This is a simple forum, it has several topics (that the users can create), when a user create a topic, its stored in forum_topics. The user can then view the topic and post a response that is store in forum_answer, the user can also add this to his favorite list, forum_favorites is simple, contains a TopicID that refers to the topic, a username of the user that has the topic on his favorite list and a auto increment id to be able to delete specified topic favorites.
Now my question is: when a user posts a answer to Topic X, i want a predefined message to be sent to post_inbox for all the users that has Topic X in their favorite list.
How can i get MS SQL 2005 to get all the users from Topic X and then loop thru them and insert a new post into post_inbox?
I'm working on inserting data into a table in a database. The table has two separate triggers, one for insert and one for update (I don't like it this way, but that's how it's been for years). When there is a normal insert, done via a program, it looks like the triggers work fine. When I run an insert manually via a script, the first insert trigger will run, but the update trigger will fail. I narrowed down the issue to a root cause.
This root issue is due to both triggers using the same temporary table name. When the second trigger runs, there's an error stating that a few columns don't exist. I went to my test server and test db and changed the update trigger so that the temporary table is different than the insert trigger temporary table, the triggers work fine. The weird thing is that if the temporary table already exists, when the second trigger tries to create the temporary table, I would expect it to fail and say that it already exists.I'm probably just going to update the trigger tonight and change the temporary table name.
I've been reading the docs and playing around, but I'm still notgetting the difference. For instance,create table a(i int check(i>0))create table a_src(i int)gocreate unique index ai on a(i) with IGNORE_DUP_KEYgoinsert into a_src values(1)insert into a_src values(1)insert into a_src values(2)--insert into a_src values(-1)gocreate trigger a4ins on afor insertasselect * from insertedgocreate trigger afterins on aafter insertasselect * from insertedgoinsert into a select * from a_srcgodrop table adrop table a_srcI'm gettingi-----------12(2 row(s) affected)Server: Msg 3604, Level 16, State 1, Procedure a4ins, Line 4Duplicate key was ignored.i-----------12(2 row(s) affected)even the inserted quasi tables are identical.If I uncomment insert into a_src values(-1), I'm gettingServer: Msg 547, Level 16, State 1, Line 1INSERT statement conflicted with COLUMN CHECK constraint'CK__a__i__58FC18A6'. The conflict occurred in database 'ABC_1COMPEE',table 'a', column 'i'.The statement has been terminated.without any output from either trigger.So,in which situations will FOR INSERT be useful while AFTER INSERT won'tdo?in which situations will AFTER INSERT be useful while FOR INSERT won'tdo?
I've had a look at this thread - http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=104399&SiteID=1 - but it's a bit old so I thought I'd try to clarify a couple of things.
I have a data flow which inserts or updates a table in a SQL 2000 database.
The insert is done via an OLE DB destination and the update is done via an OLE DB Command.
As stated in the previous thread, when these commands run concurrently issues arise with blocking etc.
The only way I've managed to get around it is by setting the access mode of the insert to OpenRowset.
So 2 questions:
1) Does anyone know how this problem occurrs and what the best way to get around it is?
2) Are there issues around NOT using the fast load options - I've read stuff about the double-byte character set etc but I admit I don't quite understand it.
I issue an insert statement to the db. While I am getting a return value of 1 (1 row was affected) the values never show up into the db when I open the DB in access. However, I can see the data when it does an SQL select inside the program. So for instance, I do an insert into ORDER values (1, 12, 5.99). (1 = item ID, 12 = quantity, 5.99 = price). I then do a select * from Order, and I get those values back. When I open the DB in access, in between doing the insert and the select, I dont see the values there either. It is like it is making a temporary copy of the DB in memory during the execution only. When I close the program and re-F5, the data is no longer there. Maybe we need some kind of commit transaction? What am I doing wrong? I am using VB.Net 2005/MS Access 2003. Here is the relevant code :
Private m_Connection As OleDbConnection
''' <summary>
''' Defines the path to the database.
