Hi,

I use the following code to drop a column from a table named firstTable:

alter table FirstTable
drop column [firstTable.desc]

I get the following error:
ALTER TABLE DROP COLUMN firstTable.desc failed because one or more objects access this column.

The table is not related to any other table, I just created it for practice. So, I don't understand what objects access the collumn!

What type of column is this? Make sure there are no constants on this column.

Is there anymore errors listed? I believe it should tell you what is dependent on this column

The column is of type varchar(100). I don't believe there any constraints. When I first created it, I added a default text. Other than that, there are no constrains

Here is a script that will delete the column along with its default constraint. Replace MYTABLENAME and MYCOLUMNNAME appropriately.

declare @default sysname, @sql nvarchar(max)  select @default = name  from sys.default_constraints  where parent_object_id = object_id('MYTABLENAME') AND type = 'D' AND parent_column_id = (     select column_id      from sys.columns      where object_id = object_id('MYTABLENAME')     and name = 'MYCOLUMNNAME'     )  set @sql = N'alter table MYTABLENAME drop constraint ' + @default exec sp_executesql @sql  alter table MYTABLENAME drop column MYCOLUMNNAME  go
