I have a problem that some of the data I reciave from the DB is null.
I would like to replace it with '0'.
I used the function IsNull on the SQL statment.
The problem is that I recaived a false/true values..
Is there an option to get the real data?
this is the SQL:
SELECT OrderDetails.itemID, OrderDetails.itemName, OrderDetails.quantityToPick, OrderDetails.quantityPicked, OrderDetails.colorDescription,
OrderDetails.colorDetails, OrderDetails.bases, OrderDetails.diameter, OrderDetails.axis, OrderDetails.referenceNum, OrderDetails.remarks,
Isnull(Stock.stockQuantity, 0) AS stockQuantity, OrderDetails.quantityOrdered, OrderDetails.status
FROM OrderDetails LEFT OUTER JOIN
Stock ON OrderDetails.itemID = Stock.itemID
WHERE (OrderDetails.storeID = @storeIDTemp)
Hey, I'm taking an intro SQL Server class, and I have a pretty simple homework assignment. We were provided with a DB and asked to write several SELECT statements. However, I'm stuck up one of the questions. Here is the question: 12.Create a SELECT statement that displays all employees and their Qualifications. Display that individuals with no Qualifications as having ‘NoQual’. Hint: Use a function to determine this ‘empty’ field using ISNULL.
Here is what I have:
SELECT FNAME + ' ' + LNAME AS 'Employee Name', ISNULL(QUALID, 'NoQual') AS 'Qualifications' FROM EMPLOYEE, QUALIFICATION WHERE EMPLOYEE.QUALID = QUALIFICATION.QUALID;
However, I do not get any results that have a NULL value in the QUALID column. Here is the code for the DB:
INSERT INTO position VALUES (1, 'President'); INSERT INTO position VALUES (2, 'Manager'); INSERT INTO position VALUES (3, 'Programmer'); INSERT INTO position VALUES (4, 'Accountant'); INSERT INTO position VALUES (5, 'Salesman');
INSERT INTO emplevel VALUES (1, 1, 25000); INSERT INTO emplevel VALUES (2, 25001, 50000); INSERT INTO emplevel VALUES (3, 50001, 100000); INSERT INTO emplevel VALUES (4, 100001, 500000);
INSERT INTO qualification VALUES (1, 'Doctorate'); INSERT INTO qualification VALUES (2, 'Masters'); INSERT INTO qualification VALUES (3, 'Bachelors'); INSERT INTO qualification VALUES (4, 'Associates'); INSERT INTO qualification VALUES (5, 'High School');
INSERT INTO dept VALUES (10, 'Finance', 'Charlotte', 123); INSERT INTO dept VALUES (20, 'InfoSys', 'New York', 543); INSERT INTO dept VALUES (30, 'Sales', 'Woodbridge', 135); INSERT INTO dept VALUES (40, 'Marketing', 'Los Angeles', 246);
okay, using isnull function we could replace null value.. but i want to do opposite, i want to replace if it's NOT null.. i tried notisnull also cannot..
Note : this is for select statement SELECT isnull(d.ClientID,'-') FROM blabla
How to replace something if it's not null SELECT isNOTnull(d.ClientID, '-')
SELECT JS_ID = ISNULL(ID.JS_ID,'-') FROM dbo.FM_INVOICE I, dbo.FM_INVOICE_DETAILS ID WHERE I.INVOICE_ID = ID.INVOICE_ID AND WO_ID = '-'--ISNULL(@GetLatest, '-')
is there any mistake i made? because it still return NULL when no data is found. how do i make it return '-' if a null is found
I'm constructing a single string of several counts with concatenated labels using SQL and want to not show zeros (or their labels). Is there a function within an SQL statement that will let me do this? ISNULL() sort of does this, but I really need to test for zero instead of NULL to eliminate noise data from the string.
The problem is that when a NULL data comes for COLUMN1, it doesn't insert the value of COLUMN2 as the formula estipulates. It looks like is not understanding de ISNULL function. Any suggestion? Thanks in advance.
