Datatypes Nchar/nvarchar Vs Char/varchar
Dec 2, 2005can anybody please explain me why microsoft using nvarchar/nchar instead of varchar/char in northwind database and pubs database. I know if a column holds unicode data you should use nvarchar or nchar but for me all those tables in northwind/pubs are not holding unicode data. but still why microsoft settled for nchar/nvarchar.

Nchar, Varchar,char?
Jan 11, 2008What is the difference between the above data types in SQL? Which datatype should I use if I wanted both numbers and characters?
View 1 Replies View RelatedUsage Of Varchar/nvarchar Data Types
Oct 2, 2007I am coming to SQL Server from Access and using it mostly for making ASP.NET web apps.
I am not sure I correctly understand the characteristics of the varchar data type and I'm so far unable to find a basic explanation.
It seems that the benefit of this data type is that the actual disk storage involved varies according to what is in a given record's column. So for a column defined as varchar(500), a record where the column uses all 500 characters will use more bytes on disk than a record where the column uses only one.
This would seem to imply that unless there were some reason to limit the characters allowed into a column, it would be an advantage to define large columns, say varchar(8000), especially for memo type fields, or fields such as addresses where it seems like clients are always asking for more space as time passes.
Is this right? Is there any downside to defining large varchar columns assuming they do not conflict with business rules?
Many thanks

The Data Types Varchar And Varchar Are Incompatible In The Modulo Operator
Jan 4, 2008I am trying to create a store procedure inside of SQL Management Studio console and I kept getting errors. Here's my store procedure.
Code Block
CREATE PROCEDURE [dbo].[sqlOutlookSearch]
-- Add the parameters for the stored procedure here
@OLIssueID int = NULL,
@searchString varchar(1000) = NULL
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
IF @OLIssueID <> 11111
SELECT * FROM [OLissue], [Outlook]
WHERE [OLissue].[issueID] = @OLIssueID AND [OLissue].[issueID] = [Outlook].[issueID] AND [Outlook].[contents] LIKE + ''%'' + @searchString + ''%''
ELSE
SELECT * FROM [Outlook]
WHERE [Outlook].[contents] LIKE + ''%'' + @searchString + ''%''
END
And the error I kept getting is:
Msg 402, Level 16, State 1, Procedure sqlOutlookSearch, Line 18
The data types varchar and varchar are incompatible in the modulo operator.
Msg 402, Level 16, State 1, Procedure sqlOutlookSearch, Line 21
The data types varchar and varchar are incompatible in the modulo operator.
Any help is appreciated.
Conversion From Char To Nchar
Apr 16, 2004Hello,
I am trying to convert a single code page MS Server database into a unicode database, using the unicode data types,NCHAR, NVARCHAR, NTEXT. The problem is that in the original database, indexes and constraints have been defined on the tables whose configurations need to be changed. As a result, the ALTER TABLE command fails. Are there any other alternative solutions?
Also, data from the old database needs to be preserved. The objective is to create a unicode database which keeps the old data intact as well as accepts the new data in unicode.
It would be great if you could help!
Thanks,
Sheetal.

Using Nvarchar(max) For All Data Types In A Survey System
Apr 23, 2008I am working on a survey system with another DB Engineer.Our current design includes 1 table per Question Type (Numeric, Boolean, Text), Response values are tightly coupled based on data being entered, to keep things simple assume there are only 6 tables in this this system (1 for each Question Type to define the "rules" of the data entered, and 1 for each Response collection).He is a former .Net programmer and has been talking with the .Net guys on the project and he is proposing that we abstract our Question Types to use one table and store the Input Values all as nvarchar(max).This obviously simplifies the DB design and reduces the amount of work I will need to do so I should be all for it. I guess I am a little concerned that we are no longer tightly coupling the data types and essentially leaving all the validation up to the application. Also should I be worried that a bunch of bit data will be stored as 1/0 in an nvarchar(max) column?Thanks,-John

Apr 10, 2008When I tried to insert armenian by doing the following
insert into tablex (field1) values (N'testdata')
it does not display in query analyzer or in the database as armenian.
When I copy this to word it does not convert it.
What else am I supposed to do to get that information to redisplay the correct way and I would appreciate any tutorials or samples you can show or direct me to.

