Question

我正在尝试在sql server 2016中创建一个表分区。我基本上需要根据年份和季度进行分区。我们在查询中有两个字段来确定它。 periodenddate，它确定决定季度的年份和财政季度，并且是int字段。我需要的第二件事是应该从2000年到2070年创建分区我创建了5个文件组。所以不确定如何在文件组中分配分区

请参阅下面我现有的分区查询。目前只在年内分配并考虑到过去5年。

从2000年到2070年按年分区

CREATE PARTITION SCHEME financialStatementRange  
    AS PARTITION financialStatementPartition  
    ALL TO ([PRIMARY]); 

DECLARE @StartDate DATE = '20000101'
DECLARE @periodenddate DATE = '20700101'

while( @StartDate < @periodenddate) 
begin
ALTER PARTITION SCHEME financialStatementRange
    NEXT USED [PRIMARY];
ALTER PARTITION FUNCTION financialStatementPartition()
    SPLIT RANGE(@StartDate);
   SET @StartDate = DATEADD(year, 1, @StartDate);

end

检查一下，它可能适合你：

CREATE TABLE dbo.Orders
(
    OrderID     integer NOT NULL,
    Name        nvarchar(20) NULL,
    OrderDate   date NOT NULL,

    CONSTRAINT PK__Orders_OrderID
        PRIMARY KEY NONCLUSTERED 
            (OrderID)
        ON [PRIMARY]
)
ON PS (OrderDate);
GO
CREATE CLUSTERED INDEX CX__Orders_OrderDate
ON dbo.Orders (OrderDate)
ON PS (OrderDate)

基于年份和季度的分区表
