Column does not allow nulls. INSERT fails
Category: Troubleshooting & error messages
Date: 08 Jun 2009
Product: SQL Compare
The following error may be returned by SQL Server when synchronizing the schema of two databases:
Error: Error Comparing DB1 vs DB2 : Cannot insert the value NULL into column 'YourColumn', table
'database.dbo.tmp_rg_xx_MyTable'; column does not allow nulls.
INSERT fails.
This error will occur if you are adding a new column to an already-populated table and the new column does not allow null values.
The only way to get around this situation is to assign a default value to the column in the source database. Alternatively, set the column to allow nulls for the purposes of the synchronisation and then set it back after you have the correct data inserted.
