1.过滤字符串为空的一些记录的话,可以在sql_query中直接加上where来限制,如:
sql_query = \
SELECT a.location_id as id,a.location_id,a.location_name as `location_name`,a.location_name as `name`,a.location_bname,a.attach_id,a.showstatus,CRC32(a.showstatus) as crc32_showstatus,a.is_del,a.status,b.area_name as city_name FROM `ts_rdd_location` a LEFT JOIN `ts_rdd_area` b ON a.city_id = b.area_id where a.attach_id is not null
2.过滤字段为某个具体值的话,可以用setFliter来过滤,如果showstatus要为'Y'的,可以CRC32(a.showstatus) as crc32_showstatus,
然后:
sql_attr_uint = crc32_showstatus
php中调用的时候,
'crc32_showstatus' => sprintf('%u', crc32('Y'))
if (isset($filterArr['crc32_showstatus'])) {
$spx->SetFilter('crc32_showstatus', array($filterArr['crc32_showstatus']));
}
来控制。
