php-sql-creator: alias not added to function columns #77

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
Any alias that is connected to a function or aggregate in SELECT is not added 
to the SQL string in php-sql-creator->processFunction.

Solution:

Add processAlias at a convenient location.

In case anyone else is looking, this will fix it right up:

I also had problems with functions and aliases.
Solved the problem with the following code:

--- PHP-SQL-Parser/php-sql-creator.php --- Line: 394...

        protected function processFunction($parsed) {
            if (($parsed['expr_type'] !== 'aggregate_function') && ($parsed['expr_type'] !== 'function')) {
                return "";
            }

            if ($parsed['sub_tree'] === false) {
                return $parsed['base_expr'] . "()";
            }

            $sql = "";
            foreach ($parsed['sub_tree'] as $k => $v) {
                $len = strlen($sql);
                $sql .= $this->processFunction($v);
                $sql .= $this->processConstant($v);
                $sql .= $this->processColRef($v);
                $sql .= $this->processReserved($v);

                if ($len == strlen($sql)) {
                    throw new UnableToCreateSQLException('function subtree', $k, $v, 'expr_type');
                }

                $sql .= ($this->isReserved($v) ? " " : ",");
            }

            /** $alias === ISSO FOI ACRESCENTADO POR Guilherme Ethur <gethur@hotmail.com>

            if (isset($parsed['alias'])) {
                $alias = $this->processAlias($parsed['alias']);
            }else{
                $alias = "";
            }            

            return $parsed['base_expr'] . "(" . substr($sql, 0, -1) . ") $alias"; //a variável $alias é código de guilherme ethur

        }

I think, this issue has been solved. Can you check that with r377 ?
