SQL查索引

方法1. 使用系统表

SELECT  indexname = a.name , tablename = c. name , indexcolumns = d .name , a .indid
FROM    sysindexes a JOIN sysindexkeys b ON a .id = b .id  AND a .indid = b.indid
        JOIN sysobjects c ON b .id = c .id
        JOIN syscolumns d ON b .id = d .id  AND b .colid = d .colid
WHERE   a .indid NOT IN ( 0 , 255 )  
-- and   c.xtype='U'   and   c.status>0 -- 查所有用户表
AND c .name = 'MES_4MSCAN' --查指定表
ORDER BY c. name ,  a.name ,  d.name

方法2. 使用系统存储过程

sp_helpindex 'Tablename'
