使用Thinkphp解決group和count一起使用的問題

使用tp,group和count無法得到想要的sql語句。

M('Report')->group('begin')->where($term)->count();

SELECT COUNT(*) AS tp_count FROM `qdb_report` WHERE ( `type` = 1 ) AND ( `branch` = 59 ) GROUP BY begin LIMIT 1

 

改成子查詢：

$subQuery = M('Report')->group('begin')->where($term)->select(false);
$data['rows'] = M('Report')->table($subQuery . ' a')->count();

SELECT COUNT(*) AS tp_count FROM ( SELECT * FROM `qdb_report` WHERE ( `type` = 1 ) AND ( `branch` = 59 ) GROUP BY begin  ) a LIMIT 1  

得到分組后的總條數。
