[JBoss JIRA] Created: (TEIID-1508) Dependent join planning problem

by Steven Hawkins (JIRA)

Dependent join planning problem ------------------------------- Key: TEIID-1508 URL: https://issues.jboss.org/browse/TEIID-1508 Project: Teiid Issue Type: Quality Risk Components: Query Engine Affects Versions: 7.4 Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 7.4 Without a dependent join hint a composite cross source dependent join will not plan correctly unless the independent side can be pushed as a single query. The root of the issue is that join planning involving more than 1 independent table does not consider the effect of potential dependent joins early enough. The workaround is to use a dependent join hint or set the cardinality of the independent tables small enough to trigger the proper dependent join. -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (TEIID-1458) Wrong count(*) result when joining data from two models

by Claudio Venturini (JIRA)

Wrong count(*) result when joining data from two models ------------------------------------------------------- Key: TEIID-1458 URL: https://issues.jboss.org/browse/TEIID-1458 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.3, 7.2 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 maching as JBoss, SQL Server 2000 Standard SP4 running on Windows Server 2003 Reporter: Claudio Venturini Assignee: Steven Hawkins count(\*) gets a wrong result when is performed in a query which joins two tables coming from two different models. The first (named "sqlsrv") is a source model for a table stored in SQL Server 2000. The second (named "mysql") is a source model for a table stored in MySQl 5.1. The query performs an inner join on the column "product_id", which is shared by the two tables. All records match correctly, so there should be no difference in using an inner join instead of other join types. The query is the following: {noformat} SELECT invoice, invoice_date, code, sum(quantity) AS s, avg(price) AS av, count(*) AS dim FROM sqlsrv.test2.dbo.sales SL INNER JOIN mysql.test.product_code PC ON SL.product_id = PC.product_id GROUP BY invoice_date, invoice, code ORDER BY invoice_date ASC, invoice ASC, code ASC {noformat} The result of count(\*) is 1 for all records, while for some of them it should be 2, as there are duplicate records in the sales table, which are grouped by the GROUP BY clause. Note that the problem exists only with the inner join. Left, right and outer joins work well, even if the set of records that they produce is the same as that produced by the inner join. I noticed the problem in Teiid 7.2. Tonight I upgraded to 7.3, but the problem is still there. If the data are all in the same DB, the query works as expected. It is not significant in which of the two DB each table resides. I think it is neither a problem of the SQL Server connector, nor of the MySQL connector. The data are the following: *product_code*: ||code||category||product_id|| |1|1|125| |2|1|127| |3|1|123| |4|1|121| |5|1|126| |6|1|124| |7|1|122| *sales*: ||invoice||invoice_date||product_id||quantity||price|| |009831|2009-08-15 00:00:00|125|350|1.070261| |009831|2009-08-15 00:00:00|124|960|1.070261| |009843|2009-08-15 00:00:00|121|648|1.515264| |009843|2009-08-15 00:00:00|126|145|2.763902| |009843|2009-08-15 00:00:00|126|25|2.407148| |009855|2009-08-15 00:00:00|122|768|1.122835| |009855|2009-08-15 00:00:00|123|540|1.158511| |009855|2009-08-15 00:00:00|125|480|1.070261| |009857|2009-08-15 00:00:00|122|440|1.498365| |009857|2009-08-15 00:00:00|126|115|2.585525| |009866|2009-08-15 00:00:00|122|736|1.498365| |009866|2009-08-15 00:00:00|123|558|1.391339| |009866|2009-08-15 00:00:00|125|378|1.336887| |009866|2009-08-15 00:00:00|127|510|1.605391| |009866|2009-08-15 00:00:00|126|435|2.585525| |009847|2009-08-15 00:00:00|126|55|2.763902| |009847|2009-08-15 00:00:00|126|5|2.407148| |009847|2009-08-15 00:00:00|121|240|1.872018| The result of the above query is: ||invoice||invoice_date||code||s||av||dim|| |009831|2009-08-15 00:00:00|1|350.0|1.070261|1| |009831|2009-08-15 00:00:00|6|960.0|1.070261|1| |009843|2009-08-15 00:00:00|4|648.0|1.515264|1| |009843|2009-08-15 00:00:00|5|170.0|2.585525|1| |009847|2009-08-15 00:00:00|4|240.0|1.872018|1| |009847|2009-08-15 00:00:00|5|60.0|2.585525|1| |009855|2009-08-15 00:00:00|1|480.0|1.070261|1| |009855|2009-08-15 00:00:00|3|540.0|1.158511|1| |009855|2009-08-15 00:00:00|7|768.0|1.122835|1| |009857|2009-08-15 00:00:00|5|115.0|2.585525|1| |009857|2009-08-15 00:00:00|7|440.0|1.498365|1| |009866|2009-08-15 00:00:00|1|378.0|1.336887|1| |009866|2009-08-15 00:00:00|2|510.0|1.605391|1| |009866|2009-08-15 00:00:00|3|558.0|1.391339|1| |009866|2009-08-15 00:00:00|5|435.0|2.585525|1| |009866|2009-08-15 00:00:00|7|736.0|1.498365|1| As you can see, count(\*) (the "dim" column) always returns 1, even if it should return 2 for the product with id 126 in invoices 009843 and 009847.

