I wrote a simple data flow with an OLE DB source and destination. I do a direct mapping of the columns ( colA - > colA) with no transformations needed. I found that colA on the destinatin does not allow NULLS (required by the program that accesses that database) while colA on the source supports and has NULLs, Is there any accomodaiton for handling NULLS (like mapping them to blanks) in the direct copy approach or do I need to read each row and test colA_ISNull?
TIA,

Quick Question I hope.
Does having a lot of blanks in a column cause errors ?
In 2 or 3 packages where I get 95% of the data in the Error Colomn I can find nothing wrong with the data at all ? it all either seems perfect or there is no data in the column in question usually I would have maybe 800 rows where data would have been inserted but in the other 40, 000 rows the column is blank
Using the "Retain null values from the source as null values in the destination" doesnt seem to make a differance.
This is the error description
The data value cannot be converted for reasons other than sign mismatch or data overflow.
Anyone know of a solution / reason why this keeps happening
Thanks

I posted this scenario earlier and ndinakar said my code worked on (I guess) his own machine but has not worked on mine! Does that not sound funny? I need to ge through with this simple but frustrating stuff in time. I've implemented more complex snippets before this but I just can't figure the problem out.
Can anyone out there tell me what I could be doing wrongly? I wrote a simple stored procedure called 'proc_insert_webuser' in a database that has been moved to a remote server called LAGOS-NTS3. I executed it from SQL Query Analyser and it worked. When, however, I executed the same stored procedure from ASP.Net it gives an impression that a new record has been inserted and even displays the newly generated ID column to me. On checking the base table I found only blank columns with only the ID column having the generated IDs!
I'm perplexed. I checked the code and can't possibly spot the error. Can anyone help. Found below are snippets used.
CREATE PROCEDURE proc_insert_webuser
(
@applicantidnumeric(18) output,
@firstnamevarchar(18),
@midname varchar(18),
@lastname varchar(50),
@secretcodevarchar(18),
@my_errnumeric(18) output
)
AS
IF (SELECT COUNT(ApplicantID) FROM tbl_webuser WHERE Firstname = @firstname AND Midname = @midname AND Lastname = @lastname) = 0
BEGIN
begin transaction
INSERT INTO tbl_webuser (Firstname, Midname, Lastname, SecretCode)
VALUES (@Firstname, @Midname, @Lastname, @SecretCode)
commit transaction
SET @applicantid = @@IDENTITY
END
ELSE
BEGIN
RAISERROR('Error! Execution aborted. A matching user profile exist.', 16, 1)
SELECT @my_err = @@ERROR
END
RETURN
Then the ASP.Net stuff:
Sub PostData()
'connection string production
Dim cstring As String = "User ID = sa; Password = ; database = E-Recruitment; Server = LAGOS-NTS3; Connect Timeout = 60"
'connection instantiation
Dim cnx As SqlConnection = New SqlConnection(cstring)
Try
'open connection
cnx.Open()
'instantiates and execute a command object
Dim cmd As SqlCommand = New SqlCommand
With cmd
.Connection = cnx
.CommandText = "proc_insert_webuser"
.CommandType = CommandType.StoredProcedure
Dim param1 As New SqlClient.SqlParameter("@applicantid", 0)
param1.DbType = DbType.Single
param1.Direction = ParameterDirection.Output
.Parameters.Add(param1)
Dim param2 As New SqlClient.SqlParameter("@firstname", txtFirstNM.Text)
param2.DbType = DbType.String
param2.Direction = ParameterDirection.Input
.Parameters.Add(param2)
Dim param3 As New SqlClient.SqlParameter("@midname", txtMidNM.Text)
param3.DbType = DbType.String
param3.Direction = ParameterDirection.Input
.Parameters.Add(param3)
Dim param4 As New SqlClient.SqlParameter("@lastname", txtLastNM.Text)
param4.DbType = DbType.String
param4.Direction = ParameterDirection.Input
.Parameters.Add(param4)
Dim param5 As New SqlClient.SqlParameter("@secretcode", txtPWD.Text)
param5.DbType = DbType.String
param5.Direction = ParameterDirection.Input
.Parameters.Add(param5)
Dim param6 As New SqlClient.SqlParameter("@my_err", 0)
param6.DbType = DbType.Single
param6.Direction = ParameterDirection.Output
.Parameters.Add(param6)
.ExecuteNonQuery()
'pick the auto-number
Dim strAppID = .Parameters("@applicantid").Value
'notifies the user of record success
lblMessage.Text = "Profile created. Your ApplicantID is : " & strAppID & " Kindly take note of your UserID. You'll need it for future logins."
End With
Catch ex As Exception
'notifies the user of any error(s)
lblMessage.Text = Err.Description & " originating from " & Err.Source
Finally
cnx.Close()
End Try
End Sub
==================
I'm calling this procedure from the click event of a command button. What could be happening to the code? I have done similar things and got positive results! Any hint from anyone out there?