''' </summary>
''' <remarks></remarks>
#If CONFIG = "Debug" Then
Public Const DB_PATH As String = "DBsDB_Test.mdb"
#ElseIf CONFIG = "Release" Then
Public Const DB_PATH As String = "DBsDB_Production.mdb"
#End If
Sub connect(ByVal p_path As String) Implements IPartyDBase.connect
Dim connect_string As String = "Provider=Microsoft.Jet.OLEDB.4.0;" _
& "Data Source=" & p_path
m_Connection = New OleDbConnection(connect_string)
Throw New Exception("Bad addStockToDB into Stock " & tempInt)
End If
End Sub
Sub anotherSub
p_dbase.connect(PartyDBaseAccess.DB_PATH)
p_dbase.someSub()
p_dbase.close()
End Sub
Edit : During execution, looking under bin/debug/DBs, there is a copy of the database that has all the transactions I did during execution... but the actual DB isnt being updated/copied over.
Wondering what's the preferred method for this. I've got a scenario that a user is updating some content on a page and I need to update my word catalogs for my search feature. I have some code currently to filter out words that are too small, make sure there are no duplicates and to count how many occurrences there are of each. What I'm wondering is, does it make more sense to do a loop in my code to run all the insert commands to place the new words in the database, should I try sticking them together in one string and parse them when they get up there or is there a better method someone can suggest?
I've just finished configuring the SELECT command for the SqlDataSource in my ASP.NET 2.0 web app. It works fine and runs against a SQL Server 2005 database, using a stored procedure that I've written. So, then I went to configure the SqlDataSource for the UPDATE and INSERT commands, and I've written two SP's for those as well. In the designer the second form of the wizard asks for the Select statement. I've already given that for the SELECT statement in the third form, and I also select the INSERT tab to specify the SP I want to use for inserting data and the UPDATE tab to specify the SP I want to use for updating data. However, there appears to be no way that I can specify what the parameters are supposed to be for anything other than the SELECT command, through the designer. Is that correct, or have I missed something?
Hi there I' d like to make a trigger which will come with some kind of message ( maybe jscript?) or printout, each time I insert new client into the Client table. Clent table has ClientID, ClientName, Address, EMail, and ContactPerson. Please help
I have written an Insert Trigger to examine newly inserted records and set some values. However, each time a record is inserted, all records are checked. How can I make the trigger work only on newly inserted records?
I have a situation where I need to create an insert trigger on table a which will create a corresponding record in table b. However before I insert the record i must obtain the max value for the record in table b and increment it by one. I have all this working. My question is if I just put a begin and commit with this statement is there a chance that when 2 users insert at the same time the max value may be incorrect say for instance
CREATE TRIGGER tr_cms_prov_ins ON provider FOR INSERT as declare @ndentPrid char(3), @nxtgenPrid char(7), @fname varchar(40), @lname varchar(40) begin tran select @ndentPrid = max(provider_id) from providerdnt if @ndentPrid is null set @ndentPrid = 1 else set @ndentPrid = @ndentPrid + 1
insert into dental..provider (provider_id, first_name, last_name, collections_go_to) select @ndentPrid, first_name, last_name','YYYYYYYYYYYYYYYNNNNN' from inserted commit tran
Will this do it or do I need to enforce some type of locking to handle the max value. There are no inserts into table b directly only by the trigger insert on table a
Hello all, I'm in the process of debugging a trigger i've written (which hasn't been any fun) and i have a question.
records for the table with the trigger are only inserted from a SP using an INSERT INTO ... SELECT statement. Multiple rows at a time.
question is.. does the trigger fire once for that insert into ... select or does it fire for each new row inserted by that statement. I was under the impression that it fires for each row but i'm not sure now because the table the trigger inserts to only has one row after the SP is run.
I created a trigger which looks like Create TRIGGER UpdateGenTables3 ON AWSWQ_Quizzes After insert as Begin SET NOCOUNT ON declare @TableName varchar(20),@Title varchar(20),@code varchar(20),@Gcode varchar(20),@uppercode varchar(20), @Description varchar(50) DECLARE DemoCursor CURSOR FOR Select QuizID,QuizTitle from AWSWQ_Quizzes group by QuizID,QuizTitle OPEN DemoCursor FETCH Next From DemoCursor INTO @code,@Title WHILE @@FETCH_STATUS = 0 BEGIN
INSERT INTO gen_tables (TABLE_NAME, CODE, SUBSTITUTE,UPPER_CODE,DESCRIPTION,OBSOLETE_DESCRIPTION) VALUES ('PRE_REQ_TESTS', @code, '', @code, @title, '') FETCH Next From DemoCursor INTO @code,@Title END CLOSE DemoCursor DEALLOCATE DemoCursor
end
The problem with my trigger is .I am not able to insert into my table AWSWQ_Quizzes the error i get when i try to insert is
Violation of PRIMARY KEY constraint 'pkGen_TablesTABLE_NAME'. Cannot insert duplicate key in object 'Gen_Tables'. The statement has been terminated. ---> System.Data.SqlClient.SqlException: Violation of PRIMARY KEY constraint 'pkGen_TablesTABLE_NAME'. Cannot insert duplicate key in object 'Gen_Tables'.
