Does SQL Server have an autonumber datatype which will increment when adding record

YES.
CREATE TABLE tblA(
AutoID decimal(18, 0) NOT NULL IDENTITY (1, 1),
Col2 varchar(10)
)
|
|
|
|
|
yes that s IDENTITY
See the example :
CREATE TABLE Emp (EMPID int IDENTITY (1, 1) NOT NULL ,EMPNAME VARCHAR(20))
Above this examble Identity is like an auto increment.
The Parameters (1,1) represents Start Number, Increment Number
this example starts 1 and next incremented by 1

Hi, sometimes when I execute a procedure, it quits in no time:
echo "execute procedure ro_main_tp_oc('ATS','EY','N')" | dbaccess prds
Database selected.
Routine executed.
Database closed.
I heard it's because some procedure was blocked and locks other procedures. How shall I check and resolve it?
I am using HP unix, informix.
Thanks!

There aren't very many Informix guys on this forum - its mostly SQL Server, Access, Oracle and MySQL.
I would try using dbaccess to run the command interactively to see if you get any better clue about what is happening.
Blocking and locks would normally result in a procedure being really slow. If there is a problem then I would guess that the procedure contains:- A "set lock mode" or "set current lock timeout" statement that tells Informix to throw an error if it encounters a locked record (or the database has been configured with a "locktimeout" parameter).
- An update/delete statement or a "for-update" cursor statement.
- If no error message is being displayed then I would expect that the resulting timeout error is being swallowed a "whenever error" clause.
If there was a problem with blocking then I would have expected an error message to be displayed (especially given that Informix is such a mature product). Are you sure that the procedure is having problems?
Hope that helps. I haven't done Informix for a reeeeeeally long time.

sir,
I have a table which is having duplicate and some distinct records. Please can anybody please tell me the SQL-Server-2000 query to get only the duplicate records.
Means I dont need those records, which are not duplicate, but I need to print only those records which are duplicate. Thank you.

I've tested the query on SQL server 2000
i'm getting proper output fetching proper data
i.e. i've a table in that new columns have duplicate data and other unique
when i include only duplicate data columns in the table i'm getting those rows which is duplicated that too when used ">10" returns those having 11 or more times repeated and when used ">3" returns those repeated 4 or more times and so on.
Regards
KP

KP lets suppose this is my table structure, with a, b, c are columns. Now I would like to print only those columns which are duplicate. And by using the query its not printing any thing.
* SELECT a, b, c FROM SampleTable GROUP BY a, b, c HAVING COUNT(*) > 1 *
But if I give <=1 or < or = its giving atleast some values.
And even if I give this also * SELECT a, b FROM SampleTable GROUP BY a, b HAVING COUNT(*) > 1 *
And * SELECT a, b FROM SampleTable GROUP BY a, b HAVING COUNT(a) > 1 * its also not giving me any thing.
Thank you.

As per the sample data combination all three columns are unique. no duplication
however, separatly each column has duplicate values.
query given by me will list if combination three columns are repeated.
for example
AA 12 1
BB tyt 12
AA 12 1
CC tr mn
CC df tr
output would be
AA 12 1
rows with BB & CC will not be listed as they re present only once.

Hello,
I've created the following stored procedure:
<br />
CREATE PROCEDURE SOM_RO_ISVALIDPRJID <br />
@strProjectID varchar(32)<br />
AS<br />
BEGIN<br />
DECLARE @intPrjID int<br />
<br />
SET NOCOUNT ON;<br />
@intPrjID = (SELECT COUNT(*) FROM dbo.tbl_projects_main WHERE prj_custom_id = @strProjectID)<br />
END<br />
IF (@intPrjID = 0)<br />
RETURN 0<br />
ELSE<br />
RETURN 1<br />
GO<br />
I keep getting the error:
Incorrect syntax near '@intPrjID' at line 8.
The line it is referring to is where I have @intPrjID = (SELECT ...)

replace it with:
SELECT @intPrjID = COUNT(*) FROM dbo.tbl_projects_main WHERE prj_custom_id = @strProjectID
or with
Set @intPrjID = (SELECT COUNT(*) FROM dbo.tbl_projects_main WHERE prj_custom_id = @strProjectID)
Wout Louwers

along with the two methods specified by Wout Louwers
also this can be used
SELECT @intPrjID = (SELECT COUNT(*) FROM dbo.tbl_projects_main WHERE prj_custom_id = @strProjectID)
(i.e. instead of SET, SELECT can be used.)

