对于Partition表而言,是否Global Index 和 Local Index 可以针对同一个字段建立? 实验证明,对单独的列而言,要么建立 Global Index, 要么建立 Local Index.不能既建立 Global Index, 又建立 Local Index === Test Case ===#### Testcase - 0809 - 1 It is not possible to create both Global Index and Local Index for…

有时工作中要建个分区函数,可是像日期这种分区函数要是搞个几百个的值那不是要搞死我.于是写了点代码自动生成一个从1990年开始的按月的分区函数和对应的分区主题 USE [TestDB] GO DECLARE @STR NVARCHAR(MAX) SET @STR = 'CREATE PARTITION FUNCTION [PF_RangeByMonth_FromYear1990](DATETIME) AS RANGE LEFT FOR VALUES (' DECLARE @STR2 NVARCHA…
