Reeeeeally Easy For You Guys!
Jan 5, 2004
can someone post me an example trigger where.. inserting a new record in one table, creates a new record in another table with a new unique identifier incrementing by 1 from the last record.
so that I can edit it to suit my own work like:
eg. when I insert new person into people table, using a person_no as key.
= creates new pay record in pay table ith a pay_id as key like '0004' 1 more than the last record if it was '0003', and then adds that new person_no to the record for reference.
I know this is a really easy trigger, but it would be my first! Any example to edit would be great! thanks in advance

Hi all!
Steve suggested I post my question here because this is where all the "experts" reside who like a little challenge. I'll simplify my problem down to two example tables with two fields each for the purpose of solving this "hard part". My only requirement for the solution is that it has to be a SQL only solution (no stored procs) as my client can only run Access - yuck...
Here's the deal. There are two tables, PEOPLE and JOBS. They look like this:
PEOPLE Table:
ID NAME
------ ------
1 Adam
2 Bill
3 Carl
4 Dave
JOBS Table:
DESC ASSIGNED_TO
----- -----------
Clean 1
Wash 2,3
Dry 2
Polish 1,3,4
I want to report which people are assigned to which jobs as shown. One line per job with the names concatenated with commas in between:
Clean Adam
Wash Bill,Carl
Dry Bill
Polish Adam,Carl,Dave
All four fields are TEXT fields in this design, but they don't have to be. I have full control over the database, fields, types, etc. If there's a better way then just suggest it. As you can see, the "ASSIGNED_TO" field is a concatenation of the IDs. Goal is just to report the DESC and people's NAMEs.
How about it? Any slick way of doing this? Played around with using SubQueries, IIF, LIKE on ID and ASSIGNED_TO, and came close but never got it all.
I appreciate any tips or suggestions. Thanks a bunch!
John

I have a table with values
id diff
1 5
2 10
5 5
6 15
7 20
8 10
10 5
11 10
12 15
I need a sum of such records whose id are continous.I mean the output should be
id sum
2 15
8 50
12 25
Id 1 & 2 are continous so it is added.But after 2 the next number is not 3 so it wont be in the sum of 1 & 2.From 5 to 8 numbers are continous so those diff are added & so on.

Ok i've tried everything setting table collation to cyrillic setting the whole table language settings to Russian nothing works-i can only save ?????? instead of Russian symvols.(yes datatype is ntext not just text) I can directly input Russian letters from EMS SQL manager, and it will be ok, and i can even read it on my pages. But even if i try to execute SQL command through EMS manager (as opposite to just typing in the data) it will give me ????? again. If I save my ASP.net page in unicode it will give me ?? with some weird ` types symbols-but 70% of symbols would still be ????. I have already spend 45 hours googling and browsing forums but i still cannot solve it! I am so frustrated!
MS SQL Server 2005 Framework 2 ASP.net code looks like Win XP sp2
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
using System.Data.Odbc;
using System.Data.SqlClient;
public partial class registration : System.Web.UI.Page
{
private const string ConnStr = "server=(local);database=main;Trusted_Connection=yes";
private const string ConnStr = "server=(local);database=main;Trusted_Connection=yes";
private void Page_Load(object sender, System.EventArgs e)
{
SqlConnection myConnection = new SqlConnection("server=(local);database=main;Trusted_Connection=yes;");
///ыуаыпвараеоеаореавп is russian random letters
SqlCommand myCommand = new SqlCommand("UPDATE quest SET Name='ыуаыпвараеоеаореавп' WHERE id=1", myConnection);
myConnection.Open();
SqlDataReader dr = myCommand.ExecuteReader();
myConnection.Close();
if i manually stop the script here and look at my dr variable i will see exactly sql command that i wrote (with no ????) but after execution in my database it is still ??????????????????????????????
Best Regards

