select (sum(ColA) + sum(ColB) + sum(ColC)) / 3
from tableA
Where ....
I want to add the sum of the columns and then divide it by a constant. The problem I am having is there are a lot of nulls in the database that I am working on (i.e. one of the values in the ColB is Null, which makes the result of the entire expession null).
How do I get around this. I need to add the values of the columns?
I have a pivot transform that pivots a batch type. After the pivot, each batch type has its own row with null values for the other batch types that were pivoted. I want to group two fields and max() the remaining batch types so that the multiple rows are displayed on one row. I tried using the aggregate transform, but since the batch type field is a string, the max() function fails in the package. Is there another transform or can I use the aggragate transform another way so that the max() will work on a string?
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.
I have a DTSX package which reads values from a fixed-length text file using a data reader and writes some of the column values from the file to an Oracle table. We have used this DTSX several times without incident but recently the process started inserting NULL values for some of the columns when there was a valid value in the source file. If we extract some of the rows from the source file into a smaller file (i.e 10 rows which incorrectly returned NULLs) and run them through the same package they write the correct values to the table, but running the complete file again results in the NULL values error. As well, if we rerun the same file multiple times the incidence of NULL values varies slightly and does not always seem to impact the same rows. I tried outputting data to a log file to see if I can determine what happens and no error messages are returned but it seems to be the case that the NULL values occur after pulling in the data via a Data Reader. Has anyone seen anything like this before or does anyone have a suggestion on how to try and get some additional debugging information around this error?
If I have a Select statement like this in my C# code: Select * From foods Where foodgroup In (@foodgroup) And I want @foodgroup to have these values ... "meat", "dairy", fruit", what is the correct way to add the parameter? I tried meat, dairy, fruit 'meat', 'dairy', 'fruit' but neither worked. Is this possible?
I have SQL Server 2012 SSIS. I have Excel source and OLE DB Destination.I have problem with importing CustomerSales column.CustomerSales values like 1000.00,2000.10,3000.30,NotAvailable.So I have decimal values and nvarchar mixed in on Excel column. This is requirement for solution.However SSIS reads only numeric values correctly and nvarchar values are set as Null. Why?
CREATE TABLE [dbo].[Import_CustomerSales]( Â [CustomerId] [nvarchar](50) NULL, Â [CustomeName] [nvarchar](50) NULL, Â [CustomerSales] [nvarchar](50) NULL ) ON [PRIMARY]
can somebody explain me how I can assign a NULL value to a datetime type field in the script transformation editor in a data flow task. In the script hereunder, Row.Datum1_IsNull is true, but still Row.OutputDatum1 will be assigned a value '0001-01-01' which generates an error (not a valid datetime). All alternatives known to me (CDate("") or Convert.ToDateTime("") or Convert.ToDateTime(System.DBNull.Value)) were not successful. Leaving out the ELSE clause generates following error: Error: Year, Month, and Day parameters describe an un-representable DateTime.
My query "select blah, blah, rank from tablewithscores" will return results that can legitimately hold nulls in the rank column. I want to order on the rank column, but those nulls should appear at the bottom of the list
Hi All, I've one table named tableAB. in that i've added one new column with not null option in the enterprise manager. then i've generated the script, and run the script in client database. because already data is there, it is not accepting to put null value in the new column. so the is missing. anyway backup is there with me.
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'm merge replicating a SQL Server 2005 database (publisher) to SQL Compact databases (subscribers) on mobile devices. I understood that I could add a "not null" column to a replicated table on the server as long as I specified a default value, but it seems this is not possible. I ran the following script on the server database:
ALTER TABLE Activity ADD ActivityRequiresProject bit not null default(0)
which executed OK. When I went to synchronize the db on the mobile device I got the following error:
Alter table only allows columns to be added which can contain null values. The column cannot be added to the table because it does not allow null values. The SQL statement failed to execute. If this occurred while using merge replication, this is an internal error. If this occurred while using RDA, then the SQL statement is invalid either on the PULL statement or on the SubmitSQL statement. [ SQL statement = alter table "Activity" add "ActivityRequiresProject" bit not NULL constraint "DF__Activity__Activi__4A47DDAE" default ( ( 0 ) ) ]
Does anyone know if this is a valid error? Is is possible to add a not null column with default, and if not how do I update the schema on a replicated database?
I have an SSIS package that imports data from an Excel file, replaces any value in Excel that reads "NULL" to "", then writes the data to a couple of databases.
What I have discovered today, is I have two columns of dates, an admit date and discharge date column, and what I need to do is anywhere I have a null value in the discharge date column, I have to replace it with the value in the admit date column.Â
I have searched around online and tried a few things using the Replace funtion in Derived columns but no dice so far.Â
I am having problems adding a date field to a SQL Server Database from a form in ASP.Net. When I leave the date field blank, it automatically inserts Monday, January 01, 1900. I want it to be null when the expiration date is left blank. Can someone please help me with this?

