hi,
my structure table in database:
Amount float(53) not null default 0
when i try to run his script:
alter table ABC alter column Amount float(53) null
it can only set the Amount to allow null, but can't set the default
value to empty.
anyone know how to set the field to allow null and default set to
empty, no value.
thanks
Hi,
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

I have a stored procedure with a SELECT statement, that retrieves 1 row.
SELECT name FROM tblNames WHERE nameID = "1"
I want all the NULL values in that row to be change in some default values.
How do I do this?
I have a report that is run on a monthly basis with a default date of null. The stored procedure determines the month-end date that it should use should it be sent a null date.
The report works fine when I tell it to create a history entry; however, when I try to add a subscription it doesn't appear to like the null parameter value. Since I have told the report to have a default value of null it doesn't allow me to enter a value on the subscription page.
Now, I suppose I could remove the parameter altogether from the stored proc, but then the users would never be able to run the report for a previous time period. Can someone explain to me why default values aren't allowed to be used on subscriptions when they seem to work fine for ad hoc and scheduled reports? This is really quite frustrating as most of my reports require a date value and default to null so that the user doesn't have to enter them for the latest data.
An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help

I have 595 default constraints in my database. I can return a list of them using the following:
select * from sys.default_constraints
Is there a way I can return a list of just the ones where NULL is still allowed? I want to update all of the columns with a default value to not allow NULLs.
Hi all,
One of my columns is the table has some Null values, and I Would like to stop having NULL values into that column any more.
I know, If I alter the column to NOT NULL will throw me an error, since it does a batch update.
Is there any way to achieve this...
Thanks...
Hey. I need to substitute a value from a table if the input var is null. This is fine if the value coming from table is not null. But, it the table value is also null, it doesn't work. The problem I'm getting is in the isnull line which is in Dark green color because @inFileVersion is set to null explicitly and when the isnull function evaluates, value returned from DR.FileVersion is also null which is correct. I want the null=null to return true which is why i set ansi_nulls off. But it doesn't return anything. And the select statement should return something but in my case it returns null. If I comment the isnull statements in the where clause, everything works fine. Please tell me what am I doing wrong. Is it possible to do this without setting the ansi_nulls to off??? Thank you
set ansi_nulls off
go
declare
@inFileName VARCHAR (100),
@inFileSize INT,
@Id int,
@inlanguageid INT,
@inFileVersion VARCHAR (100),
@ExeState int
set @inFileName = 'A0006337.EXE'
set @inFileSize = 28796
set @Id= 1
set @inlanguageid =null
set @inFileVersion =NULL
set @ExeState =0
select Dr.StateID from table1 dR
where
DR.[FileName] = @inFileName
AND DR.FileSize =@inFileSize
AND DR.FileVersion = isnull(@inFileVersion,DR.FileVersion)
AND DR.languageid = isnull(@inlanguageid,null)
AND DR.[ID]= @ID
)
go
set ansi_nulls on
Hello,
I have a query that returns the appropriate values I need, however there is one field I'd like to add and utilize but my problem is I only want to use it if it contains data.
If I filter it with IS NOT NULL it returns all the records, including the empty records. The field is simply empty, and doesn't come back as NULL. If I filter it with =' ' , it shows all the records with the empty records only.
I need to do the opposite, be able to filter it only if it's not empty.
Any help would be appreciated.
Is there any way in SQL Server 6.5 to change a column that was originally set up as nullable to not accept nulls? None of the values in this column contain null values. I need to add a primary key constraint on the column for replication purposes and SQL won't let me because the column is nullable.
Thanks!

Hi,
In my SQL Server database one of the tables column has to be changed from NOT NULL to NULL. The table has got records.
Thanks in advance,
Srini
example
create view v_GuestOrder
as
Select T1.id_Guest,T2.OrderName
from Guest T1
left join Order T2 T2.id_order = T1.Id_order
select * from v_GuestOrder
--
Id_Guest OrderName
-------- -----
1 spoon
2 phone
3
4 tv
I need something similar to
Select
id_Guest,
case orderName
when '' then Null -- Sql server gives error in thsi case
end as orderName
from v_GuestOrder
So I need to assign NULL to OrderName is query return empty string,
it will be treated by Crystal reports as Null
Please help , thanks
How can I make empty cells show NULL on my table? Some cells show NULL others won't. Does this mean that they have contents?
The reason being is that, when I use the code
Select *
From Employees
Where JobDescription1 Like '%montly%'
Those with empty jobdescription1 show with the legitimate results.
Any help please?
Thanks!
I've inherited a terribly designed database. When cells in the tables have nothing in them, rather than being NULL, they're just empty. So now I can't use COALESCE...
Is there a way for COALESCE to check if a cell is empty instead of NULL? And if not, is there a way to get around this?
I need to check in my Stored procedure if the information passed is null or empty so I can decided to insert the new value or keep the old. How do I accomplish this please in T-SQL. Thanks in advance.

