How To Update Columns From Row To Another Row? (thank You)
Jan 31, 2008
assume my Table's Columns looks like below
1 , Annie, History, pass, null
2 , Colin, Math , Pass, null
7 , Annie, History, Fail, 1
11 , Colin, Math , Fail, 2
When Delete
7 , Annie, History, Fail, 1
11 , Colin, Math , Fail, 2
using the last column to check which row is reference with it
so when delete Row 7 which reference with
1 , Annie, History, pass, null
when delete Row 11 which reference with
2 , Colin, Math , Pass, null
if I gooing to delete the row of No7 the result would be
1 , Annie, History, Fail, null
2 , Colin, Math , Pass, 0
11 , Colin, Math , Pass, 0
if I going to delete the row of No11 the result would be
1 , Annie, History, pass, null
2 , Colin, Math , Pass, null
7 , Annie, History, Fail, 1
I think the simply way to explan is
when you delete a row of data , first find out which row is reference with it and then update the row which reference with it
can you teach me how to do it ? wirte this request in Code or useing SQL Script?
thank you

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

Hi
I have to update the incidents table.
The initiator and initdept are two corresponding columns whoes value I have to get from another table Employee where (initiator means Empname and initdept means title)
if i just do
select Empname,title from employee
it gives me correct output while
select initiator,initdept from incidents
It gives the initiator correct but instead of giving the initdept
it gives output as initaiator the out put is given below
initiator initdept
Jeff C. Taylor Jeff C. Taylor
Randy S. Jonas Randy S. Jonas

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?

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

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

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

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

Can you update data from multiple tables in the same UPDATE statement, by joining those tables in a CTE ?
For example, this fails:
DECLARE @UPDCATE_COUNT AS int = 100000;
WITH COMBINED_TABLES AS (
SELECT TOP (@UPDATE_COUNT) T.UpdateID, T.IS_UPDATED, U.[Description]
FROM dbo.Table1 AS U
INNER JOIN dbo.Table2 AS T
[code]....

Hello,I've written an insert trigger to fill in data on 5 columns based on the keyfield column after a record is added to a table. The trigger works fine.But what I also want to do is to write a stored procedure that will updatethe 5 columns for the entire table based on the table key field column.

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

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,
Dave Stephens

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..

Hi,
I'm using sql-2005.
I want to update several columns in different tables whenever an update is happend on specific table. I have a trigger for that which update all the relevant places when it fires.
I want to do this update only if certains columns were changed, otherwise - do anything, to reduce performance.
How Can I know which columns were updated inside the trigger? The tables has many columns and only if 2 of them were changed then I need to update other tables.
Many thanks,

I have 4 rows below in file tblTEST, and I want to be able to transfer the CODE from the MAIN location to the INT location (replacing all existing "A" codes), preceeded by an "I".
ID LOC CODE

I want the result to be:

11 MAIN B

I am stumped as to how to do this - any help or advice would be appreciated.
The only thing I've come up with is:
UPDATE S

FROM tbltest B
LEFT OUTER JOIN tbltest S ON B.id = S.id
WHERE (S.loc = 'INT')
But when I run it, it says "0 rows affected".

Take a Dataflow Task, with an OLEDB Source Component and an OLEDB Destination Component in it. The Source component's Source is stored in a SQLQuery variable, and the Destination component's Destination is stored in a TableName variable. The Dataflow Task is put into an For Loop container.
I just want to do one thing:
In the For Loop, everytime it send a new value to the SQLQuery variable and the TableName variable, then I could use it to transfer many tables in a same logic.
My question is: Really, I could send new values to the variables and make it go. But everytime it says "The external metadata column collection is out of synchronization with the data source columns." Because the external metadata was recorded and not be change automatically everytime of Loop.
How to update the source columns'metadata automatically?

I have a table with 8 columns, I need to update data in multiple columns on this table, this table contains 1 million records, having single update was taking time so I broke the single update into multiple update statements and running multiple update statements in parallel, Each update statement updates different column.
This approach is working fine but I am getting the deadlock error.
Transaction (Process ID 65) was deadlocked on lock | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
I tried with various lock hints but no success.
