String Scalar Function CONCAT and operator || in HQL not working correctly with numeric values ---------------------------------------------------------------------------------------------- Key: HHH-3627 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3627 Project: Hibernate Core Issue Type: Bug Components: query-hql Affects Versions: 3.3.1 Environment: MS SQL 2005 Reporter: Eric Belanger Priority: Minor Since HQL translate the CONCAT and || to + in SQL, numeric values get added together instead of being converted to String and concanated. Also causes problems when concatenating a numeric with a string. SELECT CONCAT(1, 2) FROM... Returns 3 instead of '12' SELECT CONCAT('TWO', 2) FROM ... java.sql.SQLException: Conversion failed when converting the varchar value 'TWO' to data type int. java.sql.SQLException: Conversion failed when converting the varchar value 'TWO' to data type int. at net.sourceforge.jtds.jdbc.SQLDiagnostic.addDiagnostic(SQLDiagnostic.java:365) at
