How Do I Exclude Carriage Returns As Part Of A IS NULL Exclusion Clause...
Jan 6, 2005
Hi
I have stupid users... who doesn't?! They have entered carriage returns as a whole value in some fields, that is, the field contains nothing more than a carriage return.
I really need to treat these cases as nulls and have successfully removed whole fields of nothing but spaces by using the LTRIM(RTRIM()) construct. Unfortunately, this doesn't deal with carraige returns. Even CASTing and CONVERTing to varchar and then using LTRIM(RTRIM()) doesn't work.
Does anyone know how I can elegantly get around this problem other than my best guess below:
Best guess pseudo code:
IF count of field is greater than 1 THEN probably a full sentence so ignore ELSE SUBSTRING first character and if CHAR(10, etc) then treat as NULL.
Here's some code that reconstructs the problem:
select datalength(char(13)) CarriageReturnVisible
, datalength(ltrim(rtrim(cast(char(13) as varchar)))) [This Don't Work]
Cheers - Andy

hello,
could any one tell how to go about keeping carriage returns and line breaks when inserting a chunk of text so that when that text is recieved it will still contain those carriage returns and line breaks?

I'm using Microsoft SQL 2005.
I am attempting to store text in a column defined as varchar(2048). The text contains line feed and carriage return characters. After examining the database column the text is truncated after the first set of line feed and carriage return characters.
Is there a way to force SQL Server to store these characters?
Much Thanks, Robert

Can anyone provide me with some SQL that will identify rows from a table where a varchar column named "Notes" contain Carriage Returns?
I know that with report writer SQR I can translate CR's to white space but I do not know of any Sybase function that will allow me to do the same, any ideas on this well would be appreciated.

I have a report which has multiple fields in the same column of a table. So that it formats correctly, on the stored procedure side I inserted char(10) + char(13). This allows the next field to correctly carriage return on the report. The report looks great.
But once the report is exported to MS Excel, it appears to add in extra carriage returns. This can be cleaned up by going record by record and back-spacing over the carriage returns.
Is there any other work around for this?
Just curious. Thank you for your help.

Hi all,I have an old ASP .NET 1.1 application that I haven't had time to rebuild with .NET 2.0. No changes have been made to the application or the SQL Server the application uses. I have a web form where users can type multiple lines of text, and it is entered into an SQL database (SQL 2000 Enterprise) into a column with a datatype of "text". Recently (it seems out of nowhere), If my users enter a carriage return into the webform, it becomes a question mark in the sql database. It's really a bit funny, but also annoying, lol. Does anyone have any idea why this might be happening? Thanks so much!

I am migrating from 2000 to 2005 and in the process of rewriting DTS to SSIS. So far so good.
I have an import of a flat file that I need to reproduce that works fine in DTS but throws SSIS.
The file contains details of products, and has a Long Description field that may contain lots of different chars - CR & LF amongst them. It's source and destination columns are Text type.
The file is tab delimited, text delimited with double quotes, with row delimiters of CRLF and column names on row 1.
The error SSIS throws is "The column delimiter for column "LongDescription" was not found"
I imagine (perhaps wrongly) that this is because of the extra CRLFs but it worked fine in DTS. It also previews fine, and lets me define the column properties OK in SSIS package designer.
Any help greatly appreciated. I am trying to avoid the obvious thing of replacing those chars in that field at this point as currently the export is shared between a live production server, and my test 2005 rig.
Thanks v much.
Chris.

