SybaseASE15Dialect getMaxAliasLength() cause SQL exception ---------------------------------------------------------- Key: HHH-5909 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5909 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.6.0, 3.6.1 Environment: Sybase ASE 15.5 with Sybase JDBC 3 (jconn3.jar) Hibernate 3.6.0 final JDK 1.6.0_23 Reporter: Yang Li Assignee: Strong Liu Priority: Critical Original Estimate: 0.5h Remaining Estimate: 0.5h After upgrade Hibernate from 3.2.0 to 3.6.0, I got following exception with following SQL (converted from HQL): select defaultwdo1_.displayDescriptionTemplate as displayDescriptionTemplate30_1_ from WJob wjob0_, WDocDist defaultwdo1_ Caused by: com.sybase.jdbc3.jdbc.SybSQLException: The identifier that starts with 'displayDescriptionTemplate30_1' is too long. Maximum length is 30. at com.sybase.jdbc3.tds.Tds.a(Unknown Source) at com.sybase.jdbc3.tds.Tds.nextResult(Unknown Source) at com.sybase.jdbc3.jdbc.ResultGetter.nextResult(Unknown Source) at com.sybase.jdbc3.jdbc.SybStatement.nextResult(Unknown Source) at com.sybase.jdbc3.jdbc.SybStatement.nextResult(Unknown Source) at com.sybase.jdbc3.jdbc.SybStatement.queryLoop(Unknown Source) at com.sybase.jdbc3.jdbc.SybStatement.executeQuery(Unknown Source) at com.sybase.jdbc3.jdbc.SybPreparedStatement.executeQuery(Unknown Source) at org.hibernate.jdbc.AbstractBatcher.getResultSet(AbstractBatcher.java:208) at org.hibernate.loader.Loader.getResultSet(Loader.java:1953) The same SQL can be executed in native Sybase ISQL environment without any error. The workaround using Sybase11Dilect or modify getMaxAliasLength() inside SybaseASE15Dialect to return a smaller number(e.g. 20)