I have been trying to implement a trigger that is fired when a record is inserted in a table, provided that certain fields in the inserted record meet specific criteria (what you'd find in a where clause). All examples I have come across so far involve cases where the trigger is fired off everytime there is an insert regardless of what values are being inserted.
Basically, Assume a table "Address" with colums House Number, Street Name, City, State, Zip Code. How do I make my trigger fire ONLY when a record with City = 'Boston' is inserted??
How do I set up an insert trigger to copy all of the inserted data to another table? In other words, when someone adds a new paramater in the params table, I want to automatically create a matching set of data in the goals table. Thanks,Krista
SQL Server 2000 : I have a series of tables which all have the samestructure. When any of these tables are modified I need to syncrhoniseall of those modifications with one other table wich is a sort of mergeof the individual tables with one extra column.For most of these tables this is not a problem. The problem arriveswhen one of the tables has an ntext column which obviously can not beused in an update or insert trigger.Here's an example of one of them:CREATE TABLE tblImages(ID INT IDENTITY(1,1) PRIMARY KEY,Inventory nvarchar(8) NOT NULL,Coll nvarchar(8) NOT NULL,ImageFile nvarchar(128) NOT NULL,ImageNotes ntext NULL,TS timestamp NULLCONSTRAINT U_Images UNIQUE NONCLUSTERED (ItemCode, Inventory, Coll,ImageFile)I then had created an update trigger which looked like this:CREATE TRIGGER COLLNAME_UTRIGGER ON COLLNAME_ImagesFOR UPDATEASBEGINUPDATE tblImages SETInventory = inserted.Inventory,Coll = 'COLLNAME',ImageFile = inserted.ImageFileName,FROM inserted INNER JOIN tblImages ON inserted.ItemCode =tblImages.ItemCode ANDinserted.Invventory = tblImages.Invventory AND tblImages.Coll ='COLLNAME' ANDinserted.ImageFileName = tblImages.ImageFileUPDATE tblImagesSET ImageNotes=inserted.NotesFROM inserted INNER JOIN tblImages ON inserted.ItemCode =tblImages.ItemCode ANDinserted.Inventory= tblImages.Inventory AND tblImages.Coll ='COLLNAME' ANDinserted.ImageFileName = tblImages.ImageFileEND " & vbCrLf)The first update in my trigger, be it an update or insert trigger,works fine. It crashes with the "Cannot use text, ntext or imagecolumns in the 'inserted' or 'deleted' tables." error in the secondpart.I have read various messages through the Internet on this and severalof them reference using INSTEAD OF triggers and views. I have neverused those before as this is my first work with SQL 2000. None of theexamples of INSTEAD OF triggers I have seen yet use the actual insertedtables and I haven't quite understood how to use them correctly.Can someone help me with the basic syntax as this trigger is one ofseveral that I am going to have to get working.Thank you in advance for any help, assistance, suggestions or"direction pointing" you may provide.
I wrote a trigger that works fine when I insert record by record in the DB. However, when I run a Stored Proc to insert a bunch of records at the same time, the trigger only works for the last record.
Anyone has a clue or a possible solution. The trigger is well tested and works fine.
Hi everybody,I just wrote my first two triggers and from the minimal amount of testing Ihave done, they work! However, I was hoping I could get some feedback fromthose of you more experienced in writing triggers.Here is the first one:CREATE TRIGGER DecreInters ON InteractionFOR DELETEASdeclare @stu INTdeclare @num INTselect @stu = Student_FK from deletedselect @num = (select Inters from Student where Student_Key = @stu)UPDATE StudentSET Inters = @num - 1FROM StudentWHERE Student.Student_Key = @stuHere is the second one:CREATE TRIGGER IncreIntersON InteractionAFTER INSERTASdeclare @stu INTdeclare @num INTdeclare @last_rec INTselect @last_rec = @@IDENTITYselect @stu = (select Student_FK from Interaction where Interaction_ID =@last_rec)select @num = (select Inters from Student where Student_Key = @stu)UPDATE StudentSET Inters = @num + 1FROM StudentWHERE Student.Student_Key = @stuAre there any shortcuts I could use or things I could do to make thesetriggers more efficient. Please give me some feedback and let me know ofany problems that might possibly be caused due to my doing this improperly.Thanks ahead,Corey
I recently moved a database from a SQL server 2005 box to new server running SQL server 2012. The update/insert triggers that were working on the tables to handle referential integrity checking are no longer working. Running the same database on SQL Server 2008 and everything works.
