sql中查询数据表字段名称的查询语句_数据库技巧

以下为在SQL Server中查看某个表的字段信息的查询语句（以数据库Pubs的jobs表为例）

SELECT     SysObjects.Name as TableName,     
                   SysColumns.Name as ColumnsName,     
                   SysTypes.Name as DateType,     
                   SysColumns.Length as DateLength,     
                   SysProperties.Value as Remark     –列描述     
  FROM       SysObjects,     
                    SysTypes,     
                    SysColumns     
  LEFT  JOIN     SysProperties         
                        ON     (Syscolumns.Id     =     Sysproperties.Id     AND     Syscolumns.Colid     =     Sysproperties.Smallid)     
  WHERE             (Sysobjects.Xtype     =u     OR     Sysobjects.Xtype     =v)     
                        AND     Sysobjects.Id     =     Syscolumns.Id     
                        AND     SysTypes.XType     =     Syscolumns.XType     
                        AND     SysTypes.Name     <>     sysname   
       AND    SysObjects.name    = jobs
如果需要查询整个数据库的所有表的话，就把最后哪个条件去掉即可。
