------------- Key: TEIID-1465 URL: https://issues.jboss.org/browse/TEIID-1465 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.3 Environment: Teiid 7.3 deployed on Jboss AS 5.1.0 GA running on Ubuntu Server 10.04 LTS, MySQL 5.1.51 running on the same machine as JBoss, SQL Server 2000 Standard SP4 running on Windows Server 2003 Reporter: Claudio Venturini Assignee: Steven Hawkins Joins between char and varchar fields fail. Suppose to have a table T1 with a field A, declared as char(10), and a table T2 with a field B, declared as varchar(10). Suppose that the two tables have the following data. *T1*: ||A|| |ML0001| *T2*: ||B|| |ML0001| When performing a INNER JOIN with the condition {{T1.A = T2.B}} the result set is empty, even if the two record match correctly. This happens when the two base tables refer to two different sources, because if they are in the same source Teiid pushes the join to the source, which computes it correctly. I think the problem is in the comparison of the two strings. I have the table T1 in SQL Server 2000, and the table T2 in MySQL 5.1. If one asks SQL Server to convert the string to bytes, the result is {{0x4D4C3030303120202020}}, because the string is filled with (invisible) blanks in order to reach the limit of 10 characters. Note that if one asks for the length of that string, SQL Server states (correctly) that it is 6 characters. The string in MySQL is a VARCHAR(10), so its conversion to binary is {{0x4D4C30303031}}. I think that Teiid compares the two binary strings in their entire length. That comparison fails, and no match is found. The problem remains even if the table T1 is placed in MySQL, and T2 in SQL Server (the opposite situation). I also verified that the problem exists either when querying the source models or view models built over them. *Workaround:* A workaround exists but it is too complex (IMHO). I haven't tested it with many records, but I think it will slow down performances considerably. It consists in casting the string from char to varchar, and then trimming it (with RTRIM() and LTRIM() because SQL Server doesn't support TRIM()). So the join condition is: {noformat} RTRIM(LTRIM(CAST(T1.A AS VARCHAR))) = T2.B {noformat} -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (TEIID-1613) Cannot define an implicit temp table with columns and a query value expression

by Steven Hawkins (JIRA)

Cannot define an implicit temp table with columns and a query value expression ------------------------------------------------------------------------------ Key: TEIID-1613 URL: https://issues.jboss.org/browse/TEIID-1613 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.4 Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 7.4.1 I believe this may have been a regression from TEIID-1177. "insert into #x select 1 as y" works, but "insert into #x (y) select 1 as y" does not. -- This message is automatically generated by JIRA.

Creating a temp table gets error that Cannot create temporary table "dddd". A table with the same name already exists. ---------------------------------------------------------------------------------------------------------------------- Key: TEIID-1593 URL: https://issues.jboss.org/browse/TEIID-1593 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.4 Reporter: Paul Nittel Assignee: Steven Hawkins Logging into a VDB using SQuirreL, I entered: create local temporary table dddd (id string, name string) What I received was: Cannot create temporary table "dddd". A table with the same name already exists. There appears to be no way to create a temporary table, using this method. SELECT * INTO #temp from ... does work, however. -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira
