sqlserver获得数据库非聚集索引的代码

创建Index

	DECLARE @zindex_sql NVARCHAR(max);

设置数据库collation

	DECLARE @sql NVARCHAR(max);
	SET @sql = N'';
	SELECT
		@sql = @sql + N' alter table ' +	[Tables].name  + N' alter column  ' + [Columns].name + N' ' + Types.name  + N'(' + CASE WHEN [Columns].max_length=-1 THEN N'max' else CAST([Columns].max_length/2 AS NVARCHAR(5)) END + N') collate DATABASE_DEFAULT;' + NCHAR(10) + NCHAR(13)
    FROM sys.tables AS [Tables]
        INNER JOIN sys.columns AS [Columns]
            ON [Tables].object_id = [Columns].object_id
        INNER JOIN sys.types AS [Types]
            ON [Columns].system_type_id = [Types].system_type_id
               AND is_user_defined = 0
               AND [Types].name <> 'sysname'

    WHERE Columns.collation_name IS NOT NULL AND CHARINDEX(N'tbl' ,[Tables].name)=1
	ORDER BY [Tables].name,[Columns].name

	SELECT @sql;

　　

删除Index
