[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.

[JBoss JIRA] Created: (TEIID-1593) Creating a temp table gets error that Cannot create temporary table "dddd". A table with the same name already exists.

by Paul Nittel (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

[JBoss JIRA] Created: (TEIID-1612) Tried a custom log appended, but the LoggingEvent.getMessage() returns org.teiid.logging.LogMessage and not org.teiid.logging.CommandLogMessage

by Van Halbert (JIRA)

Tried a custom log appended, but the LoggingEvent.getMessage() returns org.teiid.logging.LogMessage and not org.teiid.logging.CommandLogMessage ----------------------------------------------------------------------------------------------------------------------------------------------- Key: TEIID-1612 URL: https://issues.jboss.org/browse/TEIID-1612 Project: Teiid Issue Type: Bug Components: Server Affects Versions: 7.1.1 Reporter: Van Halbert Assignee: Steven Hawkins Tried to create a custom logger, following what the doc says: ------ If you want to build a custom appender for command logging that will have access to log4j "LoggingEvents" to the "COMMAND_LOG" context, it will have a message that is an instance of org.teiid.logging.CommandLogMessage defined in the teiid-api-7.4.jar use these class in your development. ------- but the actual object type from event.getMessage() is: LOGGING EVENT MSG TYPE: org.teiid.logging.LogMessage (this is a sysout from the custom appender) And there, don't have access to the similar methods provided n CommandLogMessage.

[JBoss JIRA] Created: (TEIID-1585) Make payload available in ExecutionFactory.getConnection

by Mark Addleman (JIRA)

Make payload available in ExecutionFactory.getConnection -------------------------------------------------------- Key: TEIID-1585 URL: https://issues.jboss.org/browse/TEIID-1585 Project: Teiid Issue Type: Feature Request Components: Connector API Affects Versions: 7.3 Reporter: Mark Addleman Assignee: Steven Hawkins We require user-specific connections to our backend datasources. We pass user credentials to the translators using the payload but the payload is not available in the getConnection(Factory f) method. I propose adding public getConnection(Factory f, Serializable payload) method in ExecutionFactory whose default implementation is to call getConnection(Factory f). -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (TEIID-1640) QueryTimeout connection parameter does not cancel long-running queries

by Paul Nittel (JIRA)

QueryTimeout connection parameter does not cancel long-running queries ---------------------------------------------------------------------- Key: TEIID-1640 URL: https://issues.jboss.org/browse/TEIID-1640 Project: Teiid Issue Type: Bug Components: JDBC Driver Affects Versions: 7.4 Environment: Fedora 14 (server & client), Teiid 7.4 Final Reporter: Paul Nittel Assignee: Steven Hawkins Testing XML files as data sources involves running queries which can take a long time (minutes). I defined my connection URL (in SQuirreL) as jdbc:teiid:VDB@mm://localhost:31000;QueryTimeout=1 The next query I executed processed for over 4 seconds, but there was no evidence of an attempt to cancel the query. I've got a series of XML files you can use to test this, if you want. They're too big to attach (even when zipped). -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (TEIID-1678) Order by may be applied incorrectly with pushed aggregate

by Steven Hawkins (JIRA)

Order by may be applied incorrectly with pushed aggregate --------------------------------------------------------- Key: TEIID-1678 URL: https://issues.jboss.org/browse/TEIID-1678 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.1 Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 7.4.1, 7.5 If a decomposed grouping is not pushed below the accessnode, then the merge join ordering may be pushed below it - which will destroy the ordering. The order by should be above the grouping and then should be combined with the grouping during plan sorts. -- This message is automatically generated by JIRA.
