如何在 PRIMARY 文件组上创建索引？

Question

CREATE NONCLUSTERED INDEX index
ON table (column1)
INCLUDE (column2, column3) ON ????;

table 被划分为 3 个文件组我想创建物理存储在 PRIMARY 文件组中的索引我该怎么做？

Answer 1

您的语法是正确的 - 但是您只需要使用 [] 转义 PRIMARY，即：

CREATE NONCLUSTERED INDEX IX1
ON table (column1)
INCLUDE (column2, column3) 
ON [PRIMARY];

如果您要移动现有索引，则需要 drop the existing one:

CREATE NONCLUSTERED INDEX IX1
ON table (column1)
INCLUDE (column2, column3) 
WITH (DROP_EXISTING = ON)
ON [PRIMARY];

How can i create an index on the PRIMARY filegroup?
