sqlserver 简单查询语句

1.sqlserver查询表，数据量，数据注释
SELECT a.name TableName,b.rows TotalCount,D.Description AS [Description]
FROM sysobjects a INNER JOIN sysindexes b ON a.id=b.id
join (
select a.name AS name,isnull(g.[value], ‘未定义’) AS Description
from sys.tables a left join
(SELECT * FROM sys.extended_properties WHERE NAME=’Description’ ) g
on (a.object_id = g.major_id AND g.minor_id = 0) ) D
ON D.name = A.name
WHERE b.indid IN(0,1) AND a.Type=’U’ and a.name not in (”)
order by b.rows desc;
2.sqlserver 查询表结构
SELECT CASE WHEN col.colorder = 1 THEN obj.name
ELSE ”
END AS 表名,
col.colorder AS 序号 ,
col.name AS 列名 ,
ISNULL(ep.[value], ”) AS 列说明 ,
t.name AS 数据类型 ,
col.length AS 长度 ,
ISNULL(COLUMNPROPERTY(col.id, col.name, ‘Scale’), 0) AS 小数位数 ,
CASE WHEN COLUMNPROPERTY(col.id, col.name, ‘IsIdentity’) = 1 THEN ‘√’
ELSE ”
END AS 标识 ,
CASE WHEN EXISTS ( SELECT 1
FROM dbo.sysindexes si
INNER JOIN dbo.sysindexkeys sik ON si.id = sik.id
AND si.indid = sik.indid
INNER JOIN dbo.syscolumns sc ON sc.id = sik.id
AND sc.colid = sik.colid
INNER JOIN dbo.sysobjects so ON so.name = si.name
AND so.xtype = ‘PK’
WHERE sc.id = col.id
AND sc.colid = col.colid ) THEN ‘√’
ELSE ”
END AS 主键 ,
CASE WHEN col.isnullable = 1 THEN ‘√’
ELSE ”
END AS 允许空 ,
ISNULL(comm.text, ”) AS 默认值
FROM dbo.syscolumns col
LEFT JOIN dbo.systypes t ON col.xtype = t.xusertype
inner JOIN dbo.sysobjects obj ON col.id = obj.id
AND obj.xtype = ‘U’
AND obj.status >= 0
LEFT JOIN dbo.syscomments comm ON col.cdefault = comm.id
LEFT JOIN sys.extended_properties ep ON col.id = ep.major_id
AND col.colid = ep.minor_id
AND ep.name = ‘MS_Description’
LEFT JOIN sys.extended_properties epTwo ON obj.id = epTwo.major_id
AND epTwo.minor_id = 0
AND epTwo.name = ‘MS_Description’
WHERE obj.name = ‘m_rec_save’–表名
ORDER BY col.colorder ;