i use a teltonika t-modem gsm modem..
it's quite new actually and it is connected to my PC thru a usb port..
my problem now is that
i can,t seem to get the hang in storing received messages in
my SQL database..
the code goes like this..
a receive button is clicked to generate an instance
where all SMS sent to my sim card would then be accessed by my gsm modem..
private void btnReceive_Click(object sender, EventArgs e)
{
ListViewItem Component;
Cursor c = Cursor.Current;
Cursor.Current = Cursors.WaitCursor;
listView1.Items.Clear();
btnReceive.Enabled = false;
objGsmIn.Device = cmbDevice.SelectedItem.ToString();
objGsmIn.LogFile = txtLogging.Text;
if (cmbDeviceSpeed.SelectedIndex == 0)
{
objGsmIn.DeviceSpeed = 0;
}
else
{
objGsmIn.DeviceSpeed = System.Int32.Parse(cmbDeviceSpeed.Text);
}
objGsmIn.Storage = fMsgStore.MsgStorage;
if (fMsgStore.DelMsg == true)
{//deletes your message after receiving
objGsmIn.DeleteAfterReceive = 1;
}
objGsmIn.Receive(); //this checks your new incoming messages
if (objGsmIn.LastError == 0)
{
objGsmIn.GetFirstMessage();
while (objGsmIn.LastError == 0)
{
//continously receive all messages..
Component = listView1.Items.Add(objGsmIn.MessageSender);
Component.SubItems.Add(objGsmIn.MessageData);
objGsmIn.GetNextMessage();
}
txtResults.Text = "Messages Successfully Received..";
}
else
{
//error in message receiving process..
txtResults.Text = "Error " + objGsmIn.LastError + "(" + objGsmIn.GetErrorDescription(objGsmIn.LastError) + ")";
}
btnReceive.Enabled = true;
Cursor.Current = c;
}
now my problem is that i cant figure out where i would place my stored procedure
in storing those messages to my database..
the problem is that..
if i place my stored procedure on the 1st "IF" statement..
it will only save my 1st incoming message..
but another thing is that if i put it under my "WHILE" statement..
dont you think that it will continiously loop?
meaning to say that the next tym i tried to access all my received messages
it would definitely store all the previously read messages again to my database..
which then creates multiple copies of my previously stored messages again and again
well i hope you get the gist of what i mean..
its quite complicated to explain..
but then again thanks a lot for taking notice on my post regarding this..
thanks!!^_^
another thing..i used the active xperts c# application in order to
create this application..

Finding myself in a bit of a lull at work, I'm trying to create some template packages / solutions, encapsulating some of the best practices that get discussed on here.
I'm thinking about passing configurations from Parent to Child packages, something we all must do on a regular basis. I've always done this a particular way, without thinking too much about it, but I'm not sure if this way is the best. I'd be interested in your opinions.
Scenario:
Parent.dtsx calls Child1.dtsx, Child2.dtsx etc, using Execute Package Task.
Parent has variable Source, and variable Destination, populated from a configuration (my preference is SQL table, but whatever).
These variables are ultimately used to populate the ConnectionString property of the source and destination Connection Managers of the Child packages.
Here's the question: Is it better for the Child packages to look up to their parent, and inherit the values of these variables through Parent Package Configurations, or to look directly to the configuration, and pick them up from there? Or does it not matter?
I tend to assign lots and lots of variables in Parent.dtsx, and pull them down into Child.dtsx with Parent Package Configs, but I'm thinking "is this good/bad/unimportant?"

Reading about avoiding deadlocks in SQL, I have found different opnions about whether using or not NOLOCK/ROWLOCK hints on SELECT/UPDATE/DELETE statements. I have several applications executing transactions on the same databases and tables, including inserts, updates and deletes. I wonder if by using NOLOCK/ROWLOCK I could decrease the chances of having deadlocks. At least using ROWLOCK on my update statements?. I just need some advice here.
Regards.

I have another question guys I need to send reports to different departments using sql. would this be the xp_sendmail function in sql. Can this be made into a stored procedure? What I'm going to do is make some reports which will constantly be updated with a query. These reports need to be emailed to differnt departments every 2 weeks. Is there a trigger or stored procedure I can setup through sql to do this? Does that make any sense??