In SSRS/RDL, How do you format a column heading to use carriage returns?
I have a couple of instance where I have a column heading that I want spread over 3 lines. For example, the column heading "= Actual Amount" I would want centered and displayed on 3 lines, as follows:
=
Actual
Amount

Hello,
I have a TSQL (SQL SERVER 2005) code inside a Transaction,
I would like to exclude a piece of that code from the transaction (I do need to recovere it in the trasaction log).
For instance
BEGIN TRAN
SQL Statement 1
SQL Statement 2 -- out of the transaction
SQL Statement 3
COMMIT TRAN
I would like to exlude SQL Statement 2 (SQL statement1 and 3 must be inside the same transaction)
Is it possible? How to do it?
Thank

I'm trying to import a flat file source into a SQL Server table.
The flat file is pipe-delimited and text qualified with " (double-quotes).
The import job is failing because there is a "comments" field in the flat file and there are carriage returns within some records in the "comments" field. When SSIS encounters a record with a carriage return within that field, it sees the carriage return and assumes the end of the record, even though the field is text qualified with " ".
The actual error message I see is: "
Error 0xc0202055: Data Flow Task 1: The column delimiter for column "comments" was not found.
(SQL Server Import and Export Wizard)
Sample Record:
"418186"|"94"|"Staff Only-Minimum charge out of 3 hours
Plus travel & accommodation costs (if required) – at cost.
All trauma response services & associated fees/costs are required to be formally authorised by the Company prior to delivery."|""|"690"|""
I can't think of a way to get SSIS to ignore the carriage returns within the Comments field in the source flat file!

Hello.
I've built a sample CLR function with the following declaration....
CREATE FUNCTION GetManager(@DeptCode nvarchar(3))
RETURNS nvarchar(1000)
WITH RETURNS NULL ON NULL INPUT
AS
EXTERNAL NAME Assembly1.[ClassLibrary1.MyVBClass].MyManager
And it works as expected, except when I use NULL:
DECLARE @MyManager nvarchar(1000)
EXEC @MyManager = dbo.GetManager NULL
PRINT @MyManager
It returns the value "Unknown" as it would have for any unknown DeptCode, as-programmed.
I'm of the theory it should have returned NULL without actually firing the function? Or is this only for non-CLR items... or stored procedures, not functions?

I have some data from SQL server which contains NULL values for certain fields. I have to create a chart with sum of a field. There is no category and series groups, we are just showing the total sum of a field in chart. Since I have NULL in my source data, nothing is displayed in the chart. I cannot exclude this record from dataset as I have to use this record for other charts. I have to do some filtering in the chart area itself. I have given IsNothing() in the filter of chart properties. It does not work for me. Even I tried to give IsNothing() in the exp of Sum() .

Hi all,
is it possible to exclude empty records from an ADSI QuerySelect?
I got a query like
Code SnippetSELECT objectGUID FROM OpenQuery(ADSI, 'SELECT objectGUID FROM ''LDAP://DC=whatever,DC=domain,DC=org'' where objectClass = ''User'' AND objectCategory = ''Person''')
and would like to have it like
Code Snippet
SELECT objectGUID FROM OpenQuery(ADSI, 'SELECT objectGUID FROM ''LDAP://DC=whatever,DC=domain,DC=org'' where objectClass = ''User'' AND objectCategory = ''Person'' AND homeDirectory IS NOT NULL')
or
Code SnippetSELECT objectGUID FROM OpenQuery(ADSI, 'SELECT objectGUID FROM ''LDAP://DC=whatever,DC=domain,DC=org'' where objectClass = ''User'' AND objectCategory = ''Person'' AND NOT(homeDirectory = NULL) ')
The problem is that I can only perform a query like
Code SnippetSELECT objectGUID FROM OpenQuery(ADSI, 'SELECT objectGUID FROM ''LDAP://DC=whatever,DC=domain,DC=org'' where objectClass = ''User'' AND objectCategory = ''Person'' AND NOT(homeDirectory = '''')')
which results in the error
"Could not fetch a row from OLE DB provider 'ADSDSOObject'."
There are many objects which do have a homedirectory, though, and therefore should be fetched.
Any comments or hints on where my error hides?
I know I could go on fetching all objects and exclude the unwanted ones later on but I'd simply run into the limitation of data records LDAP would provide me with.
Thanks in advance!
Regards,
caracol

