Hi All,
For €œnvarchar€? column if we pass the value as spaces, then it stores as space.
Eg:
declare @path nvarchar(50)
set @path = ' '
select '=>' + @path + '<='
Is there any setting / configuration that will force it to automatically trim the spaces and store it as null?
Thanks in Advance,
Palani
I'm trying desparately to write a PadRight function in SQL Server 2005. I seem to be failing miserably because the trailing spaces disappear when the data is returned. First of all, why does SQL Server think I want my string trimmed? And second, how do I overcome this? Code below:
Code Snippet
CREATE FUNCTION [dbo].[PadRight]
(
@sourceString NVARCHAR(4000),
@length INT,
@padCharacter NCHAR(1) = ' ',
@trimBeforePadding BIT = 1
)
RETURNS NVARCHAR(4000) AS
BEGIN
DECLARE @returnStringLength AS INT, @toReturn AS NVARCHAR(4000)
SET @toReturn = LEFT(@sourceString, @length)
IF @trimBeforePadding = 1
SET @toReturn = RTRIM(LTRIM(@toReturn))
SET @returnStringLength = LEN(@toReturn)
IF @returnStringLength < @length
SET @toReturn = @toReturn + REPLICATE(@padCharacter, @length - @returnStringLength)
RETURN @toReturn
END

I'm loading data from a sql server table into a flat file. The flat file connection manager has the following settings
GENERAL:
Format:Delimited
Text Qualifier:"
Header row delimiter: {CR}{LF}
Header rows to skip : 0
Columns:
Row Delimiter: {CR}{LF}
Column delimiter: comma(,)
If I run SELECT Len(' ') it returns 0, if SELECT Len('a ') it returns 1
I need this to return the correct length including the space that on the end. I thought it was an ansi_padding problem but even turning padding on results in a 0 length. Any ideas? Thanks!

Hi All... I'm using a SQL Server 2005 database. I've noticed that columns that are declared as "char" and that have a fixed size tend to put trailing spaces at the end of the data when I pull it out. I guess I can understand why... But it's a pain dealing with it. As I'm bringing my application up, I can see spaces all over the place - I just havent gotten around to doing anything about it yet. What's the easiest/best way to get rid of those spaces. Geez, it'd be real cool if I could put something in the SELECT statement. Any thoughts? Thanks much!! -- Curt
For some reason, there are extra trailing spaces being added to all my
data as it is placed in the db. I am collecting information from,
processing a TRIM-like function in javascript, and then again in the
ASP.net code before it is being placed in the db.
The extra spaces are causing problems with my application.
Any help would be greatly appreciated.
I have a column that is varchar(12) that the data was entered left justified
such as '12345 ' with trailing spaces. I need to move the number to be right justified to link with another table so it looks like ' 12345'. I looked at the right command and could not find a solution. An ideas?
Thanks