Changing Char/NChar Column From NOTNULL To NULL
Apr 19, 2008Hi I have a table, which contains Char and NChar NOT NULL columns
Now I need to change it to NULL, when I use the following command, it fails for the following error,
The command I used,
ALTER TABLE <TableName>
ALTER COLUMN <ColName> CHAR NULL
ALTER TABLE <TableName>
ALTER COLUMN <ColName> NCHAR NULL
Msg 8152, Level 16, State 13, Line 1
String or binary data would be truncated.
The statement has been terminated.
But for the same table, the below command executes fine,
ALTER TABLE <TableName>
ALTER COLUMN <ColName> SMALLINT NULL
Also I can change the NULLABILITY from NOTNULL to NULL using Enterprise Manger, editing the table using Table Design and selecting Allow Nulls option.
I need a script to accomplish this task.
Any help would be greatly appreciated.

This Stored Procedure Can Be Used To Search And Replace Substring In The Char, Nchar,
Jan 9, 2006#1 This stored procedure can be used to search and replace substring in the char, nchar, varchar and nvarchar columns in all tables in the current database. You should pass the text value to search and the text value to replace. So, to replace all char, nchar, varchar and nvarchar columns which contain the substring 'John' with the substring 'Bill', you can use the following (in comparison with the SetTbColValues stored procedure, this stored procedure replace only substring, not the entire column's value):
EXEC replace_substring @search_value = 'John', @replace_value = 'Bill'

Feb 18, 2008Hello,
I am trying to write a small dynamic sql statement and I am receiving the following error when working with a bit data type.
The data types varchar and bit are incompatible in the add operator
Here is what I have:
Code Snippet

set nocount on
declare @sql nvarchar(MAX)
-- Check for user existence
select @sql = 'if (' + @ProcAccess + ' = 1)

After I execute, that is why I receive the error. Any advice would be appreciated!

T-SQL (SS2K8) :: Conversion From Varchar To Strong Data Types
Mar 21, 2013There are a few databases I work with that have been designed where varchar columns are used to store what actually displays on the front end as Ints, Decimals, Varchars, Datetimes, checkboxes.
I often have to write integrations with these databases bringing data in and prefer to validate the data whilst loading from the staging tables.
I have seen allsorts of values being passed into the staging tables that will load into the target database because the columns are all varchars but the values don't display on the front end because the app actively filters bad values out.
What I would like to do is for my validation scripts to warn up front of potentially invalid datatypes. My problem is that forexample the ISNUMERIC() function return 1 for the value ',1234' but a CONVERT(NUMERIC, ',1234') or CAST(',1234' AS NUMERIC) will fail with a "Error converting data type varchar to numeric).
I've been trying to locate a set of reliable datatype testing functions that will reliably determine if a varchar can be converted to a given data type or not.