I havethe following query which returns one row of data, however, the MedicalcodeID is NULL.
SELECT db1.dbo.Referral.ReferralGuidDigest, dbo.patient.PatientID, dbo.Consultation.ConsultationID, dbo.Staff.StaffID,

[code]...
It is clear from teh above - that the expected MedicalCodeID = 33959 and NOT NULL. I dont understand why SQL added the COLLATE SQL_Latin1_General_CP1_CS_AS to the query - am working on a database developed by another person. Could it be the ACode and ReadCode in dbo.lkupMedical is not set up with SQL_Latin1_General_CP1_CS_AS. How to implement to LkupMedical table....
I changed HIGHLIGHTED JOIN to Inner/Right but it never yielded any results, no record found..

Hi,
we are facing some issue to get the underlying OledbConnection from the runtime ConnectionManager.
below is the code sample that we are using
IDtsConnectionService conService = (IDtsConnectionService)this.serviceProvider.GetService(typeof(IDtsConnectionService));
if (conService == null)
return;
ArrayList conCollection = conService.GetConnectionsOfType("OLEDB");
for (int count = 0; count < conCollection.Count; count++)
{
string conName = ((ConnectionManager)conCollection[count]).Name;
if (conName == conMgrname)
{
conMgr = DtsConvert.ToConnectionManager90((ConnectionManager)conCollection[count]);
ConnectionManager cm = DtsConvert.ToConnectionManager(conMgr);
Microsoft.SqlServer.Dts.Runtime.Wrapper.ConnectionManagerAdoNet cmado = cm.InnerObject as Microsoft.SqlServer.Dts.Runtime.Wrapper.ConnectionManagerAdoNet;
OleDbConnection conn= cmado.AcquireConnection(null) as OleDbConnection;
}
}
In the sample above the conn is null.
To this query Darren replied to use the connection of type ADO.NET:System.Data.OleDb.OleDbConnection, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 to create the connection.
Your call to GetConnectionsOfType("OLEDB"); will return native OLE-DB connections, not ADO.NET connections, using the OleDbConnection.
The connection type for the ADo>NET OLE-DB connection is -
ADO.NET:System.Data.OleDb.OleDbConnection, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
but if user creates an New OLEDB Connection from the Connection Manager panel of the BIDS and selects the same from the custom UI how to get the underlying OLEDBConnection? the CreationName in this case is "OLEDB" and not ADO.NET:System.Data.OleDb.OleDbConnection, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089.

I find it weird when decrypting a column from a baked up database and restoring it to another database. Here's the scenario:
Server1 has Database1.
Database1 has Table1 with two columns encyrpted -- Card Number and SS Number
Encryption and decryption in this Database1 is perfectly fine. Records are encrypted and can be decrypted too.
Now, I tried to backup this Database1 and restore it to another server with SQL 2005 instance called Server2. Of course the columns Card and SS Numbers were encrypted. I tried decrypting the columns using the same command to decrypt in Database1, however, it returns a NULL value
Here's exactly what I did to create the encyprtion and decryption keys on the restored database:
-- Create the master key encryption
CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'myMasterPassword'
-- Create a symetric key
CREATE SYMMETRIC KEY myKey WITH ALGORITHM = DES
ENCRYPTION BY Password='myPassword';
Go
-- Create Card Certificate
CREATE CERTIFICATE myCert WITH SUBJECT = 'My Certificate on this Server';
GO
-- Change symmetric key
OPEN SYMMETRIC KEY myKey DECRYPTION BY PASSWORD = 'myPassword';
-- I then verified if the key is opened
SELECT * FROM sys.openkeys
If I create a new database, say Database2 from that Server2, create table, master key, certificate, and symmetric key. Encrpytion and decryption on Database2 will work!
Any suggestions gurus? I tried all searches and help for almost 2 weeks regarding this issue but nobody could resolve this.
Thanks in advance!

