View 6 RepliesDoes it make a difference in terms of the actual size of the database if I define one of the columns as nvarchar(100)? If there are restrictions on the form as for how much you can input, let's say 50 characters, does the db save blank spaces from character 51-100 and create a database that is larger than it would be it the column was defined as nvarchar(50)?

The following datatype or size property of <Tablename>.<Columnname> doesn't match <Tablename>.<Columnname>. When creating a foreign key relationship, the data types and other properties of selected columns must match. Select a column with the same data types and other properties as the related column. The properties that must match are Data type, Length, Precision, Scale, and Collation.
I am trying to add a constraint to my database and I keep get the above error. I can find Data type, length, and Collation in the properties. What are precision and scale in this context. I don't see such settings. Specifically I am trying to add a relationship from the aspnet_Membership table to a table that I added.
