修改字段说明
string sql = @" if exists ( select * FROM [{0}].sys.extended_properties PFD with(nolock) left join [{0}].sys.columns C with(nolock) ON PFD.class=1 AND C.[object_id]=PFD.major_id AND C.column_id=PFD.minor_id left JOIN [{0}].sys.objects O with(nolock) ON C.[object_id]=O.[object_id] AND O.type='U' AND O.is_ms_shipped=0 where C.name='{2}' and O.name='{1}' ) begin USE [{0}]; EXEC sp_updateextendedproperty N'MS_Description', '{3}', N'user', N'dbo', N'table', N'{1}', N'column', N'{2}' end else begin USE [{0}]; EXECUTE sp_addextendedproperty N'MS_Description', '{3}', N'user', N'dbo', N'table', N'{1}', N'column', N'{2}' end "; //判断是否存在，不存在新增，存在修改 dbName = dbName.Replace('\'', ' '); sql = string.Format(sql, dbName, TableName, rowName, Description); |
实现代码也比较简单，在此提供我写的代码供大家吐槽。