Trying to insert null value into sql table, but not working, if I use:
if (strMyText.Length == 0) command.Parameters.Add("@Text", DBNull.Value); // or using:("@Text", null), or using:("@Text", DBNull) else command.Parameters.AddWithValue("@Text", strMyText);
When I go back to table, I see the value is: 'NULL', has single quotation mark, suppose to be: NULL
Where is the problem?
Thanks a lot.

Well met,
Let's say I have a web form that allows users to insert and update records in a SQL database. Is it better to set empty web controls (textbox, etc.) to DBNull or let it go as an empty string into the database?
Example code:
if (tboxNAME.Text == "")
{
sqlCommand1.Parameters["@NAME"].Value = DBNull.Value;
}
else
{
sqlCommand1.Parameters["@NAME"].Value = tboxNAME.Text;
}
Is the above overkill? It seems like it would be a good idea to set fields which the user empties back to Null rather than an empty string.
Thanks,

Hi all, I have some columns in my database which allows null. I want to know if leaving the field to be NULL or storing an empty string into the field, which will take up more space?? if the field type is varchar(100)
View 5 Replies View RelatedHi folks,
I've have about 100 tables, for some reasons, column values that are originally NULL was inserted as emtpy string. So, I am wondering if I can write JUST ONE SQL (hopefully don't have to specify the field names in the SQL as well) for each table so that all the empty strings will be converted back to NULL.
THANKS JOHN
I added a new field to an existing ETL process which uses SSIS to ingest a CSV file. The new field in the file, Call_Transaction_ID, will not always be populated for every record and so can be NULL or empty for certain records.
Here's the problem:After the file is extracted into a staging table, the Call_Transaction_ID field is showing blank or empty when it has no ID for that particular record. The problem is when I try to then ETL this data into a fact table - I'm trying to set the Call_Transaction_ID field to -1 if it is NULL or empty, however SQL Server doesn't see the field as empty even though there is no value in the field so -1 will NEVER return.
Using a WHERE DATALENGTH(Call_Transaction_ID) = 0 returns 0 records, again because SQL Server doesn't see the field as empty or NULL.
What do I do now to get around this? How do I fix it?
I am working on a cube and I want to hide the results of a calculation if it is zero.
It is an inventory problem based on a transaction pattern. (add plus one to the inventory, add minus one to the inventory).
The sum of those two is zero, but the cube get messed but by thousands of zero.
I found some solutions of displaying 0 for NULL but I want to dispaly NULL (or empty) for 0.
How do I define a field to have the default value = ''. Not NULL but not a space either in SQL Server 2005?

The output should be 'i am empty' but when i execute this i am getting ' i am not empty'. even i did browse through but i don't find the difference in my logic.
I have always (or at least intended to) treat NULL and empty strings separately in my SQL querying history. Now I have run across something that mystifies me (but probably shouldn't) that I would like an explanation for.
Consider this bit o' code:
DECLARE @ORDER CHAR(10)
SET @ORDER=
(
SELECT NULL
)
IF @ORDER <> ''
PRINT 'Not an empty string'
IF @ORDER IS NULL
PRINT 'It is NULL'
Run this and you will get:
It is NULL
I was expecting:
Not an empty string
It is NULL
Why is NULL not passing the 'not an empty string' test? In other words, how does NULL = '' ? Is NULL cast to an empty string for this comparison?
I am using the below query to calculate column values. But I need to return zero when a column values is empty or null.
select [Funding] [Fundings],
[Original] AS [Originals],
[Variance] = SUM([Previous_Year]-[Current_Year]),
[SumValue] = SUM([CurrentYear]/4),
[ActualValue] = SUM([Variance] * 0.75),
[FinanceYear],
[New Value] = SUM([Previous_Year]+[Current_Year])
from Finance
GROUP BY [Original], [FinanceYear]

HI,
I am using XmlDataDocuments returned by webservices and query in the reports to populate the reports.
The issue I have is if the dataset used to populate the XML document has any nulls or empty spaces in any field the whole column or row is missing in the data generated by my query in the Reports. Sometimes the whole data is not being returned to the reports.
Sample query I use
<Query>
<SoapAction>http://xxxx.webservices.org/SelectReportRegisters</SoapAction>
<Method Namespace="http://xxxx.webservices.org/" Name="SelectReportRegisters">
<Parameters>
<Parameter Name="p_registerType">
<DefaultValue>All</DefaultValue>
</Parameter>
<Parameter Name="p_registerName">
<DefaultValue>All</DefaultValue>
</Parameter>
<Parameter Name="p_asOfDate">
<DefaultValue>7-1-2009</DefaultValue>
</Parameter>
</Parameters>
</Method>
</Query>
I have tested the webservice with sample data and it works well, returns data.
I use the ISNULL() in my stored procedures to avoid nulls but with empty strings, replacing them with a default value in the managed code is expensive and slows down the reports.
Is there some feature I am missing because of which nulls and empty strings are causing this problem.
I am using Reporting services 2005.
Any pointers will be truly appreciated.
Hi 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.

Can this be done? I couldn't find a setting for it.