The Data Types Ntext And Varchar Are Incompatible In The Equal To Operator
Feb 25, 2006Hi,
If I make a select query on my table, this error appears:
"The data types text and varchar are incompatible in the equal to operator"
In my table , I have 4 fields with "text" datatype.
My query is like : "Select * from table where field1='test'"
It's seems to be simple, but it doesn't work!!!
Thanks
Datatype Question Varchar(max), Varchar(250), Or Char(250)
Oct 18, 2007
I have a table that contains a lot of demographic information. The data is usually small (<20 chars) but ocassionally needs to handle large values (250 chars). Right now its set up for varchar(max) and I don't think I want to do this.
How does varchar(max) store info differently from varchar(250)? Either way doesn't it have to hold the container information? So the word "Crackers" have 8 characters to it and information sayings its 8 characters long in both cases. This meaning its taking up same amount of space?
Also my concern will be running queries off of it, does a varchar(max) choke up queries because the fields cannot be properly analyzed? Is varchar(250) any better?
Should I just go with char(250) and watch my db size explode?
Usually the data that is 250 characters contain a lot of blank space that is removed using a SPROC so its not usually 250 characters for long.
Any insight to this would be appreciated.
How To Compare Nvarchar(15), Char(5), And String
Jan 31, 2008I have used a query statement with the following WHERE string to 'Fill' a dataset.
"AND (A.ApptsDate > '" & strApptPreDate & "' OR (A.ApptsDate = '" & strApptPreDate & "' AND A.ApptsTime >= '" & strApptPreTime & "' ))" & _ and strApptPreTime is defined as:Dim strApptPreTime As String = SomaShared.strPadTime(CStr(dApptCalcNewDate.Hour) + ":" + CStr(dApptCalcNewDate.Minute))
Somehow, the dataset showed only the ApptsTime after 10 am. After more than 2 weeks of debugging, I still can see a dataset watch for > 10 amAppsTime only. Now I am guessting, the problem is 9 is different from 10 - 16, it all because 9 is single digit. Then I check the data type settings for these variables. Here are what I found:
In SQL Server Agent job, the ApptsTime data was 'inserted' by @NewApptTimes, which is declared as char(5).In SQL Server database, the ApptsTime was defined as nvarchar(15).
My question are: 1. The reason why there were no 9 am data for the dataset, is becasue 9 am of nvarchar(15) is not > 8:30 of strApptPreTime? 2. If the answer to the quation 1 is yes, how do I define AppsTime and/or strApptPreTime?
TIA,Jeffrey
SqlCeParameter.Size Limited To 255 Characters For Char Types
Jul 10, 2007SqlCeParameter.Size seems to be limited to 255 characters for char types.
Eg.
SqlCeParameter param = new SqlCeParameter();
param.ParameterName = parameter_name;
param.DbType = DbType.String;
param.Size = 260;
Now check the value of param.Size, it will be 255.
In the past this problem was avoidable by setting the size to 0. However, this cause a problem if you are re-using the same command and simply changing the parameters value.
Somewhere the system remembers the length of the first value and adjusts the max size to be limited to this length.
Thus for the following values:
"Test"
"Testing"
The second one will error with something like "@param: String truncation: max = 4, len = 7, value = 'testing' "
Has anyone else come across this problem, or found a solution to it?
Char Vs Varchar
Dec 5, 2001Hi,
Does any body know of any performance implications of using 'varchar' data type against 'char'?
I have some columns that are using 'char' data type, but the data in them is not fixed length. So, to gain some disk space I am planning to change the data type to 'varchar'. But, I am concerned if there will be any performance de-gradation or any other implications of doing this.

CHAR Vs VARCHAR
Mar 26, 2001Hi,
Is that true that using CHAR datatype improves the performance comparing to VARCHAR
thanks
indeed.
VARCHAR Vs. CHAR
Oct 27, 2000Why would you want to use char when you have varchar? Is there any performance hit using a varchar and the size you make that varchar?
Debate going at work.

Varchar V Char
Feb 17, 1999I have recently inherited a database where all of the tables use varchar instead of chars for fields. Very , very few of these fields are involved in keys of even indices, but performance is an issue. I thought that I had read that varchars are worse for performance than chars when page splits may occur. Is this related to updates only, or does it matter?
Any help appreciated.
Char (8) Vs. Varchar (8)
May 8, 2006In relation to the code in this thread
http://forums.databasejournal.com/showthread.php?t=42622
My customer code field is Char (8) but accept an argument of Varchar (8) to my stored procedure. Don't ask me why!?!!
The customer code could be anything from 'A' to 'ZZZZZZZZ'.
Will this have any effect especially relating to overhead and retrieving incorrect data?
Char Vs Varchar
Feb 21, 2006Hi,
This question may sound silly,but please comment.
Please tell me a situation where char should be used and not varchar.
Let us assume that we are dealing with non unicode characters.
Well, I find varchar is always smarter than char, so why char?
Thanks!!

Varchar And Char
Feb 9, 2004i would like to know if there is an overhead in using VARCHAR when you use to store it...
a colleague of mine claims that if the field is defined to be VARCHAR the system creates and additional column DOUBLE/DECIMAL with storage size of 17/18bytes.
such that if the size of the varchar field is less than 30 it is better to be defined as CHAR instead.
please help me out here... i think there's something wrong with his statement, but i need concrete proof to it... a link to page or pdf file would be very much appreciated.
Char Vs. Varchar
Jul 23, 2005Greetings,I have a question. I work on some SQL2k/ASP.NET apps at work. Mypredacessor, who created the databases/tables seemed to have liked touse 'char' for all text fields. Is there a reason why he would havedone this over using varchar? It's a minor annoyance to always have toRTRIM data and it makes directly making changes to the database moreannoying (with all the pointless trailing spaces)?I usually use char for fixed string lengths, like state abbreviationsor something, and varchar for strings of unknown length.Is it a performance issue? Our database doesn't do much traffic, forthe most part.
