[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-2189) Left Outer Join Conditions

Left Outer Join Conditions -------------------------- Key: HHH-2189 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2189 Project: Hibernate3 Issue Type: Bug Components: query-sql Affects Versions: 3.1.3 Reporter: yann degat Assignee: Diego Pires Plentz Priority: Blocker Attachments: OracleJoinFragment.java, OracleJoinFragment.java, SUP-3701.zip Original Estimate: 10 minutes Remaining Estimate: 10 minutes the "org.hibernate.sql.OracleJoinFragment.addLeftOuterJoinCondition" does not take the "!=" operator into account. it places the "(+)" like this "!(+)=" instead of " (+) !=" ( != is a valid operator for Oracle ) and it returns (+)<(+)> for the '<>' operator here's a patch. (maybe not the best one ) /** * This method is a bit of a hack, and assumes * that the column on the "right" side of the * join appears on the "left" side of the * operator, which is extremely wierd if this * was a normal join condition, but is natural * for a filter. */ private void addLeftOuterJoinCondition(String on) { StringBuffer buf = new StringBuffer( on ); for ( int i = 0; i < buf.length(); i++ ) { char character = buf.charAt( i ); boolean isInsertPoint = OPERATORS.contains( new Character( character ) ) || ( character == ' ' && buf.length() > i + 3 && "is ".equals( buf.substring( i + 1, i + 4 ) ) ) ; if( character == '<' && buf.length() > i + 1 && ">".equals( buf.substring( i + 1, i + 2 ) ) ){ isInsertPoint = false; buf.insert( i, "(+)" ); i += 3 + 2; } if ( isInsertPoint ) { buf.insert( i, "(+)" ); i += 3; } if( character == '!' && buf.length() > i + 1 && "=".equals( buf.substring( i + 1, i + 2 ) ) ){ buf.insert( i, "(+)" ); i += 3 + 2; } } addCondition( buf.toString() ); }