Here is one of the trigger that throws the error 44446
USE [M2Data] GO /****** Object:Â Trigger [dbo].[tblContacts_UTrig]Â Â Â Script Date: 3/11/2014 9:07:13 AM ******/ SET ANSI_NULLS ON
[code]....
I have verified that there is a matching key in tblCompanys. Also, when I run a query to update tblContacts the error message appears but the update does take. If I try and edit the row directly by selecting edit top 200 rows - the error message appears and the update does NOT take.
These triggers were probably added to the database during an upsize from MS Access to SQL Server 7 way back. What am I missing - is it something in the syntax?
I want to be able to duplicate every single record that is inserted or updated in a particular table to another table, but not the delete. Is the best way to set-up a trigger? If so can anyone provide me with an example of how to do this? Also could you just duplicate certain columns in the row I would you have to do all columns?

I have a web form with a text field that needs to take in as much as the user decides to type and insert it into an nvarchar(max) field in the database behind. I've tried using the new .write() method in my update statement, but it cuts off the text after a while. Is there a way to insert/update in SQL 2005 this without resorting to Bulk Insert? It bloats the transaction log and turning the logging off requires a call to sp_dboptions (or a straight-up ALTER DATABASE), which I'd like to avoid if I can.
An insert statement was not inserting all the data into a table. Found it very strange as the other fields in the row were inserted. I ran SQL profiler and found that sql statement had all the fields in the insert statement but some of the fields were not inserted. Below is the sql statement which is created dyanmically by a asp.net C# class. The columns which are not inserted are 'totaltax' and 'totalamount' ...while the 'shipto_name' etc...were inserted.there were not errors thrown. The sql from the code cannot be shown here as it is dynamically built referencing C# class files.It works fine on another test database which uses the same dlls. The only difference i found was the difference in date formats..@totalamount=1625.62,@totaltax=125.62are not inserted into the database.Below is the statement copied from SQL profiler.exec sp_executesql N'INSERT INTO salesorder(billto_city, billto_country, billto_line1, billto_line2, billto_name,billto_postalcode, billto_stateorprovince, billto_telephone, contactid, CreatedOn, customerid, customeridtype,DeletionStateCode, discountamount, discountpercentage, ModifiedOn, name, ordernumber,pricelevelid, salesorderId, shipto_city, shipto_country,shipto_line1, shipto_line2, shipto_name, shipto_postalcode, shipto_stateorprovince,shipto_telephone, StateCode, submitdate, totalamount,totallineitemamount, totaltax ) VALUES(@billto_city, @billto_country, @billto_line1, @billto_line2,@billto_name, @billto_postalcode, @billto_stateorprovince, @billto_telephone, @contactid, @CreatedOn, @customerid,@customeridtype, @DeletionStateCode, @discountamount,@discountpercentage, @ModifiedOn, @name, @ordernumber, @pricelevelid, @salesorderId,@shipto_city, @shipto_country, @shipto_line1, @shipto_line2,@shipto_name, @shipto_postalcode, @shipto_stateorprovince, @shipto_telephone,@StateCode, @submitdate, @totalamount, @totallineitemamount, @totaltax)',N'@billto_city nvarchar(8),@billto_country nvarchar(13),@billto_line1 nvarchar(3),@billto_line2 nvarchar(4),@billto_name nvarchar(15),@billto_postalcode nvarchar(5),@billto_stateorprovince nvarchar(8),@billto_telephone nvarchar(3),@contactid uniqueidentifier,@CreatedOn datetime,@customerid uniqueidentifier,@customeridtype int,@DeletionStateCode int,@discountamount decimal(1,0),@discountpercentage decimal(1,0),@ModifiedOn datetime,@name nvarchar(33),@ordernumber nvarchar(18),@pricelevelid uniqueidentifier,@salesorderId uniqueidentifier,@shipto_city nvarchar(8),@shipto_country nvarchar(13),@shipto_line1 nvarchar(3),@shipto_line2 nvarchar(4),@shipto_name nvarchar(15),@shipto_postalcode nvarchar(5),@shipto_stateorprovince nvarchar(8),@shipto_telephone nvarchar(3),@StateCode int,@submitdate datetime,@totalamount decimal(6,2),@totallineitemamount