I'm new to replication and am trying to determine the best approach to add a column (NOT NULL with no DEFAULT) to a replicated table. The only success I have had is if I do the following:
Delete entire Subscription Delete entire Publication Add column to table Create new Publication Create new Subscription Run SnapShot
The problem with this approach is that each step affects the entire database and not just the modified table. I think it is inefficient to redo replication for a simple object change. What am I missing? Is there a way to only replicate the changes made to the one table without having to run a SnapShot for the entire publication? Keep in mind the column must be defined as NOT NULL and cannot have a Default.
I have 21 Boolean fields that I would like to calculate a percentage from. If the boolean value is true I would like to be able to return a percentage of Outcomes available from a possible of 21. So If 7 of my boolean fileds are true then i would like to be able to calculate that 33% of Outcomes are present.
Does anyone have anything that will get me started?

I have a table with 6 columns. which we can call a, b, c, d, e, f. What I want to achieve is to put data in column d and e and then split this result in column f.
The data I want to put in column d and e is already exported and executed from a table called exp_data, which is from a period of november.
So this is what i have so far but is not working:
update split_table set d = select amount from exp_data where period = '1111' and exp_data.account = split_table.b and exp_data.company = split_table.a
The error I get is incorrect syntax near select. Fixed the issue by adding a parenthesis before the select until the end...
Hi! I have one table with thousands of records. Now, I have to add one more column to that table. And this new column will contain concatination of two columns in that same table. Is there any command to do this? My table has two columns as 'file', 'extn', now i want to add 'fullname' column to that table, and it will contain the concatinated value of 'file' and 'extn'. If the 'file' field has one record as "myfile", 'extn' has one record as ".doc", I want to insert "myfile.doc" in the new column 'fullname'. Like this my table has thousands of records. How can i do this? Please help me! Thanks in advance!

I am building a website in asp.net 1.1 with vb.net 2003 which will have the standings of the teams in our baseball league. Below is the database table I have created.
ID(int) home_team (nvarchar) away_team(nvarchar) win_teampf(nvarchar) lose_teampf(nvarchar) 1 Elmwood Murdock 7 22 Louisville Manley 4 33 Manley Elmwood 9 8 ID is the primary key. What I am attempting to do is add each instance of Elmwood from the win column to output the total number of wins from Elmwood and do the same for Elmwood in the losing team to output the total number of losses. The result will look something like this: Elmwood: 1 Win 1 Loss. .500 Thanks for your reply.
Whats the fastest easiest way to take a select that returns say 4 values for the expression into a single column on defined row
basically I mean i want to do an update to say a persons i dunno ummm places they have traveled and I want it listed like france;usa;germany etc etc and the data would always be in the tables i pull from so I can overwrite the data each time i run it but has to take 3 or more values from a query and put them in separated by say a ; into the same persons coloumn that stores the info.
I did this once before with a cursor and adding a variable to itself with colasce or whatever the command was, but was just wondering if there is a fast way to do this by chance that im not thinking about :P.
This is probably the wrong category to post my question in. Apologies if it is.
I have got a Data Flow Task that has an OLE DB Source and a Flat file destination.
Is there a way to do the following:
SELECT id,'31809','C:LCImportDataImages' & id & '.jpg', '1' FROM table1
This obviously doesn't work but I want to insert the id from the table, followed by the value '31809', followed by 'C:LCImportDataImagesid.jpg', followed by '1'
So, the id in 'C:LCImportDataImagesid.jpg' is the same as the id from the table.

HiI've got a quandry - I have a detailed database that handles advertorders between a design agency and printers / magazines etc.I want to add up the total spent by the client and put the results to afield.I've actually done that using a query table in access - it should bequite simple as i can bind the 'total amount' to my table - the onlything it does not currently do is filter the total based on the monthselected.For example if you look athttp://www.daneverton.com/dg2data/months/2006-12.aspThe data here is filtered by the issue equaling Dec-2006The actual order total is £13,622 but the column is showing the totalfor all entries to date (a years worth = £ 422,048)I'm sure that there is only a basic tweak required but i'm banging myhead over what to doThe sql is "SELECT * FROM monnodraught, q_monodraught_total WHERE[Issue / Edition] LIKE ? ORDER BY Publication ASC"Any help gladly received.
I'm trying to write a stored procedure that performs a select statement of the RequestID column and the total of the disk size for that row. ie the values on RequestAdditionalDisk1Size + RequestAdditionalDisk2Size + RequestAdditionalDisk3Size where the Requester equals a certain value. I can perform the select statement fine on the individual values, how to add the values of the Disk sizes together and present that back in the select statement.So far the code looks like but is giving me an error around the line performing a SUM.

I am mapping an entity from SQL 2005 to another entity in another system on SQL 2000. Since the destination system has its own ID generator, I want to keep the generated ID for each row of my table in a column of my table in SQL 2005. The new column is in the dataset now , but I don't know how to update my table to have that column values (The OleDbDestination just insert new items.)
Hi, I ve a table, I want to fetch certain rows based on the value of a Column. That column is nullable, and contains NULL values.I used the following query,SELECT Col_A FROM TABLE1 WHERE SOME_ID = 1317 AND Col_B NOT IN (8,9) Here, Col_B contains NULL values too. I need to fetch all rows where Col_B is not 8 or 9.Now, if I use "NOT IN", it does not work. I tried reading on it and got to know why it does not work. Even "NOT EXISTS" does not help. But still I've to fetch my values. How do I do that?Thanks & Regards,Jahanzeb
