The error message I\'m obtaining when trying to drop a column:
The object \'defEmptyString\' is dependent on column \'fkKeywordRolleKontakt\'.
Msg
I could solve the problem now. I'm sorry, I did not copy the full error message, which was:
Msg 5074, Level 16, State 1, Line 1
The object 'defEmptyString' is dependent on column 'fkKeywordRolleKontakt'.
Msg 5074, Level 16, State 1, Line 1
The object 'FK_tlkpRolleKontakt_tlkpKeyword' is dependent on column 'fkKeywordRolleKontakt'.
Msg 4922, Level 16, State 9, Line 1 ALTER TABLE DROP COLUMN fkKeywordRolleKontakt failed because one or more objects access this column.
I could generate a script to drop the column by right-clicking on the column entry (dbo.tlkpRolleKontakt > Columns > fkKeywordRolleKontakt) (in MSSQL Server Manager), selecting Modify and deleting the column. Then Table Designer > Generate Change Script generated the necessary commands:
ALTER TABLE dbo.tlkpRolleKontakt
DROP CONSTRAINT FK_tlkpRolleKontakt_tlkpKeyword
EXECUTE sp_unbindefault N'dbo.tlkpRolleKontakt.fkKeywordRolleKontakt'
ALTER TABLE dbo.tlkpRolleKontakt
DROP COLUMN fkKeywordRolleKontakt
