I have an SSIS pkg, that gets data from Lotusnotes db and loads into SQL Server, using ODBC Driver for Notessql driver . I have a comments, field, in Lotusnotes which has comments>8000 chars in lotusnotes. Hence I created my destn SQL Table with datatype NVARCHAR(MAX) so that it can uplaod the comments that are >8000 chars.
However, every time I run the ssis pkg , the destn table is bringing only 250 chars ONLY in the comments field , and truncates the rest of the chars.
And I see the reason is because, on my ODBC Serttings for Lotusnotes, There is a section for NOTESSQL options
where the "Max length of text fields" set to 254. hence it brings only 254 chars into SQL.
However, If I increase that option "Max length of text fields" to 8000 or some higher number, the sssis package errors out on the datareader source itself, err is"
"The output column 'comments' has a length that is not valid.
Pl advise how can I load all the comments which are more than 8000 chars from lotus notes into SQL, AND KEEPING THE ODBC settings, the "Max length of text fields" TO 254 Only.

Hi All, The storage reserverd for nvarchar(m) is 2*m+ 2 extra bytes. I understood each character requires because it supports unicode format. Why extra two bytes are required?
Is it bad form to use nvarchar(MAX) in place of column types with specific lengths like nvarchar(50)? Are there performance issues? Because to me (a novice), it appears that I would save space by using nvarchar(MAX) everywhere.
Same question applies to varbinary(MAX) as well.
Thanks
Jim

