Is there a way to ignore a column/variable when the whole result set for the applied filter (where) is null?
Not all clients have data for every variable, i.e. some variables are client specific. There are too many variables and clients to amend the select query every time so I just want to ignore a col if its null.
I hope that makes sense (my inability to describe it might explain my inability to find anything related to it!)
The next step would be to run all clients' data in one go using, I believe, a cursor, but one step at a time!
I have a query where one or more of the columns returned is a resultfrom a subquery. These columns get their own alias. I want to filterout the rows containing NULL from the subqueries but it just won'twork. When running columnAlias IS NOT NULL i just get the error"Invalid column name 'columnAlias'.This is the query:SELECT k.UserId, k.Lastname, k.Firstname,(SELECT kscr.answer FROM Results kscr WHERE kscr.UserID =k.UserID) AS myColumnAliasFROM Users kWHERE myColumnAlias IS NOT NULL)When running without the WHERE clause, I get the following results:UserId Lastname Firstname myColumnAlias113 Norman Ola jepps820 Karlsen Kjell830 Pens Jens juubidooWhat I want is to get rid of UserId=820. What am I doing wrong?
SELECT expense_id, CAST(expense_id AS char(10)) + ' - ' + CAST(trip_km AS char(5))+ ' - ' + CAST(expense_amount AS char(5)) + ' - ' + charge_centre AS ExpenseDesc
If charge center is null, I need to ignore this field. How can I achieve this? The reason is that if any of the field is null, it will return ExpenseDesc as null.
Using SQL2000. According to Books Online, the avg aggregrate functionignores null values. ((3+3+3+3+Null)/5) predictably returns Null. Isthere a function to ignore the Null entry, adjust the divisor, andreturn a value of 3? For example:((3+3+3+3)/4) after ignoring Nullentry.If there's more than one null value, then adjust divisor accordingly.For example: ((5+5+5+4+Null+5+5+Null)/8) would be ((5+5+5+4+5+5)/6)after nulls ignored.Thanks for any help or advice.

Hi, I do have a stored procedure with parameters inside. I just want to ignore those parameters that are NULL so that my WHERE clause will not execute them anymore. Here's my code:
CREATE PROCEDURE SEARCHPATIENT @patnCode varchar(10) = NULL, @patnSurname varchar(20) = NULL, @patnGivenName1 varchar(20) = NULL AS SELECT.... FROM ... WHERE patnCode=@patncode AND patnSurname =@patnSurname AND patnGivenName1 =@patnGivenName1
BUT... If the user passes @patnSurname as NULL, I got an SQL error message: "There was an error executing the query.. Timeout expired... ". I was hoping I could write an WHERE clause where IT WILL ONLY EXECUTE those parameters WITH VALUE and IGNORE those NULLs.
Can someone help me on this? Can I use IF THEN ELSE statement inside the WHERE clause? Can I use CASE STATEMENT inside the WHERE clause?
I have a stored procedure which accepts 3 arguments that are used in the WHERE clause of a SELECT Statement
CREATE PROCEDURE [dbo].[MyProcedure] @argYear INT, @argMonth INT, @argDay INT
AS
SELECT *
FROM MyData
WHERE MyData.Year = @argYear AND MyData.Month = @argMonth AND MyData.Day = @argDay
The problem that I am having is @argDay is an "optional" argument. If @argDay is NULL then I want to basically ignore the "AND MyData.Day = @argDay" condition.
Is there an easier way to do this than:
IF @argDay is NULL
SELECT *
FROM MyData
WHERE
MyData.Year = @argYear AND MyData.Month = @argMonthELSE
SELECT *
FROM MyData
WHERE
MyData.Year = @argYear AND MyData.Month = @argMonth AND MyData.Day = @argDay
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?

