Default To NULL Instead Of Blank/empty String During Flat File Import
Aug 15, 2006Hi,
In SSIS flat file import using fastload, I'm trying to import data into SQL 2005 previously created tables.
The table may contain column that are NULLable BUT there is NO DEFAULT for them.
If the incoming data from flat files contains nothing either between the delimeters, how can I have a NULL value inserted in the column instead of blank/empty string?
I didn't find an easy flag unless I'm doing something wrong. I know of at least two ways to do it the hard way:
1- set the DEFAULT(NULL) for EVERY column that needs this behaviour
2-set up some Derived Column option in the package to return NULL if the value is missing.
Both of the above are time consuming since I'm dealing with many tables. Is there a quick option to default the value to NULL WHEN there is NO data ELSE insert the data itself? So the same behavior that I have right now except that I want NULL in place of empty string/blank in the varchar(x) columns.
Thanks

Integration Services :: Empty String Is Showing As NULL Value In Database?
Oct 8, 2015In my source table, I have columns FirstName and LastName, both of datatype nvarchar. In my dataflow, I created two new derived columns mapped to these two columns. When pushing data to the source, I noticed that the FirstName column had a value of NULL while LastName was just an empty string (for rows that did not have any value).
My question is, why my source table column FirstName is showing a NULL value when the derived column datatype is string and the source is string? It should just be showing an empty string right?
Design Table Is Empty.
Mar 1, 2000I can use the Design Table option in every database and any user table on my server except for two databases which were transfered from a SQL 6.0 server.
I can't even use Design Table to create a new table in these databases. I get the Design form up and it allows me to add columns, but when I try to save the changes I get the following error message:
ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]Line 1: Incorrect syntax near 'full'.
[Microsoft][ODBC SQL Server Driver][SQL Server]Line 1: Incorrect syntax near 'full'.
One thing I have noticed is under Users for the database, all my users come up as 'via group membership' for the Database Access column for the database I am having problems with. All other databases the users come up as 'Permit' for the Database Access column. I assume this has to do with security. But I have tried everything to change this. I can not get a user to come up as 'Permit' under these two converted databases.
Does anyone have any ideas?

Bcp Out Empty String Into Csv Files

When I export this table into .csv file using bcp tool, empty string gets written as NUL character. Is there any way I can bcp out empty string as empty string itself instead of NUL to the file?

View 4 Replies View RelatedHow To Cast Empty String
Mar 22, 2006I want to replace a column value with a null if the string is empty. I would have thought this simple expression would do it:
RTRIM([FromContractSymbol]) == "" ? NULL(DT_STR, 0, 1252) : (DT_STR, 6, 1252)FromContractSymbol
Yet, I get the following error:
For operands of the conditional operator, the data type DT_STR is supported only for input columns and cast operators. The expression "...see above..." has a DT_STR operand that is not an input column or the result of a cast, and cannot be used with the conditional operation.
The expression works if I replace the NULL(DT_STR, 0, 1252) with say "A" and the expression works on other non-string columns. (As in "NULL(DT_I1) : (DT_I1)100")

Empty String Problem In Joined Data
Feb 13, 2008Hello,
I have a problem where I need to include data from a table where one of the joined columns can contain empty strings. The emptry string column and its related columns need to be included in the results of the query.
The Join looks like this:
SalesData.dbo.tbl_CYProcessedSales ps
INNER JOIN SalesData.dbo.vw_Product_CYProcessedSalesXref xr
ON ps.Prod = xr.Prod
AND ps.Acct = xr.AcctCode
INNER JOIN TxnRptg.dbo.vw_NetNewRevenueUnion nn
ON xr.BillingType = nn.BillingType
AND xr.ProdGroup = nn.Product
AND xr.AcctCode = nn.AcctCode
The problem occurs on the xr.BillingType = nn.BillingType portion of the join. the nn.BillingType can contain empty strings. I've tried a LEFT join to vw_NetNewRevenueUnion, but this has not worked.
In vw_NetNewRevenueUnion, BillingType becomes an empty string within a CASE statement if BillingType is NULL. I've thought about using something like 'All' in the ELSE condition, and doing the same in the vw_Product_CYProcessedSales view just so I don't have to deal with an empty string.
If I were not to do that, is there some way I can handle the empty string issue within the join so that empty string records will be included in the query results?
Thank you for your help!

