Group: Forum Members Posts: 190, Visits: 1.3K	Hi, I have a scenario whereby there is a column slip with data type image which allows null and no default value is set since it allows null. I deleted the slip column in the ddt and save. Then I create the column slip again with data type nvarchar(256) which does not allow null with default value (‘’) and save. Then I generate the package and run the package. It tries to drop the column but failed. The reason behind it due to it tries to drop the default constraint for the slip column which does not exist in the first place since it allows null. I’m attaching the log file as a reference for the given problem. • 04/03/2009 7:43:12 PM -> Deploying meta-data for database 'VfsDocumentHope' • 04/03/2009 7:43:12 PM -> Ensuring Filegroups exist on database 'VfsDocumentHope' • 04/03/2009 7:43:12 PM -> Filegroup verification complete. • 04/03/2009 7:43:12 PM -> Ensuring Tables exist on database 'VfsDocumentHope' • 04/03/2009 7:43:14 PM -> The table 'LVELeaves' is being prepared to be modified.

This has to do with the default value and this logic has been changed to circumvent these types of issues within certain environments. Download the most recent beta of 1.6.7 and see if this issue still persists.

Group: StrataFrame Developers Posts: 6.6K, Visits: 6.9K	I have been messing with this for a while and have found a number of issues. First, the deployed database and the package have different file group names. This isn't a big deal, but you may need to account for this if you are going to be deploying in the field on databases that have a file group named "VfsDocument1" when the default file group name will follow the database name because of the $DbName$ parm in the DDT. By default it will try and name the file group "Vfsdocument." That is issue 1. Next, you have a field that has been deleted and then re-added to the database. So this will present an issue once deployed (the field will be missing and you will actually need it). Next, you are trying to convert an Image field into an NVarChar (slip). This will not work either. If you are going to convert from an Image to an NVarChar, you are going to have to take this into account in a pre-post deployment script as it is unknown what to do with this data. Once I fixed these errors (I removed the Slip Field) it worked perfectly.