I have a scenario to sort on an nvarchar (50) field and I need to keep any changes to the sproc in the ORDER BY clause if possible. This field will contain strings such as... abc-217c, abc-15a, abc-9a, abc-7b, abc-17ar, etc... The issue I'm having is when the records are sorted, they are returned as... abc-15a, abc-17ar, abc-217c, abc-7b, abc-9a,etc...ordering numerically on the first numeric character in the string ie, 1,1,2,7,9) However, I need the numeric component to be treated as a whole number and order in this fashion... abc-7b, abc-9a, abc-15a, abc-17ar, abc-217c (7,9,15,17,217, etc) I feel pretty sure that this issue has come up before...can anybody provide a working example that would provide a simple(or not so simple) solution?
Hello, I have a column in my table that is a nvarchar.The information that we need to store in this column has exceeded the limit.Can we simply change the datatype to 'text' ? Will there be any issues that we might experience? Thank you in advance.
i have used nvarchar as my datatype in sql server 2000 now i have decided to change to varchar as i can increase the character length from 4000 to 8000 Do I Lose data if i change the datatype.
I have a table using nvarchar(for what ever reason which beyond me why its a nvarchar...) that I would like to change to a varchar. There is no unicode in the fields so I don't have to worry about but I don't want to lose any text data. Will coverting the data type lose data?
I'm trying to convert a nvarchar datatype to int (ie:1234-56-78 to 12345678) . These values are primary keys in two tables. Both these tables have 3500 rows of this key type. I want to convert this to a int so I can make it a AutoNumber primary key so I can increment it. Is this possible? If so, how do I do it. Do I need to delete the dashes first some how? I fairly new to database adminstration, so any guidance will be greatly appreciated.
I am converting this table to something that will be multi language compliant. My question is, I know that NVARCHAR's take double the space of a VARCHAR. Do I actually need to double the length of the VAL field to store the same amount of data or does the DB handle that?
Basically I want to store a 128 character NVARCHAR.. do I need to set my table up like this:
I need to save some news text in an SQL table. The text can be long. 1. Should I use nvarchar(MAX) or nText? 2. And what is the difference between nText and Text?
Hi all, Please help. I have created a new SQL dB and imported a table from Access to SQL. my date columns in Access have been imported as nvarchar(50). all dates are in the format dd/mm/yyyy.And there is no bad data
My problem is that in the table design of my new SQL Table, if I change the datatype from nvarchar(50) to datetime I get the error "Arithmetic overflow error converting expression to data type datetime"
I know this is telling me that there is a problem with the format of some of the dates but all my dates are defo dd/mm/yyyy ,none of the data has format mm/dd/yyyy ie a 13th month.I know this because I cut the data down to just 2 pieces of data. can someone help me get the format into datetime please Ray..
Is there a way to parse a string to int? this is my example code. quote_id is a string i want to be treated as an int here.
Code Snippet ALTER PROCEDURE [dbo].[GetNextQuoteID] AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; -- Insert statements for procedure here SELECT MAX(quote_id)+1 as id From Quote END
How to return nvarchar(max) from CLR? ---------------------- using System; using System.Data; using System.Data.SqlClient; using System.Data.SqlTypes; using Microsoft.SqlServer.Server;
public partial class UserDefinedFunctions { [Microsoft.SqlServer.Server.SqlFunction(DataAccess = DataAccessKind.Read)] public static SqlString Select_Description(int Obj_ID) {
using (SqlConnection conn = new SqlConnection("context connection=true")) { try { string sql = @"Select description from tbl_detail";
SqlCommand cmd = new SqlCommand(sql, conn); conn.Open(); return (SqlString)cmd.ExecuteScalar();
} catch (Exception e) { throw e; }
finally { conn.Close(); } } }
}; ----------------------
Code above work fine with any [description]< 4000 characters. Get an error if description field have values> 4000 characters.
Try to solve ==> Looking for the net they said change SqlString ==> SqlChars
Here my modify code ------------------------ using System; using System.Data; using System.Data.SqlClient; using System.Data.SqlTypes; using Microsoft.SqlServer.Server;
public partial class UserDefinedFunctions { [Microsoft.SqlServer.Server.SqlFunction(DataAccess = DataAccessKind.Read)] public static SqlString Select_Description(int Obj_ID) {
using (SqlConnection conn = new SqlConnection("context connection=true")) { try { string sql = @"Select description from tbl_detail";
SqlCommand cmd = new SqlCommand(sql, conn); conn.Open(); return (SqlChars)cmd.ExecuteScalar(); //<== is this correct syntax?
} catch (Exception e) { throw e; }
finally { conn.Close(); } } }
}; ------------------------
the error come when compile
Error 1 Cannot implicitly convert type 'System.Data.SqlTypes.SqlChars' to 'System.Data.SqlTypes.SqlString'. An explicit conversion exists (are you missing a cast?)
Please teach me how to solve this problem. Thank you. I'm newbie on CLR and .NET
Hi everybody,I'm using SQL Server Management Studio Express.I'm trying to create a field which contains a text entered by the user. So, it should be able to contain at least 500 characters.I used the type "nvarchar(MAX)". The problem is that the type contains about 50 characters max!!I couldn't find out where and how to fix that. If you have any idea :)Thanks a lot

Hi, I have created a database using VWD to keep values of urls and have structured it as...

I've created an asp.net page that takes the content of text boxes and writes them to a sql table.
The problem is that when I examine the resulting data in the SQL database, I find that the fields written to have had padding added (up to the maximum size of the fields).
I was under the impression that fields of type NVARCHAR did not store padding (only the no of characters being stored).
I've checked it's not the text boxes on the aspx page by explicitly posting values instead of the boxes content and the same thing happens.

I am currently cleaning up my database to get its total size down and am not sure how nvarchar and varchar work exactly.
When defining the length of a varchar or nvarchar in enterprise manager, will that effect the size of the entry (as far as data size) no matter what the length of the entry? In other words, will there be a difference in Data Size for an entry with the length of 4 characters with a definition of varchar(4) versus an entry with the length of 4 characters with a definition of varchar(50).
****If there is no difference, is there any reason in trying to best guess the size to give nvarchar or varchar columns? It would seem easier to just define the lengths of columns which need variable lengths to 200 or 400 just to save time in not trying to best guess what the size might be...*****