In the previous versions it is "01-Jan-1753"

Hey,
I have a asp.net 2.0 app that has a sql server express backend. I have been scratching my head for weeks trying to find a good wasy to encrypt my connection string. I store the string in web.config (which in itself is in theory "safe" because it's not servable) and I have scoured the web to try to find a simple way to encrypt the connection string. Even using user store would require running aspreg_iis.exe on the host with a command prompt (which clearly I cannot do). It seems that everyone's solution requires running a command prompt executable on the server.
So I am left to wonder what everyone else does. I am not comfortable using just the web.config because a determined hacker could get to that info. Then again, a determined hacker could get into any system , I guess. There are no credit card #'s stored in this app, but in theory there must be a way. I run all access to the db through stored procedures with permissions, for whatever it's worth.
Thanks in advance!
David

Why don't you folks (SQL SERVER Management Studio Team or SQL SERVER Database Engine Team) provide an option by using which I would be in a position to know what all the other objects are depended on a selected object and vice versa. That means:
When I select a Table within the SQL SERVER Management Studio if there is an option for understanding "Which all the objects (tables or views) it is depended on (I mean Foreign key and etc... kind of relations) and also Which all the objects (Tables, Views, Stored Procedures and etc...) are using this table", It would be of great help for all developers.
I can be contacted over kotis@microsoft.com

I'm banging my head against the wall. It's probably pretty simple so here goes...
I have a form that supposed to add records to a table on the database. I'm pretty sure I have the dataAdapter and Dataset set right but when I add a record, it complains that the primary key can’t be null. I’ve tried different things, including removing those fields and variables from the stored Proc, changing the Identity Properties of the Table, changing the AutoIncrement settings on the Dataset for that field, but all give me different errors. Nothing actually makes it work. This database has many records in it and the Primary key is a decimal field that starts at 5, then next was 10, then 28, then it started getting consecutive after 110. (111, 112, 113, etc.) (I'm porting over an old database to a new web site, so I'm somewhat contrained by the database.)
I guess my question is for adding records in to a database that has a primary unique key constraint. Certainly this is a pretty common thing. Obviously I do not want users to enter that in themselves, I thought it should simply autocreate/autonumber. So what is the best procedure and gotcha’s I need to watch out for?

//First query in transaction
pre_query = "Delete from Menu where spec_name="

+ spec_name_array[i].Text.ToString()
+"','"
+ spec_desc_array[i].Text.ToString()
+"','"
+spec_price_array[i].Text.ToString()
+"',1)";
SqlCommand comm = new SqlCommand(pre_query,conn);
//Setup the command to handle transaction
comm.Transaction = trans;
//Execute first query
comm.ExecuteNonQuery();
//Add in second query
comm.CommandText = query;
//Execute second query
comm.ExecuteNonQuery();
trans.Commit();
}
catch(SqlException ex)
{
com_label.Text = "Submission Not complete, did you forget the date or something else?";
//Undo all queries
trans.Rollback();
}
finally
{
conn.Close();

This may not be the right place for this post...but my head is hurting and I can't think right now.
I have a SQL table of users. Each record has a required 'Birthdate' field. I'd like to order this by the days left till the give birthday, keeping in mind that the year may be 1980 or their birthday might have been 2 weeks ago.
Can someone cure my headache?

I have written 2 custom connection mgr€™s.
One connects the data from an oracle source
One connects so I can put the data on a sql server.
These both work well and it makes it a lot easier across development, test, production.
But now I would like a good way to do this
I have 10 tables to copy from oracle. The only difference is just the name of the table.
static string[] g_tables =
{
"table_name_1",
"table_name_2",
"table_name_3",
€¦
};
foreach (string str_table in g_tables)
{
Oracle.DataAccess.Client.OracleCommand OracleCommand = new Oracle.DataAccess.Client.OracleCommand
(
"select * from " + str_table,
OracleConnection
);
Oracle.DataAccess.Client.OracleDataReader OracleDataReader =
OracleCommand.ExecuteReader();
// dump out to raw file destination
}
I understand there are some pieces left out but that is the basic idea. It seems like I€™m going to have write custom pieces for each step.
It does not seem like there is any advantage to using SSIS. Should I give up now and stick to writing windows services for stuff like this?
I could just write a specific piece for each table but the only difference is the table name.

scenario I have 2 tables one is called "Site" which contains columns ID, Address1, Address2,City,StateID,ZipCode and the second table is called "State" which contains columns ID,Name,Abbreviation. I am looking to make a view that contains all the sites with the state inner joined on stateid to make my all my other queries easier. That is so I can just select from the view without having to do the inner join on the state. My question is when a new record is added to table Site do I have "recreate"/update the view?

I need to create a SQL statement that produces all category items where that ROW's products_ID is not found in ANY product_local in the table. So in the table above only the category BASE and LEAF would be printed because their products_ID are not found in any product_local in the table.
