Doctrine でカスタム 'REPLACE' 関数を作成しました。しかし、使用するとエラーが発生します。
$result->andWhere("replace(weight,X,C) <= :weight_from")
->setParameter('weight_from',$data['weight_from']);
置換機能:
namespace Doctrine\ORM\Query\AST\Functions;
use Doctrine\ORM\Query\Lexer;
/**
* "REPLACE" "(" StringPrimary "," StringSecondary "," StringThird ")"
*
*
* @link www.prohoney.com
* @since 2.0
* @author Igor Aleksejev
*/
class ReplaceFunction extends FunctionNode {
public $stringPrimary;
public $stringSecondary;
public $stringThird;
/**
* @override
*/
public function getSql(\Doctrine\ORM\Query\SqlWalker $sqlWalker) {
return $sqlWalker->getConnection()->getDatabasePlatform()->getReplaceExpression(
$this->stringPrimary, $this->stringSecondary, $this->stringThird
);
}
/**
* @override
*/
public function parse(\Doctrine\ORM\Query\Parser $parser) {
$parser->match(Lexer::T_IDENTIFIER);
$parser->match(Lexer::T_OPEN_PARENTHESIS);
$this->stringPrimary = $parser->StringPrimary();
$parser->match(Lexer::T_COMMA);
$this->stringSecondary = $parser->StringPrimary();
$parser->match(Lexer::T_COMMA);
$this->stringThird = $parser->StringPrimary();
$parser->match(Lexer::T_CLOSE_PARENTHESIS);
}
}
AbstracPlatfrom.php には以下が含まれます。
/**
* Returns the replace of a text field.
*
* @param string $column
* @param string $x
* @param string $y
*
* @return string
*/
public function getReplaceExpression($column,$x,$y)
{
return "REPLACE($column,'$x','$y')";
}