Select Returning Nbsp Instead Of An Empty String
May 15, 2008
I am using a SQLDataSource with the following Select query. If the "spouse" values are not in the database, I get the HTML non-breaking-space character back, rather than an empty string.
SelectCommand="select applicant_id, (applicant_last_name + ', ' + applicant_first_name) as applicant_name, CONVERT(varchar(10), applicant_dob, 101) as applicant_dob, applicant_ssn, (spouse_last + ', ' + spouse_first) as spouse_name, CONVERT(varchar(10), spouse_dob, 101) as spouse_dob, spouse_ssn from applicant where applicant_last_name like '%'+@last_name+'%' order by applicant_last_name"
Here is the relevant code-behind:
TextBox tb = (TextBox)formView.FindControl("SpouseName");
tb.Text = e.Item.Cells[4].Text;
DatePicker dp = (DatePicker)formView.FindControl("SpouseDateOfBirth");
if (e.Item.Cells[5].Text.Length > 0)
{
try // this is a try/catch because nbsp is not parsed as a date
{
dp.DateValue = DateTime.Parse(e.Item.Cells[5].Text);
}
catch
{
dp.txtDate.Text = "";
}
}
tb = (TextBox)formView.FindControl("SpouseSocialSecurityNumber");
tb.Text = e.Item.Cells.Text;
Thoughts?

Detect And Convert An Empty String (from Textbox) To Null?
Jun 9, 2007Hi all,I have this code that I use for my Search function:SELECT DISTINCT [MUSIC_TITLE], [MUSIC_ORIGINAL_SINGER], [MUSIC_PERFORMER]FROM t_musicWHERE (@MUSIC_TITLE IS NULL OR [MUSIC_TITLE] LIKE '%' + @MUSIC_TITLE + '%') AND (@MUSIC_ARTIST IS NULL OR ([MUSIC_ORIGINAL_SINGER] LIKE '%' + @MUSIC_ARTIST + '%' OR [MUSIC_PERFORMER] LIKE '%' + @MUSIC_ARTIST + '%')) But right now if I don't enter anything in one of the textbox (2 have two, either of them can be left empty), the above Sql statement doesn't return anything since ADO.NET can't tell an empty textbox and treat it at null... So anyone please help me how to detect an empty textbox and set that to null for the above SQL statement to work. (It work in SQL Manager Studio, when I set one of the parameter = null.) I'm very new to ASP.NET stuffs, so if someone can help me to convert that function to code-behind and help me to call it from the .aspx, that would be even better as I don't want to put the code in my .aspx page... But I'm not quite there yet. Thank you all,Kenny.

Empty String Equals To Blank: How To Change This Behaviour?
Feb 11, 2008This seems to be a rather old problem (http://www.themssforum.com/SQLServer/Does-empty/) but I couldn't find an answer yet.
The problem is: I have two tables t1 and t2 where t1 is a staging area of t2.
t1: (id int not null, phone varchar(30))
t2: (id int not null, phone varchar(30))
Data in t1: (1, '') <- empty string
Data in t2: (1, ' ') <- a blank
Comparing t1.phone with t2.phone results in equality which in my opinion isn't correct.
The question ist: How can I change the behaviour of SQL-Server to result in inequality so that the change in my staging table is detected correctly?
Thanks in advance

Why Search On Empty String Returns Results With A Space?
Aug 1, 2007In sql server 2000 - our QA pointed out that his testing for empty strings returned 200 + rows but that when he clicked in the field there were obviously a space there. This issue came up because of the script I created to replace and earlier one that queried on empty strings instead of datalength and the earlier script always reported that it had updated x number of rows regardless of how many times it was run on the same database.
QA query based on the earlier script:
Select * from StringTable
WHERE (LongString = '' OR LongString IS NULL)
My script:
The fields are nvarchars in the newer database but older version of the database had varchars. I had created a script to replace empty strings as follows:
-- if LongString column is varchar - run varchar update else nvarchar update
If exists (Select * from sysobjects o
inner join syscolumns c on c.id = o.id
where c.name = 'LongString' and o.name = 'StringTable' and c.xtype = 167) begin
-- update varchar LongString
UPDATE StringTable
SET LongString = char(32)
-- Select * from StringTable
WHERE ((DATALENGTH(LongString ) < 1) OR LongString IS NULL)
END
Else Begin
-- update nvarchar LongString
UPDATE StringTable
SET LongString = char(32)
-- Select * from StringTable
WHERE ((DATALENGTH(LongString ) < 2) OR LongString IS NULL)
END
If exists (Select * from sysobjects o
inner join syscolumns c on c.id = o.id
where c.name = 'ShortString' and o.name = 'StringTable' and c.xtype = 167) begin
UPDATE StringTable
SET ShortString= char(32)
-- Select * from StringTable
WHERE ((DATALENGTH(ShortString) < 1) OR ShortString IS NULL)
END
Else Begin
-- update nvarchar ShortString
UPDATE StringTable
SET ShortString= char(32)
-- Select * from StringTable
WHERE ((DATALENGTH(ShortString) < 2) OR ShortString IS NULL)
END
My method for checking for datalength appears to work correctly why doesn't the QA script? I thought it might have to do with the nvarchar used in the table but I changed the column to a varchar and still has the same issue.
Thanks
