Cannot insert NULL - URL Manager - 2.2.5.2. MSSQL

Hi,

Using "mojoPortal Version 2.2.5.2 MSSQL" I was attempting to add a friendly URL mapping from the URL Manager (Admin/UrlManager.aspx). Typing in a URL and choosing from the DropDownList, then pressing Add New URL Mapping, causes a SQL Exception.

"System.Data.SqlClient.SqlException: Cannot insert the value NULL into column 'UrlID', table 'MojoPortal.dbo.mp_FriendlyUrls'; column does not allow nulls. INSERT fails."

I created the entry manually with SSMS incrementing the PK value by one. I presume this is a bug with the code not generating a unique ID, since when creating the pages in the first place they all seem to have friendly URLS mapped to them.

Or perhaps the UrlID field should be an identity column? If so, I did copy a this mojoportal database from another mojoportal DB - this may have lost the identity specification.....

Re: Cannot insert NULL - URL Manager - 2.2.5.2. MSSQL

Hi,

Yes, UrlID is a primary key and identity auto increment column, so it sounds like you lost this property. Normally this would not be lost in restoring a db from one machine to another, but importing tables from one db to another will lose things like primary keys, foreign keys, identity specifications.

So what I would be worried about is what else got lost on other tables in addition to this one.

Best,

Joe
