Query with an IN Clause object that holds an Enum is failing with ORA-01722: invalid number (Criteria) OR ORA-17041: Missing IN or OUT parameter at index (HQL) --------------------------------------------------------------------------------------------------------------------------------------------------------------- Key: ANN-684 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-684 Project: Hibernate Annotations Issue Type: Bug Components: search Affects Versions: 3.2.0.ga Environment: Hibernate 3.2.0 (cr4) Oracle Annotations Reporter: Li Ho I am trying to do a query with an IN clause. The object I am passing into the IN clause contains an Enum. I'm not 100% sure, but I think the Enum is causing the problem based on the resulting error message. When I use the Criteria API, I get the following error: ORA-01722: invalid number When I use the equivalent HQL, I get: ORA-17041: Missing IN or OUT parameter at index Here is some code (using criteria) that produces the error List<AccountKey> accountKeys; // AccountKey contains some Strings and an Enum ... List results = session.createCriteria(MyObject.class). add(Expression.in("key.account.key", accountKeys)). list(); The debug SQL looks right... and when I manually try it by replacing the ? params with valid values, it works! So, it seems like there's a problem with the passing of the query parameter values. I am currently working around this issue by bypassing the object comparison. I extract the variables I want to compare and force it to do a direct String comparison on those elements. -- 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
