IsNull() Works In Query But Not In Stored Procedur

May 29, 2007

Hi,

I'm using IsNULL(<insert something SQL witty here>) to zero out a derived column if there's no return result. When I submit my query in Management Console the results come back perfectly, when I send it over as a stored procedure (as an alter or create) then execute, my last few columns come back 0 not populated as in the query run. Anyone know why this happens?

SELECT Query - Different Columns/Number Of Columns In Condition

Sep 10, 2007

I am working on a Statistical Reporting system where:


Data Repository: SQL Server 2005
Business Logic Tier: Views, User Defined Functions, Stored Procedures
Data Access Tier: Stored Procedures
Presentation Tier: Reporting ServicesThe end user will be able to slice & dice the data for the report by


different organizational hierarchies
different number of layers within a hierarchy
select a organization or select All of the organizations with the organizational hierarchy
combinations of selection criteria, where this selection criteria is independent of each other, and also differeBelow is an example of 2 Organizational Hierarchies:
Hierarchy 1


Country -> Work Group -> Project Team (Project Team within Work Group within Country)
Hierarchy 2


Client -> Contract -> Project (Project within Contract within Client)Based on 2 different Hierarchies from above - here are a couple of use cases:


Country = "USA", Work Group = "Network Infrastructure", Project Team = all teams
Country = "USA", Work Group = all work groups

Client = "Client A", Contract = "2007-2008 Maint", Project = "Accounts Payable Maintenance"
Client = "Client A", Contract = "2007-2008 Maint", Project = all
Client = "Client A", Contract = allI am totally stuck on:


How to implement the data interface (Stored Procs) to the Reports
Implement the business logic to handle the different hierarchies & different number of levelsI did get help earlier in this forum for how to handle a parameter having a specific value or NULL value (to select "all")
(WorkGroup = @argWorkGroup OR @argWorkGrop is NULL)

Any Ideas? Should I be doing this in SQL Statements or should I be looking to use Analysis Services.

Thanks for all your help!

Update More Than 2 Columns..

Nov 10, 2007

Hi,I have made the code to update more than 2 columns..It is a bad syntax, could someone help me improve my syntax?Code:   command.CommandText = "UPDATE Items SET (Quantityavailable,numtaken) = (Quantityavailable - @qty,numtaken + @qty) WHERE productID=@productID";  command.Parameters.Add("@qty", TextBox1.Text);  command.Parameters.Add("@productID", labid.Text); command.ExecuteNonQuery(); The idea is to update Quantityavailable column by taking away the @qty value, and update numtaken column by adding the @qty column.It says there is a syntax error near '('. Thanks if someone can help,Jon

Only Update Changed Columns

Aug 15, 2006

I have a stored procedure that inserts values into five columns of atable. I need another stored procedure that will allow the user to passone or more of those parameters and update only the column for the datathat was passed. In other words, the update may only have one or two ofthe parameters that was originally provided in the insert. Therefore, Ido not want to update the columns that did not change. What is theproper way to handle this situation?

Update Only Changed Columns

Sep 25, 2007

i there,

I've got a problem With updates on a Table.

I want to update only the Columns which are different to the values of my update-Statement.

One of the problems is an update trigger , which is fired on all update statements.
I want the trigger to be fired only when there are real changes.
Of course i can retrospectively check if there was a real, but i can't devide the real updatet colums from the non changed values. I know there is a statement like RowsUpdated but it doesn't work that way. It indicates also the non changed columns. To lock the row pessimistic read and compare the contents before update is also no option for me.

Is there any command to perform this in a smart way? Or should it be suggested for the next version of SQL-Server like "UPDATE CHANGES MY_TABLENAME SET MY_COLUMN= ... "

thanks in advance
Raimund

UPDATE Column In Table1 From 2 Columns...

Jan 22, 2007

Hey ya'll...
I need to create a query that I can run that will allow me to essentially take the first initial and last name and combine them from two columns in one table and update one column with that new data in another table. Example of need:
UPDATE tblLogin.UserName with (first character(tblEmployee.FName)+(tblEmployee.LName)) WHERE tblLogin.EmployeeID = tblEmployee.EmployeeID.
That was TOTALLY pseudo code and I know I'll need a join statement in there somewhere. Both tables reside on the same database, such as this:
dbEMPLOYEE (Database)--> tblLogin (Table)----> UserName (Column)--> tblEmployee (Table)----> FName (Column)----> LName (Column)
Any help would be GREATLY appreciated! Hopefully something soon - this was handed to me a few minutes ago and I have a few minutes to get it done.iSheahan

Convert Money Columns To Update?

