how can I insert a constant value such as the word "NoPhone" when a field value from a select statement is null?
Here is my code:
select AgencyName
,AgencyLoc,
,ISNULL(AgencyPhone.Agency,) as phone
How can we put in the words "nophone" when phone is null?
Hi all smart people,
Can someone please help me with how to replace null values with spaces in select statement.
I have to have a select statement which will select all the data but the field contain null value it has to replace with spaces. How can I do that ?
Thanks,
I need to separate the data from one column in to two columns based on the transaction type TRAN_TYPE (C is credit, D is Debit)
TRAN-TYPE| AMOUNT
C 20.00
D 30.00
C 50.00
To do that I have this code:
select
CASE WHEN TRAN_TYPE = 'D'THEN CAST (ISNULL(amount, 0) as varchar (30)) end as DEBIT,
CASE WHEN TRAN_TYPE = 'c'THEN CAST (ISNULL(amount, 0) as varchar (30)) end as CREDIT
FROM HISTORY
And my output is:
DEBIT | CREDIT
----------------
NULL | 20.00
------|-------
30.00 | NULL
------|-------
NULL | 50.00
------|-------

Can a Trigger be created to automatically replace NULL values with "-"? Suppose I have an Entry Form with 20 Text Boxes. I don't want to code in my application. I want that when an Insert Query is executed, a BEFORE/AFTER TRIGGER should be executed to replace the NULL values coming from Insert QUery to "-".
I also want to know whether to use a Trigger or a Function/Stored Procedure.

Hello,I'm a beginner in SQL and I have been searching through the SQL Cookbook and Google but I can't seem to find an example of what I want to do. I want to create a report that will return names and emails using two of my tables. I want to use the email in my primary table in the select but if it is null or empty I want to replace it with an email from my secondary table. Below is what I would like to do but I got a syntax error with it in SQL Server 2000. SELECT MemberID As ID, MemberFirstName As FirstName, MemberLastName As LastName, (IF MemberEmail = '' THEN SELECT TOP 1 OtherEmail FROM OtherTable WHERE OtherID = MemberID) As EmailFROM PrimaryTableThanks for your time.Jason

How to replace DateTime field with null value in SQL 2005 server
I create a stored procedure aa, It works well, but sometimes I hope to replace CreateDate field with null value,I don't know how to doIt seems that datetime type is not null value

Dear Community,We have a problem with null-Bytes in varchar-Columns, which are nothandled correctly in our application. Therefor we try to filter themout using the Transact-SQL REPLACE function.The Problem was, that the REPLACE-function didn't behave the way weexpected.Following Example demonstrates the behavior:declare @txt varchar(512)declare @i intset @txt = 'hello ' + char(0) + 'world'print @txtset @i = 1while @i <= len(@txt)beginprint str(@i) + substring(@txt, @i, 1)set @i = @i + 1endprint 'Length: ' + str(len(@txt))print 'trying to replace null-byte:'print replace(@txt, char(0), '*')print 'replace Letter h'print replace(@txt, 'h', char(39))-- end exampleOutput:hello1h2e3l4l5o678w9o10r11l12dLength: 12trying to replace null-byte:*replace Letter h'elloThe Null-Byte replace destroys the whole string. This behavior occursonly on some of ourdatabases. The others work correctly.Is it possible that it depends on some server setting?ThanksEnno

1.
Have a query that fetches a real value (e.g. 4.3345643)
Let say the field is called TheReal.
How can I format the value in the select statement so I get a thousand separator(s) and two decimals in the resultset.
2. In the same query I have a left join as well.
Table 2 retur (sometimes) <NULL>.
Is it possible to force this <NULL> value to be a fixed string value instead in the select statement.
Ok.. so I have a fixed position data feed. I read the file in as just whole rows initially, process a specific position and evaluate a conditional split to determine direction of the file for proper processing (file contains multiple recors with different layouts). This all works fine. I then use the derived column feature to process all the columns.
Most of the columns are as simple as SUBSTRING(RecordData,1,10) for example to get the first column. This all works for string data. I then have a column that is a date field. The problem occurs that the code SUBSTRING(RecordData,20,10) returns either a date or empty set of data if no date was in the original file. When this gets sent to the OLEDB connection (SQL Server 2005) into the date field it fails. If the record has a date it works, but if it is empty it fails the insert.
I tried to replace empty strings with NULLs with this code. REPLACE(TRIM(SUBSTRING(RecordData,20,10)),"",NULL(DT_WSTR,10)). This does not work. So my question is how do I bring a date field from a fixed flat file into a SQL datetime field using a derived column? More specifically is how do I set it to NULL if its empty data? When I use the above code it inserts all the rows from the file, but it sets all rows to NULL not just the empty ones.
Thanks.
I need to convert a a string column to integer. Before converting, I need to check if it has blank values then convert it to NULL. Someone told me that its easier to convert it to NULL before converting to integer.
View 5 Replies View RelatedHey. 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
In my report i have CNAME parameter , which allows null value. I checked Allow null value check box in report parameter properties.
when i preview the report , it displays checked NULL check box beside CNAME parameter . I want to give some meaningful name(i.e.ALLCustomers) to this checkbox instead of NULL.
Is it possible through SSRS designer?
I have a flat file with the following columns
SampleID Rep_Number Product Protein Fat Solids
In the flat file SampleID and Product are populated in the first row only, rest of the rows only have values for Rep_Number, Protein, Fat, Solids.
SampleID and Product are blank for the rest of the rows. So my task is to fill those blank rows with the first row that has the sampleID and Product and load into the table.
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
Key cannot be null. Parameter name: key
I run a stored procedure for which I have a return variable. The stored procedure returns the ID of a row in a table if it exists:
m_sqlCmd.ExecuteScalar();
The m_sqlCmd has been fed an SQLParameter with direction set to output.
When the stored proc returns, I want to test it. Now when there IS a row it returns the ID ok.
When the row doesn't exist, in my watch I have:
m_sqlParam.SqlValue with value {Null}
I can't seem to work out how to test this value out.
I've tried several things but none seem to work.
This line compiles ok, but the following runs into the IF statement as if the SqlValue is null??
if (m_sqlParam.SqlValue != null)....
{
// I'm here!! I thought the watch says this is null???
}
Sorry if this is obvious, but I can't work this one out!!
Looks like there was a fix and then I read this fix is not a fix. Does anyone know how this can be rectified? Does it mean that only Windows authentiation is the only way it works. The Software is over 2 years old, there are no excuses.

