Hi
Are you concatenating values of multiple fields in your procedure? In that case, if one of the fields is null, concatenating with any other field (even if the second does contain some value) will result in a null.

Hi All,
Could you please let me know how to set up a trigger for the following senario?
How could i setup a trigger to populate a back_up table every time i do an Insert on the master Table.
//--------------------------------------------------------------
INSERT INTO [repor32].[dbo].[Master_table] SELECT * FROM [repor32].[dbo].[Back_up] WHERE [ADETDATE] NOT IN (SELECT [ADETDATE] FROM [repor32].[dbo].[Master_table])
Thank you

I'm not sure that I understand the scenario here. Is this the query that you will use in the trigger? or is the query that makes the insert in the master?
amyway, check the CREATE TRIGGER[^] syntax from msdn

I have a SQL question if any of you have time:
I want to do an update using two tables. I used to know how to do this but I've forgotten.
Put simply I havw two tables, Cars and UnMatched
Cars:
ModelCode number (Primary Key)
FuelType text
UnMatched:
ID number (Primary Key)
FuelType text
Cars has lots of rows, Unmatched has less.
I want to update Cars setting the FuelType to the value of FuelType in Unmatched, where the ModelCode in Cars = the ID in UnMatched.
So for example if Cars had the following Rows:
10 ""
11 ""
12 ""
13 ""
And UnMatched had these rows
11 "PETROL"
13 "DIESEL"
14 "HYBRID"
You'd end up with Cars being
10 ""
11 "PETROL"
12 ""
13 "DIESEL"
I know it's some kind of correlated subquery but I can't remember what it is.
This is on an Access database but I'd imagine it would be the same on others.
Thanks - Ben

In SQL Server you would do
UPDATE Cars
SET FuelType = UnMatched.FuelType
FROM UnMatched
WHERE ModelCode = UnMatched.ID It acts rather like a join but you don't qualify the names of columns for the table you're updating with the name of the table.
However, I don't think this is supported by Jet.

This will show the result in the required format, but it does not convert it to datetime:
Select substring(fieldname,1,2) +':'+ substring(fieldname,3,2)

Hi Friends,
How are you,i have one doubt,i made a wrong update to my table and now i want to rollback the transcation,i have used sql query analyser.
Kindly please tell me the solution to rollback.
Thanks & Regards
Senthil Kumar

Do you have any backups before the change?
If no, I'm afraid this won't be possible.
|
|
|
|

You're misunderstanding what a transaction is.
You can only rollback the transaction if the transaction hasn't been commited yet. If you used the Query Analyer to make this change using an UPDATE query, it's done. The transaction was started, the change was made, and the transation automatically committed when you clicked on the Execute button.
AFAIK, there is no way to roll this back without restoring the database from backup.

I have to tables MASTER_ACCOUNTS and DEPOT_ACCOUNTS. I need to UPDATE the MASTER_ACCOUNTS table with the values in DEPOT_ACCOUNTS where the ACCOUNTID columns match. Both table structures are the same.
Not sure how I should achieve this, so any help would be appreicated.
Thanks

The long way
update master_accounts
set master_accounts.a = de.a,master_accounts.b = de.b,etc...
from master_accounts
join depot_accounts de
on master_accounts.acountid = de.accountid
Or if you are feeling like throwing caution to the wind:
Another thing you can do is delete all the rows in master_accounts that have a matching accountid in depot_accounts.
Keep a record of these accountids in a temp table first.
Then insert all the rows in depot_accounts that correspond, to the accountids in the temp table, into master_accounts.
Since the table structures are the same this will mean that you do not need to type all those = statements.
You always pass failure on the way to success.

I was hoping there would be a better, more eligent way, like the INSERT INTO aTable SELECT * FROM bTable.
Ho well! Thanks for educating me.

You would have the issue of duplicated records if you ran the query this way.
Instead of insert you would have to use update and this requires column names to be specified.
This is because insert does not replace records it appends records.
Although SQL is a declarative language you still need to do a lot of work in writing the queries 
Microsoft are apparently developing new declarative languages so in the future things may be easier...

Hi I need to write a function in SQL that returns the date of the previous Monday, for example:
if today is Tuesday thru Sunday then get previous Monday
else if today is Monday get todays date.
Any help would be appreciated.
Thanks.
|

I actually got this to work so I thot I'd share...
ALTER FUNCTION [dbo].[fn_GetMonday]
( @pInputDate DATETIME )
RETURNS DATETIME
BEGIN
DECLARE @Result DATETIME
SET @pInputDate = CONVERT(VARCHAR(10), @pInputDate, 111)
IF DATENAME(dw, @pInputDate) = 'Sunday'
BEGIN
SET @Result = DATEADD(DD, -6, @pInputDate)
END
ELSE
SET @Result = DATEADD(DD, -DATEPART(DW, @pInputDate) + 2, @pInputDate)
RETURN @Result
END
|
|
|
|
|
I am no expert and there may be a better way of doing it, but have a look at DATEPART and DATEADD functions along with a WHILE loop.
DECLARE @MyDate DATETIME<br />
SET @MyDate = GETDATE()<br />
WHILE (DATEPART(dw, @MyDate)) <> 'Monday'<br />
BEGIN<br />
SET @MyDate = DATEADD(day, -1, @MyDate)<br />
END
MyDate should now contain the date of the previous monday or today's date if today is a Monday.

Wrong forum, try posting your question in the C# forum. Also it would be better if you provided a descriptive subject line, rather than 'Hi' or 'Hello' or 'Urgent' etc.

Hi....
you need to change the below lines...
mon***z wrote: lst_emp.DataTextField=objds.Tables[0].Columns["txtval"].ToString();
lst_emp.DataValueField=objds.Tables[0].Columns["emp_id"].ToString();
to......
lst_emp.DataTextField = "txtval";<br />
lst_emp.DataValueField = "emp_id";

DataSet objds=new DataSet();<br />
adp.Fill(objds); <br />
<br />
lst_emp.DataSource = objds.Tables[0].DefaultView<br />
cmbBookFrom.ValueMember = "emp_id"<br />
cmbBookFrom.DisplayMember = "txtval"
i think this will make your life easier

I have the following INSERT command which works well, but I need to limit what is inserted.
INSERT INTO SalesLogix.sysdba.Account SELECT * FROM DONCASTER4.SalesLogix.sysdba.Account
FYI: DONCASTER4 is a linked server.
What I need to do is only insert records where the value of the AccountId column of the source table does not already exist in the destination table.
Both tables are identical and both servers are MS SQL Server 2005.
Your help on this is appreicated.
