Disable all non-clustered indexes

Question

I select a number of non-clustered indexes from my database with the following:

SELECT  sys.objects.name tableName,
        sys.indexes.name indexName
FROM           


        

Answer 1

Using a cursor to script things is more idiomatic than a temp table (and slightly briefer). To re-enable the indexes, replace DISABLE with REBUILD.

DECLARE cur_indexes CURSOR FOR
SELECT  sys.objects.name tableName,
        sys.indexes.name indexName
FROM    sys.indexes
        JOIN sys.objects ON sys.indexes.object_id = sys.objects.object_id
WHERE   sys.indexes.type_desc = 'NONCLUSTERED'
        AND sys.objects.type_desc = 'USER_TABLE'

DECLARE @TblName NVARCHAR(255), @IdxName NVARCHAR(255)

DECLARE @SQL NVARCHAR(MAX)

open cur_indexes
fetch next from cur_indexes into @TblName, @IdxName

WHILE @@FETCH_STATUS = 0
BEGIN
    SELECT @SQL = N'ALTER INDEX ' + @IdxName + N' ON ' + @TblName + ' DISABLE;'

    EXEC sp_sqlexec @SQL    

    fetch next from cur_indexes into @TblName, @IdxName
END

close cur_indexes
deallocate cur_indexes
