MySQL 到 SQL Server 2014

Question

我有以下查询:

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;

但是当我在 SQL Server 上运行这个查询时，我得到了错误:

error SQLSTATE[42000]: [Microsoft][ODBC Driver 11 for SQL Server][SQL Server]'Date' is not a recognized built-in function name.

如何转换为 SQL Server？

Answer 1

SQL Server 没有date() 函数。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);
