I'm trying to find all clustered indexes built on columns of the data type uniqueIdentifier. Obviously this is a terrible choice for a clustered index, and I'm trying to find all of them and remove them. The script that I've written so far returns all clustered indexes for every table that has a uniqueIdentifier on it. Please help. Here is the script:
我正在尝试查找在数据类型uniqueIdentifier的列上构建的所有聚簇索引。显然，对于聚簇索引来说这是一个糟糕的选择，我试图找到所有这些并删除它们。到目前为止，我编写的脚本为每个具有uniqueIdentifier的表返回所有聚簇索引。请帮忙。这是脚本：
select distinct object_name(i.object_id) AS tablename, i.name AS indexname, i.type_desc as type
from sys.indexes i
join sys.index_columns ic on ic.object_id = i.object_id and ic.index_id = i.index_id
join sys.columns c on c.column_id = ic.index_column_id
join sys.types t on t.system_type_id = c.system_type_id
join sys.objects o on o.object_id = i.object_id
where t.name = 'uniqueidentifier'
and i.type_desc = 'clustered'
and object_name(i.object_id) not like 'sys%'