Hi,
I'm trying to create a view from a table in which I want to concatenate to columns to a new column. The concatenation part works fine when data "supports" calculations, i.e. no nulls. The data however is "infected" in two ways I have Null-values and I have blanks alongside with some real information. I concatenate via a CASE statement but I can't figure out how to take the 3 situations into account (nulls, blanks and data) and create one meaningfull column in my view.
The result should be
column1 + "-" if column2 is null or blank
column1 + "-" + column2 if column2 has meaningfull data
Both the involved columns are text (varchar).
If anyone has been in this situation before could you please provide som code that handles the situation.
Regards
Kim Hansen

Hello,
In my .NET.ASP application I generate a random five digit password, like so:
string password = Membership.GeneratePassword(5, 1);
The result could be a password like "0l$IE" and I the save this password to an SQL server. The problem is however that with the generated password five blanks are also added. Instead of "0l$IE" I get "0l$IE ". I hope you understand what I mean? Is there an easy way to correct this?
I appreciate any help!

I have an Excel spreadsheet with a field that may contain blanks (empty). When I filter on that field to show only the blanks, I get 4000 records returned. But if I import the spreadsheet into SQL Server, the test in there for blanks ('') returns nothing. However, if I test for Nulls in that field, I get 5000 records returned. I don't know which one (Excel or SQL Server) is giving me the right answer. Can anyone help me understand what's going on?
Thanks!

I have a comma delimited data file TestData.txt of the form:
123,asss,aweqrrr ,ssdsff , ,2wwwrwrr
434,sff,dgfdgd ,sffsfsfete ,sd ,dff
I want to load this data into SQL Server tables so that the data will be imported without the trailing spaces(blanks) after each data element .
Thus I will like to trim the data of the extra spaces (blanks) before import.
Desired data to be loaded :
123,asss,aweqrrr,ssdsff,,2wwwrwrr
434,sff,dgfdgd,sffsfsfete,sd,dff
Any help will be most welcomed

I am looking for a query which will populate one of my columns that contains some blanks with a defined value based on a value in another column
For example in the below table I would like the blanks in serial number to be populated with "SN09"
Product_NameSerial_Number
PRODUCT1
PRODUCT1
PRODUCT2SN10
PRODUCT3SN11
PRODUCT3SN11
PRODUCT1
So the query I am looking for would basically add some values to the results where they meet the right criteria.
I am running the query through a view so I dont actually want to add the values to the physical tables only to the view of the results if you understand what I mean?

Hi,
I am having a curious problem with parameter passing between
reports. I have 2 reports the first report gives employee name, Department and
in the second report I have employee details. If the user clicks on the
Employee name in the First report it should go to the second report and display
the details. My problem comes if suppose the employee name is Don King? when the parameter gets passed it does not recognize
the space between the name and throws
an error saying King not recognized.
Would appreciate if anybody could suggest as to how I can
pass the name with spaces in the report parameters.
Thanks and regards

Hi,
With DTS, the default behavior is to import blanks ("") in a data file as nulls in the table.
However, in SSIS, the default behavior is to import blanks as blanks.
I need to ensure that the packages I'm migrating import the data in the exact same way. I am wondering what is the easiest way to convert blanks to nulls?
Right now I'm using a script to convert the blanks to nulls before they are written to the table, but just wondering if there's an easier way.
Thanks

I have a report that has DateTime parameters e.g. StartDate and EndDate. When I create these report parameters the "Allow Blank" option is disabled but checked. When I run the report and do not enter anything in these fields it pops a message asking me to enter the Date. How do I use the "Allow Blank" option for date parameters on my report?

I'm working on a new project using SSIS in SQL Server 2005 and have an issue that I need resolved.
I'm loading an XML file into SSIS using the XML Source Adapter. This maps to an OLE DB destination which reads the data into a SQL table (please see below for the table structure). In between this stage is a data conversion to convert the Unicode characters from XML into non-Unicode characters.
CREATE TABLE [dbo].[XMLTest](
[Forename] [varchar](50) COLLATE Latin1_General_CI_AS NULL,
[Surname] [varchar](50) COLLATE Latin1_General_CI_AS NULL,
[PostCode] [varchar](50) COLLATE Latin1_General_CI_AS NOT NULL
)
The problem I have is with blank strings in xml are being inserted into the SQL table as NULL values and not blanks (see the xml below).
<Root>
<People>
<Forename>Duncan3</Forename>
<Surname></Surname>
<PostCode>ME16 0WH</PostCode>
</People>
</Root>
Correct me if I'm wrong but a null value in xml means the node does not exist (See the xml below)?
<Root>
<People>
<Forename>Duncan3</Forename>
<PostCode>ME16 0WH</PostCode>
</People>
</Root>
Please also find the schema attached for reference.
<?xml version="1.0"?>
<xschema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">

