数据库环境：SQL SERVER 2008R2
我之前有写过打印本月日历的SQL，里头有详细的说明。具体请参考前面的博文——生成本月日历。
全年日历只是在本月日历的基础上加了月信息，并按月份分组求得。
下面直接分享SQL
/*基础数据：年初日期，全年有多少天*/ WITH x0AS ( SELECT CONVERT(DATE, '2015-01-01') AS yearbegin ,CONVERT(DATE, '2015-12-31') AS yearend ,DATEDIFF(DAY, '2015-01-01', '2015-12-31') AS dayscount),/*枚举全年的所有日期*/x1AS ( SELECT DATEADD(DAY, number, yearbegin) AS ndateFROM x0 ,master.dbo.spt_values sptWHERE spt.type = 'P'AND spt.number >= 0AND spt.number <= dayscount),/*罗列全年日期对应的月份，第几周，星期几，本月第几天*/x2AS ( SELECT ndate ,DATEPART(month, ndate) AS nmonth ,DATEPART(week, ndate) AS nweek ,DATEPART(weekday, ndate) AS nweekday ,DATEPART(day, ndate) AS ndayFROM x1),/*按月份、所在周分组，生成全年日历*/x3AS ( SELECT nmonth ,nweek ,ISNULL(CAST(MAX(CASE nweekdayWHEN 1 THEN ndayEND) AS VARCHAR(2)), '') AS 日 ,ISNULL(CAST(MAX(CASE nweekdayWHEN 2 THEN ndayEND) AS VARCHAR(2)), '') AS 一 ,ISNULL(CAST(MAX(CASE nweekdayWHEN 3 THEN ndayEND) AS VARCHAR(2)), '') AS 二 ,ISNULL(CAST(MAX(CASE nweekdayWHEN 4 THEN ndayEND) AS VARCHAR(2)), '') AS 三 ,ISNULL(CAST(MAX(CASE nweekdayWHEN 5 THEN ndayEND) AS VARCHAR(2)), '') AS 四 ,ISNULL(CAST(MAX(CASE nweekdayWHEN 6 THEN ndayEND) AS VARCHAR(2)), '') AS 五 ,ISNULL(CAST(MAX(CASE nweekdayWHEN 7 THEN ndayEND) AS VARCHAR(2)), '') AS 六FROM x2GROUP BY nmonth ,nweek)/*将月份相同的值只在第一行显示*/SELECT REPLACE(CASE WHEN ROW_NUMBER() OVER ( PARTITION BY nmonth ORDER BY nweek ) = 1THEN nmonthELSE -1END, -1, '') AS 月份 ,日 ,一 ,二 ,三 ,四 ,五 ,六FROM x3
代码不算多，60多行，而且也好理解。如果觉得把“周日”放在第一列有点别扭，可以x2中生成所在周时对周日
做一些特别处理就可以了。
贴一下结果