i'm trying to run an append query using data from 2 tables. i want to replace nulls with blanks ('') bellow is my statment. when i run this statment with out the iif(isnull)) statmentes the query works fine. is there another way of replacing my nulls with blanks. Thank you, Thomas
insert into tblcustomers (cusName, cusNumber, Active, cusContact, cusCrLimit,cusTerms) SELECT dbo.tblCustomersIOA.CustomerName, dbo.tblCustomersIOA.Cust#, dbo.tblCustomersIOA.Active, iif(isnull(dbo.tblCustomersIOA.Contact),'',dbo.tbl CustomersIOA.Contact) , dbo.tblCustomersIOA.CreditLimit, FROM dbo.tblCustomerNotesIOA RIGHT OUTER JOIN dbo.tblCustomersIOA LEFT OUTER JOIN WHERE (dbo.tblCustomersIOA.CountryID = 1) AND (dbo.tblCustomersIOA.StateID = 2);
Dear GroupJust wondered how I can avoid the CHAR(32) to be inserted if @String1 is NULL?SET @String3 = ISNULL(@String1,'') + CHAR(32) + ISNULL(@String2,'')Thanks very much for your expertise and efforts!Best Regards,Martin
WITH MEMBER [Measures].[Parm1] AS [Member].[Member Deceased Year].currentmember.member_caption MEMBER [Measures].[ResultValue] AS ([Month].[Calendar].[Month].&[20150531], [Measures].[Member Count]) SELECT ({[Measures].[Parm1],[Measures].[ResultValue]}) ON COLUMNS, ORDER([Member].[Member Deceased Year].[Member Deceased Year], [Measures].[Parm1], DESC) ON ROWS FROM [TXERSDW]
Now from the Above query I am resulting with NULL as Parm1 values, I need to replace with a value of 12-31-9999 in the Parm1 if there are NULLS.
I'm attempting to use the isnull function to convert null values in a column to a blank. It works on the alpha field but not the numeric and I was wondering what can be done for numeric field conversion.
I am currently upgrading our ppc app (written in .net 2003) to .net 2005 and from sqlce 2.0 to 3.0. The new application runs out memory(storage) when handling lots of data transactions (both in case of using sqlcedatareader, and dataset ). There is no memory leak issue here, sqlce 3.0 simply uses a lot more (3 times more) memory than sqlce 2.0.
Our applicaton runs fine using sqlce 2.0 and .net 2003, but fail due to memory shortage
with the upgrades(which has the same code). Anyone can shed some lights on this issue?
Does anyone have any instructions on how to go about uprading a .sdf file from sqlce 2.0 to sqlce 3.0?
I found this on an msdn website (link: http://www.microsoft.com/sql/editions/sqlmobile/upgrading.mspx) but as you can see its very lacking on detail. (I included the link and content referring to upgrading the database files so you won't have to go to the link to see the part referring to upgrading the database.) I tried to run the upgrade.exe on my device but it doesn't explain how you're supposed to point it to the .sdf that you are trying to update. Here is the content on the above web page.
Upgrading Database Files You can upgrade a database created with an earlier version of SQL Server CE 2.0 to a database created with SQL Server Mobile by using the SQL Server Mobile Database Upgrade tool (upgrade.exe). The Database Upgrade tool runs on a smart device.
When you run the SQL Server Mobile Database Upgrade tool, the new SQL Server Mobile database is created on the smart device. The new database, with the file name extension .sdf, contains all the data that was in the source database. You need to reinitialize the upgraded database to continue using it for replication.
Note: If you are using replication or remote data access (RDA) as a connectivity solution before upgrading to SQL Server Mobile, you must synchronize the source SQL Server CE database (subscription database) with the SQL Server database (Publisher). The reason for synchronizing before upgrading to SQL Server Mobile is to ensure that any changes that exist in the tables on the SQL Server CE database are updated on the SQL Server database, because after the upgrade you must resubscribe or repull using the new database.
for the query i created i need zeros where ever the filed is blank. i have used count(acc) for selecting the count . can any one help me out with sample query. Thanks in advance
I have two tables, tblMTO and tblIMPORT_MTO. If I import an entire MTOinto the import table I want to create a delta from it (i.e. leave onlythe changed items). I have a view (simplified)SELECT dbo.tblIMPORT_MTO.ImportID, dbo.tblIMPORT_MTO.MTONo,dbo.tblIMPORT_MTO.Rev AS New_Rev, dbo.tblMTO.Rev AS Old_RevFROM dbo.tblIMPORT_MTO LEFT OUTER JOINdbo.tblMTO ON dbo.tblIMPORT_MTO.MTONo = dbo.tblMTO.MTONoNow to get all rows where old_rev = new_rev I also want all rows whereboth are null, is the best method to put ISNULL() in the view or toselect from the view using ISNULL in the criteria, e.g.select * from view1 where ISNULL(Old_Rev,0)=ISNULL(new_rev,0)or in the viewCREATE VIEW view1 asSELECT dbo.tblIMPORT_MTO.ImportID, dbo.tblIMPORT_MTO.MTONo,ISNULL(dbo.tblIMPORT_MTO.Rev,0) AS New_Rev, ISNULL(dbo.tblMTO.Rev ASOld_Rev,0)FROM dbo.tblIMPORT_MTO LEFT OUTER JOINdbo.tblMTO ON dbo.tblIMPORT_MTO.MTONo = dbo.tblMTO.MTONo;select * from view1 where Old_Rev=new_rev;
does sql server mobile 2005 support the isnull function? I'm getting an error when I try to use it and I don't know if it is becuase of using the isnull function or not, but when I run the same query on Sql Server 2005 it works fine.