Apr 13, 2007

 Hi Guys
I need your help again, I am try to update several columns and the data type is 'money'.
Below is the code I have used:
 UPDATE CAT_Products SET
UnitCost ='10.00',UnitCost2 = '10.00',UnitCost3 = '10.00',UnitCost4 = '10.00',UnitCost5 = '10.00',UnitCost6 =  '10.00'
WHERE ProductCode = '0008'
But it will not update, instead I get this error:
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
>[Error] Script lines: 1-9 -------------------------- Disallowed implicit conversion from data type varchar to data type money, table 'dbo.CAT_Products', column 'UnitCost'. Use the CONVERT function to run this query. 
 More exceptions ... Disallowed implicit conversion from data type varchar to data type money, table '.dbo.CAT_Products', column 'UnitCost2'. Use the CONVERT function to run this query.
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
The error message indicates that I need to use the convert function.  But the columns data type is set at 'money' not 'varcher' .  So do I need to convert data type to 'varcher' in order to update and convert back to data type 'money' when update complete?  Or do I need to indicate in the update statement that data type is already 'money'? I am not sure how I would either. 
Thanks

Update Multiple Columns In One Sql Statements

Nov 2, 2004

I am almost sure I can update variables columns in one select/case type
statement, but having problems working out the syntax.

I have a table with transactions - with tran types as the key.

in this example, types = A,B,C ,D.

in this first example I am updating the sum of QTY to value t_A based on
tran types =A.

can I perform sub query/case to update with the same where clause
but for types B,C and D?? I also have to insert for specific lot numbers each sum values.



Create table #t_reconcile(
t_lot_number int not null,
t_A float,
t_B float,
t_C float,
t_D float)


insert #t_reconcile

select t.lot_number, sum(t.qty)
from i , t
where i._id = t.event_id
i.transaction_type = 'A'
group by t.lot_number
order by t.lot_number

Simple SQL To Update Specific Columns

How To UPDATE A Variable Number Of Columns

Feb 6, 2008



Hi, I need to update a number of columns in a number of tables - I just don't know how many. In this case, I am updating all varchar fields and nvarchar fields to be converted to lower case. The problem is that the table structure is amended over time as columns are added programmatically, so I do not know which tables have which columns and if so which of them are varchars.

I can get a table of which fields I need to update using:

SELECT TABLE_NAME, COLUMN_NAME, ORDINAL_POSITION, DATA_TYPE
INTO tblTempLCase
FROM information_schema.columns
WHERE DATA_TYPE LIKE '%varchar'

and I can do the update with UPDATE tblxxx SET column = LOWER(column)

But what I don't know is how to step through my temporary table and do the updates. I can do it in ASP.NET, but that involves pushing commands and data between ASP and SQL, and will be too slow. How do I do it in SQL?

Thanks,

Dave Stephens

How To UPDATE A Variable Number Of Columns

Feb 6, 2008

Hi,



I need to update a number of columns within a number of tables - I just don't know how many. In this case, I want to convert all varchar and nvarchar columns to lower-case versions of themselves. The problem is that the table structure is changed programatically, and so at any point in time I cannot be certain what fields are in which table, and what data type they are.



I know that I can get a lit of columns using:



SELECT TABLE_NAME, COLUMN_NAME, ORDINAL_POSITION, DATA_TYPE
INTO tblTempLCase
FROM information_schema.columns
WHERE DATA_TYPE LIKE '%varchar'


and do the update using:



UPDATE tblABCDE SET column = LOWER(column).



In ASP.NET I can pull in this temporary table using a SQL Data Adapter, and then step through the records to formulate the UPDATE statements and execute them all. However, I hope that this is possible in SQL too, so that I do not have to keep firing data/commands between ASP and SQL, as it should be quicker, and is also neater.



If so, how do you do it?



Thanks,

How To Update A Column With The Sum Of Two Columns In A Table

May 9, 2008



I have a simple question that is more about performance on my code for updating a column with the sum of two columns:

Example

Table = dbo.adding

c1 c2 c3Sum
1 2
3 5
4 6

Now if I just simple write

Update dbo.adding
set c3SUM = c1 + c2

This works, but there is a null in c1 or c2 then I know I can write this:


if exists (select * from dbo.adding where c1 is NULL)

Update dbo.adding

set c1 = '0', c3SUM = '0' + c2 where c1 is NULL

if exists (select * from dbo.adding where c2 is NULL)

Update dbo.adding

set c2 = '0', equals = c1 + '0' where c2 is NULL

Update dbo.adding

set c3SUM = c1 + c2

This works as well, but I am not sure how perficient it is being that from my understanding the code will evaluate the table three times and update it based on the criteria. If the table consists of 100,000 rows then this might not be a good solution

Is there a more proficient way to do this... I personally try to as little coding as possible to help increase performance. I know I can make this very complex and declare variables and put everything in a loop, but I personally think that would be less profient..