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?
We have a case where in we should show date based on conditions for e.g if we had a column defined as
col varchar(10) then we would show col as 'NULL' for some condition and actual value when no condition
Normaly date values are stored here e.g under col 20150901 .
Case
when col>'20150901' then 'NULL'
else col
end as Derivedcol
Note this is an extract process and we are presenting data by pumping the data in a table .
Now there is another similar column -colz varchar(10) which stores date but doesnt have case condition so whenever date has no value its shows null which is database null.
So whats the difference between database null and string null ?
How can we show database null for the case condition instead of string "null"?
I have two columns A (which allows nulls) and B( which does not allow nulls).
How can I add the contents of columns A and B SO THAT I DO NOT GET A NULL RESULT WHEN A IS NULL.
The result of A+B concatanation will be stored in a column, C.
Appreciate your help

Hi guys,
I've got a query on a particular table returning an odd result:
SELECT DISTINCT WorkStation
FROM Invoice
WHERE WorkStation Is Not Null
ORDER BY WorkStation
This query returns the rows I'd expect plus a null row. This doesn't happen in databases at other sites, or in other tables at this site. The following query behaves as I'd expect returning only non-null AccountNumbers.
SELECT DISTINCT AccountNumber
FROM Suppliers
WHERE AccountNumber Is Not Null
ORDER BY AccountNumber
I can't reproduce these results on another site on a table of the same structure, or on another table at this site.
Any suggestions as to what might be going on?

I have 595 default constraints in my database. I can return a list of them using the following:

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...
ok here is a WIERD issue.
I've NEVER EVER had this issue, I have always done this and it works great both locally and remotely.
I have a table, which is a "customers" table.
I have a stored procedure which takes in parameters (name, address, password etc...) and returns me back, via a parameter declared as output - the customer ID.
I've always done this, and works great.
Now, this works fine locally.
IF I try to run this/do the exact same execution of commands (create a customer) remotely (where the database is stored, so copying everything from local to "over there") it does not work.
I get a DBNULL value back from the parameter, declared as an int output.
IF I copy and paste this Stored procedure Query/command into Query Analyzer and execute it (on the remote connection) and run it, giving it the exact same values as I do, it works perfect and returns me the correct value.
I've even dropped and recreated the stored procedure but makes no difference.
Any ideas why?
here is the proc....
CREATE PROCEDURE [dbo].[DoCreateNewCustomer] (
@theFirstName nvarchar(25),
@theLastName nvarchar(25),
@theAddress nvarchar(50),
@theCity nvarchar(15),
@thePostCode nvarchar(9),
@thePhoneNumber nvarchar(21),
@theMobilePhoneNumber nvarchar(21),
@theIPAddress nvarchar(25),
@thePassword nvarchar(50),
@theEmailAddress nvarchar(30),
@result int output
)
AS
SET @result = (SELECT [ID] FROM Customers WHERE emailAddress = @theEmailAddress)
IF @result IS NOT NULL
SET @result = -1
ELSE
BEGIN
SET @result = @@IDENTITY
INSERT INTO Customers (
Firstname,
Lastname,
Address,
City,
Postcode,
PhoneNumber,
MobileNumber,
IPAddress,
[Password],
EmailAddress
)
VALUES (
@theFirstName,
@theLastName,
@theAddress,
@theCity,
@thePostCode,
@thePhoneNumber,
@theMobilePhoneNumber,
@theIPAddress,
@thePassword,
@theEmailAddress
)
END
GO
Any ideas why it does not work when calling the stored proc from either a web app, or through QA remotely but works fine when I run that command in QA or locally?
Again, if I do:
EXEC DoCreateNewCustomer { params } - the output result it gives me is DBNULL (if on remote connection)
If I do this locally, perfect
If I copy and paste pretty much the SP into QA and execute it on the remote connection, works great, and also locally.
