SQL Server获取表结构信息(字段名、类型、长度、精度、小数位数、主键、自动增长)

获取表结构的一些简要信息，可以生成自己需要的字典，简单又实用！

以数据表MF_MO为例：

SELECT OBJECT_NAME(B.ID) 表名,B.COLORDER 序号,B.NAME 字段名称,C.NAME 字段类型,B.PREC 精度级别,B.SCALE 小数位数,
    CASE WHEN NOT F.ID IS NULL THEN 'TRUE' ELSE '' END 是否主键,
    CASE WHEN COLUMNPROPERTY(B.ID,B.NAME,'ISIDENTITY') = 1 THEN 'TRUE' ELSE '' END AS 是否自动增长,
    CONVERT(VARCHAR(1000),ISNULL(G.VALUE,'')) 字段说明
FROM SYSOBJECTS A INNER JOIN SYSCOLUMNS B ON A.ID=B.ID INNER JOIN SYSTYPES C ON B.XTYPE=C.XUSERTYPE
    LEFT JOIN SYSOBJECTS D ON B.ID=D.PARENT_OBJ AND D.XTYPE='PK'
    LEFT JOIN SYSINDEXES E ON B.ID=E.ID AND D.NAME=E.NAME
    LEFT JOIN SYSINDEXKEYS F ON B.ID=F.ID AND B.COLID=F.COLID AND E.INDID=F.INDID
    LEFT JOIN SYS.EXTENDED_PROPERTIES G ON B.ID=G.MAJOR_ID AND B.COLID=G.MINOR_ID
WHERE A.XTYPE='U' AND OBJECT_NAME(B.ID)='MF_MO'

执行结果如下：
