问题
I have a database in SQL Azure and I am wanting to use a script to drop all the column store indexes.
I am connecting using SSMS using the SQL admin login of the SQL Server.
I am using this script:
declare @sql nvarchar(max);
set @sql = N'';
select @sql = @sql + N'DROP INDEX ' + OBJECT_SCHEMA_NAME(i.OBJECT_ID) + '.' + i.name + N' ON ' + OBJECT_SCHEMA_NAME(i.OBJECT_ID) + '.' + o.name + ';
'
FROM sys.indexes AS i INNER JOIN sys.tables AS o ON i.[object_id] = o.[object_id]
where i.name is not null and o.name is not null and i.type_desc like '%COLUMN%'
PRINT @sql;
EXEC sp_executesql @sql;
An example statement:
DROP INDEX [dbo].[CCI_MyTable] ON [dbo].[MyTable];
When run, this generates error:
Incorrect syntax near the keyword 'ON'.
If I try just:
DROP INDEX [dbo].[CCI_MyTable]
This generates error:
Cannot drop the index 'dbo.CCI_MyTable', because it does not exist or you do not have permission.**
In SSMS, I can see the SQL SERVER admin user exists in the [master] database, but does not exist in the DATABASE I am working in.
Within this DATABASE, I am running as 'dbo':
SELECT USER_NAME() -- DBO
SELECT CURRENT_USER; -- DBO
Shouldn't dbo have permissions to drop indexes?
ASK:
What is the proper way to go about this? Do I need to add the admin user to this database? If that user existed, and I connect with SSMS, would user_name() then be that user rather than dbo?
回答1:
It seems the problem was preceding the index name with the schema (although, I swear many examples I've read do just that).
So the correct script syntax is:
declare @sql nvarchar(max);
set @sql = N'';
select @sql = @sql + N'DROP INDEX ' + i.name + N' ON ' + OBJECT_SCHEMA_NAME(i.OBJECT_ID) + '.' + o.name + ';
'
FROM sys.indexes AS i INNER JOIN sys.tables AS o ON i.[object_id] = o.[object_id]
where i.name is not null and o.name is not null and i.type_desc like '%COLUMN%'
PRINT @sql;
EXEC sp_executesql @sql;
