Cannot put more than 1000 elements in a InExpression ---------------------------------------------------- Key: HHH-1123 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1123 Project: Hibernate3 Type: Bug

Components: core Versions: 3.1 rc2, 3.2.0.alpha1 Environment: Oracle 9i Reporter: Alexis Seigneurin Attachments: patch.txt Original Estimate: 1 hour Remaining: 1 hour The number of elements that we can put in a "in" expression is limited to a certain amount (1000 for Oracle, for instance). When creating a criteria query, the org.hibernate.criterion.InExpression class should split the expression into several smaller ones. Attached is a patch which splits the expression by slices of 500 elements. For example, if we have 1001 elements to put in the "in" expression, the result would be : (entity.field in (?, ?, ?...) or entity.field in (?, ?, ?...) or entity.field in (?)) The surrounding parantheses are useful to avoid problems with other conditions (a "and" condition taking over the one of the "or" conditions).
