Why don't you make the ID a primary key and set its Identity to true, then it will auto increment by 1.
|
|

|

the problem is that I'm using this database via a WCF-Service.
so multiuser accessibility is the main problem.
If 2 users are saving their date at the same, who would this be solved with assigning the IDs?
so I've tryed this with MAX().
I really don't know how it would act with the IDs.
I would be grateful if someone could tell me if this could work like you say.

I use the following construct in my system:
INSERT INTO myTable(ID, Employee, Project, Date, ...)
SELECT MAX(ID)+1, @Employee, @Project, @Date, ...
FROM myTable;
and it works fine.
Hope it helps.

Given it was running with the right permissions, you could. I don't see why you'd want to however. Given that you could accomplish the same through the use of temporary tables/in-memory tables, what are you trying to do here?

to validate data before inserting to a column can be done using CHECK constraint.
but, you are looking for comparing data from multiple columns and then validate the same. I've not sure whether is possible using constraint. however you can write a TRIGGER for validating.

I am posting the code.....please check if it works or not......here the logic is........
check whether duplicate record exist or not before inserting records in table.....
i am only posting the code to check the duplicate record in table.....
this SQL will find record if the number ,you are going to insert, exist in table between fromSerial and toSerial
Dim fS as Integer = 10
Dim tS as Integer = 20<br />
Dim myConnection As System.Data.OleDb.OleDbConnection<br />
Dim ds As DataSet<br />
Dim da As OleDbDataAdapter <br />
<br />
Dim strConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" <br />
& myDatabaseath & ";Persist Security Info=False" <br />
<br />
Dim sqlDuplicate As String = "SELECT vndrCode FROM myTable WHERE <br />
"serialFrom > " & fS & " " & _<br />
"And serialFrom < " & tS & " " & _<br />
"Or serialTo > " & fS & " " & _<br />
"And serialTo < " & tS & " " & _<br />
"Or serialFrom < " & fS & " " & _<br />
"And serialTo > " & tS & " " & _<br />
"Or serialFrom < " & fS & " " & _<br />
"And serialTo > " & tS & " " & _<br />
"Or serialFrom < " & fS & " " & _<br />
"And serialTo > " & fS & " " & _<br />
"Or serialFrom < " & tS & " " & _<br />
"And serialTo > " & tS & " )"<br />
<br />
<br />
// Set up connection<br />
<br />
If Not myConnection Is Nothing Then<br />
If myConnection.State = ConnectionState.Open Then <br />
myConnection.Close()<br />
myConnection = New OleDbConnection(strConn)<br />
myConnection.Open()<br />
Else<br />
myConnection = New OleDbConnection(strConn)<br />
myConnection.Open()<br />
End If<br />
<br />
// Bring records<br />
<br />
da = New OleDbDataAdapter(sqlDuplicate , myConnection)<br />
ds = New DataSet<br />
da.Fill(ds, "Tablename")<br />
<br />
// Check if duplicate record exist <br />
<br />
If ds.Tables(0).Rows.Count = 0 Then : Return 0 //Duplicate Record doesn't exist<br />
Else : Return 1 //Duplicate Record exists<br />
End If
Last of all I dont think this code is very smart .....looking for better answer

Can some one let me know what would be the best way to authenticate a client that runs on a different AD domain from the domain where the SQL server runs..
Is there some way to use Trusted connection in this scenario
NaReN

If you are talking about a web app, yes there is. You set the identity of the app pool your web app is running in as a domain user account that has the correct rights in sql server. Then your connection string for your web app can use trusted connection.
If you are talking about a windows app, I am not sure if it is possible or not.
Hope that helps.

for Scheduled Jobs ...
in SQL Server Enterprise Manager
Managenemt -> SQL Server Agent - > Jobs.
To my knowledge it is possible to schedule and run SQL commands only.
for executing other applications on scheduled interavals ...
1. write an application and schedule it in windows scheduler so that it
executes on regular intervals
or
2. write a service and configure for automatic startup.

Hi
In my database I have two tables with the same structure (columns, data types, etc).
How would I copy or move specific records from the one table to the other one using Transact-SQL in a stored procedure?
Thanks.
Kobus

|
|
do u mean to copy the data from one table to another table ?or u want to move only specific records?
|
|
|
|
|
I would just like to be able to copy/move specific records, for example those records where UserIndex = 123.
Kobus
|
|
|
|
|
INSERT INTO tblA SELECT * FROM tblB WHERE userIndex = 123

Thanks KP
Exactly what I was looking for.
Kobus
|
|
|
|
|
|
INSERT INTO <table1> SELECT * FROM <table2> [WHERE <condition>]
this will allow to select data from one table and insert into another.

I get several EDI Files from vendors that have small square at the en of the file on the last line, if I don’t delete them before running my stored procedure I get unexpected end of file error. Anyone know how to make the procedure ignore this?
Brian

Hi Brian
Most text editors show a small square to indicate that there is a non-printable control character.
If you can identify what the control-character is (I normally use a Unix hex dump) then you can use
REPLACE(MyColumn, CHAR(n), '') to get rid of it (where "n" is the character number). The most likely control-characters are CHAR(0) [ASCII NUL] and CHAR(26) [ASCII EOF].
Hope that helps.