Hi,
This might sound obvious, or a newbie question, but how are trailing blanks treated by SQL2005 on varchar columns?
I have a column where two rows only differ by a trailing blank. If write a select and a where clause on the column, anly trailing blanks seem to be trimmed. I tried the ansi padding setting but it doesn't change anything. Is it a question of collation? I have default collation on the server set to SQL_Latin1_General_CP1_CI_AS...
The problem also seems to arise when I try to create a unique index on the column, where both values are considered equivalent...
I give here a sample based on the BOL for set ansi_padding. I was expecting each of the select statements below to retrun only one row...
Cany somebody please explain why they all return two rows?
PRINT 'Testing with ANSI_PADDING ON'
SET ANSI_PADDING ON;
GO
CREATE TABLE t1 (
charcol CHAR(16) NULL,
varcharcol VARCHAR(16) NULL,
varbinarycol VARBINARY(8)
);
GO
INSERT INTO t1 VALUES ('No blanks', 'No blanks', 0x00ee);
INSERT INTO t1 VALUES ('Trailing blank ', 'Trailing blank ', 0x00ee00);
INSERT INTO t1 VALUES ('Trailing blank ', 'Trailing blank', 0x00ee00);
SELECT 'CHAR' = '>' + charcol + '<', 'VARCHAR'='>' + varcharcol + '<',
varbinarycol
FROM t1
where varcharcol='Trailing blank';
GO
SELECT 'CHAR' = '>' + charcol + '<', 'VARCHAR'='>' + varcharcol + '<',
varbinarycol
FROM t1
where varcharcol='Trailing blank ';
GO
PRINT 'Testing with ANSI_PADDING OFF';
SET ANSI_PADDING OFF;
GO
CREATE TABLE t2 (
charcol CHAR(16) NULL,
varcharcol VARCHAR(16) NULL,
varbinarycol VARBINARY(8)
);
GO
INSERT INTO t2 VALUES ('No blanks', 'No blanks', 0x00ee);
INSERT INTO t2 VALUES ('Trailing blank ', 'Trailing blank ', 0x00ee00);
INSERT INTO t2 VALUES ('Trailing blank ', 'Trailing blank', 0x00ee00);
SELECT 'CHAR' = '>' + charcol + '<', 'VARCHAR'='>' + varcharcol + '<',
varbinarycol
FROM t2
where varcharcol='Trailing blank';
GO
SELECT 'CHAR' = '>' + charcol + '<', 'VARCHAR'='>' + varcharcol + '<',
varbinarycol
FROM t2
where varcharcol='Trailing blank ';
GO
DROP TABLE t1

Can someone please point me in the right direction on this problem. The report will run sometimes, but most of the time it will not.

Hi i have 2 cols
col1 col2
A1 21
A2 22
A3 21
A4 23
I want to create a report such that i should see all values of col1 but in col2 i want to show only value of 21 and the remaining should be zero.
So basically all the other values except 21 should be zero in the report but should not be updated in the database.
So the report should look like
col1 col2
A1 21
A2 0
A3 21
A4 0
can you please tell me how to do that

Hi,Is it possible to do from one script? We have a set of user's tables like"tbl%". We can get this list very easy using this script:SELECT name FROM sysobjects WHERE xtype = 'U' AND name LIKE 'tbl%' ORDER BYname;We need to change some column names if these names are in a special listthat we have. What can we do? Use FOR EACH ROW? Or what?So, I need to get a column list for each table and check if every columnname is equal to one of the names from the list and then if YES replace itby something or add some symbol to this name. Terrible or possible?Regards,Dmitri

Hi all,
We are trying to migrate a SQL Server 2005 database/schema onto SQL CE. The original SQL Server 2005 schema uses views. And VIEWs are not supported on SQL CE. What can we use as an alternative?
Here are the option I can think of:
Use Tables instead of views : We are currently using this approach. But the disadvantage is that data remains on the DB. We need to clean and reuse the table everytimeCan we use a DataSet or DataTable instead? Any sample code available?
Can we replace them by some in-memory data structure?

Hi,
I would like to replace all instances of a code that starts with 'GEM' with the word 'Perfect'', and all instances of the code that starts with 'GOLD' replaced with 'Imperfect'.
For example, if I have a table named STONES, and a field within the table STONES.Code contained codes such as 'GEMPART4000', 'GEMPART5000', 'GOLDSIDE2300' and 'GOLDSIDE3000', I want to return the first two codes as the words 'Perfect' for each and the last two codes with the word 'Imperfect' for each.
Similarly, how would it be written so I could select a middle part of the code to use as the trigger to replace the code with something different, e.g. if I wanted to use the 'PART' from the first two codes?
I have discovered that the REPLACE and CASE functions don't work with % (so I am looking for any code that starts with what I stipulate but can end with anything (or using it on either side of the middle part of the code)).
Any help would really be appreciated please.
