我想使用以下查询在表中创建聚集列存储索引：
CREATE CLUSTERED COLUMNSTORE INDEX cci
ON agl_20180319_bck
我收到此错误：
消息 35343，级别 16，状态 1，第 6 行 语句失败。列“memberOf”的数据类型不能参与列存储索引。省略列“memberOf”。
“memberOf”采用以下格式：memberOf(nvarchar(max)).
如何克服/忽略这个错误，它是什么意思？
I have the following query:
DECLARE @value as nvarchar(max)
SET @value = '(company.[department] LIKE ''Development'')';
I would like to extract the word between brackets keep it in a value and then put as input in a replace function like this.
select replace(@value, @department, 'another_string');
You will say probably why I don't do it immediately with the replace function. The case is that this department string may change dynamically to another string for example country and I would like every time …
我需要制作一些机制来检查表X是否是列存储的,以及是否不进行转换.我知道要将表X转换为集群列存储索引,我们可以使用以下代码:
CREATE CLUSTERED COLUMNSTORE INDEX MyColumnStoreIndex
ON Table_X
我想创建一个查询,检查表是否包含列存储索引.提前致谢.
