Convert Null To 0
Jan 8, 2004
Hi,
What would be the Syntax in a SELECT statement to convert a Null Value to 0,
ie,
SELECT RowID, Amount FROM TableA
and Amount is a smallmoney field. For example it is coming back with:
RowID Amount
1 2.3000
2 15.0300
3 NULL
4 7.8900
But I want it to return:
RowID Amount
1 2.3000
2 15.0300
3 0.0000
4 7.8900
Thanks

I am loading a flat file to a table but I also need to scrub the data a bit before the data hits the table. The main update required is converting a dot (.) character to a null value. The source file is using this character to indicate a blank. I know I can use the Dervived Column Transformation, but I have quite a few columns which will take a while to manually configure. Is there another transformation option that anyone can point me to?
Thanks

Hi
I've got a view which returns Null values due to an left outer join. The field which sometimes returns Nulls is called ClientCount. I want to create a new field which displays the value of ClientCount if ClientCount is not null and 0 if it is null.
In MS Access I use the following: IIF([ClientCount] Is Null,0,[ClientCount])
This does not seem to work in MS SQL. Is there some equivalent function I could use?
Thanks
David

i have a little confusion...
DECLARE @name varchar(30)
SET @name = NULL
SELECT ISNULL(CONVERT(DATE,@name),'')
Result: 1900-01-01
But..
DECLARE @name varchar(30)
SET @name = NULL
SELECT ISNULL(@name,'')
Does NULL inherit a datatype after convert?

Greetings -
I have a problem that I am unable to fix. I am migrating data from one ERP system to another ERP system.
I created a table in SQL via DTS by converting an excel file into an SQL Table.
The table has a column 'currentcost'. Most items in the table have a value in this column. However, some items have <null> in this column. I am updating another SQL table with currentcost that is in this column. However, my table being updated requires a value in its corresponding currentcost table. Therefore, my update statement terminates due to the source table having <null> values.
I tried an update statement to convert <null> into a '0'
It was 'update Source_New_ItemMaster set currentcost = '0' where currentcost = <null>
This obviously didn't work. How can a change a <null> value in an SQL table to '0' (zero)?

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.

Let me start by saying that I'm brand new to SQL Server 2005 and SSIS. I'm using the import wizard in SQL2005 to import from a flat file into a table and everything works fine except for dates. A typical date in my flat file is 01-JAN-06. 01 represents the day of the week, JAN represents the month and 06 represents the year. The flat file also contains date values of 00-XXX-00 which represent no date. For example a column containing last purchase date data would look like this:"DateOfLastOrder"
"01-JAN-06"
"02-JAN-06"
"00-XXX-00"
"03-DEC-05"The value of 00-XXX-00 means that there is no purchase date.I want to bring these columns into my table and replace the 00-XXX-00 values with a NULL.
The table Data Type is datetime.
If I use the import wizard using the example above I get this error message:
- Copying to [cpstest].[dbo].[date] (Error)
Messages
Error 0xc0202009: Data Flow Task: An OLE DB error has occurred. Error code: 0x80004005.

If I remove the 00-XXX-00 values and import something like this:
"DateOfLastOrder"
"01-JAN-06"
"02-JAN-06"
"03-DEC-05"
The import is successfull and the dates look correct in a querry.
SELECT *
FROM date
date
-----------------------
2006-01-01 00:00:00.000
2006-01-02 00:00:00.000
2005-12-03 00:00:00.000
(3 row(s) affected)
Does anyone know how I should go about getting these date columns into a datetime table and convert the 00-XXX-00 values into NULLs?
Thank you,
Ryan

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.

Using a reporting services model/report builder we have two related tables:
- Fundings, (parent)
- Draws, (child)
Report Builder reports that subtract "Total Fundings.Amount", (which is SUM(FundingAmount)) from "Total Draw Amount", (which is SUM(DrawAmount)) to get a balance work as expected except when there are no Draw rows, in which case a NULL is returned. Obviously we want to convert NULL values of "Total Draw Amount" to zero so that when subtracted from "Total Fundings.Amount" the correct value is displayed. I've searched for a function similar to COALESCE (Transact-SQL) in report builder but found nothing.
Can anybody help me with this?
Thanks

In the below scenario we are inserting some time related fields in Temp table.But its data type is varchar. Once data loading is finished in the temp table (Data is loading by source team SQOOP and they are unable to load if the source datatype is having Date or datetime) we have to alter the column datatypes. somehow, some character data in inserted in date columns (look at into 3rd insert statement). while altering the table it is failing. Can we do any alternative for this (Means if any varchar data that is non convertible to date can we make as null)
INSERT INTO ##TEMP_TEST
SELECT '2014-09-30','2017-10-06','Nov 6 2014 6:11AM','Nov 6 2014 6:11AM'
UNION SELECT '2014-09-29','2017-10-06','Nov 6 2014 6:11AM','Nov 6 2014 6:11AM'
UNION SELECT '2014-09-28','2017-10-06','Nov 6 2014 6:11AM','Nov 6 2014 6:11AM'
GO
INSERT INTO ##TEMP_TEST SELECT NULL,NULL,NULL,NULL

I need to pass in null/blank value in the date field or declare the field as string and convert date back to string.
I tried the 2nd option but I am having trouble converting the two digits of the recordset (rs_get_msp_info(2), 1, 2))) into a four digit yr. But it will only the yr in two digits.
The mfg_start_date is delcared as a string variable
mfg_start_date = CStr(CDate(Mid(rs_get_msp_info(2), 3, 2) & "/" & Mid(rs_get_msp_info(2), 5, 2) & "/" & Mid(rs_get_msp_info(2), 1, 2)))
option 1
I will have to declare the mfg_start_date as date but I need to send in a blank value for this variable in the stored procedure. It won't accept a null or blank value.
With refresh_shipping_sched
.ActiveConnection = CurrentProject.Connection
.CommandText = "spRefresh_shipping_sched"
.CommandType = adCmdStoredProc
.Parameters.Append .CreateParameter("ret_val", adInteger, adParamReturnValue)
.Parameters.Append .CreateParameter("@option", adInteger, adParamInput, 4, update_option)
.Parameters.Append .CreateParameter("@mfg_ord_num", adChar, adParamInput, mfg_ord_num_length, "")
.Parameters.Append .CreateParameter("@mfg_start_date", adChar, adParamInput, 10, "")
Set rs_refresh_shipping_sched = .Execute

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

Dear Experts,Ok, I hate to ask such a seemingly dumb question, but I'vealready spent far too much time on this. More that Iwould care to admit.In Sql server, how do I simply change a character into a number??????In Oracle, it is:select to_number(20.55)from dualTO_NUMBER(20.55)----------------20.55And we are on with our lives.In sql server, using the Northwinds database:SELECTr.regionid,STR(r.regionid,7,2) as a_string,CONVERT(numeric, STR(r.regionid,7,2)) as a_number,cast ( STR(r.regionid) as int ) as cast_to_numberFROM REGION R1 1.00112 2.00223 3.00334 4.0044SELECTr.regionid,STR(r.regionid,7,2) as a_string,CONVERT(numeric, STR(r.regionid,7,2) ) as a_number,cast (STR(r.regionid,7,2) as numeric ) as cast_to_numberFROM REGION R1 1.00112 2.00223 3.00334 4.0044Str converts from number to string in one motion.Isn't there a simple function in Sql Server to convertfrom string to number?What is the secret?Thanks

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

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!!

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"?