Problem is the col created to store result is varchar(1000) and can hold 1-3 values (loginIDs) per row with lots of trailing/white space.
E.g. (EmpID101, EmpID250 EmpID10)
Is there a technique to extract the needed value (loginIDs) from col?
Hello,when I export data from a table to a text file, I get trailing spacesif the data type in char. (This dosen't happen if the data type isvarchar). I can get rid of the spaces by using the trim() function onevery signle column. here is an example:DTSDestination("first_name") = DTSSource("last_name")My question is:Is there any easier way to get ride of the training spaces for allcolumns when exporing a table? It is too time consuming if I have totype trim() for every single column in the table.Thank you in advance,Eddy
View 1 Replies View RelatedI am trying to export data from a SQLServer database into a text fileusing a stored procedure. I want to be able to read it and debug iteasily; therefore, I want all the columns to indent nicely. This meansI need to append trailing spaces to a text string (such as "Test1 ")or append leading space in front of a text string that contains anumber (such as " 12.00"). Now, the stored procedure works fine whenI run it in Query Analyzer. But it doesn't work correctly when I runit using ISQL - All the columns are not indented. I am wondering whyit doesn't work in ISQL.This is what I want, and this is also what I get when I run the storedprocedure using Query Analyzer:Test1 , 2,Test1.txt , 1.00, 1.00Test22 , 2,Test22.txt , ,Test333 , 2,Test333.txt , 30.00, 30.00This is what I get if I run the stored procedure using ISQL(isql -S myserver -E -w 556 -h-1 -n -d mydb -Q "exec MyTest"):Test1, 2,Test1.txt, 1.00, 1.00Test22, 2,Test22.txt, ,Test333, 2,Test333.txt, 30.00, 30.00You can see that the result from ISQL has the following differences:1. It puts a space in front of each row.2. It appends enough spaces at the end of each line to makethe line length to be exactly 61 characters.3. It gets rid of the trailing space from each column.4. It leaves only one blank space if the column has nothingbut a serie of spaces.The following is the stored procedure that I am testing:create procedure MyTestasset nocount oncreate table #Test(Field1 varchar(10) null,Field2 varchar( 5) null,Field3 varchar(20) null,Field4 varchar(10) null,Field5 varchar(10) null)insert into #Test values( "Test1 ", " 2","Test1.txt ", " 1.00", " 1.00" )insert into #Test values( "Test22 ", " 2","Test22.txt ", " ", " " )insert into #Test values( "Test333 ", " 2","Test333.txt ", " 30.00", " 30.00" )select Field1 + "," +Field2 + "," +Field3 + "," +Field4 + "," +Field5from #Testdrop table #TestgoStrangely, the differences #3 and #4 only show up when I use theSELECT statement on a table. They don't show up when I use SELECTstatements to show constant text strings or string variables, likethis:set nocount onselect "Test1 " + "," +" 2" + "," +"Test1.txt " + "," +" 1.00" + "," +" 1.00"select "Test22 " + "," +" 2" + "," +"Test22.txt " + "," +" " + "," +" "select "Test333 " + "," +" 2" + "," +"Test333.txt " + "," +" 30.00" + "," +" 30.00"The result is like the following if I use constant text strings orstring variables:Test1 , 2,Test1.txt , 1.00, 1.00Test22 , 2,Test22.txt , ,Test333 , 2,Test333.txt , 30.00, 30.00I need to run it from ISQL because that is how I run _all_ my otherstored procedures. I don't want to do anything differently justbecause I need to run this stored procedure.Thanks in advance for any suggestion.Jay Chan

Hi
Is there any way to trim all the leading and trailing spaces in all the column in a table.
JigJan
Hi All,
I have a column which has some white spaces that I suspect is tab delimeted one. So when I use a rtrim(col1) it would not trim those. So i used a scrip component and wrote this line,
Row.trimDetail = RTrim(Row.detail)
here trimdetail is an o/p column and detail is the input col with the trailing spaces.
but still I don know why the column has that spaces. Can someone help me to figure out what is the problem ?
Thanks in advance,
I am trying to pad a fixed number of trailing spaces into a report expression, as follows:
Data:
CUSTOMER_NAME-------------MichaelPeterJohn
Result (e.g. with 10 spaces padded, assuming all names are below 10 characters long):

Is there an easy way to achieve this ?
Thanks.

Hi, I'm inserting a few columns into my db (they all have a nvarchar(50) ).. but i noticed when i retrieve them out of the db, the length of the string always have some trailing white spaces behind them and such when I try to do stuff like dropdownlist.items.findbyvalue(), it normally fails.I did trace and before the string get into the db, they were teh right length. so I'm not sure where did I do things wrong? thanks

I am using asp.net 2.0 and SQL serer 2005 reporting services.
Hello Everyone,
I've seen many entries about trailing spaces but have not found one like this.
In the Control Flow I am using an "Execute SQL Task" to populate some SSIS local variables (type string) by: (1) executing a SQL stored proc with output variables (type varchar(100)) to (2) be mapped to the local variable name (the parameter mapping Data Type is VARCHAR).
One of these mapped outputs is used as a path for subsequent operation in the Control Flow. At execution the sproc fires, populating the local variable with the path but with trailing spaces out to 255. Later in the "Script Task" when that path is used I receive an error telling me that the path is too long, and something about 260 or 246 characters.
Here's the oddity. I have two desktop environments running XP and a server environment (server 2003). This package runs just fine on the server - no trailing space issue, no need to trim. But on both my desktops I get the errors. By adding trim statements I can get back the correct path, but varchars should not be including trailing spaces, and the sproc return variable is a varchar (100).
I know this soulds like numerous other posts which indicate the solution is to trim, but I think the question I am asking is why does it work on the server but not the desktop? Is the SSIS variable type string experiencing a bug on different OS's?
Not to further complicate the issue but it used to work on my laptop, but through a horrible sequence of events I had to reload the studio in which case the error started to happen on that too.
I am loading data using SSIS 2008 from a table in SQL Server 2008 DB to excel 97 sheet pre-defined with column headers. All the columns in excel is has 'Text' format property and the columns in the SQL Server table are defined as nVarchar. One of the columns has trailing spaces in few rows in DB but after exporting to excel 97, the spaces are gone. We need to retain the whitespaces in the column values. How can we do that.
View 3 Replies View RelatedHello,This is a simple question, hopefully with a simple answer. I havean nvarchar column of length 255. In one of the rows I have thefollowing sentance - 'See the brown ball bounce'. Is it possible touse a command to remove all of the spaces in that sentance, so thatthe sentance reads 'Seethebrownballbounce'? As you can see, I am notjust interested in getting rid of the trailing and leading spaces.Thanks,Billy

