Fixed version (ground truth):

    return "String_Node_Str";
  }
  StringBuilder builder=new StringBuilder();
  for (  JoinElement joinElement : joinElements) {
    ModelElement colA=joinElement.getColA();
    String tableA=getTableName(colA);
    String tableAliasA=joinElement.getTableAliasA();
    String columnAName=getColumnName(colA);
    boolean hasTableAliasA=!StringUtils.isEmpty(tableAliasA);
    ModelElement colB=joinElement.getColB();
    String tableB=getTableName(colB);
    String tableAliasB=joinElement.getTableAliasB();
    String columnBName=getColumnName(colB);
    boolean hasTableAliasB=!StringUtils.isEmpty(tableAliasB);
    String operator=joinElement.getOperator();
    if (joinClauseStartsWithWrongTable(leftTable,getTable(colB)) && !hasTableAliasA && !hasTableAliasB) {
      if (ConnectionUtils.isSybaseeDBProducts(getDbmsName())) {
        schemaName=ColumnSetHelper.getTableOwner(colA);
      }
      tableA=toQualifiedName(catalogName,schemaName,tableA);
      buildJoinClause(builder,tableB,tableAliasB,columnBName,hasTableAliasB,tableA,tableAliasA,columnAName,hasTableAliasA,operator);
    }
 else {
      if (ConnectionUtils.isSybaseeDBProducts(getDbmsName())) {
        schemaName=ColumnSetHelper.getTableOwner(colA);
      }
      tableB=toQualifiedName(catalogName,schemaName,tableB);