decimal(6,2),@totaltax decimal(5,2)',@billto_city=N'New York',@billto_country=N'United States',@billto_line1=N'454',@billto_line2=N'Road',@billto_name=N'Hillary Clinton',@billto_postalcode=N'10001',@billto_stateorprovince=N'New York',@billto_telephone=N'124',@contactid='8DAFE298-3A25-42EE-B208-0B79DE653B61',@CreatedOn=''2008-04-18 13:37:12:013'',@customerid='8DAFE298-3A25-42EE-B208-0B79DE653B61',@customeridtype=2,@DeletionStateCode=0,@discountamount=0,@discountpercentage=0,@ModifiedOn=''2008-04-18 13:37:12:013'',@name=N'E-Commerce Order (Before billing)',@ordernumber=N'BRKV-CC-OKRW5764YS',@pricelevelid='B74DB28B-AA8F-DC11-B289-000423B63B71',@salesorderId='9CD0E11A-5A6D-4584-BC3E-4292EBA6ED24',@shipto_city=N'New York',@shipto_country=N'United States',@shipto_line1=N'454',@shipto_line2=N'Road',@shipto_name=N'Hillary Clinton',@shipto_postalcode=N'10001',@shipto_stateorprovince=N'New York',@shipto_telephone=N'124',@StateCode=0,@submitdate=''2008-04-18 14:37:10:140'',@totalamount=1625.62,@totallineitemamount=1500.00,@totaltax=125.62

Hello, I'm new to the forum and new to SQL, ASP.NET, etc. I am creating an intranet site for my company in VS 2005 and have run into a very annoying problem that I can't seem to solve. I have tried Googling it and came up empty. I have a database in SQL Express 2005 and my website will be accessing several tables within the database. I can retrieve info just fine and I can update, delete, etc just fine using gridview or other prebuilt tools, but when I add a few text boxes and wire a button to the SqlDataSource.Insert() command, I get a new record that is full of null values except for the identity key I have set. The kicker is that I am also using a master page and when I duplicate the web page without the master page link, everything works just fine. The following snippets show what I'm doing:<InsertParameters><asp:FormParameter Name="Name" Type="String" FormField="txtName" /><asp:FormParameter Name="Location" Type="String" FormField="ddlLocation" /><asp:FormParameter Name="Issue" Type="String" FormField="txtProblem" /></InsertParameters>Of course I match the formfields to the text boxes, create an onclick event for my button, the sqldatasource is configured correctly, it just doesn't work with the master page no matter what I do. Any help would be appreciated. Thanks
On my site users can register using ASP Membership Create user Wizard control. I am also using the wizard control to design a simple question and answer form that logged in users have access to. it has 2 questions including a text box for Q1 and dropdown list for Q2. I have a table in my database called "Players" which has 3 Columns UserId Primary Key of type Unique Identifyer PlayerName Type String PlayerGenre Type Sting
On completing the wizard and clicking the finish button, I want the data to be inserted into the SQl express Players table. I am having problems getting this to work and keep getting exceptions. Be very helpful if somebody could check the code and advise where the problem is??
To match the answers to the user I get the UserId and insert this into the database to.protected void Wizard1_FinishButtonClick(object sender, WizardNavigationEventArgs e) { SqlDataSource DataSource = (SqlDataSource)Wizard1.FindControl("InsertArtist1"); MembershipUser myUser = Membership.GetUser(this.User.Identity.Name); Guid UserId = (Guid)myUser.ProviderUserKey;String Gender = ((DropDownList)Wizard1.FindControl("PlayerGenre")).SelectedValue; DataSource.InsertParameters.Add("UserId", UserId.ToString());DataSource.InsertParameters.Add("PlayerGenre", Gender.ToString()); DataSource.Insert();
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

I decided to change over from Microsoft Access Database file to the New SQLServerCe Compact edition. Although the reading of data from the database is greatly improved, the inserting of the new rows is extremely slow.
I was getting between 60 to 70 rows per sec using OLEDB and an Access Database but now only getting 14 to 27 rows per sec using SQLServerCe.
I have tried the below code changes and nothing seams to increase the speed, any help as I would prefer to use SQLServerCe as the database is much smaller and I€™m use to SQL Commands.