I've seen lots of entries recommending the use of ISNULL in SQL WHERE clauses, e.g. in a search sproc where users can enter some or all parameters to search a table. Previously I would have used something like:SELECT * FROM MyTableWHERE (FName = @fname OR @fname IS NULL) AND(MName = @mname OR @mname IS NULL) AND(LName = @lname OR @lname IS NULL)So using the neat ISNULL syntax it could be updated to:SELECT * FROM MyTableWHERE (FName = ISNULL(@fname, FName)) AND(MName = ISNULL(@mname, MName)) AND(LName = ISNULL(@lname, LName))Having played around with this I stumbled upon a problem. If one of the fields, e.g. MName, is NULL then that clause will return false since MName = NULL isn't true and you have to use MName IS NULL. Did I miss all the caveats with using ISNULL in this way on fields that can contain NULL or have I missed something else?
I've got this query and it use to work or at least I thought it did. Could someone please help me with it. Thank you SELECT CID, CompletionDate, MarkedExport, CustomerName, EditUser, RouteID, WorkOrder FROM RouteCustomer WHERE (CompletionDate IS NOT NULL) AND (ExportDate IS NULL) AND (RouteID LIKE '%' + ISNULL(RouteID,@RouteID) + '%') AND (EditUser IS NULL OR EditUser = '' OR EditUser = @EmployeeID) AND (MONTH(CompletionDate) = ISNULL(MONTH(CompletionDate),@Month)) The problem comes with in the WHERE clause. What I wanted it to do is if the user did want to use a RouteID critera then the user would speified one else it wouldn't, and it was my belief that the ISNULL feature in SQL was the answer for that. same for the Month. I believe the EditUser is fine the way it is written. thanks to anyone that can help me with this. Rex
I have to display string "not assigined" when a datefield is null in a table. I am using like ISNULL(datefiled, "not assigned"), but I am getting following error Syntax error converting character string to smalldatetime data type. Is there any way, I can acheive desired result. Please help
To give you a little background, there is a CRM system with SQL server as its back-end. The CRM uses a view in SQL Server to list all the communications a user has had with his client over any given interval of time. Now there is a requirement to add a new column in the view that tells a user if the communication was filed in automatically or if it happened overnight via an automated archive manager process. I have achieved this using an expression field which is based on the comm_url field in the communications table in database.
example:
create view vCommunications as select col1, col2,...,case when comm_url is null then 'Manually filed' else 'Automatically Filed' as Filing from Communications
alternatively, this can also be achieved by the following:
create view vCommunications as select col1, col2,...,isnull(comm_url, 'Manually Filed') as Filing from Communications
Now my question is, given that there are many rows in the communications table, which of the above two expression fields will be more efficient in performance i.e. CASE versus ISNULL. I've checked a lot on google but I haven't been able to come up with a concrete answer.
I'm having a problem creating a isnull statement. I want to do two things I want to list all of the accounts that have a null value in a numeric field. And I want to update those accounts to 0.00. I tried: select Account_Num, isnull(TotalDDMFEE, 0) FROM Addr_20080402 But it returned all records
For the update I tried: update Addr_20080402 CASE when TotalDDMFEE = ' ' then TotalDDMFEE = 0.00 AND update Addr_20080402 CASE when TotalDDMFEE = isnull(TotalDDMFEE, 0) then TotalDDMFEE = 0.00
Any ideas how I should have written these two queries? Thanx, Trudye

Hi!I'm wondering whether it's possible to set up the MS SQL functionISNULL() as a default value to avoid NULL entries when importing datainto a table?!For example, I want the column1, to have a 0 (zero) as default value,when entering/importing data: isnull("column1",0)I remember that it is possible to set up with a date function likenow(), having for each record the current time as default value. Isthat also with isnull() somehow possible?Thx a lot!Peter
isnull(startweight) = case startWeight when NULL then 0 else startWeight end ?
I have read some where that using function on column while selecting a bunch of data makes the query slower because the function needs to work on each row of the table..
SO I was just thinking like
is the value of above 2 would be same perfrmance wise and value wise ?
I want to accomplish something like this , I want to sum two of my columns and pass them as input into a third column, looks pretty simple but I think the way ISNULL is handled in SSIS is different from the way it is handled in TSQL.
Basically I wanna write an expression for the following TSQL
(ISNULL(Column1 , 0) + ISNULL(Column2 ,0)) as Column3
I have a some currency fields that are sometimes null and I want to display them as '--' or something similar when they are such. I can do this with IIF statements, but I have a lot of them and would like a more manageable solution. I thought of the IsNull SQL Command, but the problem is that it won't let me insert char values into a currency field. Any other solutions? Thanks.
hello, I have a stored procedure that inserts or updates data depending of the value of one select that uses isnull finction. Here is the code:
