Hello,
Would it be possible to open a socket connection and send few data based on an insert TRIGGER?
My client would basically like to send the ID of a product via socket connection when a new product is inserted into the SQL database.
Thanks for your help
Arnold
I just want to know how to create a socket/IP connection using SQL prodecure or function
please help..
thanx
I am new to triggers and surely could use some help.
I can create a trigger to insert related records based on the main tables ID and insert that value into other related tables fine... but...
How do I create a trigger that can insert a record into one table for a columns given value and then insert a record into another table for another given value?
For instance:
New row...
Table1, Column1 (PK) has a value of 101
Table1, Column2 has a value of 'Blue'.
// When a new row is created in Table1 and Column2 has a value of 'Blue'...
I want to insert a new row into Table2 - with Table1 Column1's value.
// Now if Table1, Column2 has a value of 'Red' when the new row was created...
I want to insert a new row into Table3 - with Table1 Column1's value. Not Table2
This has to be inserted into one or the other tables based on column2's value, not both.
Then I want to populate the other related tables (Table4, Table5) with the regular insert statements based on Table1 Column1's value.
This (the conditional part above) has to work with an update to Table1 also.
So if someone came back to that record and changed Column2's value from 'Blue' to 'Red', it would have to delete the appropriate record in Table2 and then insert the new row into Table3 and visa-versa.
Can I do this with one trigger?
Thanks
I would like to change a value after the table updates inserts a new row based on the value of that column
Table Name is: MPanel
Col Names: RID, FPID.
I want to:
If column RID='16'
Then UPDATE FPID='1'
How can I trigger that update? Would this work:???
CREATE TRIGGER dbo.MyTrigLI
ON dbo.MPanel
FOR INSERT, UPDATE
AS
BEGIN
UPDATE [MPanel]
SET
FPID='1'
WHERE (UPDATE(RID='16')
END
Hi there,
I got an approach like that:
1) Read something from DB - check the value, if true stop if false go on2) Read the second Value (another SQL Statement) - check the value etc.
Now I could open the connection at 1) and if I have to go to 2) I leave the connection open and use the same connection at 2). Is it ok to do that?
The other scenario would be opening a connection at 1), immediately close it after I read the value and open a new connection at 2).
Thanks for the input!
Hey,
I'm new to this whole SQL Server 2005 thing as well as database design and I've read up on various ways I can integrate business constraints into my database. I'm not sure which way applies to me, but I could use a helping hand in the right direction.
A quick explanation of the various tables I'm dealing with:
WBS - the Work Breakdown Structure, for example: A - Widget 1, AA - Widget 1 Subsystem 1, and etc.
Impacts - the Risk or Opportunity impacts for the weights of a part/assembly. (See Assemblies have Impacts below)
Allocations - the review of the product in question, say Widget 1, in terms of various weight totals, including all parts. Example - September allocation, Initial Demo allocation, etc. Mostly used for weight history and trending
Parts - There are hundreds of Parts which will eventually lead to thousands. Each part has a WBS element. [Seems redundant, but parts are managed in-house, and WBS elements are cross-company and issued by the Government]
Parts have Allocations - For weight history and trending (see Allocations). Example, Nut 17 can have a September 1st allocation, a September 5th allocation, etc.
Assemblies - Parts are assemblies by themselves and can belong to multiple assemblies. Now, there can be multiple parts on a product, say, an unmanned ground vehicle (UGV), and so those parts can belong to a higher "assembly" [For example, there can be 3 Nut 17's (lower assembly) on Widget 1 Subsystem 2 (higher assembly) and 4 more on Widget 1 Subsystem 5, etc.]. What I'm concerned about is ensuring that the weight roll-ups are accurate for all of the assemblies.
Assemblies have Impacts - There is a risk and opportunity impact setup modeled into this design to allow for a risk or opportunity to be marked on a per-assembly level. That's all this table represents.
A part is allocated a weight and then assigned to an assembly. The Assemblies table holds this hierarchical information - the lower assembly and the higher one, both of which are Parts entries in the [Parts have Allocations] table.
Therefore, to ensure proper weight roll ups in the [Parts have Allocations] table on a per part-basis, I would like to check for any inserts, updates, deletes on both the [Parts have Allocations] table as well as the [Assemblies] table and then re-calculate the weight roll up for every assembly. Now, I'm not sure if this is a huge performance hog, but I do need to keep all the information as up-to-date and as accurate as possible. As such, I'm not sure which method is even correct, although it seems an AFTER DML trigger is in order (from what I've gathered thus far). Keep in mind, this trigger needs to go through and check every WBS or Part and then go through and check all of it's associated assemblies and then ensure the weights are correct by re-summing the weights listed.
If you need the design or create script (table layout), please let me know.
Thanks.
I am accessing SQL2005 with C# code using OleDbConnection.
A try and catch block catches the following error once a while between the Open() and Close() of the connection:
ExecuteNonQuery requires an open and available Connection. The connection's current state is closed.
I do not even have any idea where to start to debug this. The ExecuteNonQuery() runs a delete SQL query. It works 99.9% of the time. I do not see anything wrong when this error happens.
Any hint would be greatly appreciated.
In my ssis package,
I have a DSN connection like this: "DSN=myDSNname". Which decide from i have to pull the data.
By using OLE DB Source Editor, I want to assign that ODBC Connection to it.
By data source Reader i can achive this but where i have to pass the hard-code SQL Query that i don't want.
i'm using the variable for dynamic SQL command.
Thanks.

I want to be able to create a trigger that updates table 2 when a row is inserted into table 1. However I€™m not sure how to increment the ID in table 2 or to update only the row that has been inserted.

I want to be able to create a trigger so that when a row is inserted into table A by a specific user then the ID will appear in table B. Is it possible to find out the login id of the user inserting a row?
I believe the trigger should look something like this:
create trigger test_trigger
on a
for insert
as
insert into b(ID)
select i.id
from inserted i
where
--specific USER
This problem is being seen on SQL 2005 SP2 + cumulative update 4
I am currently successfully using the output clause of an insert statement to return the identity values for inserted rows into a table variable
I now need to add an "instead of insert" trigger to the table that is the subject of the insert.
As soon as I add the "instead of insert" trigger, the output clause on the insert statement does not return any data - although the insert completes successfully. As a result I am not able to obtain the identities of the inserted rows
Note that @@identity would return the correct value in the test repro below - but this is not a viable option as the table in question will be merge replicated and @@identity will return the identity value of a replication metadata table rather than the identity of the row inserted into my_table
Note also that in the test repro, the "instead of insert" trigger actually does nothing apart from the default insert, but the real world trigger has additional code.
To run the repro below - select each of the sections below in turn and execute them
1) Create the table
2) Create the trigger
3) Do the insert - note that table variable contains a row with column value zero - it should contain the @@identity value
4) Drop the trigger
5) Re-run the insert from 3) - note that table variable is now correctly populated with the @@identity value in the row
I need the behaviour to be correct when the trigger is present
Any thoughts would be much appreciated

Hello, everyone
I need to create a trigger to update a FLAG column by row modification. The table likes,
Col1FLAG
a0
b0
c0
d0
e0
If "a" in Col1 is changed, the "0" in same row (First row) should be changed to '1'. Other FLAG values should not be changed. The same rule for other row.
Anyhelp will be approciated.
Thanks a lot

Hi
I am trying to use multiple insert for a table T1 to add multiple rows.
Ti has trigger for insert to add or update multiple rows in Table T2.
When I provide multiple insert SQL then only first insert works while rest insert statements does not work
Anybody have any idea about why only one insert works for T1
Thanks
can i make a trigger to fire based on given date and time?

Hello!
This code sample stops when I try to open a connection (see below). Ther error message reads "pipe provider , error 40". The help suggests that the credentials are wrong. I don´t think so, could there be another problem? Tough question but, I would appreciate any help.
System.Data.SqlClient.SqlConnection sqlConnection1 =

string sql1 = Session["txtFirstName"].ToString();
string sql2 = Session["txtLastName"].ToString();
cmd.CommandText = "INSERT dbo.Member (mbrFirstName, mbrLastName) VALUES (sql1, sql2)";
cmd.Connection = sqlConnection1;
sqlConnection1.Open(); //EXCEPTION HERE!!!
cmd.ExecuteNonQuery();

One of my table called as 'customertable' contains following fields
customername, emailid, subscriptionendperiod
Example records are:
david, david@john.com, 12/20/2005(mm/dd/yyyy format).
My question is that: Just one month before subscriptionendperiod that is on 11/20/2005(mm/dd/yyyy) an automatic email should go to david@john.com with the message 'Your subscription period ends on 12/20/2005'
How to write trigger for this.
Please Note : No ASP code is invloved in this.
Only MSSQL coding to be done.
Regards
Do triggers work on the field level or only for full table updates, etc...?
I want to have a trigger that will change a field on another table based on the update of a specific field on a table.
Could anyone provide a sample please, if this is possible?
Thank you!
Hi, Has somebody had a problem like this before? Exception Details: System.Data.SqlClient.SqlException:
An error has occurred while establishing a connection to the server.
When connecting to SQL Server 2005, this failure may be caused by the
fact that under the default settings SQL Server does not allow remote

open a connection to SQL Server) That's part of the code: SqlConnection con; string sql; SqlCommand cmd; con=new SqlConnection("Data Source=elf/SQLEXPRESS;Initial Catalog=logos;Integrated Security=SSPI;"); sql="SELECT max(id_kandydat) from Kandydat"; con.Open(); cmd=new SqlCommand(sql,con); int id = Convert.ToInt32(cmd.ExecuteScalar()); con.Close(); SqlDataSource7.InsertCommand="INSERT INTO Kandydat_na_Kierunek(id_kandydat, id_kierunku, id_stan) VALUES ("+"'"+id+"'"+","+"'"+DropDownList1.SelectedValue+"'"+","+'1'+");"; I don't really get it. I'm nearly 100% sure that before some changes in my project this had worked perfectly. Does anybody have any idea how to make it work again? I would be very grateful for any help. And, yesy, I know it is quite common error, but proposed solution found didn't help.Regards,N.
Hello, I have always closed my db connections asap after opening them and have always thought this was the best practice. But now I am wondering if I can just leave the connection open.
I created a windows service which runs on a timer and executes every 5 seconds. The problem is that the code takes longer than that to process and the code may be executing three times at once. Im worried that since I use the same connection each time the code executes that a connection opened by the first run through may be closed or reopened by the second or third running of the code resulting in an error. The connection is opened and closed about 10 times each time the timer event fires. Should I open the connection once and leave it open when the service is started and close it when it is stopped or on any error?
Thanks

I am developing a web service that uses a sql data connection.
The sql database is on a server, and the development version of my web service is on my pc.
I can connect/access the data accross my network when I run the service on my PC, but as soon as I put the web service onto the server(with the sql) it displays, the service wont function - error: 40 - could not open a connection....
I presume that sql is configured correctly as I am recieving data back when I request it accross the network. I dont understand why it wont work when I have the service on the server with the sql?
Any help will be appreciated.
tried to install SQL Server 2005 in a fresh installed Windows 2003 SP2. And this server is a workgroup member, not a member of a domain.
The services (Database service, integration service, reporting services and so on) work fines, but I could not connect to server
I checked the log, I found the following error,error :40-Could not connect to SQL Server(Microsoft SQL Server,Error-1231).
I never had this problem and this time, I really got the trouble and do not have solution.
Who have ever encounter this problem? Or someone can help me?
Thanks.

Hi,
I hope someone can help me with this.
I have created a data reader to loop thru a table and build an update statement.
Now I need to execute this statement in the datareader loop but the connection object is in use.
I tried creating another connection object but get an error:
"The context connection is already in use."
Is there a way to open another connection while the main context connection is open.
Just to make it clear, I do not want to read all the rows into memory first and then call update, it has to
happen for each iteration of the datareader.
Thanks.

this software is written in c/java (i think).
my supervisor advised me i could experiment socketing/porting the software through port 80 somehow so that i may communicate with the database.
can any one give me any info on software/techniques if there are any out there?
thanks in advance.
