show_sql output should identify the Named Query associated with generated SQL output ------------------------------------------------------------------------------------ Key: HHH-3289 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3289 Project: Hibernate3 Issue Type: Improvement Components: core Affects Versions: 3.3.0 Reporter: Jim Doyle It is useful to know which named query was at cause for generated SQL traffic in output logs. Medium sized applications can realistically employ a hundred named queries and it is extremely useful to known the ID of the named query as well as see the generated SQL. This feature would very much improve the ability of DBAs to undertake performance tuning. In a typical use case, the DBA would cut and paste the generated show_sql query directly in the the vendor database Explain tool to analyze performance. After manually tuning the query in the Explain analyzer, changes to the JPQL or HQL can then be applied, deployed and tested again by looking at the generated SQL. I propose changing the show_sql output to appear as follows: 10:21:04,397 INFO [STDOUT] Hibernate [MYsessionFactoryId] [MYnamedQueryName] : select top 5 pro0_.transactionID as transact2_27_, pro0_.date as date27_, pro0_.suffix_suffixCodeID as suffix40_27_, pro0_.creationDate as creation4_27_, .... A String that identifies the Session Factory will be printed to disambiguate the originating SF that produced the SQL. This is necessary in environments where more than one session factory is present (JBoss container, multiply deployed application in Tomcat). In such cases, it *MIGHT* be possible for two different session factories to have identically named named queries, so by printing an Id for the Session Factory, there is a means of resolving this when examing the output. The Named Query identifier will only appear for Named Native or Named JPQL/HQL type queries. For ad-hoc queries, the brackets may be either empty or not present to indicate that the generated SQL verbs originate from a source other than a named query. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
