在 SQL Server 中生成 CREATE INDEX 语句

Question

是否有人有一个脚本来列出 SQL Server 数据库中所有现有索引的 CREATE INDEX 语句？

此线程List of all index & index columns in SQL Server DB 提供了有关如何找到它们的重要提示。但是生成CREATE INDEX 语句的脚本会很棒。有时我们会遇到没有足够数据的情况，或者随着时间的推移在没有文档的情况下以临时方式添加了索引，因此缺少 create 语句。就像我现在所处的情况一样。

谢谢。

Answer 1

使用从 SQL Management Studio 生成脚本并选择“脚本索引”选项（在高级脚本选项下）

我不久前为此写了一些东西。您可能需要根据需要对其进行修改，但至少您有一个骨架。

if exists (select 1 from information_schema.routines where routine_name = 'Script_CreateIndex')
    drop proc Script_CreateIndex
go

create proc Script_CreateIndex (
    @TableName varchar(124)
)
as
begin
    if not exists (select 1 from sys.indexes where object_name(object_id) = @TableName and type_desc in ('CLUSTERED', 'NONCLUSTERED'))
        return

    declare @IndexList table (
        Id int identity,
        IndexName varchar(124),
        IndexDescription varchar(max),
        IndexKeys varchar(max)
    )

    insert @IndexList(IndexName, IndexDescription, IndexKeys)
        exec sp_helpindex @TableName

    if (select count(*) from @IndexList) > 0
    begin
        select '-- Creating indexes for table ' + @TableName

        while exists (select 1 from @IndexList) 
        begin
            declare @Id int, @IndexName varchar(124), @IndexDescription varchar(max), @IndexKeys varchar(max)
            select top 1 @Id = Id, @IndexName = IndexName, @IndexDescription = IndexDescription, @IndexKeys = IndexKeys from @IndexList order by Id
            delete from @IndexList where Id = @Id

            declare @Clustered varchar(10), @Unique varchar(7)

            select @Clustered = case when patindex('%nonclustered%', @IndexDescription) > 0 then '' else ' clustered ' end
            select @Unique = case when patindex('%unique%', @IndexDescription) > 0 then ' unique ' else '' end

            select 'if not exists (select 1 from sys.indexes where name = ''' + @IndexName + ''')'
            select 'begin'
            select char(9) + 'create' + @Unique + @Clustered + ' index [' + @IndexName + '] on [' + @TableName + '](' + @IndexKeys + ')'
            select char(9) + 'select ''Index ' + @IndexName + ' created.'''
            select 'end'
            select 'go'
        end

        select ''
        select ''
    end
end
go

grant exec on Script_CreateIndex to public
select 'Script_CreateIndex compiled.' 'Job'
go

您可以使用“对象资源管理器”窗口逐个表地进行操作

转到 Management Studio 中的 Indexes 文件夹，突出显示该文件夹，然后打开 Object Explorer 窗格

然后您可以“移位选择”该表上的所有索引，如果您右键单击脚本“CREATE TO”，它将为您创建一个包含所有相关索引的脚本。
