Question

数据库管理员为我的asp.net项目发送了sql命令。但对我来说这很难理解。

命令：

SELECT to_char(FirstDate, 'yyyymmdd') AS EXPR1, SUM(Single) AS SingleFile, SUM(Sum) AS AllFiles ROUND(SUM(SingleSize) / (1024 * 1024 * 1024), 2) AS SingleSize,
            ROUND(SUM(SumSize)/(1024 * 1024 * 1024), 2) AS SumSize
FROM (SELECT FILE, MIN(DATE) AS FirstDate, 1 AS Single, COUNT(*) AS Sum, MAX(Size) AS SingleSize, SUM(Size) AS SumSize
            FROM INETISLE.XFERLOG
            GROUP BY FILE) derivedtbl_1
GROUP BY to char(FirstDate,'yyyymmdd')
ORDER BY 1

输出如下：

EXPR1       SingleFile      SumFile         SingleSize     SumSize
19.11.2014  123123          13423           12312423       23424132

我需要将EXPR1（日期）链接到我的日历。

Asp.net日历控件添加如下：

WHERE ([EXPR1] = ?)

我在哪里将这个WHERE放在我的复杂sql命令上？

我需要选择我在日历上选择的一天。

SELECT to_char(IlkTarih, 'yyyymmdd') AS EXPR1, SUM(Toplam) AS ToplamDosya,     ROUND(SUM(TekilBoyut) / (1024 * 1024 * 1024), 2) AS TekilBoyut,
            ROUND(SUM(ToplamBoyut)/(1024 * 1024 * 1024), 2) AS ToplamBoyut
FROM (SELECT DOSYA, MIN(TARIH) AS IlkTarih, 1 AS Tekil, COUNT(*) AS Toplam, MAX(BOYUT) AS TekilBoyut, SUM(BOYUT) AS ToplamBoyut
            FROM INETISLE.XFERLOG
            WHERE DATE(TARIH) = ?
            GROUP BY DOSYA) derivedtbl_1
GROUP BY to char(IlkTarih,'yyyymmdd')
ORDER BY 1

我在哪里将WHERE命令放在复杂的sql命令上
