Sql server 从Excel更新SQL Server的列说明

我工作的地方有一些数据库的数据字典，这些数据库是用Excel文件创建的，格式如下：

 Database|Instance  |Table    |Column   |Description  
 BD1     |dbo       |Table1   |Column1  |DescriptionA
 BD1     |dbo       |Table1   |Column2  |DescriptionB
 BD1     |dbo       |Table1   |Column3  |DescriptionC
 BD2     |dbo       |Table1   |Column1  |DescriptionD

我需要更新列的描述。我知道我可以用SSMS一列一列地完成，但这需要做很多工作。 据我所知，我必须更新下表：sys.extended\u properties

是否有工具或某种方法可以执行这样的masive更新？

将电子表格导入SQL Server表。 编写一个游标在表中循环，使用以下命令添加每个属性：

   Declare   @sql as nvarchar(max)
            , @Database as nvarchar(max)
            , @Instance as nvarchar(100)
            , @Table as nvarchar(100)
            , @Column as nvarchar(100)
            , @Description as nvarchar(100)

    Declare mycursor cursor for Select [Database], [Instance], [Table], [Column], [Description] from MyImportedTable
    open mycursor
    fetch next from mycursor into @Database, @Instance, @Table, @Column, @Description
    while @@FETCH_STATUS= 0
        begin
        set @sql = 'EXEC [' + @Database + '].[' @Schema + '].sp_addextendedproperty   
                    @name = N''Description'',   
                    @value = ''' + @Description + ''',  
                    @level0type = N''Schema'', @level0name = ' + @Instance + ',  
                    @level1type = N''Table'',  @level1name = ' + @Table + ',  
                    @level2type = N''Column'', @level2name = ' + @Column + ';'
        EXEC (@sql)
        fetch next from mycursor into @Database, @Instance, @Table, @Column, @Description
        END
    close mycursor
    deallocate mycursor
