[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-2697) Can't use := for variable assignment within a SQL-Statement

Can't use := for variable assignment within a SQL-Statement ----------------------------------------------------------- Key: HHH-2697 URL: https://hibernate.onjira.com/browse/HHH-2697 Project: Hibernate ORM Issue Type: Bug Affects Versions: 3.2.4.sp1 Environment: MySQL Datasource, Hibernate 3.2.4.sp1 Reporter: Benjamin Gniza Assignee: Strong Liu Priority: Minor Fix For: 4.1.x Attachments: allowvariableassignment.patch i found a kind of bug in org.hibernate.engine.query.ParameterParser.java: I have an exotic mysql-statement where I want to use mysql variables. VERY SIMPLE example: SET @pos=0; SELECT @pos:=@pos+1 FROM TABLE; Steps to reproduce: Session s = sessionFactory.openSession(); s.createSQLQuery("SET @pos=0").executeUpdate(); SQLQuery qry = s.createSQLQuery("select @pos:=@pos from SomeTable"); List lst = qry.list(); Exception: org.hibernate.QueryException: Space is not allowed after parameter prefix ':' 'SELECT @pos:=@pos+1 FROM TABLE' at org.hibernate.engine.query.ParameterParser.parse(ParameterParser.java:68) ... ... Suggested fix: ParameterParser Lines 62 to 73: if (c == ':' && (indx + 1 >= stringLength || sqlString.charAt(indx + 1) != '=')) { // named parameter int right = StringHelper.firstIndexOfChar( sqlString, ParserHelper.HQL_SEPARATORS, indx + 1 ); int chopLocation = right < 0 ? sqlString.length() : right; String param = sqlString.substring( indx + 1, chopLocation ); if ( StringHelper.isEmpty( param ) ) { throw new QueryException("Space is not allowed after parameter prefix ':' '" + sqlString + "'"); } recognizer.namedParameter( param, indx ); indx = chopLocation - 1; }
