I tried this:

ALTER TABLE My.Table DROP MyField

and got this error:

-MyField is not a constraint.

-Could not drop constraint. See previous errors.

There is just one row of data in the table and the field was just added.

EDIT: Just to follow up, the sql was missing COLUMN indeed. Now I get even more seriously looking errors though:

  • The object ‘some_object__somenumbers’ is dependent on column ‘MyField’
  • ALTER TABLE DROP COLUMN MyField failed because one or more objects access this column.

EDIT:

ALTER TABLE TableName DROP Constraint ConstraintName

worked, after that I was able to use the previous code to remove the column. Credit goes to both of you, thanks.

  1. Brian solved your original problem – for your new problem (The object ‘some_object__somenumbers’ is dependent on column ‘MyField’) it means you have a dependancy issue. Something like an index, foreign key reference, default value, etc. To drop the constraint use:

    ALTER TABLE TableName DROP ConstraintName

    Also – you’ll need to drop all the constraints dependant on that column before it’ll let you drop the column itself.
