MySQL到SQL Server 2014

Question

我有以下查詢：

SELECT Date(time) AS date, COUNT(*) AS total FROM branches INNER JOIN
stats ON branches.branch_id = stats.branch_id WHERE stats.time BETWEEN
'$from' AND '$to' AND branches.bgroup='$group' GROUP BY date;

但是當我在SQL Server上運行此查詢時，我收到錯誤：

錯誤SQLSTATE [42000]：[Microsoft] [SQL Server的ODBC驅動程序11] [SQL Server]“日期”不是可識別的內置函數名稱。

如何轉換為SQL Server？

Answer 1

SQL Server沒有date()函數。 使用cast()代替：

SELECT CAST(time as DATE) AS dte, COUNT(*) AS total
FROM branches INNER JOIN
     stats
     ON branches.branch_id = stats.branch_id
WHERE stats.time BETWEEN '$from' AND '$to' AND
      branches.bgroup = '$group'
GROUP BY CAST(time as DATE)
ORDER BY CAST(time as DATE);
