	ELTMessage nvarchar(200)--错误发生信息
)
--表注释  @value为注释内容  @leve12name为注释表名
EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'错误信息表' , @level0type=N'SCHEMA',
@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'T_ErrorLogTable_tb'
--列注释 @value为注释内容   @leve12nane为注释列名 
EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'编号' , 
@level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'T_ErrorLogTable_tb', 
@level2type=N'COLUMN',@level2name=N'ELTID';