Does not reproduce this problem (and so is a probable fix) but the questions remains, what causes this?
When configuring error output, I want everything that is good in the row to make it to the destination, and then the offending column that is causing an error to be set to NULL, and then sent to the destination as well. In addition, I want to take the offending column's data, and route it over to an error holding table. I know about the ability to redirect the whole row, but I just sort of want to redirect just that column. For example....
Have a table with 5 columns
col1 int null,
col2 int null,
col3 char(3) null,
col4 bit null,
col5 int null
My data flow loads data from a flat file and has a record that looks like this
1 5 ABC R 3
I want the row to make it to the destination as follows....
1 5 ABC NULL 3
Then the offending data needs to go over to my error table
I have a table with an Identity Column set up. I also have an index on the table that is set to Ignore Duplicate. Identity starts at 1 and is incremented by 1.
So first 5 rows inserted get identity
1
2
3
4
5
If I insert rows that get ignored because of the index with Ignore Duplicate, it is ignored correctly. But, the next row to get inserted will have an identity value of 7.
So, even though the insert was ignored because of the index with Ignore Duplicate, the Identity column was incremented behind the scenes.
Hello guys I have a very simple query that is to be used to verify what users have access to what servers. Here it is:
/* SQL Server & Windows NT login name, security access */ USE master go SELECT name, loginname, sysadmin, securityadmin, serveradmin, setupadmin, @@SERVERNAME FROM syslogins WHERE status != 0 AND ((sysadmin = 1) OR (securityadmin =1) OR (serveradmin =1) OR (setupadmin = 1))
I would like to know how to stop the columns that have a null or 0 value from being returned to me. I don't want to see a bunch of 0s since almost no users do have these privaleges, I'd rather have that be hidden. Do I need to create a view for this? Thank You!
In a query in SQL server 2005 I have a column LastName + ', ' + FirstName.All works fine except when a LastName or FirstName = NULL then the result is NULL.How do I get around this?ThanksA Newbie to SQL.
I want to remove the nulls from the result set so the result is 1 line. Code and results are below:
SELECT CustomerNumber, (case when yearseq = 2012 then isnull(sum(mainPower),0)+isnull(sum(sidePower),0)+isnull(Sum(leftPower),0) +isnull(Sum(netappPower),0)+isnull(Sum(rightPower),0)+isnull(Sum(lowerPower),0) end) as '2012', (case when yearseq = 2013 then
[Code] ....
What can I do to my code to remove the Nulls to the entire result is just 1 line?
I am getting this error: "Cannot insert the value NULL into column 'OrderID', table 'outman.outman.Contact'; column does not allow nulls. INSERT fails." -- But my value is not null. I did a response.write on it and it show the value. Of course, it would be nice if I could do a breakpoint but that doesn't seem to be working. I'll attach a couple of images below of my code, the error, and the breakpoint error.

We have a database where many tables have a field that has to be lengthened. In some cases this is a primary key or part of a primary key. The table in question is:-
/****** Object: Table [dbo].[DTb_HWSQueueMonthEnd] Script Date: 09/25/2014 14:05:09 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[DTb_HWSQueueMonthEnd](
[Code] ....
The script I am using is
DECLARE@Column varchar(100)--The name of the column to change DECLARE@size varchar(5)--The new size of the column DECLARE @TSQL varchar(255)--Contains the code to be executed DECLARE @Object varchar(50)--Holds the name of the table DECLARE @dropc varchar(255)-- Drop constraint script
[Code] ....
When I the the script I get the error message Could not create constraint. See previous errors.
Looking at the strings I build
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] DROP CONSTRAINT PK_DTb_HWSQueueMonthEnd ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] Alter Column [Patient System Number] varchar(10) ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] ADD CONSTRAINT PK_DTb_HWSQueueMonthEnd PRIMARY KEY NONCLUSTERED ([Patient System Number] ASC,[Episode Number] ASC,[CensusDate] ASC) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
They all seem fine except the last one which returns the error
Msg 8111, Level 16, State 1, Line 1 Cannot define PRIMARY KEY constraint on nullable column in table 'DTb_HWSQueueMonthEnd'. Msg 1750, Level 16, State 0, Line 1 Could not create constraint. See previous errors.
None of the fields I try to create the key on are nullable.
I receive this message when I try to run any report. The reportserver and reportservertempdb databases were upgraded using backup/restore from SQL2000 to SQL2005 on a separate server which is running RS2005 . Please help. Thanks
The end result: I need one of the columns in my result set (col2) to have a preceeding apostrophe (i.e., '001234 ).
The problem: I am building my query as a string and then using the EXEC() function to execute it. For example: SET @strSQL = 'SELECT col1, col2 FROM mytable' EXEC(@strSQL)
Just to tame any answers that might not be directed to the specific question, the query Must be built as a string and then executed.
I have been unable to obtain the solution and I am wondering if it is even possible?
I am importing some data from Excel. I have to SUM one of the columns, and then use the result of the sum to calculate the percentages of each row. How can I use the Aggregate to give me a total of a column, so that i can use the total in another task and use formulas to calculate the percentages? i have tried to use multicast and join, but I get an extra row with the sum, which is not what I want; I want to use the sum for all the data.
I am trying to display component usage in January for the past year, if I want to display the year in different column, what should I do? eg. component_id component_description qty_used_on_2005_Jan qty_used_on_2006_Jan C58B0BDD tape drive 2 3 Currently I am using this sql: select cast(year(date_complete) as varchar(10)) + ' Jan' as Year, component_id, component_description,sum(component_qty) as total_qty_used from view_jobComponent where month(date_complete) = 1group by component_id, component_description, cast(year(date_complete) as varchar(10)) + ' Jan'order by component_id, component_description which I will get something like this: Year component_id component_description total_qty_used 2005 Jan C58B0BDD tape drive 22006 Jan C58B0BDD tape drive 3
How can I make this stored procedure concept work:
----------------------------------------------- Create Procedure MyProc @MyValue varchar(5) As Declare @ColumnName as varchar(11) Set @ColumnName = 'Price_' + @MyValue Select Sum(Price) As @ColumnName --???? From MyTable where Item = @MyValue Return -----------------------------------------------
Using @MyValue = 23 should make the Sum(Price) column name 'Price_23'. It's not working. What am I doing wrong?
