DataSource Controls :: Replace All Varchar To Nvarchar?
Apr 1, 2010
i want to convert all my database columns whose data type is char,varchar, nchar to nvarchar datatype. But the main problem is that some of my primary key, foreign key columns are also of varchar datatype. So when i try to change their datatypes to nvarchar then i receive the errors related to constraints of Primary Key, Unique Key and indexes. how to change the datatypes to nvarchar after droping the constraints and after changing all constraints will apply again. I also want that no data loss will occur.

I have an output parameter called '@packIds', that I create in ADO.Net using the code below:
SqlParameter packIdPara = new SqlParameter("@packIds", null);
packIdPara.SqlDbType = SqlDbType.VarChar;
packIdPara.Direction = ParameterDirection.Output;
sqlCmd.Parameters.Add(packIdPara);
How will I specify that the parameter '@packIds' is of max size? I cannot find any code for this.

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)?

On one of our applications we are getting a timeout error on an 'additional details' field in our database, the field type is nVarChar(MAX).
The error seems to be happening when a user enters more than 4000 characters into the additional details field. It is my understanding that this fieldtype can store up to 8gb of data and should be used in stead of the "Text" field type?
We have since limited the user from entering more than 4000 characters via the application, however the DB still contains legacy data - when the 'additional details' with more than 4000 characters is pulled out - "Timeout Error".

I have a little problem developing a SQL Select Statement on a column that is formatted pretty badly. Firstly, the Database has already been created and filled with Data in a Test Environment, I'm not sure if the format is the same or has been updated in Production but since I'm only able to work with the Test Environment right now I'm stuck with using what I have. The Column in one Table shows a Snapshot of a clients account which is set to VarChar(50) but the actual data in the column is formatted like a money format (with a $ and decimal point so for example "$5,000.00" would be an entry in one Row).
What I'm trying to do is a create a WebService that will be used in a iPhone Application and one of the Methods needs to just give a quick display of the total value of all Clients with each specific company but I can't perform a SUM function on a VarChar column and I've tried to CAST and CONVERT the column into money, int, decimal and just about every format I can think of but I keep getting an error stating that I convert the data type varchar to which ever one I'm trying. I think it has something to do with the $ already listed in the Column, so I wanted to know what I could do to either remove the $ sign (like a Trim option) or if there is a better way of doing this that I can't think of. I know the best option would be to convert the column to the appropriate format but as I said, this was a previously designed system and I'm not sure if the Production area is the same (most likely not).
Here's what I've tried so far:
