mssql sqlserver 使用sql脚本生成指定表的索引-创建脚本


摘要:
下文讲述sqlserver中使用sql脚本生成特定表上的所有索引的脚本,如下所示:
实验环境:sql server 2008 R2


  
if exists (
select null from sysobjects where xtype='P'
and name ='pr_outProcInfo'
)
begin
 drop proc pr_outProcInfo
end
 
go

go
---测试
create table test 
(keyId int)

create  index ix_test  on test(keyId) 

go

exec pr_outProcInfo  @tableName=  'test'

go
drop index ix_test on test 
drop table test
