用mysql @ -variables执行以下typo3 SELECT的正确方法是什么?
$dbConnection = GeneralUtility::makeInstance(ConnectionPool::class)->getConnectionForTable($extensionTable);
$queryBuilder = $dbConnection->createQueryBuilder();
$query = $queryBuilder
->select('extensionTable.*',
'@dist:=ACOS(ROUND(SIN(RADIANS(geo.coord_lat)) * SIN(RADIANS(52.5234743092278))
+ COS(RADIANS(geo.coord_lat)) * COS(RADIANS(52.5234743092278))
* COS(RADIANS(geo.coord_lon) - RADIANS(13.4122033308763)),10)) * 6380 AS distance',
'@distgrp:=CASE WHEN @dist <10 THEN 1 WHEN @dist<25 THEN 2 ELSE truncate(((@dist-25)/25)+3, 0) END AS dist_group')
->from('extensionTable LEFT JOIN geoTable AS geo ON geo.zip=extensionTable.zip')
->where('pid IN (15,16)');
这不起作用,typo3在@dist var之前插入了'。 不良结果为:
SELECT 'extensionTable'.*, '@dist:=... ' AS 'distance';
错误:执行时发生异常...您的SQL语法有错误;

我希望有人可以帮助我。 :-)(或者我必须使用直接php mysqli()查询。)
您可以防止使用selectLiteral
逃逸。
$queryBuilder
->select(...)
->addSelectLiteral('@dist:=COS(RADIANS(90))')
