mssql sqlserver 使用sql脚本导出表结构及表说明的方法分享


摘要:
下文举例讲述sqlserver中采用sql脚本输出表结构的方法,如下所示:
实验环境:sqlserver 2008 R2


    SELECT   a.id as [对象Id], 
      CASE WHEN a.colorder = 1 THEN d.name ELSE '' END AS [表名称], 
      CASE WHEN a.colorder = 1 THEN isnull(f.value, '') ELSE '' END AS [表备注], 
      a.colorder AS [字段顺序号], a.name AS [字段名称],
       CASE WHEN COLUMNPROPERTY(a.id, 
      a.name, 'IsIdentity') = 1 THEN '√' ELSE '' END AS [是否标识列], 
      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 = a.id AND sc.colid = a.colid) THEN '√' ELSE '' END AS [是否主键], 
      b.name AS [字段类型], a.length AS [字段长度], COLUMNPROPERTY(a.id, a.name, 'PRECISION') 
      AS [字段精度], ISNULL(COLUMNPROPERTY(a.id, a.name, 'Scale'), 0) AS [字段小数位数], 
      CASE WHEN a.isnullable = 1 THEN '√' ELSE '' END AS [是否允许null], ISNULL(e.text, '') 
      AS [字段默认值], ISNULL(g.[value], '') AS [字段备注], d.crdate AS [对象创建时间], 
      CASE WHEN a.colorder = 1 THEN d.refdate ELSE NULL END AS [对象修改时间]
FROM dbo.syscolumns a LEFT OUTER JOIN
      dbo.systypes b ON a.xtype = b.xusertype INNER JOIN
      dbo.sysobjects d ON a.id = d.id AND d.xtype = 'U' AND 
      d.status >= 0 LEFT OUTER JOIN
      dbo.syscomments e ON a.cdefault = e.id LEFT OUTER JOIN
      sys.extended_properties g ON a.id = g.major_id AND a.colid = g.minor_id AND 
      g.name = 'MS_Description' LEFT OUTER JOIN
      sys.extended_properties f ON d.id = f.major_id AND f.minor_id = 0 AND 
      f.name = 'MS_Description'
ORDER BY d.name, [字段顺序号]
