SQL Server :: Adding A Relationship - Nvarchar(256) Doesn’t Match
Jan 22, 2011
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. I have put a relationship on aspnet_Users.UserName to another table, so I am baffeled.

Does 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)?

i have created a encrypted string to match with a target string to pass it along with client URL for authentication. it doesn't match. here is an algorithm used to create a encrypted string.
text = "astringtobeencrypted";
string strglobalkey = "mytestglobalkey";
string hexivkey = "testing12345";
ebCryptLib.eb_c_Cipher ci = new ebCryptLib.eb_c_Cipher();
string strhex1 = ConvertStringToHex(strglobalkey);
string strhex2 = ConvertStringToHex(hexivkey);
byte[] bytes = (byte[])ci.EncryptStringRaw(EB_CRYPT_CIPHER_ALGORITHM.EB_CRYPT_CIPHER_ALGORITHM_DES3_ECB,
strhex1, strhex2, text);
return Convert.ToBase64String(bytes);
the above alogithm returns a string which doesn't match with our targetted string provided by the client.
what should i do to match with the targetted string? The client had generated the encrypted string using PHP.

I have a confusing question, I have a user table and it stores all the usual data for a user that you would expect but im trying to figure out how a user could add another user?
Sounds strange but each user in the User table has his own UI which is UserID how could I add another table where UserID can have a relationship with another UserID?
i.e how would I right the syntax for the above question if I wanted to display all the UserIDs friends on a page. How would I add a friend.

I've just taken over looking after a website and well to be honest the way it's been put together is not the best, but I have to make do as the client does not have the money to make major changes.Anyway currently there is data stored in a MsSQL database and some in an XML file. The xml file does have a ContentID attribute which matches the ContentID in a table.Not really done much with XML as I tend to use a database and LINQ.What would be the best way to tie these two together so I could output the results in a gridview for example.

I have two tables as below.
I tried to establish a relation between two tables in such a way that Table_Contracts will still accept NULL values for [PO_No], but [PO_No] on TableContract will be automatically updated when [PO_No] on Table2_PONo changed. Moreover, if you want to delete a record on Table2_PONo, it needs to be stopped if there is a related data in Table_Contracts.
I set a relation with these parameters:
Check existing data on creation or re-enabling>
No
Enforce for replication>
No
Enforce foreign key constraint>
No
Delete Rule>
No Action
Update Rule>
Cascade
I got this error
Introducing FOREIGN KEY constraint 'FK_Table_Contracts_Table2_PONo' on table 'Table_Contracts' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints.