I have a databound textbox that is used to store a decimal value.
If my sql table stores this column as a decimal(2,2), then all of the numbers entered into the field will automatically put decimal places in that I don't want. For example, 45 becomes 45.00... 34.5 becomes 34.50.
If I set the sql table to nchar(10) and the dataset to system.string (max length of -1), then the number looks the way I would like it, however after a datatable update I end up with trailing whitespace after the number - filling up the rest of the unused 10 characters. For example, "45" becomes "45 " (8 spaces afterwards).
Does anybody know how I can fix this? I would prefer to store the numbers in SQL as a string (nchar(10))... but I don't know how to get rid of that darned whitespace. I would like to remove it at the database level and not at the client level if at all possible.
Thanks!

View 2 Replies View RelatedHi all,I need to store data into about 104 columns. This is problematic with MSSQL, since it doesn't support rows over 8kb in total size.Most of the columns are of type NVARCHAR(255), which means we can't havemore than 8092/(255*2) = 15 columns of this type.With a row length of more than 8kb, SQL gives a warning that any rows overthat amount will be truncated.So far I'm seeing two possible solutions to this problem:1. Split data into multiple tables with the same ID column accross alltables, and then join them on SELECT statements.2. Use NTEXT instead of NVARCHAR. NTEXT's length is 16 bytes because itcontains a pointer to the actual value stored somewhere else. However, NTEXTdoesn't support regular indexing, only through a Full-Text Index catalog. Inthis case I'll need to user "WHERE CONTAINS(columnName, 'sometext')" toperform searches, which is bearable.I'm inclined toward #2. However I haven't used Full-Text indices before anddon't know their limitations. Will I run into problems with NTEXT? Is therea better solution?Thanks.-Oleg.

View 4 Replies View RelatedI know that if I have an nvarchar column I can use an equality like = N'supersqlstring' so it doesn't implicit cast as a varchar, like if I were to do ='supersqlstring'. And then I'll be a big SQL hero and all my stored procedures will run before a millisecond can whisper.
But if I'm comparing an nvarchar column to a varchar column, is it better to cast the varchar 'up' to an nvarchar or cast the nvarchar 'down' to a varchar?
For instance:
cast(a.varchar as nvarchar(100)) = an.nvarchar
or
cast(an.nvarchar as varchar(100)) = a.varchar
Leaving aside non-matching, like (at least I don't think) that SQL considers the varchar n to be equal to the nvarchar Å„, what's the best way to handle this?
Pretend for a moment that each column contains a mixed letter and number ID with no accented or wiggly-squiggly Unicode characters; it's just designs clashing.
Is there a performance hitch doing it one way or another? Should I use COLLATE? Should one of the columns be altered?
I have an issue where I am storing various international characters in nvarchar columns, but need to branch the data at one point of processing so that ASCII characters are run through an additional cleansing process and all non-ASCII characters are set aside.
Is there a way to identify which nvarchar values are within the ASCII range and can be converted to varchar without corruption? Also, the strings may contain a mix of english and international character sets, so the entire string must be checked and not just the first character.
i.e.
Pass:
'Hello', 'abc123'
Fail:
'太平市', 'abc太123'
Hi ,
My Input is a flat file source and it has spaces in few columns in the data . These columns are linked to another table as a foreign key and when i try loading them in a relational structure Foreigh key violation is occuring , is there a standard method to replace these spaces .
what approach should i take so that data gets loaded in a relational structure.
for example
Name Age Salary Address
dsds 23 fghghgh
Salary description level
2345 nnncncn 4
here salary is used in this example , the datatype is char in real scenario
what approach should i take to load the data in with cleansing the spaces in ssis

I had this question for quite a long time.
It seems the latter one don't take any extra storage space than the previous one.
As long as the real string length is less than 10.
Is that mean the latter one not cost anything?
I once heard the different is when they are in memory. But not sure of it.
Can anyone explain it and provide some official reference on it?
Thank.