Someone mentioned something about docking or linking tables into Access. What does that mean? I believe linking means accessing a table through Access but I dont know about docking.

Hi,
I have 2 problems:
a) cannot connect to my sql table eventhough I used the same userid and pwd in Query Analyzer . I keep getting 'Not associated with a trusted SQL Server connection'
b) which date format I have to use to lookup for a row (from a search textbox)
Here is my code:
<%@ Import Namespace="System.Web.UI.WebControls"%>
<%@ Import Namespace="System.Data.SQLclient"%>
<%@ Import Namespace="System.Data"%>
<%@ Import Namespace="System.Data.OleDb" %>
Sub LookupDate (ByVal s As Object, ByVal e As EventArgs)
Dim myconn As SqlConnection
Dim strSelect As String
Dim cmdSelect As SqlCommand
myconn = New SqlConnection("server=localhost;UID=myUSERID;PWD=myPASSWRD;Database=myDBNAME")
strSelect = "SELECT [col1], [col2], [myTime] FROM [myTableName] WHERE myTime = @myTime ORDER BY [myTime] desc "
cmdSelect = New SqlCommand(strSelect, myconn)
cmdSelect.Parameters.AddWithValue("@myTime", textMyTime.Text)
myconn.Open()
lblVal.Text = cmdSelect.ExecuteScalar()
'lblVal.DataBind()
myconn.Close()
End Sub
<title>title
Date Lookup
<asp:textbox id="textMyTime" runat="server">
<asp:button text="search" id="search" onclick="LookupDate" runat="server">
<asp:label id="lblVal" enableviewstate="False" runat="server">

For some reason i got cutoff so here is my question again:
<%@ Import Namespace="System.Web.UI.WebControls"%>
<%@ Import Namespace="System.Data.SQLclient"%>
<%@ Import Namespace="System.Data"%>
<%@ Import Namespace="System.Data.OleDb" %>
Sub LookupDate (ByVal s As Object, ByVal e As EventArgs)
Dim myconn As SqlConnection
Dim strSelect As String
Dim cmdSelect As SqlCommand
conValid = New SqlConnection("server=localhost;UID=myUSERID; PWD=myPASSWRD;Database=myDBNAME")
strSelect = "SELECT [col1], [col2], [myTime] FROM [myTableName] WHERE myTime = @myTime ORDER BY [myTime] desc "
cmdSelect = New SqlCommand(strSelect, myconn)
cmdSelect.Parameters.AddWithValue("@myTime", textMyTime.Text)
myconn.Open()
lblVal.Text = cmdSelect.ExecuteScalar()
'lblVal.DataBind()
myconn.Close()
End Sub
<title>title
Date Lookup
<asp:textbox id="textMyTime" runat="server">
<asp:button text="search" id="search" onclick="LookupDate" runat="server">
<asp:label id="lblVal" enableviewstate="False" runat="server">

When you start Query Analyzer, tick the "Windows Authentication" option. You should need to input a user ID and Password for a trusted connection.
I would question the data-type of your parameter. If you use a datetime type and cast your text to a datetime variable then you shouldn't have to worry about the format.
Also, you probably should be using ExecuteScalar because your select statement is returning several columns, and looks like you want to return several rows too.

in SQL Analyzer, I was able to connect and login under SQL auth. I also able to login using Window Auth. but my query comes back empty. In another code, I used
<asp:sqldatasource id="SqlDataSource1" runat="server" connectionstring="<%$ ConnectionStrings:dbReMUSConnectionString %>"
="" selectcommand="SELECT .................... ">
on the same db and I had no problem.
I also using vs 2005 and the db is a sql 2000 db
Thanks