[JBoss JIRA] Created: (TEIID-1502) ODBC (and admin) scalability limited by maxWorker cap

by Steven Hawkins (JIRA)

ODBC (and admin) scalability limited by maxWorker cap ----------------------------------------------------- Key: TEIID-1502 URL: https://issues.jboss.org/browse/TEIID-1502 Project: Teiid Issue Type: Bug Components: Server Affects Versions: 7.1 Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Critical Fix For: 7.4 We are capping the max workers in an attempt to prevent excessive thread use, but this prevents the blocking operations of ODBC/admin to scale well. The long term fix is to make ODBC/admin operations non-blocking wrt the IO. -- This message is automatically generated by JIRA.

Teiid's ODBC interaction with PostgreSQL-ODBC fails when column lengths exceed 64K as PostgreSQL stores these values as a short ------------------------------------------------------------------------------------------------------------------------------- Key: TEIID-1480 URL: https://issues.jboss.org/browse/TEIID-1480 Project: Teiid Issue Type: Bug Reporter: Paul Nittel Assignee: Steven Hawkins I imported the AdventureWorks2000 database from SQL Server.

[JBoss JIRA] Created: (TEIID-1487) CLONE - Add implicit conversion of NULL to correct datatype in transformation validator

by Steven Hawkins (JIRA)

CLONE - Add implicit conversion of NULL to correct datatype in transformation validator --------------------------------------------------------------------------------------- Key: TEIID-1487 URL: https://issues.jboss.org/browse/TEIID-1487 Project: Teiid Issue Type: Feature Request Components: Query Engine Affects Versions: 6.0.0 Reporter: Marc Shirley When using NULL value as a column (ie, NULL as columnName), it is only implicitly converted to a string. When trying to use the NULL as a column of type date, integer, float, etc., the validator throws a warning that the transformation is not valid. If you wrap the NULL in a convert to the correct column datatype (ie, "convert(NULL,date)"), the transformation can be validated successfully. -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (TEIID-1383) Partial Results processing fails too easily when a source is unavailable

by Paul Nittel (JIRA)

Partial Results processing fails too easily when a source is unavailable ------------------------------------------------------------------------ Key: TEIID-1383 URL: https://jira.jboss.org/browse/TEIID-1383 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.1.1 Environment: Fedora 12, SOA-P ER4 Reporter: Paul Nittel Assignee: Steven Hawkins I'm updating the MMx partial results test to work with Teiid and ran into this problem while testing that. To mimic an unavailable data source, I munged the server name in the data source definition (-ds) file. Using SQuirreL, I first "set partialResultsMode true" and then query a unioned table: SELECT * FROM PartialVM.MyUnionTable order by INTKEY. I'm getting back an exception about the bad connection, but no apparent attempt to continue the query without that source is made. Steve Hawkins suspects, "it's testing partial results at too low of a level". Artifacts will be attached. -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