I have a SQL 2005 clustered server which is returning a Null value for @@servername. I find the server entry in sysservers. I have replication configured on this so i am not able to do a Sp_dropserver & sp_addserver as this acts as a publisher. The configured merge repication stopped working because of this issue and I am not able to delete replication as the the delete option uses @@servername which returns a null value. So I am struck in a loop.
Any advice is appreciated.

Hi folks,I have an issue with a column I created in my query called Instance.SELECT Object_Id, Event_type, Audience, Subject, Provider, Academic_Year, Start_date, End_date, CONVERT(varchar, Academic_Year) + ' (' + CONVERT(varchar, Start_date, 103) + ') : ' + Event_type AS InstanceFROM EventsORDER BY Event_type Above is my query. The problem is because the start date column can be null, it also returns the Instance column as null for that row.I thought it would have just missed out the date and display the rest, but it doesn't.Is there any way I could get the Instance column to display a value, when the start date is null?ThanksEdit: Managed to sort it using ISNULL()

Hi All,
I have a built an application to manage the report-subscription on my ReportServer.
I'm having some troubles with retrieving the subscription properties.
My problem:
I can retrieve all my propertie except the schedule definition, when I deserialize it, the Sceduledefenition.Item always returns null.
I use the next code to deserialize it:
//////////////////////////////////////////////////////////////////////////////////////////////////////
private XmlAttributeOverrides GetSchedule()
{
XmlAttributeOverrides xmlAttrOverride = new XmlAttributeOverrides();
XmlAttributes XmlAttr = new XmlAttributes();
XmlAttr.Xmlns = false;
xmlAttrOverride.Add(typeof(ScheduleDefinition), XmlAttr);
xmlAttrOverride.Add(typeof(MinuteRecurrence), XmlAttr);
xmlAttrOverride.Add(typeof(DailyRecurrence), XmlAttr);
xmlAttrOverride.Add(typeof(WeeklyRecurrence), XmlAttr);
xmlAttrOverride.Add(typeof(MonthlyRecurrence), XmlAttr);
xmlAttrOverride.Add(typeof(MonthlyDOWRecurrence), XmlAttr);
xmlAttrOverride.Add(typeof(DaysOfWeekSelector), XmlAttr);
xmlAttrOverride.Add(typeof(MonthsOfYearSelector), XmlAttr);
return xmlAttrOverride;
}
private ScheduleDefinition DeserializeScheduleDefenition(string MatchData)
{
XmlAttributeOverrides xmlAttrOverride = GetSchedule();
XmlSerializer ser = new XmlSerializer(typeof(ScheduleDefinition),xmlAttrOverride);
Stream stream = new MemoryStream(System.Text.Encoding.Default.GetBytes(MatchData));
stream.Position = 0;
return (ScheduleDefinition)ser.Deserialize(stream);
}
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
I'have tried almost everything, but could not find the solution.
Please, this is very important for me, so every tip or shared thought could be very helpfull.
Thnx in advance

How do you prevent SQL from returning a null value for a computed column?
The following formula returns blank if any of the values are blank ... pftitle allows nulls, the other two are required on Insert.
(((([pflastname]+', ')+[pffirstname])+' - ')+[pftitle])
Where can I find the documentation of computed field operators and expressions?

Im having some unexpected results from combining ISNULL with logical and '&&' and conditions '?:' in derived columns.
This works and returns A or B.
(ISNULL(Col1) && Col2 == "X") ? "A" : "B"
This fails returning Null when Col1 is null
(Col2 == "X" && ISNULL(Col1)) ? "A" : "B"
This fails returning null when Col1 is null
(ISNULL(Col1) && Col2 == "X") ? "A" : (ISNULL(Col1) && Col2 == "Y") ? "B" : "C"
I've applied service pack one and still have the issue. I've also tried using ISNULL in a condion like (ISNULL(Col1) ? TRUE : FALSE)
Anyone else seen this behavior?
